If you're interested in learning more, get started at highlight.io . Check out the React Native example app and Highlight code snippets to follow along. OpenTelemetry is an open-source observability framework that provides tools, APIs, and SDKs to collect, process, and export telemetry data like traces, metrics, and logs from applications. It is designed to help developers monitor and troubleshoot distributed systems by providing standardized data formats and integration points for observability tools. If you're new to OpenTelemetry, you can learn more about it here . Today, we'll go through a guide to using OpenTelemetry in React Native, including the high-level concepts as well as how to send traces, errors, and logs to your OpenTelemetry backend of choice. Provider A provider is the API entry point that holds the configuration for telemetry data. The provider is responsible for setting up the environment and ensuring that all necessary configurations are in place. This can include configuring a vendor specific api key, or something as simple as setting the service name and environment. In our case, we will be using a TraceProvider to send traces that will be processed by the Highlight backend and converted to logs, errors, and traces. In our example, the TracerProvider creates a resource, that builds attributes that we want to include with every trace. This includes the highlight.project_id to let Highlight know which project the traces below to, and other identifying data, such as service name and environment to help with monitoring and debugging. Here's a quick example of what this looks like in code: import { BasicTracerProvider } from '@opentelemetry/sdk-trace-base' import { Resource } from '@opentelemetry/resources' const resource = new Resource({ 'highlight.project_id': '<YOUR_PROJECT_ID>', 'service.name': 'reactnativeapp', 'environment': 'production', }) const tracerProvider = new BasicTracerProvider({ resource }) Exporter An exporter sends the telemetry data to the backend. This is where you configure the endpoint and any other necessary settings related to the backend you're sending data to. In our example, we built a custom exporter as a workaround to some OpenTelemetry package issues with the React Native's bundler, Metro. A bundler-based solution is also in progress to use OpenTelemetry's OTLPTraceExporter , and substitute out our custom exporter. Here's an example of how you might build a custom React Native exporter class that serializes and sends traces over http. Notice the majority of logic is serializing the batched spans: import { SpanExporter, ReadableSpan, TimedEvent, } from '@opentelemetry/sdk-trace-base' import type { Link, Attributes } from '@opentelemetry/api' import { ExportResultCode } from '@opentelemetry/core' type KeyValue = { key: string value: KeyValue } class ReactNativeOTLPTraceExporter implements SpanExporter { url: string constructor(options: { url: string }) { this.url = options.url this._buildResourceSpans = this._buildResourceSpans.bind(this) this._convertEvent = this._convertEvent.bind(this) this._convertToOTLPFormat = this._convertToOTLPFormat.bind(this) this._convertLink = this._convertLink.bind(this) this._convertAttributes = this._convertAttributes.bind(this) this._convertKeyValue = this._convertKeyValue.bind(this) this._toAnyValue = this._toAnyValue.bind(this) } export(spans: ReadableSpan[], resultCallback: any) { fetch(this.url, { method: 'POST', headers: { 'Content-Type': 'application/json' }, body: this._buildResourceSpans(spans), }) .then(() => { resultCallback({ code: ExportResultCode.SUCCESS }) }) .catch((err) => { resultCallback({ code: ExportResultCode.FAILED, error: err }) }) } shutdown() { return Promise.resolve() } _buildResourceSpans(spans: ReadableSpan[] = []) { const resource = spans[0]?.resource const scope = spans[0]?.instrumentationLibrary return JSON.stringify({ resourceSpans: [ { resource: { attributes: resource.attributes ? this._convertAttributes(resource.attributes) : [], }, scopeSpans: [ { scope: { name: scope?.name, version: scope?.version, }, spans: spans.map(this._convertToOTLPFormat), }, ], }, ], }) } _convertToOTLPFormat(span: ReadableSpan) { const spanContext = span.spanContext() const status = span.status return { traceId: spanContext.traceId, spanId: spanContext.spanId, parentSpanId: span.parentSpanId, traceState: spanContext.traceState?.serialize(), name: span.name, // Span kind is offset by 1 because the API does not define a value for unset kind: span.kind == null ? 0 : span.kind + 1, startTimeUnixNano: span.startTime[0] * 1e9 + span.startTime[1], endTimeUnixNano: span.endTime[0] * 1e9 + span.endTime[1], attributes: span.attributes ? this._convertAttributes(span.attributes) : [], droppedAttributesCount: span.droppedAttributesCount || 0, events: span.events?.map(this._convertEvent) || [], droppedEventsCount: span.droppedEventsCount || 0, status: { code: status.code, message: status.message, }, links: span.links?.map(this._convertLink) || [], droppedLinksCount: span.droppedLinksCount, } } _convertEvent(timedEvent: TimedEvent) { return { attributes: timedEvent.attributes ? this._convertAttributes(timedEvent.attributes) : [], name: timedEvent.name, timeUnixNano: timedEvent.time[0] * 1e9 + timedEvent.time[1], droppedAttributesCount: timedEvent.droppedAttributesCount || 0, } } _convertLink(link: Link) { return { attributes: link.attributes ? this._convertAttributes(link.attributes) : [], spanId: link.context.spanId, traceId: link.context.traceId, traceState: link.context.traceState?.serialize(), droppedAttributesCount: link.droppedAttributesCount || 0, } } _convertAttributes(attributes: Attributes) { return Object.keys(attributes).map((key) => this._convertKeyValue(key, attributes[key]), ) } _convertKeyValue(key: string, value: any): KeyValue { return { key: key, value: this._toAnyValue(value), } } _toAnyValue(value: any): any { const t = typeof value if (t === 'string') return { stringValue: value as string } if (t === 'number') { if (!Number.isInteger(value)) return { doubleValue: value as number } return { intValue: value as number } } if (t === 'boolean') return { boolValue: value as boolean } if (value instanceof Uint8Array) return { bytesValue: value } if (Array.isArray(value)) return { arrayValue: { values: value.map(this._toAnyValue) } } if (t === 'object' && value != null) return { kvlistValue: { values: Object.entries(value as object).map(([k, v]) => this._convertKeyValue(k, v), ), }, } return {} } } After we build our exporter, we need to create an instance with the correct url to send the traces. This is done in the example below: const otlpExporter = new ReactNativeOTLPTraceExporter({ url: 'https://otel.highlight.io:4318/v1/traces', }) Processor Finally, a processor defines any pre-processing that should be done on the created traces, such as batching, sampling, filtering or even enriching data. This is important because you may have specific needs on the machine that you're sending data from that require customization. In our example, we will use a BatchSpanProcessor to collect spans in batches and send them to the exporter, which is more efficient than sending each span individually. Here's how we initialized the BatchSpanProcessor , and registered the traceProvider: import { BatchSpanProcessor } from '@opentelemetry/sdk-trace-base' tracerProvider.addSpanProcessor(new BatchSpanProcessor(otlpExporter)) tracerProvider.register() export const tracer = tracerProvider.getTracer('react-native-tracer') Try Highlight Today Get the visibility you need Get started for free Instrumenting your application After we created our tracer, we can now use it to send Highlight.io traces, logs, and errors. We can also monkeypatch javascript's console methods, so they will send to Highlight by default. Tracing Tracing is possible by calling the created tracer 's startSpan method. This accepts a parameter for the name of the span, and returns the span itself. From there, the span can record an error, add attributes, and much more. We will signal the end of a span by calling the end method. Here is an example, assuming the tracer is exportable from a file called highlight.ts : import { tracer } from "./highlight" const span = H.tracer.startSpan('Blog Post') // ...some code span.setAttributes({ name: "How to instrument your React Native app with OpenTelemetry" }) span.recordException( new Error('this is an error in the Blog Post span'), ) span.end() Logging Logging can be sent to Highlight with a few configurations to the trace method. First, the span name should be highlight.log to let the Highlight backend know it is, in fact, a log. Second, we will pass in a log.severity and a log.message attribute to be used when constructing the log object. It is recommended you set up a log function to complete this. Here is an example of a log function below: const ConsoleLevels = { debug: 'debug', info: 'info', log: 'info', count: 'info', dir: 'info', warn: 'warn', assert: 'warn', error: 'error', trace: 'trace', } as const export const log = ( level: keyof typeof ConsoleLevels, message: string, attributes = {}, ) => { const span = tracer.startSpan('highlight.log') span.addEvent( 'log', { ...attributes, ['log.severity']: level, ['log.message']: message, }, new Date(), ) span.end() } The benefit of using this log function is being able to pass in attributes more cleanly to be searched across in Highlight. However, this will only send to Highlight and will not be recorded in the dev tools. We will set up the monkeypatch to record console logs later. After you have created your function, you can export this function to be called in your application code. import { log } from "./highlight" log("warn", "we are almost finished", { minutesRead: 10 }) Errors In our solution, errors are also sent via traces to Highlight with some configuration details. Again, we will call the trace highlight.log to ensure this trace will create a log for you in Highlight. Second, we will record an exception and add any attributes to the span. Here is an example of a error function below: export const error = (message: string, attributes = {}) => { const span = tracer.startSpan('highlight.log') span.recordException(new Error(message), new Date()) span.setAttributes(attributes) span.end() } Again, the benefit of using this error function is flexibility of passing in a custom error name as well as attributes associated with the error. Monkeypatching the console method will send any error logs to Highlight which will then be processed as an error. After you have created your function, you can export this function to be called in your application code. import { error } from "./highlight" error("user unset", { defaultAvatar: "batman" }) Autoinstrumentation of console functions The functions above are great for flexibility and customization, but maybe all you want is to report what is happening in the console to Highlight. We have you covered. We created a hook to call in your code that will monkeypatch the console methods to send to Highlight in addition to printing in the console dev tools. This should be called on app load or early on in the lifecycle of the session. Here is an example of how to monkeypatch the console methods: type ConsoleFn = (...data: any) => void let consoleHooked = false export function hookConsole() { if (consoleHooked) return consoleHooked = true for (const [level, highlightLevel] of Object.entries(ConsoleLevels)) { const origWrite = console[level as keyof Console] as ConsoleFn ;(console[level as keyof Console] as ConsoleFn) = function ( ...data: any[] ) { try { return origWrite(...data) } finally { const o: { stack: any } = { stack: {} } Error.captureStackTrace(o) const message = data.map((o) => typeof o === 'object' ? safeStringify(o) : o, ) const attributes = data .filter((d) => typeof d === 'object') .reduce((a, b) => ({ ...a, ...b }), {}) if (level === 'error') { attributes['exception.type'] = 'Error' attributes['exception.message'] = message.join('') attributes['exception.stacktrace'] = JSON.stringify(o.stack) } log(highlightLevel, message.join(' '), attributes) } } } } // https://stackoverflow.com/a/2805230 const MAX_RECURSION = 128 export function safeStringify(obj: any): string { function replacer(input: any, depth?: number): any { if ((depth ?? 0) > MAX_RECURSION) { throw new Error('max recursion exceeded') } if (input && typeof input === 'object') { for (const k in input) { if (typeof input[k] === 'object') { replacer(input[k], (depth ?? 0) + 1) } else if (!canStringify(input[k])) { input[k] = input[k].toString() } } } return input } function canStringify(value: any): boolean { try { JSON.stringify(value) return true } catch (e) { return false } } try { return JSON.stringify(replacer(obj)) } catch (e) { return obj.toString() } } In this function, we overwrite the console function if it has not been overwritten yet. It will then process the data, determine if its an error, and call the log function from above. There is some additional logic to safely stringify any data without going to deep into recursion. Finally, this can be called in your application to start recording console data to Highlight: import { hookConsole } from "./highlight" import { useEffect } from "react" // within component useEffect(() => { hookConsole() }, []) console.log("I'm sending to Highlight") Conclusion In this guide, we've gone through everything you need to use OpenTelemetry in React Native to be able to send Highlight your logs, traces, and errors. OpenTelemetry is flexible, so this solution is not the only one. Feel free to edit resources, methods, and classes to what works best for your application.

This works on websites, iOS, mobile, and desktop applications. Features Ease of use - A new visitor to your site only has to click two buttons in order to log in for the first time. X integration - The Log in with X flow can grant authorization to use X APIs on your users’ behalf. OAuth based - A wealth of client libraries and example code are compatible with the Log in with X API. Available for Browsers - If your users can access a browser, you can integrate with Log in with X. Learn about the browser sign in flow. Mobile devices - Any web-connected mobile device can take advantage of Log in with X. Learn about the mobile sign in flow. Implementing Log in with X The browser and mobile web implementations of Log in with X are based on OAuth. This page demonstrates the requests needed to obtain an access token for the sign in flow. To use the “Log in with X” flow, please go to your X app settings and ensure that the “Allow this app to be used to Sign in with X? ” option is enabled. This page assumes that the reader knows how to sign requests using the OAuth 1.0a protocol. If you want to know how to sign a request, read the Authorizing a request page. If you want to check the signing of the requests on this page, the consumer secret used is: L8qq9PZyRg6ieKGEKhZolGC0vJWLw8iEJ88DRdyOg. This value is for test purposes and will not work for real requests. The three steps for implementing Log in with X through obtaining a request token, redirecting a user, and converting a request token into an access token are listed below. Step 1 Step 2 Step 3 Step 1: Obtaining a request token To start a sign-in flow, your X app must obtain a request token by sending a signed message to POST oauth/request_token . The only unique parameter in this request is oauth_callback, which must be a URL-encoded version of the URL you wish your user to be redirected to when they complete step 2. The remaining parameters are added by the OAuth signing process. Note: Any callback URL that you use with the POST oauth/request_token endpoint will have to be registered within the X app settings in the developer portal . Example request (Authorization header has been wrapped): Copy Ask AI POST /oauth/request_token HTTP/1.1 User-Agent: themattharris' HTTP Client Host: api.x.com Accept: */* Authorization: OAuth oauth_callback="http%3A%2F%2Flocalhost%2Fsign-in-with-twitter%2F", oauth_consumer_key="cChZNFj6T5R0TigYB9yd1w", oauth_nonce="ea9ec8429b68d6b77cd5600adbbb0456", oauth_signature="F1Li3tvehgcraF8DMJ7OyxO4w9Y%3D", oauth_signature_method="HMAC-SHA1", oauth_timestamp="1318467427", oauth_version="1.0" Your app should examine the HTTP status of the response. Any value other than 200 indicates a failure. The body of the response will contain the oauth_token, oauth_token_secret, and oauth_callback_confirmed parameters. Your app should verify that oauth_callback_confirmed is true and store the other two values for the next steps. Example response (response body has been wrapped): Copy Ask AI HTTP/1.1 200 OK Date: Thu, 13 Oct 2011 00:57:06 GMT Status: 200 OK Content-Type: text/html; charset=utf-8 Content-Length: 146 Pragma: no-cache Expires: Tue, 31 Mar 1981 05:00:00 GMT Cache-Control: no-cache, no-store, must-revalidate, pre-check=0, post-check=0 Vary: Accept-Encoding Server: tfe oauth_token=NPcudxy0yU5T3tBzho7iCotZ3cnetKwcTIRlX0iwRl0& oauth_token_secret=veNRnAWe6inFuo8o2u8SLLZLjolYDmDP7SzL0YfYI& oauth_callback_confirmed=true Step 2: Redirecting the user The next step is to direct the user to X so that they may complete the appropriate flow, as described in Browser sign-in flow below. Direct the user to GET oauth/authenticate , and the request token obtained in step 1 should be passed as the oauth_token parameter. The most seamless way for a website to implement this would be to issue an HTTP 302 redirect as the response to the original “sign in” request. Mobile and desktop apps should open a new browser window or direct to the URL via an embedded web view. Example URL to redirect to: https://api.x.com/oauth/authenticate?oauth_token=NPcudxy0yU5T3tBzho7iCotZ3cnetKwcTIRlX0iwRl0 The sign in endpoint will behave in one of three ways depending on the user’s status: Signed in and approved : If the user is signed in on x.com and has already approved the calling application, they will be immediately authenticated and returned to the callback URL with a valid OAuth request token. The redirect to x.com is not obvious to the user. Signed in but not approved : If the user is signed in to x.com but has not approved the calling application, a request to share access with the calling application will be shown. After accepting the authorization request, the user will be redirected to the callback URL with a valid OAuth request token. Not signed in : If the user is not signed in on x.com, they will be prompted to enter their credentials and grant access for the application to access their information on the same screen. Once signed in, the user will be returned to the callback URL with a valid OAuth request token. Upon a successful authentication, your callback_url would receive a request containing the oauth_token and oauth_verifier parameters. Your application should verify that the token matches the request token received in step 1. Request from client’s redirect (querystring parameters wrapped): Copy Ask AI GET /sign-in-with-twitter/? oauth_token=NPcudxy0yU5T3tBzho7iCotZ3cnetKwcTIRlX0iwRl0& oauth_verifier=uw7NjWHT6OJ1MpJOXsHfNxoAhPKpgI8BlYDhxEjIBY HTTP/1.1 Host: localhost User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_6_8) AppleWebKit/535.5 (KHTML, like Gecko) Chrome/16.0.891.1 Safari/535.5 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Referer: http://localhost/sign-in-with-twitter/ Accept-Encoding: gzip,deflate,sdch Accept-Language: en-US,en;q=0.8 Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3 Step 3: Converting the request token to an access token To render the request token into a usable access token, your application must make a request to the POST oauth/access_token endpoint, containing the oauth_verifier value obtained in step 2. The request token is also passed in the oauth_token portion of the header, but this will have been added by the signing process. Example request (Authorization header wrapped): Copy Ask AI POST /oauth/access_token HTTP/1.1 User-Agent: themattharris' HTTP Client Host: api.x.com Accept: */* Authorization: OAuth oauth_consumer_key="cChZNFj6T5R0TigYB9yd1w", oauth_nonce="a9900fe68e2573b27a37f10fbad6a755", oauth_signature="39cipBtIOHEEnybAR4sATQTpl2I%3D", oauth_signature_method="HMAC-SHA1", oauth_timestamp="1318467427", oauth_token="NPcudxy0yU5T3tBzho7iCotZ3cnetKwcTIRlX0iwRl0", oauth_version="1.0" Content-Length: 57 Content-Type: application/x-www-form-urlencoded oauth_verifier=uw7NjWHT6OJ1MpJOXsHfNxoAhPKpgI8BlYDhxEjIBY A successful response contains the oauth_token, oauth_token_secret parameters. The token and token secret should be stored and used for future authenticated requests to the X API. To determine the identity of the user, use GET account/verify_credentials . Example response (response body has been wrapped): Copy Ask AI HTTP/1.1 200 OK Date: Thu, 13 Oct 2011 00:57:08 GMT Status: 200 OK Content-Type: text/html; charset=utf-8 Content-Length: 157 Pragma: no-cache Expires: Tue, 31 Mar 1981 05:00:00 GMT Cache-Control: no-cache, no-store, must-revalidate, pre-check=0, post-check=0 Vary: Accept-Encoding Server: tfe oauth_token=7588892-kagSNqWge8gB1WwE3plnFsJHAZVfxWD7Vb57p0b4& oauth_token_secret=PbKfYqSryyeKDWz4ebtY3o5ogNLG11WJuZBc9fQrQo Additional resources Browser sign in flow Mobile sign in flow Log in with X Resources Client libraries The client libraries listed at X libraries will help implement Log in with X. Use the /oauth/authenticate endpoint, as described in the previous steps. Brand Toolkit X would prefer your application to use the official X Brand Toolkit for consistent branding. Save these assets use them when creating a ‘Login with X’ button. The browser log in flow is appropriate for websites and applications which are able to open or embed a web browser. At a very high level: The application renders a “Sign in with X” link or button. The user clicks the sign in button. The current web browser is redirected to X (or a new browser is opened and directed to X). The user completes a login and authorization step at X if needed. X redirects back to an URL under the application’s control, passing authorization information for the user. X keeps track of the authorizations, so for users already signed in to X.com who have authorized the application, no UI is shown - instead, they are automatically redirected back to the application. Desktop flow To demonstrate the flows, pretend the website pictured above (“The greatest website ever created”) has implemented this API, as shown by the Sign in with X button on the landing page. When the user clicks the Sign in button, the page they see depends on whether they are signed in and whether they have previously allowed the application to access their account. When the user is signed in to x.com but has not granted access, a list of requested permissions, along with Sign In and Cancel buttons are shown. When the user is not signed in to x.com input fields for a username and password will be shown. Note that even if the user has already granted access to the application, the list of permissions will still be shown. After the user inputs valid credentials (if needed) and clicks “Sign In”, X will redirect the user to the website which started the sign in flow. In the case where the user is already signed in to x.com and has granted access to the website, this redirect happens immediately. The UI flow for mobile web browsers works exactly like the Browser sign in flow, but is optimized for mobile browsers.

https://www.thepythoncodingstack.com/p/parkruns-pythons-enumerate-and-zip | Parkruns, Python’s enumerate and zip, and Why Python Loops Are Different from Other Languages • [Club] Subscribe Sign in The Club Parkruns, Python’s enumerate and zip, and Why Python Loops Are Different from Other Languages • [Club] Don’t forget about enumerate() and zip() when coding in Python • A short post Stephen Gruppetta Jan 09, 2026 ∙ Paid 4 2 1 Share If you live in the UK, you’re probably familiar with the Parkrun tradition: a friendly 5k run held every Saturday morning in hundreds of parks across the UK. Runners range from Olympians to people trying to lose some weight. It’s a well-oiled format replicated across all 893 Parkrun locations . And here’s how they deal with the finish line logistics. Runners don’t wear bibs with numbers. When they cross the finish line, they enter a “funnel” marked by plastic cones and are handed a token with their position number. They then proceed to another official, who scans their personal barcode, which runners carry in their pockets or on a wristband, and the position token they received a few seconds earlier. This process matches the runner with their finishing position. What’s this got to do with Python loops? And how does it help us understand why Python does loops differently from other languages? First step, let’s create the Parkrun funnel. I’ll just put the first five finishers in this example: >>> funnel = [”Jonathan”, “Michael”, “Samantha”, “Jessica”, “Daniel”] Now, here’s something you definitely know already because it’s always one of the first things you’re taught when learning Python: Don’t loop through this list like this: # Avoid this when coding in Python >>> i = 0 >>> while i < len(funnel): ... name = funnel[i] ... print(name) ... i += 1 ... Jonathan Michael Samantha Jessica Daniel This style mimics how other languages may work: you manually define and increment the index. To be fair, most people who shift from other languages are more likely to write the following version at some point: # Also best to avoid this in Python >>> for i in range(len(funnel)): ... name = funnel[i] ... print(name) ... Jonathan Michael Samantha Jessica Daniel This version may seem more Pythonic since it uses Python tools such as range() , but still fails to make the most of Python’s iteration protocol. The Pythonic way of looping through this list is the following: >>> for name in funnel: ... print(name) ... Jonathan Michael Samantha Jessica Daniel A question that’s often asked but rarely answered is: Why is this version preferred over the other two? I’ll write another short post to answer this question soon as I want to keep these The Club posts short whenever possible. So, let me state just a few reasons (there are more) and then I’ll move on to my main topic for today. It’s more readable It’s more efficient (try timing the versions above using timeit —remove the print() calls first) It’s less prone to errors and bugs It works with a broader selection of data structures, not just sequences While you wait for my follow-up post on this, you can read more about Python’s Iterator Protocol, iterables, and iterators here: The Anatomy of a for Loop Iterable: Python’s Stepping Stones A One-Way Stream of Data • Iterators in Python But let’s move on. Let’s say you want to print out the names alongside each runner’s position. You’d like the following output: 1. Jonathan 2. Michael 3. Samantha 4. Jessica 5. Daniel “Aha!” I’m often told by some learners, “This is when you need to use the for i in range(len(funnel)) idiom, since you need the index!” Python’s for loop doesn’t explicitly use the index, so you don’t have access to the index within the for loop. Many revert to the non-Pythonic idioms for this. But Python provides tools that let you stay within the pure Pythonic style. Python’s for loop needs an iterator —it will create one from the iterable you provide. All Python iteration needs iterators, not just for loops. Iterators are Python’s tool for any iteration. And there are some bespoke iterators in Python that handle most of your iteration needs. I recently wrote a series about the itertools module. The itertools module contains many such tools. Here’s the series: The itertools Series . But there are also two built-in tools that many forget, but are extremely useful. The first one is enumerate() . Here’s how you can use it to display the Parkrun results: >>> for index, name in enumerate(funnel, start=1): ... print(f”{index}. {name}”) ... 1. Jonathan 2. Michael 3. Samantha 4. Jessica 5.

(" DEV ," " we ," or " us ") collects, use, and discloses your personal information. What's With the Defined Terms? You'll notice that some words appear in quotes in this Privacy Policy. They're called "defined terms," and we use them so that we don't have to repeat the same language again and again. They mean the same thing in every instance, to help us make sure that this Privacy Policy is consistent. We've included the defined terms throughout because we want it to be easy for you to read them in context. 1. WHAT DOES THIS PRIVACY POLICY APPLY TO? 2. PERSONAL INFORMATION WE COLLECT 3. HOW WE USE YOUR INFORMATION 4. HOW WE DISCLOSE YOUR INFORMATION 5. YOUR PRIVACY CHOICES AND RIGHTS 6. INTERNATIONAL DATA TRANSFERS 7. RETENTION OF PERSONAL INFORMATION 8. SUPPLEMENTAL DISCLOSURES FOR CALIFORNIA RESIDENTS 9. SUPPLEMENTAL NOTICE FOR NEVADA RESIDENTS 10. CHILDREN'S INFORMATION 11. OTHER PROVISIONS 12. CONTACT US 1. WHAT DOES THIS PRIVACY POLICY APPLY TO? This Privacy Policy applies to personal information processed by us, including on our websites, mobile applications, and other online or offline offerings — basically anything we do. To make this Privacy Policy easier to read, our websites, mobile applications, and other offerings are all collectively called the " Services. " Beyond this Privacy Policy, your use of the Services is subject to our DEV Community Terms and our Forem Terms. The Services include both our own community forum at https://www.dev.to (the " DEV Community ") and the open source tool we provide called " Forem ," available at https://www.forem.com which allows our customers to create and operate their own online forums. We collect personal information from two categories of people: (1) our customers, who use Forem and our hosting services to run and host their own forums (we'll call them " Forem Operators "), and (2) the people who interact with DEV-hosted forums, including forums provided by Forem Operators utilizing Forem and separately our own DEV Community (we'll call them " Users "). An Important Note for Users Since we provide hosting services for Forem Operators, technically we also process your information on their behalf. That processing is governed by the contracts that we have in place with each Forem Operator, not this Privacy Policy. In other words, when you share your data on a DEV-hosted forum operated by a Forem Operator, we at DEV are basically just the "pipes" — we process the data on behalf of the Forem Operator, but don't do anything with it ourselves beyond what we're required to do under our contract (and by law). So, if you post your information on a DEV-powered forum provided by a Forem Operator, that Forem Operator's privacy policy applies, and any questions or requests relating to your data on that service should be directed to that Forem Operator, not us. Likewise, if you use our mobile application, you may also interact with forums that use DEV's open-source tools but do all their hosting and data collection themselves. For those forums, we at DEV have no access to your data, so be sure to read the privacy policy of any third-party hosted forum before posting. 2. PERSONAL INFORMATION WE COLLECT The categories of personal information we collect depend on whether you're a User or Forem Operator, how you interact with us, our Services, and the requirements of applicable law. Breaking it down, we collect three types of information: (1) information that you provide to us directly, (2) information we obtain automatically when you use our Services, and (3) information we get about you from other sources (such as third-party services and organizations). More details are below. A. Information You Provide to Us Directly We may collect the following personal information that you provide to us. Account Creation (for Forem Operators): We'll require your name and email address to get started, as well as some details about the Forem you want to run, such as: whether you're running the Forem on your own behalf or as part of an organization, and details about the community you want to support (how big is it, what topics does it cover, where do members currently communicate, how/if the community earns money, whether the community is open, invite-only or paid, any existing social media accounts, etc.) You'll need to tell us a bit about your personal coding background, and you'll have the option to provide your DEV username as well, if you are a member of the DEV.to community. Account Creation (for Users) : We collect name and email address from users that create an account on DEV Community. For other forums created by Forem Operators using Forem, the Forem Operator determines what information is required for User account creation for their respective forums. Interactive Features (for Users) . Like any other social network, both we and other Users of our Services may collect personal information that you submit or make available through our interactive features (e.g., messaging and chat features, commenting functionalities, forums, blogs, posts, and other social media pages). While we do have private messages that are only between you and the person you're messaging (as well as us and the Forem Operator, as applicable), any information you provide using the public sharing features of the Services, such as the information you post to your public profile or the topics you follow is public, including to recruiters and prospective employers, and is not subject to any of the privacy protections we mention in this Privacy Policy except where legally required. Please exercise caution before revealing any information that may identify you in the real world to others. Purchases . If you buy stuff on our shop site https://shop.dev.to/ (as either a User or Forem Operator), or otherwise if you pay us in connection with your use of the Forem service, we may collect personal information and details associated with your purchases, including payment information.

Report Abuse Brian Treese Posted on Dec 5, 2025 • Originally published at briantree.se Signal Forms Just Got Automatic State Classes (And More) # javascript # angular # typescript # webdev Y ou know how in Reactive Forms , Angular automatically gave us state-based classes like ng-touched , ng-dirty , ng-pending , and ng-valid ? Well when Signal Forms launched, we lost all of that. But in a recent Angular update, this feature quietly came back. And not just back, now we can fully customize it. In this post, I'll show you how easy it is to turn these classes back on and how to go beyond what Reactive Forms ever allowed. Reactive Forms vs Signal Forms: Where Did ng-* Classes Go? Here we have a form built with reactive forms: When we interact with the form, the built-in "ng-" prefixed state-based classes are applied automatically for us: Alright, let’s look at the exact same app, but now converted over to Signal Forms: Visually, it looks the same, but when we trigger different states of this form, notice we no longer get any of those state-based classes: No ng-dirty , no ng-invalid , no ng-pending , nothing. And if your styling depended on these like our app does, this breaks things immediately after migration. Luckily, as of Angular 21.0.1 , there's now a really clean way to add them back. Let's Explore How This Signal Form Is Built Before we fix it though, let's quickly walk through how this form is actually wired, because the fix is going to feel almost too easy once you see it. Let's start with the styles for this component. You can see that we're still using the old "ng-" prefixed classes left over from Reactive Forms: input { // touched vs untouched & .ng-untouched { background-color : rgba ( white , 0 .05 ); } & .ng-touched { background-color : rgba ( #007bff , 0 .15 ); } // dirty vs pristine & .ng-dirty { box-shadow : 0 0 0 2px rgba ( #007bff , 0 .12 ); } // valid vs invalid & .ng-touched.ng-invalid { border-color : #e53935 ; } & .ng-touched.ng-valid { border-color : #43a047 ; } // pending & .ng-pending { border-color : orange ; } } Enter fullscreen mode Exit fullscreen mode So clearly, if we want this styling to work again with Signal Forms, we need some way to re-introduce those same state-based classes, or at least something equivalent. Now let's take a look at the component template . Signal Forms Template Walkthrough: The New [field] Directive Here's the username input, and instead of formControlName , we're using the new field directive from the Signal Forms API: <input id= "username" type= "text" [field]= "form.username" /> Enter fullscreen mode Exit fullscreen mode That binding connects this input directly to a Field object from our Signal Form. That Field gives us reactive access to everything: the value, touched, dirty, valid, and pending, All as signals. And then below this input, we have a little debug panel that simply shows that state in real time: touched, dirty, valid, and pending: @let username = form.username(); <h3> Field State </h3> <ul> <li [class.active]= "username.touched()" > touched: <strong> {{ username.touched() }} </strong> </li> <li [class.active]= "username.dirty()" > dirty: <strong> {{ username.dirty() }} </strong> </li> <li [class.active]= "username.valid()" > valid: <strong> {{ username.valid() }} </strong> </li> <li [class.active]= "username.pending()" > pending: <strong> {{ username.pending() }} </strong> </li> </ul> Enter fullscreen mode Exit fullscreen mode So technically, we could manually bind these as classes on the input using these state conditions, right? <input id= "username" type= "text" [field]= "form.username" [class.ng-untouched]= "!username.touched()" [class.ng-touched]= "username.touched()" [class.ng-dirty]= "username.dirty()" [class.ng-valid]= "username.valid()" [class.ng-pending]= "username.pending()" /> Enter fullscreen mode Exit fullscreen mode But that would be pretty painful to do on every control, so that's definitely not the solution we want. Now let's switch over to the component TypeScript . Signal Forms TypeScript Deep Dive: model and form() The first thing we have here is this "model" signal : interface SignUpForm { username : string ; } protected model = signal < SignUpForm > ({ username : '' , }); Enter fullscreen mode Exit fullscreen mode This is the source of truth for our form's data. It replaces the old FormGroup value object. Instead of mutating controls directly, Signal Forms now updates this signal automatically. Next, we have the form() function: import { ..., form } from ' @angular/forms/signals ' ; protected form = form ( this . model , s => { ... }); Enter fullscreen mode Exit fullscreen mode This connects the model to the actual form behavior. With this function, we pass it the model signal, followed by a schema callback where we can add validation. Here, s.username represents the username as a field builder. We use this to add required() , minLength() , debounce() , and the async validator ( validateAsync() ) to check if the name already exists: import { ..., required , minLength , debounce , validateAsync } from ' @angular/forms/signals ' ; protected form = form ( this . model , s => { required ( s . username , { message : ' A username is required ' }); minLength ( s . username , 3 , { message : ' Username must be at least 3 characters ' , }); debounce ( s . username , 500 ); validateAsync ( s . username , { ... }); }); Enter fullscreen mode Exit fullscreen mode So conceptually, everything we had in our Reactive Form setup still exists here. It’s just driven by signals instead of observables. New in Angular 21.0.1: Global Signal Forms Configuration Now here's what the Angular team has quietly fixed for us. Signal Forms now has a new application-level configuration API that allows it to inject CSS classes based on field state, just like Reactive Forms used to. And the best part? You only have to set this up once for your entire app. To add this, we need to make a small change in our main application configuration. In this app, that lives in main.ts , where the Angular application is bootstrapped. In the providers array, we need to add a new method called provideSignalFormsConfig() : import { provideSignalFormsConfig } from ' @angular/forms/signals ' ; import { NG_STATUS_CLASSES } from ' @angular/forms/signals/compat ' ; bootstrapApplication ( AppComponent , { providers : [ ..., provideSignalFormsConfig ({ classes : NG_STATUS_CLASSES }) ] }); Enter fullscreen mode Exit fullscreen mode This lets us define how Signal Forms behaves globally across the entire app. Inside this config object, we've added a new classes property, and for its value we're using the built-in NG_STATUS_CLASSES constant. This one constant automatically recreates the classic "ng-" class behavior from Reactive Forms. And that's it! That's literally all we need to add. And then, once we save... There they are! Now as we interact with this field, we're right back to the familiar "ng-" prefixed classes: ng-touched , ng-dirty , ng-pending , and ng-valid . We're officially back in business. Custom State Classes in Signal Forms (Beyond ng-*) Now here's the really interesting part, and this is something we never had in Reactive Forms. What if you don't want ng-invalid ? What if you want app-invalid or danger-zone or yikes-that-input-is-wrong ? With Signal Forms, we can now do this globally and cleanly. Instead of using the built-in constant, we just replace it with our own object: provideSignalFormsConfig ({ classes : { ..., ' app-touched ' : s => s . touched (), ' app-untouched ' : s => ! s . touched (), ' app-dirty ' : s => s . dirty (), ' app-pristine ' : s => ! s . dirty (), ' app-valid ' : s => s . valid (), ' app-invalid ' : s => s . invalid (), ' app-pending ' : s => s . pending () } }) Enter fullscreen mode Exit fullscreen mode Each key is the class name as a string, and each value is a function that returns whether that class should be applied based on live field state. Now we just need to update our class selectors in the CSS to match: input { // touched vs untouched & .app-untouched { ... } & .app-touched { ... } // dirty vs pristine & .app-dirty { ... } // valid vs invalid & .app-touched.app-invalid { ... } & .app-touched.app-valid { ... } // pending & .app-pending { ... } } Enter fullscreen mode Exit fullscreen mode And that should be it. Final Result: Fully Branded Automatic Form State Styling After we save, this is what we get: Nice, now instead of "ng-" classes we've got "app-" prefixed classes instead. Same automatic behavior, fully branded, zero template bindings. Conditional State Classes for Better UX Here's where this gets even cooler at a global level. Let's say we don't want our invalid class to show up immediately. Let's say we only want it to apply when the field is both invalid and touched. That's now trivial to do, we just add that condition directly into our custom class config: provideSignalFormsConfig ({ classes : { ..., ' app-invalid ' : s => s . invalid () && s . touched (), } }) Enter fullscreen mode Exit fullscreen mode So instead of just checking invalid , now this app-invalid class only applies when the field is invalid and touched. And just like that, we've moved real UX logic into a single, centralized config. Pretty powerful, right? Why This Update Changes Signal Forms for Good This is one of those small Angular updates that quietly fixes a real pain point, and actually gives us more power than we had before. We now get: automatic state classes global configuration and full customization All without adding noise to our templates. If you're already using Signal Forms for validation, async checks, or dynamic forms, this is one of those upgrades you absolutely want turned on!

Report Abuse Ishika-jain Posted on Jan 12 How to ask awesome questions as a dev (Without Dying of Imposter Syndrome) # productivity # mentalhealth # beginners I have been there. Trust me, I have . In concrete jungles. With beasts in suits. (Okay fine, hoodies. Always hoodies.) I hated asking questions - admitting there were things I didn’t know was my worst nightmare when I first joined. So I know how hard it is. Especially when everyone around you looks like they popped out of the womb knowing Docker, Git, and the difference between == and === . So here’s a guide on how to ask awesome questions. Whether you’re just starting out or you’ve been in the game for a while, one thing is inevitable: you will not understand certain things . You will get stuck. And the longer you keep those questions trapped in your head, the bigger your imposter-syndrome monster grows. It starts whispering things like: “Everyone else gets this.” “You’re just dumb and don’t deserve to be here” “If you ask, they’ll know you’re a fraud.” “Just stare at the bug harder. It’ll fix itself.” (It won’t.) “So how do you get your questions answered?” you ask. “You just ask them,” I say. DUH. But how you ask matters. What Is a Good Question? Before we talk about how to ask good questions, let’s define what a good question actually is. A good question is… a question. Yup. That’s it. Any question you genuinely have is a good question— as long as it’s asked out of curiosity and effort , not laziness. Good questions: Help you get better answers, faster Show that you care about understanding, not just un-blocking yourself Build credibility over time Strengthen your problem-solving muscles Bad questions aren’t the ones that sound “basic.” Bad questions are the ones where zero effort happened before asking. Do Your Homework (Yes, This Is Mandatory) Before asking a question, do a quick reality check: Have you: Googled it? Checked Stack Overflow? Read the documentation (at least skimmed it)? Tried debugging on your own? Searched if this exact question has already been asked? In other words: ask the question to yourself first and see how much information you can gather. You don’t need to solve it completely. You just need to try. Effort is obvious. And effort is respected. How to Structure Your Question (So People Actually Want to Help) 1. Provide Context Start with what you’re trying to do , not just what’s broken. People can’t help if they don’t understand the bigger picture. Instead of saying “This just doesn’t work” try “I’m trying to fetch user data after login and render it in a table.” 2. Show What You’ve Tried Nothing earns goodwill faster than saying “Here’s what I’ve already tried.” List your attempts and what happened. Even if they were wrong. Especially if they were wrong. 3. Include Relevant Details (Not Your Life Story) Include: Your environment (OS, language version, framework version) Exact error messages (copy-paste them) Minimal code that reproduces the issue What you expected to happen vs. what actually happened Exclude: Your entire codebase 400-line files Unwillingness to learn 4. Be Specific Instead of “My code doesn’t work., try something like “My React component throws Cannot read property 'map' of undefined when I try to render API data before the request completes.” Specific questions get specific answers. 5. Make It Easy to Help You You are not just asking for help—you are collaborating . So: Format your code properly Keep examples minimal Remove distractions If helping you feels like homework, people will quietly back away. Question Templates (Steal These) Debugging Help I’m trying to [goal], but [what’s happening instead]. Here’s my code: [minimal example] Error message: [exact error] I’ve tried: [list attempts] Environment: [relevant versions] Conceptual Questions I’m learning about [topic] and trying to understand [specific concept]. From what I understand so far: [your current understanding] . What I’m confused about: [specific gap] . Context: [why this matters to you] . Best Practices / Design Decisions I need to [accomplish task]. I’m considering [approach A] vs [approach B] . My constraints are: [limitations] . What are the tradeoffs here? What NOT to Do (Please) “Can I ask a question?” — just ask it “This is probably a dumb question” — don’t undermine yourself Expecting others to debug your entire codebase Asking five unrelated questions in one message Vanishing after you get help After You Get an Answer Do these things. They matter more than you think: Say thank you Share what worked If you solved it later, post the solution Pay it forward when you can Today’s confused developer is tomorrow’s senior engineer answering questions on Teams at 11 PM. Remember Everyone was a beginner once. Asking questions doesn’t make you less capable—it makes you a (better) learner. The best developers don’t magically know everything. They just got really, really good at asking great questions. And now, so can you.

Report Abuse Ava Mendes Posted on Dec 19, 2025 Smart Meters em Condomínios: Impactos Legais e Técnicos na Portabilidade até 2027 # energy # smarthomes # iot # smartcities Smart Meters em Condomínios: Impactos Legais e Técnicos na Portabilidade até 2027 Você mora em um condomínio e recebe uma conta de luz cada vez mais cara? A boa notícia é que uma revolução silenciosa está acontecendo nas redes elétricas brasileiras — e pode afetar significativamente quanto você paga pela energia. Os medidores inteligentes (smart meters) estão chegando aos condomínios brasileiros em ritmo acelerado. Mas o que isso significa na prática? Como afeta a portabilidade da conta de luz? E, mais importante: quanto você pode economizar? Neste artigo, você vai descobrir como essa tecnologia funciona, que impactos legais e técnicos ela traz para condomínios, e como se preparar para as mudanças que virão até 2027. O que são Smart Meters e por que estão chegando agora? Um medidor inteligente não é apenas um aparelhinho que mede seu consumo. É um dispositivo conectado que se comunica constantemente com a distribuidora de energia, enviando dados de consumo em intervalos muito curtos — geralmente a cada 15 minutos. Diferente dos medidores convencionais, que exigem leitura manual mensal, os smart meters funcionam assim: Leitura remota automática : A distribuidora não precisa enviar um leitor até sua casa Dados granulares : Você sabe exatamente quanto consumiu em cada período do dia Comunicação bidirecional : A distribuidora pode se comunicar com o medidor e até desligar remotamente em caso de inadimplência Detecção de anomalias : O sistema identifica rápido quando há vazamentos de energia ou fraudes Por que agora? O Brasil tem cerca de 90 milhões de consumidores de energia, e apenas 4 milhões possuem medidores inteligentes instalados (dados de 2024). O Ministério de Minas e Energia abriu em 2025 uma consulta pública estabelecendo metas: cada distribuidora deve instalar smart meters em pelo menos 4% de suas unidades consumidoras em 12 meses. Grandes distribuidoras já estão nessa corrida. A Copel, no Paraná, instalou 1,7 milhão de unidades. A Cemig substituiu mais de 2 milhões desde 2021. A CPFL investirá R$ 1,2 bilhão para trocar 1,6 milhão de medidores até 2029. Como Smart Meters Funcionam em Condomínios Em um condomínio, a situação é um pouco diferente de uma casa isolada. Existem dois cenários principais: Medição Coletiva Ainda é o modelo mais comum. Um único medidor registra todo o consumo do condomínio (áreas comuns + todas as unidades), e a conta é dividida entre os moradores — geralmente por rateio igual ou proporcional à metragem. Problema? Quem usa pouca energia subsidia quem usa muita. Não há incentivo individual para economizar. Medição Individualizada com Smart Meters Cada unidade tem seu próprio medidor inteligente. A distribuidora mede o consumo de forma independente, e cada morador paga apenas pelo que consome. Vantagem? Justiça tarifária total. Se você desligar a luz, a economia aparece na sua conta, não na do vizinho. A medição individualizada com smart meters é tecnicamente viável e está crescendo em condomínios novos e em reformas. Mas exige uma estrutura elétrica adequada e, claro, vontade do condomínio em modernizar. Impactos Legais: O que Muda até 2027? Aqui está a questão que mais interessa: medidores inteligentes são obrigatórios para portabilidade da conta até 2027? A resposta é: ainda não há regra específica que torne isso obrigatório , mas a tecnologia é considerada pré-requisito técnico para modelos avançados de escolha de fornecedor. A Portaria MME nº 111/2025 Em 2025, o Ministério de Minas e Energia publicou diretrizes para digitalização das redes de distribuição. Essa portaria estabelece 13 diretrizes, incluindo: Inovação em serviços (tarifas dinâmicas, resposta à demanda) Transparência de dados de consumo Resiliência a eventos climáticos extremos Avaliação de desempenho das distribuidoras O que isso significa? Smart meters são a base técnica para que o Brasil consiga oferecer serviços mais avançados e, eventualmente, abrir o mercado livre para residências e pequenos comércios. Abertura do Mercado Livre em 2026-2027 A CCEE (Câmara de Comercialização de Energia Elétrica) tem discutido a abertura do mercado livre para consumidores de baixa tensão. Quando isso acontecer, famílias e pequenos comércios poderão escolher seu fornecedor de energia — assim como já fazem as grandes empresas. Requisito técnico? Medição precisa e transparente. Os smart meters facilitam enormemente isso, pois permitem comparações reais de consumo entre fornecedores. Impactos Técnicos: Como Muda a Operação do Condomínio? Eliminação da Leitura Manual Hoje, um leitor da distribuidora passa mensalmente no condomínio para anotar o consumo. Com smart meters, isso desaparece. Mais prático? Sim. Menos burocracia? Com certeza. Acesso a Dados Detalhados via App Distribuidoras como Copel já oferecem aplicativos onde você acompanha seu consumo em intervalos de 15 minutos. Isso permite identificar: Qual eletrodoméstico consome mais Em que horários o consumo é maior Padrões de desperdício Possibilidade de Tarifas Horárias Com dados granulares, a distribuidora pode oferecer tarifas diferenciadas por horário — mais cara no pico (18h-21h), mais barata fora do pico. Para famílias de alto consumo em condomínios, isso abre oportunidade: deslocar cargas (máquina de lavar, aquecedor) para fora do pico pode gerar economia real. Integração com Automação Smart meters se comunicam com sistemas de automação residencial. Você pode programar que o ar-condicionado ligue apenas fora do horário de pico, por exemplo. Economia Real: Quanto Você Pode Poupar? Aqui está a verdade: o medidor inteligente, por si só, não reduz sua conta de luz . Ele apenas fornece informações. A economia vem de ações que você toma com base nesses dados . Cenário 1: Família de Alto Consumo (R$ 600/mês) Com dados detalhados, essa família identifica que o ar-condicionado consome 40% da energia. Ao usá-lo apenas fora do pico (22h-6h), reduz o consumo em 25%. Economia: R$ 150/mês = R$ 1.800/ano Cenário 2: Portabilidade para Fornecedor do Mercado Livre Quando a abertura acontecer, famílias podem migrar para fornecedores com preço mais competitivo — como a energialex.app , que oferece energia 100% renovável com economia de até 20% para consumidores do Grupo B (residências e pequenos comércios). Economia: 20% na tarifa = R$ 120/mês em uma conta de R$ 600 Combine os dois cenários e você chega a R$ 270/mês de economia . Privacidade e Proteção de Dados em Condomínios Uma preocupação legítima: dados granulares de consumo revelam padrões de vida . Se o medidor registra que você liga o ar-condicionado às 14h todo dia de semana, isso pode revelar que você trabalha em casa. Se o consumo sobe drasticamente em certos dias, pode indicar festas ou visitas. Como se proteger? Conformidade com LGPD : O condomínio deve ter política clara de acesso e retenção de dados Anonimização : Relatórios gerenciais não devem identificar unidades específicas Controle de acesso : Apenas síndico e administradora devem ver dados individuais Transparência : Informar moradores sobre coleta e uso de dados Distribuidoras e plataformas como energialex.app já operam com conformidade à LGPD, armazenando dados de forma segura e permitindo que você controle o acesso. Checklist: Como Preparar seu Condomínio para Smart Meters Se você é síndico ou mora em condomínio e quer se preparar para essa transição: ☑ Passo 1: Mapeie a Situação Atual Qual tipo de medição tem seu condomínio (coletiva ou individualizada)? Os medidores são convencionais ou já há alguns inteligentes? Quando foi a última revisão do quadro elétrico? ☑ Passo 2: Consulte a Distribuidora Seu condomínio está em algum programa de substituição? Qual é o prazo estimado? Haverá custo para o condomínio? ☑ Passo 3: Avalie Benefícios Potenciais Quanto seu condomínio poderia economizar com medição individualizada? Há interesse dos moradores em automação residencial? ☑ Passo 4: Prepare a Governança de Dados Defina quem acessa relatórios de consumo Crie política de privacidade conforme LGPD Comunique aos moradores ☑ Passo 5: Acompanhe Regulamentação Fique atento a mudanças na ANEEL e CCEE Quando a abertura do mercado livre chegar, seu condomínio estará pronto FAQ: Dúvidas Frequentes sobre Smart Meters em Condomínios P: Medidores inteligentes aumentam ou diminuem a conta? R: Não aumentam automaticamente. Diminuem apenas se você usar os dados para reduzir consumo ou migrar para fornecedor mais barato. P: Quem paga pela instalação? R: Na maioria dos casos, a distribuidora investe e recupera via tarifa. Não há custo direto para o condomínio ou morador. P: Posso recusar o smart meter? R: Não. É decisão da distribuidora, não do consumidor. Mas o processo é simples e sem obras. P: Quando meu condomínio terá smart meter? R: Depende da distribuidora e região. Metas atuais são 4% das unidades em 12 meses. Você pode consultar sua distribuidora. Conclusão: O Futuro já Começou Os smart meters não são ficção científica. Estão chegando aos condomínios brasileiros agora. Até 2027, a expectativa é que milhões de unidades tenham essa tecnologia, criando base para abertura do mercado livre e novos modelos de tarifação. Para você, morador de condomínio, isso significa: ✅ Mais transparência no consumo de energia ✅ Oportunidade de economizar através de gestão inteligente ✅ Possibilidade de escolher fornecedor quando o mercado abrir ✅ Maior segurança contra fraudes e perdas técnicas Quer ir além? Quando a portabilidade da conta for possível, plataformas como energialex.app tornam o processo simples, 100% online e gratuito. Você pode simular sua economia em menos de 2 minutos — sem compromisso, sem burocracia, sem custos. O futuro da energia é digital, inteligente e mais justo. E você pode começar a se preparar hoje.

The only way to get out of this, is by converting every single account to be a billing account not placed in an Organization. It's an unfortunate change that I wished AWS didn't make.

(" DEV ," " we ," or " us ") collects, use, and discloses your personal information. What's With the Defined Terms? You'll notice that some words appear in quotes in this Privacy Policy. They're called "defined terms," and we use them so that we don't have to repeat the same language again and again. They mean the same thing in every instance, to help us make sure that this Privacy Policy is consistent. We've included the defined terms throughout because we want it to be easy for you to read them in context. 1. WHAT DOES THIS PRIVACY POLICY APPLY TO? 2. PERSONAL INFORMATION WE COLLECT 3. HOW WE USE YOUR INFORMATION 4. HOW WE DISCLOSE YOUR INFORMATION 5. YOUR PRIVACY CHOICES AND RIGHTS 6. INTERNATIONAL DATA TRANSFERS 7. RETENTION OF PERSONAL INFORMATION 8. SUPPLEMENTAL DISCLOSURES FOR CALIFORNIA RESIDENTS 9. SUPPLEMENTAL NOTICE FOR NEVADA RESIDENTS 10. CHILDREN'S INFORMATION 11. OTHER PROVISIONS 12. CONTACT US 1. WHAT DOES THIS PRIVACY POLICY APPLY TO? This Privacy Policy applies to personal information processed by us, including on our websites, mobile applications, and other online or offline offerings — basically anything we do. To make this Privacy Policy easier to read, our websites, mobile applications, and other offerings are all collectively called the " Services. " Beyond this Privacy Policy, your use of the Services is subject to our DEV Community Terms and our Forem Terms. The Services include both our own community forum at https://www.dev.to (the " DEV Community ") and the open source tool we provide called " Forem ," available at https://www.forem.com which allows our customers to create and operate their own online forums. We collect personal information from two categories of people: (1) our customers, who use Forem and our hosting services to run and host their own forums (we'll call them " Forem Operators "), and (2) the people who interact with DEV-hosted forums, including forums provided by Forem Operators utilizing Forem and separately our own DEV Community (we'll call them " Users "). An Important Note for Users Since we provide hosting services for Forem Operators, technically we also process your information on their behalf. That processing is governed by the contracts that we have in place with each Forem Operator, not this Privacy Policy. In other words, when you share your data on a DEV-hosted forum operated by a Forem Operator, we at DEV are basically just the "pipes" — we process the data on behalf of the Forem Operator, but don't do anything with it ourselves beyond what we're required to do under our contract (and by law). So, if you post your information on a DEV-powered forum provided by a Forem Operator, that Forem Operator's privacy policy applies, and any questions or requests relating to your data on that service should be directed to that Forem Operator, not us. Likewise, if you use our mobile application, you may also interact with forums that use DEV's open-source tools but do all their hosting and data collection themselves. For those forums, we at DEV have no access to your data, so be sure to read the privacy policy of any third-party hosted forum before posting. 2. PERSONAL INFORMATION WE COLLECT The categories of personal information we collect depend on whether you're a User or Forem Operator, how you interact with us, our Services, and the requirements of applicable law. Breaking it down, we collect three types of information: (1) information that you provide to us directly, (2) information we obtain automatically when you use our Services, and (3) information we get about you from other sources (such as third-party services and organizations). More details are below. A. Information You Provide to Us Directly We may collect the following personal information that you provide to us. Account Creation (for Forem Operators): We'll require your name and email address to get started, as well as some details about the Forem you want to run, such as: whether you're running the Forem on your own behalf or as part of an organization, and details about the community you want to support (how big is it, what topics does it cover, where do members currently communicate, how/if the community earns money, whether the community is open, invite-only or paid, any existing social media accounts, etc.) You'll need to tell us a bit about your personal coding background, and you'll have the option to provide your DEV username as well, if you are a member of the DEV.to community. Account Creation (for Users) : We collect name and email address from users that create an account on DEV Community. For other forums created by Forem Operators using Forem, the Forem Operator determines what information is required for User account creation for their respective forums. Interactive Features (for Users) . Like any other social network, both we and other Users of our Services may collect personal information that you submit or make available through our interactive features (e.g., messaging and chat features, commenting functionalities, forums, blogs, posts, and other social media pages). While we do have private messages that are only between you and the person you're messaging (as well as us and the Forem Operator, as applicable), any information you provide using the public sharing features of the Services, such as the information you post to your public profile or the topics you follow is public, including to recruiters and prospective employers, and is not subject to any of the privacy protections we mention in this Privacy Policy except where legally required. Please exercise caution before revealing any information that may identify you in the real world to others. Purchases . If you buy stuff on our shop site https://shop.dev.to/ (as either a User or Forem Operator), or otherwise if you pay us in connection with your use of the Forem service, we may collect personal information and details associated with your purchases, including payment information. Any payments made via our Services are processed by third-party payment processors, such as Stripe, Shopify, and PayPal. We do not directly collect or store any payment card information entered through our Services, but may receive information associated with your payment card information (e.g., your billing details). Your Communications with Us (Users and Forem Operators) . We may collect personal information, such as email address, phone number, or mailing address when you request information about our Services, register for our newsletter or loyalty program, request customer or technical support, apply for a job, or otherwise communicate with us. Surveys . We may contact you to participate in surveys. If you decide to participate, you may be asked to provide certain information, which may include personal information (for example, your home address). Sweepstakes or Contests . We may collect personal information you provide for any sweepstakes or contests that we offer. In some jurisdictions, we are required to publicly share information of sweepstakes and contest winners. Conferences, Trade Shows, and Other Events . We may collect personal information from individuals when we attend conferences, trade shows, and other events. Business Development and Strategic Partnerships . We may collect personal information from individuals and third parties to assess and pursue potential business opportunities. Job Applications . We may post job openings and opportunities on our Services. If you reply to one of these postings by submitting your application, CV and/or cover letter to us, we will collect and use your information to assess your qualifications. B. Information Collected Automatically We may collect personal information automatically when you use our Services: Automatic Data Collection . We may collect certain information automatically when you use our Services, such as your Internet protocol (IP) address, user settings, MAC address, cookie identifiers, mobile carrier, mobile advertising and other unique identifiers, browser or device information, location information (including approximate location derived from IP address), and Internet service provider. We may also automatically collect information regarding your use of our Services, such as pages that you visit before, during and after using our Services, information about the links you click, the types of content you interact with, the frequency and duration of your activities, and other information about how you use our Services. In addition, we may collect information that other people provide about you when they use our Services, including information about you when they tag you in their posts. Cookies, Pixel Tags/Web Beacons, and Other Technologies . We, as well as third parties that provide content, advertising, or other functionality on our Services, may use cookies, pixel tags, local storage, and other technologies (" Technologies ") to automatically collect information through your use of our Services. Cookies . Cookies are small text files placed in device browsers that store preferences and facilitate and enhance your experience. Pixel Tags/Web Beacons . A pixel tag (also known as a web beacon) is a piece of code embedded in our Services that collects information about engagement on our Services. The use of a pixel tag allows us to record, for example, that a user has visited a particular web page or clicked on a particular advertisement. We may also include web beacons in e-mails to understand whether messages have been opened, acted on, or forwarded. Our uses of these Technologies fall into the following general categories: Operationally Necessary . This includes Technologies that allow you access to our Services, applications, and tools that are required to identify irregular website behavior, prevent fraudulent activity and improve security or that allow you to make use of our functionality. Performance-Related . We may use Technologies to assess the performance of our Services, including as part of our analytic practices to help us understand how individuals use our Services ( see Analytics below ). Functionality-Related . We may use Technologies that allow us to offer you enhanced functionality when accessing or using our Services. This may include identifying you when you sign into our Services or keeping track of your specified preferences, interests, or past items viewed. Analytics . We may use Technologies and other third-party tools to process analytics information on our Services. Some of our analytics partners include Google Analytics. For more information,please visit Google Analytics' Privacy Policy . To learn more about how to opt-out of Google Analytics' use of your information, please click here . Social Media Platforms . Our Services may contain social media buttons such as Twitter, Facebook, GitHub, Instagram, and Twitch (that might include widgets such as the "share this" button or other interactive mini programs). These features may collect your IP address, which page you are visiting on our Services, and may set a cookie to enable the feature to function properly. Your interactions with these platforms are governed by the privacy policy of the company providing it. See the "Your Privacy Choices and Rights" section below to understand your choices regarding these Technologies. C. Information Collected from Other Sources We may obtain information about you from other sources, including through third-party services and organizations. For example, if you access our Services through a third-party application, such as an app store, a third-party login service (e.g., through Twitter, Apple, or GitHub), or a social networking site, we may collect whatever information about you from that third-party application that you have made available via your privacy settings. 3.

(The referred party may also receive rewards for signing up via your referral.) These programs are entirely voluntary and allow us to grow our business and provide additional benefits to you. The value of your data to us depends on how you ultimately use our Services, whereas the value of the referred party's data to us depends on whether the referred party ultimately becomes a User or Forem Operator and uses our Services.

Report Abuse Fabian Frank Werner Posted on Dec 27, 2025 JavaScript vs TypeScript - I built the same crypto tracker with both # javascript # typescript # beginners # webdev If you are building a web application today, there are two heavyweights competing for your attention. In the red corner, we have JavaScript —the king of the web; and in the blue corner, we have TypeScript —the challenger from Microsoft. Both tools achieve the same fundamental goal: they make things happen in a browser. But there is a world of difference in the developer experience. No matter which one you choose, the other one automatically becomes your arch-nemesis. Because you don’t choose anything but the absolute best technology out there. To figure out which one is best, I built the exact same Real-Time Crypto Tracker with both JavaScript and TypeScript. In this post, we are going to dive into a detailed side-by-side comparison of the features, tooling, ecosystem, performance, and of course, the code! By the end of this post, you will know exactly which one fits best in your ideology. But this isn't a line-by-line coding tutorial. If you want to learn how to build these apps from scratch, subscribe to my free newsletter . Let’s start by comparing the setup and the "Barrier to Entry." Setup To get started, we are using Vite. Why Vite? Because create-react-app is dead, and we don't mourn the dead here; we move on to faster tools. For JavaScript, I run npm create vite@latest crypto-tracker-js -- --template react . For TypeScript, it’s npm create vite@latest crypto-tracker-ts -- --template react-ts . Both are blazingly fast. Vite doesn't care about your feelings or your language preference; it just scaffolds the project instantly. But as soon as we open the projects in VS Code, the difference slaps you in the face. In the JavaScript project, you have your package.json , your vite.config.js , and your source files ending in .jsx . It feels lightweight. You can almost hear the wind whistling through the empty space where configuration files usually live. It invites you to just start coding. Now, look at the TypeScript project. You see .tsx files, which is fine, but then you see tsconfig.json and tsconfig.node.json . This file is the constitution of your project. It dictates the laws of your universe. In JavaScript, the laws are "whatever works." In TypeScript, you have to explicitly tell the compiler how strict you want to be. Do you want to allow implicit any types? Do you want to check for unused local variables? Do you want to strictly check for nulls? For a beginner, this file is a wall of JSON that screams "Configuration Hell." You have to understand what a "target" is and how module resolution works before you even write "Hello World." For a senior engineer, however, this file is a safety blanket. It guarantees that every developer on the team is playing by the same rules. Structure The core difference between these two isn't just syntax; it's when you catch your mistakes. JavaScript is dynamically typed, which means variables can be anything at any time. TypeScript is statically typed, meaning once a variable is a number, it dies a number. Let's look at the Coin component. We are fetching a list of crypto coins from an API. const CoinRow = ({ coin }) => { return ( < div className = "row" > < img src = { coin . image } /> < span > { coin . name } </ span > < span > $ { coin . current_price } </ span > </ div > ); }; Enter fullscreen mode Exit fullscreen mode In JavaScript , I write a component that takes a prop called data . This looks innocent. But as I'm typing coin.current_price , I am relying entirely on my own memory. I have to keep the API documentation open on a second monitor. Is it current_price or currentPrice ? Is image a string URL or an object containing sizes? If I type coin.price instead of coin.current_price , the editor doesn't care. It saves the file. I run the app. The browser renders an empty span. I spend 15 minutes console logging coin to figure out why the price is missing. This is the "Guess and Check" loop, and it burns hours of your life. export interface Coin { id : string ; symbol : string ; name : string ; image : string ; current_price : number ; high_24h : number ; low_24h : number ; } Enter fullscreen mode Exit fullscreen mode Now, watch the TypeScript workflow. Before I even think about the UI, I have to define the shape of my data. This is mental overhead. I have to stop, look at the API response, and translate it into an Interface. import type { Coin } from ' ./types ' ; interface Props { coin : Coin ; } const CoinRow = ({ coin }: Props ) => { return ( < div className = "row" > { /* The moment I type "coin.", a dropdown appears */ } < span > { coin . current_price } </ span > </ div > ); }; Enter fullscreen mode Exit fullscreen mode The editor knows what a coin is. If I try to access coin.price , the text turns red immediately. "Property 'price' does not exist on type 'Coin'." This is the killer feature. I am not coding in the dark anymore. The IDE is my pair programmer, constantly whispering the correct property names in my ear. It turns the documentation into code that lives right under your cursor. Data export const fetchCoins = async () => { const res = await fetch ( ' https://api.coingecko.com/... ' ); return res . json (); }; Enter fullscreen mode Exit fullscreen mode Let's dial up the complexity. We need to fetch this data from the internet. This introduces asynchronous code and the concept of "Generics." In JavaScript , our fetch function is simple, but dangerous. The return value of this function is a Promise that resolves to... any . It could be an object, an array, a string, or an error message. We don't know, and JavaScript doesn't care. When we consume this function in our React component, we are flying blind. export const fetchData = async < T > ( url : string ): Promise < T > => { const res = await fetch ( url ); if ( ! res . ok ) { throw new Error ( ' Network response was not ok ' ); } const data = await res . json (); return data as T ; }; Enter fullscreen mode Exit fullscreen mode In TypeScript , we want to tell the consumer of this function exactly what they are getting back. This is where we use Generics . This generic <T> allows us to use this one fetch function for Coins, for User profiles, for anything, while maintaining strict typing. However, there is a dirty secret here. Look at return data as T . That as keyword is a lie. We are lying to the compiler. We are saying, "I promise this JSON from the internet matches my Interface." But what if the API changes? What if the internet goes down? TypeScript checks your code at compile time , not runtime . If the API sends back a price as a string instead of a number, TypeScript won't catch it, and your app might still crash. To truly fix this, you would need a runtime validation library like Zod . With Zod, you define a schema that validates the data as it comes in , effectively bridging the gap between the static world of TypeScript and the chaotic world of runtime JavaScript. But that adds bundle size and complexity, which is the constant trade-off you make in this ecosystem. Trap Now let’s look at how we store this data in React state. const [ coins , setCoins ] = useState ([]); Enter fullscreen mode Exit fullscreen mode In JavaScript , it’s simple. coins is an array. I can push numbers into it, strings, objects, or even null . const [ coins , setCoins ] = useState < Coin [] > ([]); Enter fullscreen mode Exit fullscreen mode In TypeScript , inference usually works well, but sometimes we need to be explicit: Now, if I try to setCoins(['bitcoin']) , TypeScript yells at me because a string is not a Coin object. This prevents state contamination, where you accidentally store the wrong data type and break your app five steps down the line. But here is where developers get lazy. Sometimes, TypeScript is screaming at you because your types are complex. You just want it to shut up so you can test your feature. So you do the forbidden thing. const [ data , setData ] = useState < any > ([]); Enter fullscreen mode Exit fullscreen mode The any type essentially turns off TypeScript for that specific variable. It is a trap. Once you use any , it spreads like a virus. If you pass that any variable to another function, that function now accepts anything. You have successfully defeated the entire purpose of using TypeScript in the first place. Using any is like wearing a seatbelt made of paper. It looks like safety, but it won't save you when you crash. Refactoring If there is one reason to switch to TypeScript, it is this: Refactoring. Let's say our project manager decides that image is a bad name for the property. We need to rename it to imageUrl across the entire application. In the JavaScript project, this is a nightmare scenario. I have to use "Find and Replace." I search for "image". The search results include: The actual property in the API response. A CSS class named .coin-image . A comment in the README. A variable in a totally unrelated file. I have to manually check every single instance. If I miss one, the image breaks. If I change the wrong one, the CSS breaks. It is anxiety-inducing. In TypeScript , I go to my Interface. I put my cursor on image . I press F2 to Rename. I type imageUrl and hit Enter. VS Code analyzes the dependency graph. It knows exactly which references refer to this specific property on the Coin interface. It ignores the CSS classes. It ignores the comments. It updates the API call, the Prop types, and the Component usage in one second. I save the file, and I have 100% confidence that I didn't break anything. This feeling of safety allows you to iterate faster. You aren't afraid to change your code because the compiler has your back. Performance Finally, let’s talk about performance. There is a misconception that TypeScript is slower because it has to compile. Here is the reality: Browsers cannot run TypeScript. They only understand JavaScript. This means your TypeScript code must be erased before it ever reaches the user. Vite handles this using esbuild . It’s incredibly fast because during development, it doesn't actually check your types. It just strips them out so the browser can run the code. This means your dev server starts almost as fast as a plain JS project. However, for the production build, we run tsc (the TypeScript Compiler). This checks every single line of code for type errors. If there is a single error, the build fails. This is a feature, not a bug. It prevents you from shipping broken code to production. In JavaScript, that error would have made it to the user's browser and crashed their session. In TypeScript, it crashes your build server, forcing you to fix it. So, does TypeScript make your app faster? No. The runtime performance is identical. But does it make your development cycle faster? Over the long run, absolutely. Verdict So, after building this tracker twice, here is the verdict. JavaScript is the wild, fun friend who invites you to a rave at 2 AM. It’s great for hackathons, small prototypes, and solo projects where you just want to move fast and break things. It feels fluid, unrestricted, and creative. If I have an idea I want to validate in an afternoon, I might still reach for JavaScript. TypeScript , however, is the responsible architect. It demands a blueprint before you lay the first brick. At first, it feels restrictive. You spend time writing Interfaces instead of features. You fight with the configuration. You curse the compiler. But as the project grows—as you add more files, more complex data structures, and more team members—TypeScript becomes the only thing keeping your sanity intact. The ability to refactor instantly, the elimination of entire classes of bugs, and the self-documenting nature of the code make it the superior choice for any serious application. If you are looking to get hired in the industry today, TypeScript is not optional . It has won the war for attention. So, stick with JavaScript if you want to feel like a cowboy.

I mostly disagree. You are certainly quoting the company line that TS is better because it's more rigid. And compile time type checks have their place in large complex systems (but each large complex system should be broken down into simpler ones, no?) 30yr veteran here. I favor flexibility - so I favor JS. I favor conciseness so I favor JS. If you favor TS that's fine. But it makes it harder to collaborate. TS works great for simple examples. It becomes cumbersome & verbose for complex ones. Some things about your article that raised an eyebrow... I can press F2 & rename my JS variable just fine in VS Code (because the IDE is scope aware) Refactoring != Renaming. Refactoring benefits much more from a comprehensive test suite than renaming tools My IDE does a reasonable job of auto complete for JS with a simple search buffer of tokenized input - yup it gets it wrong sometimes. Naming convention is more useful than auto complete as it makes your code easier to read (and hence maintain) as well as rapidly imparting extra contextual info to the reader.

Joined Apr 13, 2017 • Dec 29 '25 Dropdown menu Copy link Hide About 13 years ago, the team I was on worked on a large project using TypeScript (version 0.8 at that time). What was clearly evident to me was that TypeScript was a much more suited language for large projects than JavaScript. Disclaimer: at that time, I was preferential towards CoffeeScript, or the unsuccessful GorillaScript. I try to keep this important detail in mind when I consider JavaScript. JavaScript was created by Brendan Eich in about two weeks, as a "glue" language to enable very tiny code snippets to react to events to manipulate the DOM. In that domain, the JavaScript language succeeds exceedingly well. In the domain of large applications, it has some shortcomings. TypeScript adds capability that helps support large applications. That large scale application support capability was not part of original goal of JavaScript. Of course, JavaScript hasn't just been sitting there all this time. It has also changed and improved. That evolution is incremental and evolutionary. Not radical and revolutionary. Languages like TypeScript and CoffeeScript (these days CoffeeScript 2) and ClojureScript provide for the needs of large scale applications. Programming languages are tools. Some tools are better suited for certain problem domains than other tools. Otherwise we'd just all be using the one Ultimate programming language, which would be Lisp.

Report Abuse Tabassum Khanum Posted on Nov 1, 2021 Server-Side Rendering (SSR) Vs Client-Side Rendering (CSR) # beginners # webdev # javascript # codenewbie Hey Coders! We all can agree that new-age Javascript has changed modern websites structure and the user experience drastically. Websites these days are built more like an application pretending to be a website capable of sending emails, notifications, chat, shop, payments, etc. Today's websites are so advanced, interactive, but earlier, the websites and web applications had a common strategy to follow. They prepared HTML content to be sent to the browsers at the server-side; this content was then rendered as HTML with CSS styling in the browser. Traditionally, the browser receives HTML from the server and renders it. When the user navigates to another URL, a full-page refresh is required and the server sends fresh new HTML for the new page. This is called server-side rendering. Fast forward to today. When websites have 1000s of lines of code to render and with much more complex structures. Today, websites are more than just static pages. The downfall of SSR came when the websites were not all about allowing the user to perform actions and receive a response for their action. That is why developers shifted the ever-growing method of rendering web pages on the client-side. But, here are the questions- Is SSR still relevant? If yes, where to use it. the best approach for you? Server-Side Rendering In SSR, when the user makes a request to the webpage, the server prepares the HTML page by fetching the required data from the database and sends to the user's machine over the internet. Then the browser presents all the requested actions on the user UI. All these processes of fetching data from the database to creating an HTML page and sending it to the client are done in mere milliseconds. This method is viable if all your website need is to display images/ texts, links to click, and is more on the static side. In server-side rendered pages, it is common to use snippets of jQuery to add user interactivity to each page. However, when building large apps, just jQuery is insufficient. After all, jQuery is primarily a library for DOM manipulation and it's not a framework; it does not define a clear structure and organization for your app. Client-Side Rendering Developers are approaching CSR as modern-day development is mostly about JS libraries and frameworks. The popularity of modern-age JS shifted all the attention to CSR. Client-side rendering means that a website’s JavaScript is rendered in your browser, rather than on the website’s server. So now, instead of getting all the content from the HTML doc, only the required HTML with the JS files will be rendered. The rendering time for the first upload is a bit slow. However, the next page loads will be very fast as we don't have to wait for every page render. Moreover, there is no need to reload the entire UI after every call to the server. The client-side framework manages to update UI with changed data by re-rendering only that particular DOM element. Also, a clear client-server separation scales better for larger engineering teams, as the client and server code can be developed and released independently. This is especially so at Grab when we have multiple client apps hitting the same API server. For more clear view let's see some benefits and downside of both rendering methods- Benefits of SSR - The initial page of the website load is faster as there are fewer codes to render. Good for minimal and static sites. Search engines can crawl the site for better SEO. Downsides of SSR - the site interactions are less. Slow page rendering. Full UI reloads. Frequent server requests. Benefits of CSR - The app feels more responsive and users do not see the flash between page navigations due to full-page refreshes. Fewer HTTP requests are made to the server, as the same assets do not have to be downloaded again for each page load. Clear separation of the concerns between the client and the server; you can easily build new clients for different platforms (e.g. mobile, chatbots, smartwatches) without having to modify the server code. You can also modify the technology stack on the client and server independently, as long as the API contract is not broken. Downsides of CSR - Heavier initial page load due to loading of the framework, app code, and assets required for multiple pages. There's an additional step to be done on your server which is to configure it to route all requests to a single entry point and allow client-side routing to take over from there. In most cases, requires an external library. All search engines execute JavaScript during crawling, and they may see empty content on your page. This inadvertently hurts the Search Engine Optimization (SEO) of your app. However, most of the time, when you are building apps, SEO is not the most important factor, as not all the content needs to be indexable by search engines. To overcome this, you can either server-side render your app or use services such as Prerender to "render your javascript in a browser, save the static HTML, and return that to the crawlers". When to use server-side rendering An application has a very simple UI with fewer pages/features An application has less dynamic data Read preference of the site is more than write The focus is not on rich sites and has few users When to use client-side rendering An application has a very complex UI with many pages/features An application has large and dynamic data Write preference of the site is more than reading The focus is on rich sites and a huge number of users The rendering method totally depends on the requirements and the UX plan of the client. The final call is yours whether to use SSR or CSR. I hope this article helped you to understand the basic concepts of rendering practice. Thank You for reading till the end!

Location USA Work Lead Developer & Co-founder at corpscrypt, CTO at REtech Joined Oct 1, 2019 • Nov 2 '21 Dropdown menu Copy link Hide So much to be said here in order to clear up potential misunderstandings for beginners: When deciding which technique to use, the amount of pages is not relevant. If at all, it's the other way around: the more routes your app has, the more likely SSR it the better choice. But let's look at the real why: how important is SEO? If you have an online shop or blog, the answer is probably "very important", as you depend on organic hits. If your app is about user-2-user communication (chats, private communities, etc) then the answer is probably "not so much, as the relevant content is individual. That said, most online shops even with thousands of products usually go for SSR. About history: there wasn't ever a "downfall" of SSR. SPAs simply created a new possibility and this possibly often makes more sense, and often it doesn't. Deciding when to use a fork and when to use a spoon doesn't say anything about whether or not a spoon is better than a fork. In the same way, there isn't any relationship between jQuery and SSR. This must be very confusing to read for the beginner. What OP likely meant was that we didn't have much else historically. But ask yourself why routers are always separate packages in JS frameworks. It's because it's perfectly fine to use Vue or React with SSR. Lastly, we should not forget about the impact technologies like PWA bring to this decision. Fetching and caching sites completely changes pros and cons and considerations to take. There is a huge need for SSR which can be seen when looking at technologies like next, nuxt and co. The truth is that devs tend to prefer CSR for various reasons and therefore are inclined to use it even if it's not the best choice for the task at hand.

(" DEV ," " we ," or " us ") collects, use, and discloses your personal information. What's With the Defined Terms? You'll notice that some words appear in quotes in this Privacy Policy. They're called "defined terms," and we use them so that we don't have to repeat the same language again and again. They mean the same thing in every instance, to help us make sure that this Privacy Policy is consistent. We've included the defined terms throughout because we want it to be easy for you to read them in context. 1. WHAT DOES THIS PRIVACY POLICY APPLY TO? 2. PERSONAL INFORMATION WE COLLECT 3. HOW WE USE YOUR INFORMATION 4. HOW WE DISCLOSE YOUR INFORMATION 5. YOUR PRIVACY CHOICES AND RIGHTS 6. INTERNATIONAL DATA TRANSFERS 7. RETENTION OF PERSONAL INFORMATION 8. SUPPLEMENTAL DISCLOSURES FOR CALIFORNIA RESIDENTS 9. SUPPLEMENTAL NOTICE FOR NEVADA RESIDENTS 10. CHILDREN'S INFORMATION 11. OTHER PROVISIONS 12. CONTACT US 1. WHAT DOES THIS PRIVACY POLICY APPLY TO? This Privacy Policy applies to personal information processed by us, including on our websites, mobile applications, and other online or offline offerings — basically anything we do. To make this Privacy Policy easier to read, our websites, mobile applications, and other offerings are all collectively called the " Services. " Beyond this Privacy Policy, your use of the Services is subject to our DEV Community Terms and our Forem Terms. The Services include both our own community forum at https://www.dev.to (the " DEV Community ") and the open source tool we provide called " Forem ," available at https://www.forem.com which allows our customers to create and operate their own online forums. We collect personal information from two categories of people: (1) our customers, who use Forem and our hosting services to run and host their own forums (we'll call them " Forem Operators "), and (2) the people who interact with DEV-hosted forums, including forums provided by Forem Operators utilizing Forem and separately our own DEV Community (we'll call them " Users "). An Important Note for Users Since we provide hosting services for Forem Operators, technically we also process your information on their behalf. That processing is governed by the contracts that we have in place with each Forem Operator, not this Privacy Policy. In other words, when you share your data on a DEV-hosted forum operated by a Forem Operator, we at DEV are basically just the "pipes" — we process the data on behalf of the Forem Operator, but don't do anything with it ourselves beyond what we're required to do under our contract (and by law). So, if you post your information on a DEV-powered forum provided by a Forem Operator, that Forem Operator's privacy policy applies, and any questions or requests relating to your data on that service should be directed to that Forem Operator, not us. Likewise, if you use our mobile application, you may also interact with forums that use DEV's open-source tools but do all their hosting and data collection themselves. For those forums, we at DEV have no access to your data, so be sure to read the privacy policy of any third-party hosted forum before posting. 2. PERSONAL INFORMATION WE COLLECT The categories of personal information we collect depend on whether you're a User or Forem Operator, how you interact with us, our Services, and the requirements of applicable law. Breaking it down, we collect three types of information: (1) information that you provide to us directly, (2) information we obtain automatically when you use our Services, and (3) information we get about you from other sources (such as third-party services and organizations). More details are below. A. Information You Provide to Us Directly We may collect the following personal information that you provide to us. Account Creation (for Forem Operators): We'll require your name and email address to get started, as well as some details about the Forem you want to run, such as: whether you're running the Forem on your own behalf or as part of an organization, and details about the community you want to support (how big is it, what topics does it cover, where do members currently communicate, how/if the community earns money, whether the community is open, invite-only or paid, any existing social media accounts, etc.) You'll need to tell us a bit about your personal coding background, and you'll have the option to provide your DEV username as well, if you are a member of the DEV.to community. Account Creation (for Users) : We collect name and email address from users that create an account on DEV Community. For other forums created by Forem Operators using Forem, the Forem Operator determines what information is required for User account creation for their respective forums. Interactive Features (for Users) . Like any other social network, both we and other Users of our Services may collect personal information that you submit or make available through our interactive features (e.g., messaging and chat features, commenting functionalities, forums, blogs, posts, and other social media pages). While we do have private messages that are only between you and the person you're messaging (as well as us and the Forem Operator, as applicable), any information you provide using the public sharing features of the Services, such as the information you post to your public profile or the topics you follow is public, including to recruiters and prospective employers, and is not subject to any of the privacy protections we mention in this Privacy Policy except where legally required. Please exercise caution before revealing any information that may identify you in the real world to others. Purchases . If you buy stuff on our shop site https://shop.dev.to/ (as either a User or Forem Operator), or otherwise if you pay us in connection with your use of the Forem service, we may collect personal information and details associated with your purchases, including payment information. Any payments made via our Services are processed by third-party payment processors, such as Stripe, Shopify, and PayPal. We do not directly collect or store any payment card information entered through our Services, but may receive information associated with your payment card information (e.g., your billing details). Your Communications with Us (Users and Forem Operators) . We may collect personal information, such as email address, phone number, or mailing address when you request information about our Services, register for our newsletter or loyalty program, request customer or technical support, apply for a job, or otherwise communicate with us. Surveys . We may contact you to participate in surveys. If you decide to participate, you may be asked to provide certain information, which may include personal information (for example, your home address). Sweepstakes or Contests . We may collect personal information you provide for any sweepstakes or contests that we offer. In some jurisdictions, we are required to publicly share information of sweepstakes and contest winners. Conferences, Trade Shows, and Other Events . We may collect personal information from individuals when we attend conferences, trade shows, and other events. Business Development and Strategic Partnerships . We may collect personal information from individuals and third parties to assess and pursue potential business opportunities. Job Applications . We may post job openings and opportunities on our Services. If you reply to one of these postings by submitting your application, CV and/or cover letter to us, we will collect and use your information to assess your qualifications. B. Information Collected Automatically We may collect personal information automatically when you use our Services: Automatic Data Collection . We may collect certain information automatically when you use our Services, such as your Internet protocol (IP) address, user settings, MAC address, cookie identifiers, mobile carrier, mobile advertising and other unique identifiers, browser or device information, location information (including approximate location derived from IP address), and Internet service provider. We may also automatically collect information regarding your use of our Services, such as pages that you visit before, during and after using our Services, information about the links you click, the types of content you interact with, the frequency and duration of your activities, and other information about how you use our Services. In addition, we may collect information that other people provide about you when they use our Services, including information about you when they tag you in their posts. Cookies, Pixel Tags/Web Beacons, and Other Technologies . We, as well as third parties that provide content, advertising, or other functionality on our Services, may use cookies, pixel tags, local storage, and other technologies (" Technologies ") to automatically collect information through your use of our Services. Cookies . Cookies are small text files placed in device browsers that store preferences and facilitate and enhance your experience. Pixel Tags/Web Beacons . A pixel tag (also known as a web beacon) is a piece of code embedded in our Services that collects information about engagement on our Services. The use of a pixel tag allows us to record, for example, that a user has visited a particular web page or clicked on a particular advertisement. We may also include web beacons in e-mails to understand whether messages have been opened, acted on, or forwarded. Our uses of these Technologies fall into the following general categories: Operationally Necessary . This includes Technologies that allow you access to our Services, applications, and tools that are required to identify irregular website behavior, prevent fraudulent activity and improve security or that allow you to make use of our functionality. Performance-Related . We may use Technologies to assess the performance of our Services, including as part of our analytic practices to help us understand how individuals use our Services ( see Analytics below ). Functionality-Related . We may use Technologies that allow us to offer you enhanced functionality when accessing or using our Services. This may include identifying you when you sign into our Services or keeping track of your specified preferences, interests, or past items viewed. Analytics . We may use Technologies and other third-party tools to process analytics information on our Services. Some of our analytics partners include Google Analytics. For more information,please visit Google Analytics' Privacy Policy . To learn more about how to opt-out of Google Analytics' use of your information, please click here . Social Media Platforms . Our Services may contain social media buttons such as Twitter, Facebook, GitHub, Instagram, and Twitch (that might include widgets such as the "share this" button or other interactive mini programs). These features may collect your IP address, which page you are visiting on our Services, and may set a cookie to enable the feature to function properly. Your interactions with these platforms are governed by the privacy policy of the company providing it. See the "Your Privacy Choices and Rights" section below to understand your choices regarding these Technologies. C. Information Collected from Other Sources We may obtain information about you from other sources, including through third-party services and organizations. For example, if you access our Services through a third-party application, such as an app store, a third-party login service (e.g., through Twitter, Apple, or GitHub), or a social networking site, we may collect whatever information about you from that third-party application that you have made available via your privacy settings. 3.

We always strive to safeguard your information consistent with the requirements of applicable laws. 7. RETENTION OF PERSONAL INFORMATION We store the personal information we collect as described in this Privacy Policy for as long as you use our Services or as necessary: to fulfill the purpose or purposes for which it was collected, to provide our Services, to resolve disputes, to establish legal defenses, to conduct audits, to pursue legitimate business purposes, to enforce our agreements, and to comply with applicable laws. 8. SUPPLEMENTAL DISCLOSURES FOR CALIFORNIA RESIDENTS Refer-a-Friend and Similar Incentive Programs .

For example, we may offer incentives to you such as discounts or promotional items or credit in connection with these programs, wherein you provide your personal information in exchange for a reward, or provide personal information regarding your friends or colleagues (such as their email address) and receive rewards when they sign up to use our Services. (The referred party may also receive rewards for signing up via your referral.) These programs are entirely voluntary and allow us to grow our business and provide additional benefits to you. The value of your data to us depends on how you ultimately use our Services, whereas the value of the referred party's data to us depends on whether the referred party ultimately becomes a User or Forem Operator and uses our Services. Said value will be reflected in the incentive offered in connection with each program. Accessibility . This Privacy Policy uses industry-standard technologies and was developed in line with the World Wide Web Consortium's Web Content Accessibility Guidelines, version 2.1* . * If you wish to print this policy, please do so from your web browser or by saving the page as a PDF.

Right for Minors to Remove Posted Content . Where required by law, California residents under the age of 18 may request to have their posted content or information removed from the publicly-viewable portions of the Services by contacting us directly as set forth in the "Contact Us" section below or by logging into their account and removing the content or information using our self-service tools. 9. SUPPLEMENTAL NOTICE FOR NEVADA RESIDENTS If you are a resident of Nevada, you have the right to opt-out of the sale of certain Personal Information to third parties who intend to license or sell that Personal Information.

OTHER PROVISIONS Third-Party Websites or Applications . The Services may contain links to other websites or applications, and other websites or applications may reference or link to our Services. These third-party services are not controlled by us. We encourage our users to read the privacy policies of each website and application with which they interact.

Report Abuse Henry Boisdequin Posted on Nov 29, 2020 React vs Vue vs Angular vs Svelte # react # vue # angular # svelte In this article, I'm going to cover which of the top Javascript frontend frameworks: React, Vue, Angular, or Svelte is the best at certain factors and which one is the best for you. There are going to be 5 factors which we are going to look at: popularity, community/resources, performance, learning curve, and real-world examples. Before diving into any of these factors, let's take a look at what these frameworks are. 🔵 React Developed By : Facebook Open-source : Yes Licence : MIT Licence Initial Release : March 2013 Github Repo : https://github.com/facebook/react Description : React is a JavaScript library for building user interfaces. Pros : Easy to learn and use Component-based: reusable code Performant and fast Large community Cons : JSX is required Poor documentation 🟢 Vue Developed By : Evan You Open-source : Yes Licence : MIT Licence Initial Release : Feburary 2014 Github Repo : https://github.com/vuejs/vue Description : Vue.js is a progressive, incrementally-adoptable JavaScript framework for building UI on the web. Pros : Performant and fast Component-based: reusable code Easy to learn and use Good and intuitive documentation Cons : Fewer resources compared to a framework like React Over flexibility at times 🔴 Angular Developed By : Google Open-source : Yes Licence : MIT Licence Initial Release : September 2016 Github Repo : https://github.com/angular/angular Description : Angular is a development platform for building mobile and desktop web applications using Typescript/JavaScript and other languages. Pros : Fast server performance MVC Architecture implementation Component-based: reusable code Good and intuitive documentation Cons : Steep learning curve Angular is very complex 🟠 Svelte Developed By : Rich Harris Open-source : Yes Licence : MIT Licence Initial Release : November 2016 Github Repo : https://github.com/sveltejs/svelte Description : Svelte is a new way to build web applications. It's a compiler that takes your declarative components and converts them into efficient JavaScript that surgically updates the DOM. Pros : No virtual DOM Truly reactive Easy to learn and use Component-based: reusable code Cons : Small community Confusion in variable names and syntax The 1st Factor: Popularity All of these options are extremely popular and are used by loads of developers. I'm going to compare these 4 frameworks in google trends, NPM trends, and the Stackoverflow 2020 survey results to see which one is the most popular. Note: Remember that popularity doesn't mean it has the largest community and resources. Google Trends Google trends measures the number of searches for a certain topic. Let's have a look at the results: Note: React is blue, Angular is red, Svelte is gold, Vue is green. The image above contains the trends for these 4 frontend frameworks over the past 5 years. As you can see, Angular and React are by far the most searched, with React being searched more than Angular. While Vue sits in the middle, Svelte is the clear least searched framework. Although Google Trends gives us the number of search results, it may be a bit deceiving so lets of on to NPM trends. NPM Trends NPM Trends is a tool created by John Potter, used to compare NPM packages popularity. This measures how many times a certain NPM package was downloaded. As you can see, React is clearly the most popular in terms of NPM package downloads. Angular and Vue are very similar on the chart, with them going back and forth while Svelte sits at the bottom once again. Stackoverflow 2020 Survey In February of 2020, close to 65 thousand developers filled out the Stackoverflow survey. This survey is the best in terms of what the actual developer community uses, loves, dreads, and wants. Above is the info for the most popular web frameworks. As you can see React and Angular are 2nd and 3rd but React still has a monumental lead. Vue sits happily in the middle but Svelte is nowhere to be seen. Above are the results for the most loved web frameworks. As you can see, React is still 2nd and this time Vue sits in 3rd. Angular is in the middle of the bunch, but yet again Svelte is not there. Note: Angular.js is not Angular Above are the most dreaded web frameworks. As you can see React and Vue are towards the bottom (which is good) while Angular is one of the most dreaded web frameworks. This is because React and Vue developers tend to make fun of Angular, mostly because of its predecessor Angular.js . Svelte is not on this list which is good for the framework. Explaining Svelte's "Bad" Results Some may say that Svelte performed poorly compared to the other 3 frameworks in this category. You would be right. Svelte is the new kid on the block, not many people are using it or know about it. Think of React, Vue, or Angular in their early stages: that's what Svelte is currently. Most of these frontend frameworks comparisons are between React, Vue, or Angular but since I think that Svelte is promising, I wanted to include it in this comparison. Most of the other factors, Svelte is ranking quite highly in. Wrapping up the 1st Factor: Popularity From the three different trends/surveys, we can conclude that React is the most popular out of the three but with Vue and Angular just behind. Popularity: React Angular Vue Svelte Note: it was very hard to choose between Angular and Vue since they are very close together but I think Angular just edges out Vue in the present day. The 2nd Factor: Community & Resources This factor will be about which framework has the best community and resources. This is a crucial factor as this helps you learn the technology and get help when you are stuck. We are going to be looking at the courses available and the community size behind these frameworks. Let's jump right into it! React React has a massive amount of resources and community members behind it. Firstly, they have a Spectrum chat which usually has around 200 developers looking to help you online. Also, they have a massive amount of Stackoverflow developers looking to help you. There are 262,951 Stackoverflow questions on React, one of the most active Stackoverflow tags. React also has a bunch of resources and tutorials. If you search up React tutorial there will be countless tutorials waiting for you. Here are my recommended React tutorials for getting started: Free: https://youtu.be/4UZrsTqkcW4 Paid: https://www.udemy.com/course/complete-react-developer-zero-to-mastery/ Vue Vue also has loads of resources and a large community but not as large as React. Vue has a Gitter chat with over 19,000 members. In addition, they have a massive Stackoverflow community with 68,778 questions. Where Vue really shines is its resources. Vue has more resources than I could imagine. Here are my recommended Vue tutorials for getting started: Free: https://youtu.be/e-E0UB-YDRk Paid: https://www.udemy.com/course/vuejs-2-the-complete-guide/ Angular Angular has a massive community. Their Gitter chat has over 22,489 people waiting to help you. Also, their Stackoverflow questions asked is over 238,506. Like React and Vue, Angular has a massive amount of resources to help you learn the framework. A downfall to these resources is that most of them are outdated (1-2 years old) but you can still find some great tutorials. Here are my recommended Angular tutorials for getting started: Free: https://youtu.be/Fdf5aTYRW0E Paid: https://www.udemy.com/course/the-complete-guide-to-angular-2/ Svelte Svelte has a growing community yet still has many quality tutorials and resources. An awesome guide to Svelte and their community is here: https://svelte-community.netlify.app . They have a decent Stackoverflow community with over 1,300 questions asked. Also, they have an awesome Discord community with over 1,500 members online on average. Svelte has a lot of great tutorials and resources, despite it only coming on to the world stage quite recently. Here are my recommended Svelte tutorials for getting started: Free: https://www.youtube.com/watch?v=zojEMeQGGHs&list=PL4cUxeGkcC9hlbrVO_2QFVqVPhlZmz7tO Paid: https://www.udemy.com/course/sveltejs-the-complete-guide/ Wrapping up the 2nd Factor: Community & Resources From just looking at the Stackoverflow community and the available resources, we can conclude that all of these 4 frameworks have a massive community and available resources. Community & Resources: React Vue & Angular* Svelte *I really couldn't decide between the two! The 3rd Factor: Performance In this factor, I will be going over which of these frameworks are the most performant. There are going to be three main components to this factor: speed test, startup test, and the memory allocation test. I will be using this website to compare the speed of all frameworks. Speed Test This test will compare each of the frameworks in a set of tasks and find out the speed of which they complete them. Let's have a look at the results. As you can see, just by the colours that Svelte and Vue are indeed the most performant in this category. This table has the name of the actions on one side and the results on the other. At the bottom of the table, we can see something called slowdown geometric mean. Slowdown geometric mean is an indicator of overall performance and speed by a framework. From this, we can conclude that this category ranking: Vue - 1.17 slowdown geometric mean Svelte - 1.19 slowdown geometric mean React & Angular - 1.27 slowdown geometric mean Startup Test The startup test measures how long it takes for one of these frameworks to "startup". Let's see the table. As you can see, Svelte is the clear winner. For every single one of these performance tests, Svelte is blazing fast (if you want to know how Svelte does this, move to the "Why is Svelte so performant?" section). From these results, we can create this category ranking. Svelte Vue React Angular Memory Test The memory test sees which framework takes up the least amount of memory for the same test. Let's jump into the results. Similarly to the startup test, Svelte is clearly on top. Vue and React are quite similar while Angular (once again) is the least performant. From this, we can derive this category ranking. Svelte Vue React Angular Why is Svelte so performant? TL;DR: No Virtual DOM Compiled to just JS Small bundles Before looking at why Svelte is how performant, we need to understand how Svelte works. Svelte is not compiled to JS, HTML, and CSS files. You might be thinking: what!? But that's right, instead of doing that it compiles highly optimized JS files. This means that the application needs no dependencies to start and it's blazing fast. This way no virtual DOM is needed. Your components are compiled to Javascript and the DOM doesn't need to update. Also, it also takes up little memory as it complies in highly optimized, small bundles of Javascript. Wrapping up the 3rd Factor: Performance Svelte made a huge push in this factor, blowing away the others! From the three categories, let's rank these frameworks in terms of performance. Svelte Vue React Angular The 4th Factor: Learning Curve In this factor, we will be looking at how long and how easy it is to be able to build real-world (frontend-only) applications. This is one of the most important factors if you are looking to get going with this framework quickly. Let's dive right into it. React React is super easy to learn. React almost takes no time to learn, I would even say if you are proficient at Javascript and HTML, you can learn the basics in a day. Since we are looking about how long it takes to build a real-world project, this is the list of things you need to learn: How React works JSX State Props Main Hooks useState useEffect useRef useMemo Components NPM, Bebel, Webpack, ES6+ Functional Components vs Class Components React Router Create React App, Next.js, or Gatsby Optional but recommended: Redux, Recoil, Zustand, or Providers Vue In my opinion, Vue takes a bit more time than React to build a real project. With a bit of work, you could learn the Vue fundamentals in less than 3 days. Although Vue takes longer to learn, it is definitely one of the fastest popular Javascript frameworks to learn. Here is the list of things you need to learn: How Vue Works .vue files NPM, Bebel, Webpack, ES6+ State management Vuex Components create-vue-app/Vue CLI Vue Router Declarative Rendering Conditionals and Loops Vue Instance Vue Shorthands Optional: Nuxt.js, Vuetify, NativeScript-Vue Angular Angular is a massive framework, much larger than any other in this comparison. This may be why Angular is not as performant as other frameworks such as React, Svelte, or Vue. To learn the basics of Angular, it could take a week or more. Here are the things you need to learn to build a real-world app in Angular: How Angular Works Typescript Data Types Defining Types Type Inference Interfaces Union Types Function type definitions Two-way data binding Dependency Injection Components Routing NPM, Bebel, Webpack, ES6+ Directives Templates HTTP Client Svelte One could argue that Svelte is the easiest framework to learn in this comparison. I would agree with that. Svelte's syntax is very similar to an HTML file. I would say that you could learn the Svelte basics in a day. Here are the things you need to learn to build a real-world app in Svelte: How Svelte Works .svelte files NPM, Bebel, Webpack, ES6+ Reactivity Props If, Else, Else ifs/Logic Events Binding Lifecycle Methods Context API State in Svelte Svelte Routing Wrapping up the 4th Factor: Learning Curve All these frameworks (especially Vue, Svelte, and React) are extremely easy to learn, very much so when one is already proficient with Javascript and HTML. Let's rank these technologies in terms of their learning curve! (ordered in fastest to learn to longest to learn) Svelte React Vue Angular The 5th Factor: Real-world examples In this factor, the final factor, we will be looking at some real-world examples of apps using that particular framework. At the end of this factor, the technologies won't be ranking but it's up to you to see which of these framework's syntax and way of doing things you like best. Let's dive right into it! React Top 5 Real-world companies using React : Facebook, Instagram, Whatsapp, Yahoo!, Netflix Displaying "Hello World" in React : import React from ' react ' ; function App () { return ( < div > Hello World </ div > ); } Enter fullscreen mode Exit fullscreen mode Vue Top 5 Real-world companies using Vue : NASA, Gitlab, Nintendo, Grammarly, Adobe Displaying "Hello World" in Vue : < template > <h1> Hello World </h1> </ template > Enter fullscreen mode Exit fullscreen mode Angular Top 5 Real-world companies using Angular : Google, Microsoft, Deutsche Bank, Forbes, PayPal Displaying "Hello World" in Angular : import { Component } from ' @angular/core ' ; @ Component ({ selector : ' my-app ' , template : &lt;h1&gt;Hello World&lt;/h1&gt; , }) export class AppComponent ; Enter fullscreen mode Exit fullscreen mode Svelte Top 5 Real-world companies using Svelte : Alaska Air, Godaddy, Philips, Spotify, New York Times Displaying "Hello World" in Svelte : <h1> Hello world </h1> Enter fullscreen mode Exit fullscreen mode Wrapping up the 5th Factor: Real-world Examples Wow! Some huge companies that we use on a daily basis use the frameworks that we use. This shows that all of these frameworks can be used to build apps as big as these household names. Also, the syntax of all of these frameworks is extremely intuitive and easy to learn. You can decide which one you like best! Conculsion I know, you're looking for a ranking of all of these frameworks. It really depends but to fulfil your craving for a ranking, I'll give you my personal opinion : Svelte React Vue Angular This would be my ranking but based on these 5 factors, choose whichever framework you like best and feel yourself coding every day in, all of them are awesome. I hope that you found this article interesting and maybe picked a new framework to learn (I'm going to learn Svelte)! Please let me know which frontend framework you use and why you use it.

But point 4 is subjective depending on your background and previous knowledge. To improve your post, you should add a note explaining what's your background. Finally point 5 are not similar at all. The vue example is a complete page using a reactive property. Anyway as @johnpapa said in a talk, you can achieve almost the same result with any framework, pick the one which feels right for you... :) Like comment: Like comment: 13 likes Like Comment button Reply Collapse Expand Henry Boisdequin Henry Boisdequin Henry Boisdequin Follow Programmer x Swimmer | React Dev, Machine Learning Enthusiast, Rustacean Email boisdequinhenry19@gmail.com Joined Oct 12, 2020 • Nov 29 '20 Dropdown menu Copy link Hide Yes, I agree with you! I would recommend anyone to learn the framework which feels right for you. For the Vue example, I'm not an expert at Vue and don't know a better way to do it (if you have a smaller, more concise 'hello world' example, please comment it). I will definitely work an a 'what's my background section'. To explain it know: I've been using React in all my web dev projects. I have basic knowledge of Vue, Angular, and Svelte. After looking at these 5 factors, I plan to use Svelte for my coming projects. Thanks, @stefanovualto for the feedback!

Then something similar would be: <template> <h1> Hello world! </h1> </template> Enter fullscreen mode Exit fullscreen mode Maybe a pro' for vue is that it can be adopted/used progressively without having to rely on building process (which I am assuming are mandatory for react, svelte and maybe angular). What I mean is that your previous example worked, but it wasn't comparable to the others.

"Requires JSX" a downside??? I almost stopped reading at that point. Template DSLs are more or less the same. If that's a con, doesn't support JSX could easily be seen as one. There are reasonable arguments for both sides and this shows extreme bias. Vue is "truly reactive" as well. Whatever that means. Your JS Framework Benchmark results are over 2 years old.

When I did some research and asked some other developers when they think of React they think of needing to learn JSX. For something like Svelte, all you need to know is HTML, CSS, and JS. I know that my benchmarks were two years old and I addressed this multiple times before: For the performance factor, I knew that the frameworks were a bit outdated but the general gist stated the same. Svelte 3 was released some time ago and that blows all of the other frameworks out of the water in terms of performance hence Svelte would stay on top. Vue and React are very similar in performance, Vue even says so themselves: vuejs.org/v2/guide/comparison.html. Since, Angular is a massive framework with built-in routing, etc, its performance didn't become better than Vue, React, or Svelte in its newer versions. Thanks for the new benchmark website, I will definitely be using that in the future. Also, I just read your benchmark article and its a good explanation on how these benchmarks work. Thanks for your input.

This is more explanation to that point: Firstly, for confusion in variable names, I'm talking about how Svelte handles state. Coming from React, state would only be initialized with the useState hook. In Svelte, all the variables you make is state which could be confusing for someone just learning Svelte. Also, for the confusion in syntax, I'm talking about the confusion in logic. For example, if statements in Svelte are different than the usual Javascript if statements which could cause some confusion/more learning time for beginners. There are also other examples of this.

A great pro of Svelte is its docs and tutorial on its website. I think in 1-2 years, you are going to see Svelte at least where Vue is in the search trends. Most of the search trends come from developers asking questions like how to fix this error, or how to do this but since not many people use Svelte (compared to the other frameworks) there are not many questions being asked.

Location Brisbane, Australia Work Founder at kuizto.co Joined Mar 7, 2019 • Dec 4 '20 Dropdown menu Copy link Hide Sorry @hb , you've decided to go on a touchy subject by writing this article! I will have to disagree with you on that point. I think it's perfectly okay to prefer using React. There are many reasons why it is a good choice. However, an easy learning curve isn't part of it. Just so there is no ambiguity, after having used all the Frameworks from this article - my choice goes towards Vue.js and Svelte, but I'll try to remain as objective as possible. 1) According to the State of JS survey 2018 (not using 2019, because that same question wasn't part of last year's survey). From 20,268 developers interrogated, the number #1 argument about Vue.js is an easy learning curve. For React it comes at position #11 (top 3 beings: elegant programming style, rick package ecosystem, and well-established): 2018.stateofjs.com/front-end-frame... 2018.stateofjs.com/front-end-frame... 2) Main reason why Vue.js is labelled "The Progressive JavaScript Framework", is because it is progressive to implement and to learn. Before you can get started with React, you need to know about JSX and build systems. On the other end, Vue.js can be used just by dropping a single script tag into your page and using plain HTML and CSS. This makes a huge difference in terms of approachability of the Framework. 3) Maybe less objective on this one - but from my own professional experience with both Frameworks and leading teams of developers - it usually takes Junior Developers almost twice the time to become proficient with React than with Vue.js. Firstly because of what I mentioned in point number 2. Secondly, because React has few abstraction leaks that makes performance optimisation something developers have to deal with themselves (using memoize hooks). It's a concept that is hard to understand, but essentials if working on large applications. Thirdly, because of the documentation (as you mentioned in your article). And lastly because of the fragmented ecosystem of libraries that can quickly be overwhelming for Junior Devs. Again, I think there are a lot of reasons why React can be a good choice. But not because of the learning curve.

Svelte 3 was released some time ago and that blows all of the other frameworks out of the water in terms of performance hence Svelte would stay on top. Vue and React are very similar in performance, Vue even says so themselves: vuejs.org/v2/guide/comparison.html . Since, Angular is a massive framework with built-in routing, etc, its performance didn't become better than Vue, React, or Svelte in its newer versions. For the search results, they are unpredictable. To my knowledge, there is no new kid on the block in terms of frontend Javascript frameworks. If anything, more people are using Web Assembly. As you can see from the search results graph, it goes up and down, changing all the time.

Coming from React, state would only be initialized with the useState hook. In Svelte, all the variables you make is state which could be confusing for someone just learning Svelte. Also, for the confusion in syntax, I'm talking about the confusion in logic. For example, if statements in Svelte are different than the usual Javascript if statements which could cause some confusion/more learning time for beginners. There are also other examples of this.

Report Abuse realNameHidden Posted on Nov 4, 2025 How Does HashMap Handle Hash Collisions Internally # java # collection # interview Learn how HashMap handles hash collisions internally in Java using buckets, linked lists, and trees. Understand rehashing, examples, and best practices. 🧩 Introduction Imagine a busy post office sorting thousands of letters into pigeonholes based on zip codes. Each pigeonhole represents a unique slot for a region. But what if two letters have the same zip code ? They’ll go into the same slot — and that’s okay because the post office knows how to manage them efficiently. This is exactly how HashMap in Java works internally. When two different keys produce the same hash value , it’s called a hash collision . Understanding how Java’s HashMap handles these collisions is vital for writing efficient and reliable code , especially if you work with large datasets or performance-critical applications. In this article, you’ll learn how HashMap manages collisions internally — from linked lists to balanced trees — with simple examples and analogies. ⚙️ Core Concepts Before diving into collisions, let’s understand the basic structure of a HashMap . 1. How a HashMap Stores Data A HashMap stores key-value pairs in buckets (think of them as pigeonholes). When you insert a key-value pair: The key’s hashCode() method is called. The hash value is processed using internal logic (bitwise operations). The resulting index determines which bucket the entry goes into. If two keys generate the same bucket index, a collision occurs. 2. What is a Hash Collision? A hash collision happens when two keys produce the same hash and therefore map to the same bucket index. Example: "AB" . hashCode () == "BA" . hashCode () // Hypothetical example Enter fullscreen mode Exit fullscreen mode Even though the keys are different, they land in the same bucket — creating a collision. Collisions are inevitable because the hash space is finite but the number of possible keys is infinite. 3. How HashMap Handles Collisions (Java 8 and Above) Java’s HashMap uses a combination of Linked Lists and Red-Black Trees to efficiently handle collisions. 🧱 Step 1: Linked List Chaining When a bucket collision occurs: The new key-value pair is added to the linked list inside that bucket. The list stores all entries that share the same hash index. This approach is called chaining . However, if too many collisions occur, this list can grow long — degrading performance to O(n) for lookups. 🌳 Step 2: Treeify for Better Performance To solve this, Java 8 introduced treeification : If a bucket contains more than 8 entries , the linked list is converted into a Red-Black Tree . Tree operations like search, insert, and delete then work in O(log n) time. When the number of entries in a bucket drops below 6, the tree converts back into a linked list — a process called untreeification . This balance ensures that HashMap remains both fast and memory-efficient . 4. Visual Analogy Think of buckets like parking lots: Normally, each car (key) gets its own spot (bucket). If two cars accidentally get assigned the same spot (collision), they queue up (linked list). If the queue gets too long, the system builds a multi-level parking structure (tree) to organize them efficiently. 💻 Code Examples (Java 21) Example 1: Demonstrating Hash Collisions import java.util.HashMap ; public class HashCollisionExample { public static void main ( String [] args ) { HashMap < Key , String > map = new HashMap <>(); // Two different keys but same hashCode (intentional collision) Key key1 = new Key ( 1 ); Key key2 = new Key ( 2 ); map . put ( key1 , "Value for Key1" ); map . put ( key2 , "Value for Key2" ); // Retrieve both values System . out . println ( map . get ( key1 )); // Value for Key1 System . out . println ( map . get ( key2 )); // Value for Key2 } } // Custom Key class with same hashCode for demonstration class Key { private int id ; public Key ( int id ) { this . id = id ; } @Override public int hashCode () { return 100 ; // Force hash collision } @Override public boolean equals ( Object obj ) { if ( this == obj ) return true ; if (!( obj instanceof Key )) return false ; return this . id == (( Key ) obj ). id ; } } Enter fullscreen mode Exit fullscreen mode 📝 Explanation: Even though both keys have the same hash code (collision), the equals() method ensures they’re stored and retrieved correctly in the HashMap. This shows how HashMap internally manages collisions safely . Example 2: Observing Treeification (Conceptual Demonstration) import java.util.HashMap ; public class TreeifyExample { public static void main ( String [] args ) { HashMap < Integer , String > map = new HashMap <>(); // Insert multiple elements with the same hash bucket index // (This won’t always treeify in small examples but illustrates the concept) for ( int i = 0 ; i < 20 ; i ++) { map . put ( i * 16 , "Value" + i ); } System . out . println ( "Inserted 20 elements with potential hash collisions." ); System . out . println ( "HashMap automatically optimizes performance internally!" ); } } Enter fullscreen mode Exit fullscreen mode 📝 Explanation: When multiple entries fall into the same bucket, Java automatically decides whether to maintain a linked list or convert it into a Red-Black Tree based on the threshold — optimizing lookup time. ✅ Best Practices for Working with HashMap Collisions Always Override hashCode() and equals() Together If you override one without the other, collisions can cause data inconsistency or retrieval failures. Use High-Quality Hash Functions Poorly designed hashCode() methods lead to frequent collisions, slowing down performance. Avoid Using Mutable Keys Changing a key’s field after insertion can break retrieval logic because its hash may change. Monitor Performance in Large Maps In performance-critical systems, frequent rehashing or collisions can degrade throughput — consider ConcurrentHashMap for multi-threaded scenarios. Understand Default Thresholds Knowing when treeification happens (8 entries per bucket) helps you predict memory and performance behavior. 🏁 Conclusion Understanding how HashMap handles hash collisions internally is key to mastering Java programming at a deeper level. Hash collisions aren’t bad — they’re expected. What matters is how HashMap handles them efficiently: First with linked lists (simple chaining) Then with Red-Black Trees (balanced search structure) This design ensures that even under heavy data loads, lookups and insertions remain fast and reliable. So next time you use a HashMap , you’ll know exactly what’s happening behind the scenes — Java is quietly organizing your data like a smart postmaster!

Public atproto content ( records ) is stored in per-account repositories (frequently shortened to repo ). All currently active records are stored in the repository, and current repository contents are publicly available, but both content deletions and account deletions are fully supported. The repository data structure is content-addressed (a Merkle-tree ), and every mutation of repository contents (eg, addition, removal, and updates to records) results in a new commit data hash value (CID). Commits are cryptographically signed, with rotatable signing keys, which allows recursive validation of content as a whole or in part. Repositories and their contents are canonically stored in binary DAG-CBOR format, as a graph of data objects referencing each other by content hash (CID Links). Large binary blobs are not stored directly in repositories, though they are referenced by hash ( CID ). This includes images and other media objects. Repositories can be exported as CAR files for offline backup, account migration, or other purposes. In the atproto federation architecture, the authoritative location of an account's repository is the associated Personal Data Server (PDS). An account's current PDS location is authoritatively indicated in the DID Document. In real-world use, it is expected that individual repositories will contain anywhere from dozens to millions of records. Repo Data Structure (v3) This describes version 3 of the repository binary format. Version 2 had a slightly different commit object schema, but is mostly compatible with 3 . Version 1 had a different MST fanout configuration, and an incompatible schema for commits and repository metadata. Version 1 is deprecated, no repositories in this format exist in the network, and implementations do not need to support it. At a high level, a repository is a key/value mapping where the keys are path names (as strings) and the values are records (DAG-CBOR objects). A Merkle Search Tree (MST) is used to store this mapping. This content-addressed deterministic data structure stores data in key-sorted order. It is reasonably efficient for key lookups, key range scans, and appends (assuming sorted record paths). The properties of MSTs in general are described in this academic publication: Alex Auvolat, François Taïani. Merkle Search Trees: Efficient State-Based CRDTs in Open Networks. SRDS 2019 - 38th IEEE International Symposium on Reliable Distributed Systems, Oct 2019, Lyon, France. pp.1-10, ff10.1109/SRDS.2019.00032 ( pdf ) The specific details of the MST as used in atproto repositories are described below. Repo paths are strings, while MST keys are byte arrays. Neither may be empty (zero-length). While repo path strings are currently limited to a subset of ASCII (making encoding a no-op), the encoding is specified as UTF-8. Repo paths currently have a fixed structure of <collection>/<record-key> . This means a valid, normalized NSID , followed by a / , followed by a valid Record Key . The path should not start with a leading / , and should always have exactly two path segments. The ASCII characters allowed in the entire path string are currently: letters ( A-Za-z ), digits ( 0-9 ), slash ( / ), period ( . ), hyphen ( - ), underscore ( _ ), and tilde ( ~ ). The specific path segments . and .. are not valid NSIDs or Record Keys, and will always be disallowed in repo paths. Note that repo paths for all records in the same collection are sorted together in the MST, making enumeration (via key scan) and export efficient. Additionally, the TID Record Key scheme was intentionally selected to provide chronological sorting of MST keys within the scope of a collection. Appends are more efficient than random insertions/mutations within the tree, and when enumerating records within a collection they will be in chronological order (assuming that TID generation was done correctly, which cannot be relied on in general). Commit Objects The top-level data object in a repository is a signed commit. The data fields are: did (string, required): the account DID associated with the repo, in strictly normalized form (eg, lowercase as appropriate) version (integer, required): fixed value of 3 for this repo format version data (CID link, required): pointer to the top of the repo contents tree structure (MST) rev (string, TID format, required): revision of the repo, used as a logical clock. Must increase monotonically. Recommend using current timestamp as TID; rev values in the "future" (beyond a fudge factor) should be ignored and not processed. prev (CID link, nullable): pointer (by hash) to a previous commit object for this repository. Could be used to create a chain of history, but largely unused (included for v2 backwards compatibility). In version 3 repos, this field must exist in the CBOR object, but is virtually always null . NOTE: previously specified as nullable and optional, but this caused interoperability issues. sig (byte array, required): cryptographic signature of this commit, as raw bytes An UnsignedCommit data object has all the same fields except for sig . The process for signing a commit is to populate all the data fields, and then serialize the UnsignedCommit with DAG-CBOR. The output bytes are then hashed with SHA-256, and the binary hash output (without hex encoding) is then signed using the current "signing key" for the account. The signature is then stored as raw bytes in a commit object, along with all the other data fields. The CID for a commit overall is generated by serializing a signed commit object as DAG-CBOR. See notes on the "blessed" CID format below, and in particular be sure to use the dag-cbor multicodec for CIDs linking to commit objects. Note that neither the signature itself nor the signed commit indicate either the type of key used (curve type), or the specific public key used. That information must be fetched from the account's DID document. With key rotation, verification of older commit signatures can become ambiguous. The most recent commit should always be verifiable using the current DID document. This implies that a new repository commit should be created every time the signing key is rotated. Such a commit does not need to update the data CID link. MST Structure At a high level, the repository MST is a key/value mapping where the keys are non-empty byte arrays, and the values are CID links to records. The MST data structure should be fully reproducible from such a mapping of bytestrings-to-CIDs, with exactly reproducible root CID hash (aka, the data field in commit object). Every node in the tree structure contains a set of key/CID mappings, as well as links to other sub-tree nodes. The entries and links are in key-sorted order, with all of the keys of a linked sub-tree (recursively) falling in the range corresponding to the link location. The sort order is from left (lexically first) to right (lexically latter). Each key has a depth derived from the key itself, which determines which sub-tree it ends up in. The top node in the tree contains all of the keys with the highest depth value (which for a small tree may be all depth zero, so a single node). Links to the left or right of the entire node, or between any two keys in the node, point to a sub-tree node containing keys that fall in the corresponding key range. An empty repository with no records is represented as a single MST node with an empty array of entries. This is the only situation in which a tree may contain an empty leaf node which does not either contain keys ("entries") or point to a sub-tree containing entries. The top of the tree must not be a an empty node which only points to a sub-tree. Empty intermediate nodes are allowed, as long as they point to a sub-tree which does contain entries. In other words, empty nodes must be pruned from the top and bottom of the tree, but empty intermediate nodes must be kept, such that sub-tree links do not skip a level of depth. The overall structure and shape of the MST is deterministic based on the current key/value content, regardless of the history of insertions and deletions that lead to the current contents. For the atproto MST implementation, the hash algorithm used is SHA-256 (binary output), counting "prefix zeros" in 2-bit chunks, giving a fanout of 4. To compute the depth of a key: hash the key (a byte array) with SHA-256, with binary output count the number of leading binary zeros in the hash, and divide by two, rounding down the resulting positive integer is the depth of the key Some examples, with the given ASCII strings mapping to byte arrays: 2653ae71 : depth "0" blue : depth "1" app.bsky.feed.post/454397e440ec : depth "4" app.bsky.feed.post/9adeb165882c : depth "8" There are many MST nodes in repositories, so it is important that they have a compact binary representation, for storage efficiency. Within every node, keys (byte arrays) are compressed by eliding common prefixes, with each entry indicating how many bytes it shares with the previous key in the array. The first entry in the array for a given node must contain the full key, and a common prefix length of 0. This key compaction is internal to nodes, it does not extend across multiple nodes in the tree. The compaction scheme is mandatory, to ensure that the MST structure is deterministic across implementations. The node data schema fields are: l ("left", CID link, nullable): link to sub-tree Node on a lower level and with all keys sorting before keys at this node e ("entries", array of objects, required): ordered list of TreeEntry objects p ("prefixlen", integer, required): count of bytes shared with previous TreeEntry in this Node (if any) k ("keysuffix", byte array, required): remainder of key for this TreeEntry, after "prefixlen" have been removed v ("value", CID Link, required): link to the record data (CBOR) for this entry t ("tree", CID Link, nullable): link to a sub-tree Node at a lower level which has keys sorting after this TreeEntry's key (to the "right"), but before the next TreeEntry's key in this Node (if any) When parsing MST data structures, the depth and sort order of keys should be verified. This is particularly true for untrusted inputs, but is simplest to just verify every time. Additional checks on node size and other parameters of the tree structure also need to be limited; see the "Security Considerations" section of this document. CID Formats The IPFS CID specification is very flexible, and supports a wide variety of hash types, a field indicating the type of content being linked to, and various string encoding options. These features are valuable to allow evolution of the repo format over time, but to maximize interoperability among implementations, only a specific "blessed" set of CID types are allowed. The blessed format for commit objects and MST node objects, when linking to commit objects, MST nodes (aka, data , or MST internal links), or records (aka, MST leaf nodes to records), is: CIDv1 Multibase: binary serialization within DAG-CBOR (or base32 for JSON mappings) Multicodec: dag-cbor (0x71) Multihash: sha-256 with 256 bits (0x12) In the context of repositories, it is also desirable for the overall data structure to be reproducible given the contents, so the allowed CID types are strictly constrained and enforced. Commit objects with non-compliant prev or data links are considered invalid. MST Node objects with non-compliant links to other MST Node objects are considered invalid, and the entire MST data structure invalid. More flexibility is allowed in processing the "leaf" links from MST to records, and implementations should retain the exact CID links used for these mappings, instead of normalizing. Implementations should strictly follow the CID blessed format when generating new CID Links to records. CAR File Serialization The standard file format for storing data objects is Content Addressable aRchives (CAR). The standard repository export format for atproto repositories is CAR v1 , which have file suffix .car and mimetype application/vnd.ipld.car . The CARv1 format is very simple. It contains a small metadata header (which can indicate one or more "root" CID links), and then a series of binary "blocks", each of which is a data object. In the context of atproto repositories: The first element of the CAR roots metadata array must be the CID of the most relevant Commit object. for a generic export, this is the current (most recent) commit. additional CIDs may also be present in the roots array, with (for now) undefined meaning or order For full exports, the full repo structure must be included for the indicated commit, which includes all records and all MST nodes The order of blocks within the CAR file is not currently defined or restricted. implementations may have a "preferred" ordering, but should be tolerant of unexpected ordering Additional blocks, including records, may or may not be included in the CAR file When importing CAR files, note that there may existing dangling CID references. For example, repositories may contain CID Links to blobs or records in other repositories, and the blocks corresponding to those blobs or references would likely not be included in the CAR file. The CARv1 specification is agnostic about the same block appearing multiple times in the same file ("Duplicate Blocks)". Implementations should be robust to both duplication and de-duplication of blocks, and should also ignore any unnecessary or unlinked blocks. Repository Diffs An updated version of the Synchronization protocol is being rolled out to the live network in early 2025. There is a "Sync v1.1" proposal document and an update blog post with deployment details. The written specifications will be updated soon. A concept which supports efficient synchronization of data between independent services is "diffs" of repository trees between different revisions. The basic principle is that a repository diff contains all the data (commit object, MST nodes, and records) that have changed between an older revision and the current revision of a repo. The diff can be "applied" to the older mirror of the repository, and the result will be the complete MST tree at the current (newer) commit revision. Repo diffs can be serialized as CAR files, sometimes referred to as "CAR slices". Some details about diff CAR slices: same format, version, and atproto-specific constraints as full repo export CAR files blocks "should" be de-duplicated by CID (only one copy included), though receiving implementations must be resilient to duplication the root CID indicated in the CAR header (the first element of roots ) should point to the commit block (which must be included) any required blocks must be included even if they have appeared in the history of the repository previously. eg, if a record is created in rev C, deleted in rev F, and re-created in rev N, the diff "since F" must include the record block all "created" records must be included any records which have been "deleted" and do not exist in the current repo should not be included any records which have been "updated" should include the final version, and should not include the previous version all MST nodes in the current repo which didn't exist in the previous repo version must be included with the exception of removed record data, the diff may include additional blocks, which receivers should ignore. however, diffs which intentionally contain a large amount of irrelevant block data to consume network or compute resources are considered a form of network abuse. The diff is a partial Merkle tree, including a signed commit, and can be partially verified. This means that an observer which has successfully resolved the identity of the relevant account (including cryptographic public keys) can verify certain aspects of the data. The diff is a reliable "proof chain" for creation and updates of records: an observer can verify that the new or updated records have the specific record values in the overall repo as of the commit revision. If the observer knows of specific records (by repo path, or by full AT-URI) that have been deleted, they can verify that those records no longer exist in the repo as of the final commit revision. However, an observer which does not know the full state of the repository at the "older" revision can not reliably enumerate all of the records that have been removed from the repository. Such an observer also can not see the previous values of deleted or updated records, either as full values or by CID. Note that the later is an intentional design goal for the diff concept: it is desired that content deletion happen rapidly and not "draw attention" to the content which has been deleted. It is technically possible for "archival" observers to track deletion events and lookup the previous content value, but this requires additional resources and effort. Sometimes repo diffs are generated automatically. For example, every commit to a repo can result in a diff against the immediately preceding commit. In other contexts, diffs are generated on demand: a diff can be requested "since" an arbitrary previous revision. It is not expected that repo hosts support generating diffs between two arbitrary revisions, only "from" an arbitrary older revision and the current revision. Repo hosts are not required to maintain a complete history of prior commits/revisions, and in some cases (such as account migration) may never have had prior repo history. Some details about how to interpret and service requests for diffs "since" a prior revision: it is helpful to track internally the commit revision when a block (record or MST node) was created or re-created. This enables querying blocks "since" a point in time "since" revisions are not expected to be an exact match for example, if a repo had a sequence of commits "333", "666", "999", and a "since" value of "444" was requested, the changes in "666" and "999" should be included, as if the "since" parameter was "666".. a host is allowed to include additional history, but is encouraged to return the minimal or most granular requested data for example, a host may have "compacted" repo rev history to a smaller number of commits. If a repo had commit history "288", "300", "320", "340", "400", and got a request "since" 340, it might return all changes since 300. Hosts are encouraged to return the smallest diff when possible (eg, “since” 340), but clients should be resilient. if a host receives a “since” request earlier than the oldest available revision for a repository, it should return the full repository. This may happen if the host does not have the complete history of the repository. for example, if a repository had revisions "140", "150", and "160", then migrated to a new PDS and revisions continued "161" and "170", if the new PDS is asked for a diff "since" 150, the new PDS would probably need to return the full repository, because the earliest revision it would be aware of was "160" or "161" (depending on how migration was implemented). In the specific case of chained commit-to-commit diffs which appear on the firehose, diffs should be "minimal": they should not contain additional records or additional history. Security Considerations Repositories are untrusted input: accounts have full control over repository contents, and PDS instances have full control over binary encoding. It is important to handle possible denial of service vectors from both hostile actors or accidental situations (eg, corrupted data or buggy implementations). Generic precautions should be followed with CBOR decoding: a maximum serialized object size, a maximum recursion depth for nested fields, maximum memory budget for deserialized data, etc. Some CBOR libraries include these precautions by default, but others do not. The efficiency of the MST data structure depends on key hashes being relatively randomly dispersed. Because accounts have control over Record Keys, they can mine for sets of record keys with particular depths and sorting order, which result in inefficient tree shapes, which can cause both large storage overhead, and network amplification in the context of federation streams. To protect against these attacks, implementations should limit the number of TreeEntries per Node to a statistically unlikely maximum length. It may also be necessary to limit the overall depth of the repo, or other parameters, to prevent more sophisticated key mining attacks. When importing CAR files, the completeness of the repository structure should be verified. Additional unrelated blocks might be included in the CAR structure; care should be taken when injecting CAR contents directly in to backend block storage, to ensure resources are not wasted on un-referenced blocks. There may also be issues with cross-account contamination from CAR imports, for example previously-deleted records re-appearing via CAR import from an unrelated account. Possible Future Changes An optional in-repo mechanism for storing multiple versions of the same record (by path) may be implemented. Eg, adding additional path field to indicate the version by CID, timestamp, or monotonically increasing version integer. Mechanisms for storing metadata associated with each record are being considered, for example, generic label, re-use rights, or hashtag metadata. This would allow mutating the metadata without mutating the record itself, and make some metadata generic across lexicons. Repo path restrictions may be relaxed in other ways, including fewer or additional path segments, more allowed characters (including non-ASCII), etc. Paths will always be valid Unicode strings, mapped to MST keys (byte arrays) by UTF-8 encoding. At the overall atproto specification level, additional "blessed" cryptographic algorithms may be added over time. Likewise, additional CID formats to reference records and blobs may be added. Internal CID format changes would require a repo format version bump. Repository CAR exports may include linked "blobs" (larger binary files). This might become the default, or a configurable option, or some another mechanism for blob export might be chosen (eg, .tar or .zip export). Record content could conceivably be something other than DAG-CBOR some day. This would probably be a repo format version bump. Note that it is possible to efficiently wrap other data formats in a DAG-CBOR wrapper (via a byte array field), or to have a small DAG-CBOR record type that links to a blob in arbitrary format. Repository CAR exports may end up with a preferred block ordering scheme specified. The CARv2 file format, which includes optimizations for some use cases, may be adopted in some form. Adding optional fields to commit and MST node objects may or may not result in a repo format version change. Changing the MST fanout, or any changes to the current MST fields, would be a full repo version change. Previous Accounts Next Blobs © Copyright 2026 . All rights reserved.

Report Abuse Henry Boisdequin Posted on Nov 29, 2020 React vs Vue vs Angular vs Svelte # react # vue # angular # svelte In this article, I'm going to cover which of the top Javascript frontend frameworks: React, Vue, Angular, or Svelte is the best at certain factors and which one is the best for you. There are going to be 5 factors which we are going to look at: popularity, community/resources, performance, learning curve, and real-world examples. Before diving into any of these factors, let's take a look at what these frameworks are. 🔵 React Developed By : Facebook Open-source : Yes Licence : MIT Licence Initial Release : March 2013 Github Repo : https://github.com/facebook/react Description : React is a JavaScript library for building user interfaces. Pros : Easy to learn and use Component-based: reusable code Performant and fast Large community Cons : JSX is required Poor documentation 🟢 Vue Developed By : Evan You Open-source : Yes Licence : MIT Licence Initial Release : Feburary 2014 Github Repo : https://github.com/vuejs/vue Description : Vue.js is a progressive, incrementally-adoptable JavaScript framework for building UI on the web. Pros : Performant and fast Component-based: reusable code Easy to learn and use Good and intuitive documentation Cons : Fewer resources compared to a framework like React Over flexibility at times 🔴 Angular Developed By : Google Open-source : Yes Licence : MIT Licence Initial Release : September 2016 Github Repo : https://github.com/angular/angular Description : Angular is a development platform for building mobile and desktop web applications using Typescript/JavaScript and other languages. Pros : Fast server performance MVC Architecture implementation Component-based: reusable code Good and intuitive documentation Cons : Steep learning curve Angular is very complex 🟠 Svelte Developed By : Rich Harris Open-source : Yes Licence : MIT Licence Initial Release : November 2016 Github Repo : https://github.com/sveltejs/svelte Description : Svelte is a new way to build web applications. It's a compiler that takes your declarative components and converts them into efficient JavaScript that surgically updates the DOM. Pros : No virtual DOM Truly reactive Easy to learn and use Component-based: reusable code Cons : Small community Confusion in variable names and syntax The 1st Factor: Popularity All of these options are extremely popular and are used by loads of developers. I'm going to compare these 4 frameworks in google trends, NPM trends, and the Stackoverflow 2020 survey results to see which one is the most popular. Note: Remember that popularity doesn't mean it has the largest community and resources. Google Trends Google trends measures the number of searches for a certain topic. Let's have a look at the results: Note: React is blue, Angular is red, Svelte is gold, Vue is green. The image above contains the trends for these 4 frontend frameworks over the past 5 years. As you can see, Angular and React are by far the most searched, with React being searched more than Angular. While Vue sits in the middle, Svelte is the clear least searched framework. Although Google Trends gives us the number of search results, it may be a bit deceiving so lets of on to NPM trends. NPM Trends NPM Trends is a tool created by John Potter, used to compare NPM packages popularity. This measures how many times a certain NPM package was downloaded. As you can see, React is clearly the most popular in terms of NPM package downloads. Angular and Vue are very similar on the chart, with them going back and forth while Svelte sits at the bottom once again. Stackoverflow 2020 Survey In February of 2020, close to 65 thousand developers filled out the Stackoverflow survey. This survey is the best in terms of what the actual developer community uses, loves, dreads, and wants. Above is the info for the most popular web frameworks. As you can see React and Angular are 2nd and 3rd but React still has a monumental lead. Vue sits happily in the middle but Svelte is nowhere to be seen. Above are the results for the most loved web frameworks. As you can see, React is still 2nd and this time Vue sits in 3rd. Angular is in the middle of the bunch, but yet again Svelte is not there. Note: Angular.js is not Angular Above are the most dreaded web frameworks. As you can see React and Vue are towards the bottom (which is good) while Angular is one of the most dreaded web frameworks. This is because React and Vue developers tend to make fun of Angular, mostly because of its predecessor Angular.js . Svelte is not on this list which is good for the framework. Explaining Svelte's "Bad" Results Some may say that Svelte performed poorly compared to the other 3 frameworks in this category. You would be right. Svelte is the new kid on the block, not many people are using it or know about it. Think of React, Vue, or Angular in their early stages: that's what Svelte is currently. Most of these frontend frameworks comparisons are between React, Vue, or Angular but since I think that Svelte is promising, I wanted to include it in this comparison. Most of the other factors, Svelte is ranking quite highly in. Wrapping up the 1st Factor: Popularity From the three different trends/surveys, we can conclude that React is the most popular out of the three but with Vue and Angular just behind. Popularity: React Angular Vue Svelte Note: it was very hard to choose between Angular and Vue since they are very close together but I think Angular just edges out Vue in the present day. The 2nd Factor: Community & Resources This factor will be about which framework has the best community and resources. This is a crucial factor as this helps you learn the technology and get help when you are stuck. We are going to be looking at the courses available and the community size behind these frameworks. Let's jump right into it! React React has a massive amount of resources and community members behind it. Firstly, they have a Spectrum chat which usually has around 200 developers looking to help you online. Also, they have a massive amount of Stackoverflow developers looking to help you. There are 262,951 Stackoverflow questions on React, one of the most active Stackoverflow tags. React also has a bunch of resources and tutorials. If you search up React tutorial there will be countless tutorials waiting for you. Here are my recommended React tutorials for getting started: Free: https://youtu.be/4UZrsTqkcW4 Paid: https://www.udemy.com/course/complete-react-developer-zero-to-mastery/ Vue Vue also has loads of resources and a large community but not as large as React. Vue has a Gitter chat with over 19,000 members. In addition, they have a massive Stackoverflow community with 68,778 questions. Where Vue really shines is its resources. Vue has more resources than I could imagine. Here are my recommended Vue tutorials for getting started: Free: https://youtu.be/e-E0UB-YDRk Paid: https://www.udemy.com/course/vuejs-2-the-complete-guide/ Angular Angular has a massive community. Their Gitter chat has over 22,489 people waiting to help you. Also, their Stackoverflow questions asked is over 238,506. Like React and Vue, Angular has a massive amount of resources to help you learn the framework. A downfall to these resources is that most of them are outdated (1-2 years old) but you can still find some great tutorials. Here are my recommended Angular tutorials for getting started: Free: https://youtu.be/Fdf5aTYRW0E Paid: https://www.udemy.com/course/the-complete-guide-to-angular-2/ Svelte Svelte has a growing community yet still has many quality tutorials and resources. An awesome guide to Svelte and their community is here: https://svelte-community.netlify.app . They have a decent Stackoverflow community with over 1,300 questions asked. Also, they have an awesome Discord community with over 1,500 members online on average. Svelte has a lot of great tutorials and resources, despite it only coming on to the world stage quite recently. Here are my recommended Svelte tutorials for getting started: Free: https://www.youtube.com/watch?v=zojEMeQGGHs&list=PL4cUxeGkcC9hlbrVO_2QFVqVPhlZmz7tO Paid: https://www.udemy.com/course/sveltejs-the-complete-guide/ Wrapping up the 2nd Factor: Community & Resources From just looking at the Stackoverflow community and the available resources, we can conclude that all of these 4 frameworks have a massive community and available resources. Community & Resources: React Vue & Angular* Svelte *I really couldn't decide between the two! The 3rd Factor: Performance In this factor, I will be going over which of these frameworks are the most performant. There are going to be three main components to this factor: speed test, startup test, and the memory allocation test. I will be using this website to compare the speed of all frameworks. Speed Test This test will compare each of the frameworks in a set of tasks and find out the speed of which they complete them. Let's have a look at the results. As you can see, just by the colours that Svelte and Vue are indeed the most performant in this category. This table has the name of the actions on one side and the results on the other. At the bottom of the table, we can see something called slowdown geometric mean. Slowdown geometric mean is an indicator of overall performance and speed by a framework. From this, we can conclude that this category ranking: Vue - 1.17 slowdown geometric mean Svelte - 1.19 slowdown geometric mean React & Angular - 1.27 slowdown geometric mean Startup Test The startup test measures how long it takes for one of these frameworks to "startup". Let's see the table. As you can see, Svelte is the clear winner. For every single one of these performance tests, Svelte is blazing fast (if you want to know how Svelte does this, move to the "Why is Svelte so performant?" section). From these results, we can create this category ranking. Svelte Vue React Angular Memory Test The memory test sees which framework takes up the least amount of memory for the same test. Let's jump into the results. Similarly to the startup test, Svelte is clearly on top. Vue and React are quite similar while Angular (once again) is the least performant. From this, we can derive this category ranking. Svelte Vue React Angular Why is Svelte so performant? TL;DR: No Virtual DOM Compiled to just JS Small bundles Before looking at why Svelte is how performant, we need to understand how Svelte works. Svelte is not compiled to JS, HTML, and CSS files. You might be thinking: what!? But that's right, instead of doing that it compiles highly optimized JS files. This means that the application needs no dependencies to start and it's blazing fast. This way no virtual DOM is needed. Your components are compiled to Javascript and the DOM doesn't need to update. Also, it also takes up little memory as it complies in highly optimized, small bundles of Javascript. Wrapping up the 3rd Factor: Performance Svelte made a huge push in this factor, blowing away the others! From the three categories, let's rank these frameworks in terms of performance. Svelte Vue React Angular The 4th Factor: Learning Curve In this factor, we will be looking at how long and how easy it is to be able to build real-world (frontend-only) applications. This is one of the most important factors if you are looking to get going with this framework quickly. Let's dive right into it. React React is super easy to learn. React almost takes no time to learn, I would even say if you are proficient at Javascript and HTML, you can learn the basics in a day. Since we are looking about how long it takes to build a real-world project, this is the list of things you need to learn: How React works JSX State Props Main Hooks useState useEffect useRef useMemo Components NPM, Bebel, Webpack, ES6+ Functional Components vs Class Components React Router Create React App, Next.js, or Gatsby Optional but recommended: Redux, Recoil, Zustand, or Providers Vue In my opinion, Vue takes a bit more time than React to build a real project. With a bit of work, you could learn the Vue fundamentals in less than 3 days. Although Vue takes longer to learn, it is definitely one of the fastest popular Javascript frameworks to learn. Here is the list of things you need to learn: How Vue Works .vue files NPM, Bebel, Webpack, ES6+ State management Vuex Components create-vue-app/Vue CLI Vue Router Declarative Rendering Conditionals and Loops Vue Instance Vue Shorthands Optional: Nuxt.js, Vuetify, NativeScript-Vue Angular Angular is a massive framework, much larger than any other in this comparison. This may be why Angular is not as performant as other frameworks such as React, Svelte, or Vue. To learn the basics of Angular, it could take a week or more. Here are the things you need to learn to build a real-world app in Angular: How Angular Works Typescript Data Types Defining Types Type Inference Interfaces Union Types Function type definitions Two-way data binding Dependency Injection Components Routing NPM, Bebel, Webpack, ES6+ Directives Templates HTTP Client Svelte One could argue that Svelte is the easiest framework to learn in this comparison. I would agree with that. Svelte's syntax is very similar to an HTML file. I would say that you could learn the Svelte basics in a day. Here are the things you need to learn to build a real-world app in Svelte: How Svelte Works .svelte files NPM, Bebel, Webpack, ES6+ Reactivity Props If, Else, Else ifs/Logic Events Binding Lifecycle Methods Context API State in Svelte Svelte Routing Wrapping up the 4th Factor: Learning Curve All these frameworks (especially Vue, Svelte, and React) are extremely easy to learn, very much so when one is already proficient with Javascript and HTML. Let's rank these technologies in terms of their learning curve! (ordered in fastest to learn to longest to learn) Svelte React Vue Angular The 5th Factor: Real-world examples In this factor, the final factor, we will be looking at some real-world examples of apps using that particular framework. At the end of this factor, the technologies won't be ranking but it's up to you to see which of these framework's syntax and way of doing things you like best. Let's dive right into it! React Top 5 Real-world companies using React : Facebook, Instagram, Whatsapp, Yahoo!, Netflix Displaying "Hello World" in React : import React from ' react ' ; function App () { return ( < div > Hello World </ div > ); } Enter fullscreen mode Exit fullscreen mode Vue Top 5 Real-world companies using Vue : NASA, Gitlab, Nintendo, Grammarly, Adobe Displaying "Hello World" in Vue : < template > <h1> Hello World </h1> </ template > Enter fullscreen mode Exit fullscreen mode Angular Top 5 Real-world companies using Angular : Google, Microsoft, Deutsche Bank, Forbes, PayPal Displaying "Hello World" in Angular : import { Component } from ' @angular/core ' ; @ Component ({ selector : ' my-app ' , template : &lt;h1&gt;Hello World&lt;/h1&gt; , }) export class AppComponent ; Enter fullscreen mode Exit fullscreen mode Svelte Top 5 Real-world companies using Svelte : Alaska Air, Godaddy, Philips, Spotify, New York Times Displaying "Hello World" in Svelte : <h1> Hello world </h1> Enter fullscreen mode Exit fullscreen mode Wrapping up the 5th Factor: Real-world Examples Wow! Some huge companies that we use on a daily basis use the frameworks that we use. This shows that all of these frameworks can be used to build apps as big as these household names. Also, the syntax of all of these frameworks is extremely intuitive and easy to learn. You can decide which one you like best! Conculsion I know, you're looking for a ranking of all of these frameworks. It really depends but to fulfil your craving for a ranking, I'll give you my personal opinion : Svelte React Vue Angular This would be my ranking but based on these 5 factors, choose whichever framework you like best and feel yourself coding every day in, all of them are awesome. I hope that you found this article interesting and maybe picked a new framework to learn (I'm going to learn Svelte)! Please let me know which frontend framework you use and why you use it.

But point 4 is subjective depending on your background and previous knowledge. To improve your post, you should add a note explaining what's your background. Finally point 5 are not similar at all. The vue example is a complete page using a reactive property. Anyway as @johnpapa said in a talk, you can achieve almost the same result with any framework, pick the one which feels right for you... :) Like comment: Like comment: 13 likes Like Comment button Reply Collapse Expand Henry Boisdequin Henry Boisdequin Henry Boisdequin Follow Programmer x Swimmer | React Dev, Machine Learning Enthusiast, Rustacean Email boisdequinhenry19@gmail.com Joined Oct 12, 2020 • Nov 29 '20 Dropdown menu Copy link Hide Yes, I agree with you! I would recommend anyone to learn the framework which feels right for you.

I will definitely work an a 'what's my background section'. To explain it know: I've been using React in all my web dev projects. I have basic knowledge of Vue, Angular, and Svelte.

Then something similar would be: <template> <h1> Hello world! </h1> </template> Enter fullscreen mode Exit fullscreen mode Maybe a pro' for vue is that it can be adopted/used progressively without having to rely on building process (which I am assuming are mandatory for react, svelte and maybe angular). What I mean is that your previous example worked, but it wasn't comparable to the others.

"Requires JSX" a downside??? I almost stopped reading at that point. Template DSLs are more or less the same. If that's a con, doesn't support JSX could easily be seen as one. There are reasonable arguments for both sides and this shows extreme bias. Vue is "truly reactive" as well. Whatever that means. Your JS Framework Benchmark results are over 2 years old. Svelte and Vue 3 are both out and in the current results. He now publishes them per Chrome version. Here are the latest: krausest.github.io/js-framework-be... .

When I did some research and asked some other developers when they think of React they think of needing to learn JSX. For something like Svelte, all you need to know is HTML, CSS, and JS. I know that my benchmarks were two years old and I addressed this multiple times before: For the performance factor, I knew that the frameworks were a bit outdated but the general gist stated the same. Svelte 3 was released some time ago and that blows all of the other frameworks out of the water in terms of performance hence Svelte would stay on top. Vue and React are very similar in performance, Vue even says so themselves: vuejs.org/v2/guide/comparison.html. Since, Angular is a massive framework with built-in routing, etc, its performance didn't become better than Vue, React, or Svelte in its newer versions. Thanks for the new benchmark website, I will definitely be using that in the future. Also, I just read your benchmark article and its a good explanation on how these benchmarks work.

This is more explanation to that point: Firstly, for confusion in variable names, I'm talking about how Svelte handles state. Coming from React, state would only be initialized with the useState hook. In Svelte, all the variables you make is state which could be confusing for someone just learning Svelte. Also, for the confusion in syntax, I'm talking about the confusion in logic. For example, if statements in Svelte are different than the usual Javascript if statements which could cause some confusion/more learning time for beginners. There are also other examples of this.

A great pro of Svelte is its docs and tutorial on its website. I think in 1-2 years, you are going to see Svelte at least where Vue is in the search trends. Most of the search trends come from developers asking questions like how to fix this error, or how to do this but since not many people use Svelte (compared to the other frameworks) there are not many questions being asked.

Location Brisbane, Australia Work Founder at kuizto.co Joined Mar 7, 2019 • Dec 4 '20 Dropdown menu Copy link Hide Sorry @hb , you've decided to go on a touchy subject by writing this article! I will have to disagree with you on that point. I think it's perfectly okay to prefer using React. There are many reasons why it is a good choice. However, an easy learning curve isn't part of it. Just so there is no ambiguity, after having used all the Frameworks from this article - my choice goes towards Vue.js and Svelte, but I'll try to remain as objective as possible. 1) According to the State of JS survey 2018 (not using 2019, because that same question wasn't part of last year's survey). From 20,268 developers interrogated, the number #1 argument about Vue.js is an easy learning curve. For React it comes at position #11 (top 3 beings: elegant programming style, rick package ecosystem, and well-established): 2018.stateofjs.com/front-end-frame... 2018.stateofjs.com/front-end-frame... 2) Main reason why Vue.js is labelled "The Progressive JavaScript Framework", is because it is progressive to implement and to learn. Before you can get started with React, you need to know about JSX and build systems. On the other end, Vue.js can be used just by dropping a single script tag into your page and using plain HTML and CSS. This makes a huge difference in terms of approachability of the Framework. 3) Maybe less objective on this one - but from my own professional experience with both Frameworks and leading teams of developers - it usually takes Junior Developers almost twice the time to become proficient with React than with Vue.js. Firstly because of what I mentioned in point number 2. Secondly, because React has few abstraction leaks that makes performance optimisation something developers have to deal with themselves (using memoize hooks). It's a concept that is hard to understand, but essentials if working on large applications. Thirdly, because of the documentation (as you mentioned in your article). And lastly because of the fragmented ecosystem of libraries that can quickly be overwhelming for Junior Devs. Again, I think there are a lot of reasons why React can be a good choice. But not because of the learning curve.

Report Abuse Karun Japhet Posted on Dec 27, 2025 • Originally published at karun.me Efficient logback logging on JVM # java # performance # programming # tutorial Efficient logging that doesn't bring your application down is simple to setup but is often overlooked. Here are some quick tips on how to achieve exactly that Async Logging Most applications these days should have a single (console) appender. This can be linked up with your log aggregator of choice. If your application cannot aggregate logs off the console stream, file is your next best alternative. Wrap each of your appenders with an async appender and add the async appender to your root logger. Every call to the logger creates a log event. In synchronous logging, that log event was processed and writes were made to all appender streams before the application continued. Since most stream writes involve I/O, this meant the application would wait for I/O before continuining thereby slowing it down. With async logging, the event gets pushed to a log level specific in memory queue. These events are processed and consumed by the appenders asynchronously. Since the application can continue after a log event has been published to the queue, asynchronous logging works quicker (as long as I/O is the long pole in the tent that is publishing log messages) Here's a sample configuration: <configuration> <appender name= "FILE" class= "ch.qos.logback.core.FileAppender" > <file> myapp.log </file> <encoder> <pattern> %logger{35} - %msg%n </pattern> </encoder> </appender> <appender name= "ASYNC-FILE" class= "ch.qos.logback.classic.AsyncAppender" > <appender-ref ref= "FILE" /> <queueSize> 1024 </queueSize> <neverBlock> false </neverBlock> </appender> <root> <appender-ref ref= "ASYNC-FILE" /> </root> </configuration> Enter fullscreen mode Exit fullscreen mode Every queue has a configurable depth. The depth of the queue is based on how much memory you have and expected ratio in rates of messages coming in through the application and the messages being published through the I/O bottleneck. If you hit max queue depth on either the WARN or ERROR queues, further statements for those levels become synchronous. If you hit more than 80% of the max queue depth on any other level, the system will start dropping log statements (due to discardingThreshold=20 by default and neverBlock=true ). Therefore, under high load, you can lose INFO , DEBUG and TRACE log messages. This behaviour is acceptable for most cases except specific critical statements (like audit logs). For such cases, you can add asynchronous appenders that are allowed to block. The percentage of depth after which messages are dropped is configurable. You can make info/debug logs synchronous at 100% too if needed by changing the neverBlock=false (which is the default behaviour). All of this information is available on logback’s documentation . Writing log statements Async logs only work more efficiently because the production of events is synchronous (and hopefully a quick task) and the processing of events (which requires IO) is a slow task. However if production of log messages takes long time , async logging will not make things better. When you’re printing a large amount of data or if the creation of the log message is an expensive operation, use the following kind of log statement // style 1: java string interpolation; inefficient and hard to read :P logger . info ( "Large object value was " + largeObject1 + " and long operation printed " + largeObject2 . longOperation ()) // style 2: scala string interpolation; inefficient but easy to read logger . info ( s "Large object value was $largeObject1 and long operation printed ${largeObject2.longOperation()}" ) // style 3: logback based string interpolation; efficient but inconvenient to read logger . info ( "Large object value was {} and long operation printed {}" , largeObject1 , largeObject2 . longOperation ()) Enter fullscreen mode Exit fullscreen mode While the scala interpolation (style 2) is the easiest to read, we should only do it when the objects being printed are small (small-ish strings or primitives). Rule of thumb: For quick statements, use style 2. For large statements, use style 3 (sacrifices readability for efficiency) Never use style 1 :P Using LazyLogging as opposed to creating loggers yourself Use lazy logging . It internally uses loggers that wraps yours code (during compile time) with if checks to not process log statements if the specific log level doesn’t need to be printed ( using macros ). Worried about performance due to extra if conditions? You shouldn’t. Modern processors contain black magic called branch prediction that reduce the effect of statements such as this to be effectively nothing. IMO, every scala project should use lazy logging. It’s light on dependencies and has a nice implementation that makes your logging more efficient run faster for fractionally slower compilation .

Report Abuse Technmsrisai Posted on Jan 9 Tools Don’t Fix Broken Systems — Design Does # systems # architecture # productivity # software Developers understand this instinctively: you can’t fix a bad architecture by adding more libraries. Yet businesses do this all the time. When operations feel slow or chaotic, the default response is to introduce another tool — a CRM, a dashboard, an automation platform. The assumption is that tooling will create structure. It rarely does. The Real Failure Mode: No System Design Most business software implementations fail for the same reason poorly designed systems fail: no clear source of truth unclear state transitions manual overrides everywhere logic scattered across people instead of processes From a systems perspective, this is technical debt — just in human form. Adding more tools without fixing flow only increases coupling and reduces observability. Businesses Are Distributed Systems Sales, operations, finance, and support behave like independent services: asynchronous event-driven stateful But unlike well-designed systems, many businesses lack: defined interfaces clear ownership predictable handoffs Software gets blamed for this, but the issue exists before the software is introduced. Why “Implementation” Is an Engineering Problem Good implementation starts the same way good system design does: Model the workflow Where does information originate? What events change state? Design for failure What happens when data is missing? Who resolves exceptions? Minimize friction If logging data feels optional, it will be skipped. Build observability Reports should answer real questions, not look impressive. When these principles are ignored, adoption drops and teams route around the system. A Common Anti-Pattern A typical setup looks like this: CRM for leads spreadsheets for tracking chat for approvals email for escalation At that point, the “system” exists only in people’s heads. From an engineering lens, this is a brittle design with zero guarantees. What Actually Works The best implementations I’ve seen follow one rule: Design the process first. Then choose the tool. When workflows are clear: tools become interchangeable automation becomes predictable data becomes trustworthy This mindset is what companies like Technetmark focus on — treating implementation as system design, not configuration. Final Thought Developers know this already: software amplifies structure. If the structure is weak, the software exposes it. If the structure is sound, the software disappears into the background. Business tooling is no different. Top comments (0) Subscribe Personal Trusted User Create template Templates let you quickly answer FAQs or store snippets for re-use.

(" DEV ," " we ," or " us ") collects, use, and discloses your personal information. What's With the Defined Terms? You'll notice that some words appear in quotes in this Privacy Policy. They're called "defined terms," and we use them so that we don't have to repeat the same language again and again. They mean the same thing in every instance, to help us make sure that this Privacy Policy is consistent. We've included the defined terms throughout because we want it to be easy for you to read them in context. 1. WHAT DOES THIS PRIVACY POLICY APPLY TO? 2. PERSONAL INFORMATION WE COLLECT 3. HOW WE USE YOUR INFORMATION 4. HOW WE DISCLOSE YOUR INFORMATION 5. YOUR PRIVACY CHOICES AND RIGHTS 6. INTERNATIONAL DATA TRANSFERS 7. RETENTION OF PERSONAL INFORMATION 8. SUPPLEMENTAL DISCLOSURES FOR CALIFORNIA RESIDENTS 9. SUPPLEMENTAL NOTICE FOR NEVADA RESIDENTS 10. CHILDREN'S INFORMATION 11. OTHER PROVISIONS 12. CONTACT US 1. WHAT DOES THIS PRIVACY POLICY APPLY TO? This Privacy Policy applies to personal information processed by us, including on our websites, mobile applications, and other online or offline offerings — basically anything we do. To make this Privacy Policy easier to read, our websites, mobile applications, and other offerings are all collectively called the " Services. " Beyond this Privacy Policy, your use of the Services is subject to our DEV Community Terms and our Forem Terms. The Services include both our own community forum at https://www.dev.to (the " DEV Community ") and the open source tool we provide called " Forem ," available at https://www.forem.com which allows our customers to create and operate their own online forums. We collect personal information from two categories of people: (1) our customers, who use Forem and our hosting services to run and host their own forums (we'll call them " Forem Operators "), and (2) the people who interact with DEV-hosted forums, including forums provided by Forem Operators utilizing Forem and separately our own DEV Community (we'll call them " Users "). An Important Note for Users Since we provide hosting services for Forem Operators, technically we also process your information on their behalf. That processing is governed by the contracts that we have in place with each Forem Operator, not this Privacy Policy. In other words, when you share your data on a DEV-hosted forum operated by a Forem Operator, we at DEV are basically just the "pipes" — we process the data on behalf of the Forem Operator, but don't do anything with it ourselves beyond what we're required to do under our contract (and by law). So, if you post your information on a DEV-powered forum provided by a Forem Operator, that Forem Operator's privacy policy applies, and any questions or requests relating to your data on that service should be directed to that Forem Operator, not us. Likewise, if you use our mobile application, you may also interact with forums that use DEV's open-source tools but do all their hosting and data collection themselves. For those forums, we at DEV have no access to your data, so be sure to read the privacy policy of any third-party hosted forum before posting. 2. PERSONAL INFORMATION WE COLLECT The categories of personal information we collect depend on whether you're a User or Forem Operator, how you interact with us, our Services, and the requirements of applicable law. Breaking it down, we collect three types of information: (1) information that you provide to us directly, (2) information we obtain automatically when you use our Services, and (3) information we get about you from other sources (such as third-party services and organizations). More details are below. A. Information You Provide to Us Directly We may collect the following personal information that you provide to us. Account Creation (for Forem Operators): We'll require your name and email address to get started, as well as some details about the Forem you want to run, such as: whether you're running the Forem on your own behalf or as part of an organization, and details about the community you want to support (how big is it, what topics does it cover, where do members currently communicate, how/if the community earns money, whether the community is open, invite-only or paid, any existing social media accounts, etc.) You'll need to tell us a bit about your personal coding background, and you'll have the option to provide your DEV username as well, if you are a member of the DEV.to community. Account Creation (for Users) : We collect name and email address from users that create an account on DEV Community. For other forums created by Forem Operators using Forem, the Forem Operator determines what information is required for User account creation for their respective forums. Interactive Features (for Users) . Like any other social network, both we and other Users of our Services may collect personal information that you submit or make available through our interactive features (e.g., messaging and chat features, commenting functionalities, forums, blogs, posts, and other social media pages). While we do have private messages that are only between you and the person you're messaging (as well as us and the Forem Operator, as applicable), any information you provide using the public sharing features of the Services, such as the information you post to your public profile or the topics you follow is public, including to recruiters and prospective employers, and is not subject to any of the privacy protections we mention in this Privacy Policy except where legally required. Please exercise caution before revealing any information that may identify you in the real world to others. Purchases . If you buy stuff on our shop site https://shop.dev.to/ (as either a User or Forem Operator), or otherwise if you pay us in connection with your use of the Forem service, we may collect personal information and details associated with your purchases, including payment information. Any payments made via our Services are processed by third-party payment processors, such as Stripe, Shopify, and PayPal. We do not directly collect or store any payment card information entered through our Services, but may receive information associated with your payment card information (e.g., your billing details). Your Communications with Us (Users and Forem Operators) . We may collect personal information, such as email address, phone number, or mailing address when you request information about our Services, register for our newsletter or loyalty program, request customer or technical support, apply for a job, or otherwise communicate with us. Surveys . We may contact you to participate in surveys. If you decide to participate, you may be asked to provide certain information, which may include personal information (for example, your home address). Sweepstakes or Contests .

(The referred party may also receive rewards for signing up via your referral.) These programs are entirely voluntary and allow us to grow our business and provide additional benefits to you. The value of your data to us depends on how you ultimately use our Services, whereas the value of the referred party's data to us depends on whether the referred party ultimately becomes a User or Forem Operator and uses our Services.

Report Abuse realNameHidden Posted on Nov 4, 2025 How Does HashMap Handle Hash Collisions Internally # java # collection # interview Learn how HashMap handles hash collisions internally in Java using buckets, linked lists, and trees. Understand rehashing, examples, and best practices. 🧩 Introduction Imagine a busy post office sorting thousands of letters into pigeonholes based on zip codes. Each pigeonhole represents a unique slot for a region. But what if two letters have the same zip code ? They’ll go into the same slot — and that’s okay because the post office knows how to manage them efficiently. This is exactly how HashMap in Java works internally. When two different keys produce the same hash value , it’s called a hash collision . Understanding how Java’s HashMap handles these collisions is vital for writing efficient and reliable code , especially if you work with large datasets or performance-critical applications. In this article, you’ll learn how HashMap manages collisions internally — from linked lists to balanced trees — with simple examples and analogies. ⚙️ Core Concepts Before diving into collisions, let’s understand the basic structure of a HashMap . 1. How a HashMap Stores Data A HashMap stores key-value pairs in buckets (think of them as pigeonholes). When you insert a key-value pair: The key’s hashCode() method is called. The hash value is processed using internal logic (bitwise operations). The resulting index determines which bucket the entry goes into. If two keys generate the same bucket index, a collision occurs. 2. What is a Hash Collision? A hash collision happens when two keys produce the same hash and therefore map to the same bucket index. Example: "AB" . hashCode () == "BA" . hashCode () // Hypothetical example Enter fullscreen mode Exit fullscreen mode Even though the keys are different, they land in the same bucket — creating a collision. Collisions are inevitable because the hash space is finite but the number of possible keys is infinite. 3. How HashMap Handles Collisions (Java 8 and Above) Java’s HashMap uses a combination of Linked Lists and Red-Black Trees to efficiently handle collisions. 🧱 Step 1: Linked List Chaining When a bucket collision occurs: The new key-value pair is added to the linked list inside that bucket. The list stores all entries that share the same hash index. This approach is called chaining . However, if too many collisions occur, this list can grow long — degrading performance to O(n) for lookups. 🌳 Step 2: Treeify for Better Performance To solve this, Java 8 introduced treeification : If a bucket contains more than 8 entries , the linked list is converted into a Red-Black Tree . Tree operations like search, insert, and delete then work in O(log n) time. When the number of entries in a bucket drops below 6, the tree converts back into a linked list — a process called untreeification . This balance ensures that HashMap remains both fast and memory-efficient . 4. Visual Analogy Think of buckets like parking lots: Normally, each car (key) gets its own spot (bucket). If two cars accidentally get assigned the same spot (collision), they queue up (linked list). If the queue gets too long, the system builds a multi-level parking structure (tree) to organize them efficiently. 💻 Code Examples (Java 21) Example 1: Demonstrating Hash Collisions import java.util.HashMap ; public class HashCollisionExample { public static void main ( String [] args ) { HashMap < Key , String > map = new HashMap <>(); // Two different keys but same hashCode (intentional collision) Key key1 = new Key ( 1 ); Key key2 = new Key ( 2 ); map . put ( key1 , "Value for Key1" ); map . put ( key2 , "Value for Key2" ); // Retrieve both values System . out . println ( map . get ( key1 )); // Value for Key1 System . out . println ( map . get ( key2 )); // Value for Key2 } } // Custom Key class with same hashCode for demonstration class Key { private int id ; public Key ( int id ) { this . id = id ; } @Override public int hashCode () { return 100 ; // Force hash collision } @Override public boolean equals ( Object obj ) { if ( this == obj ) return true ; if (!( obj instanceof Key )) return false ; return this . id == (( Key ) obj ). id ; } } Enter fullscreen mode Exit fullscreen mode 📝 Explanation: Even though both keys have the same hash code (collision), the equals() method ensures they’re stored and retrieved correctly in the HashMap. This shows how HashMap internally manages collisions safely . Example 2: Observing Treeification (Conceptual Demonstration) import java.util.HashMap ; public class TreeifyExample { public static void main ( String [] args ) { HashMap < Integer , String > map = new HashMap <>(); // Insert multiple elements with the same hash bucket index // (This won’t always treeify in small examples but illustrates the concept) for ( int i = 0 ; i < 20 ; i ++) { map . put ( i * 16 , "Value" + i ); } System . out . println ( "Inserted 20 elements with potential hash collisions." ); System . out . println ( "HashMap automatically optimizes performance internally!" ); } } Enter fullscreen mode Exit fullscreen mode 📝 Explanation: When multiple entries fall into the same bucket, Java automatically decides whether to maintain a linked list or convert it into a Red-Black Tree based on the threshold — optimizing lookup time. ✅ Best Practices for Working with HashMap Collisions Always Override hashCode() and equals() Together If you override one without the other, collisions can cause data inconsistency or retrieval failures. Use High-Quality Hash Functions Poorly designed hashCode() methods lead to frequent collisions, slowing down performance. Avoid Using Mutable Keys Changing a key’s field after insertion can break retrieval logic because its hash may change. Monitor Performance in Large Maps In performance-critical systems, frequent rehashing or collisions can degrade throughput — consider ConcurrentHashMap for multi-threaded scenarios. Understand Default Thresholds Knowing when treeification happens (8 entries per bucket) helps you predict memory and performance behavior. 🏁 Conclusion Understanding how HashMap handles hash collisions internally is key to mastering Java programming at a deeper level. Hash collisions aren’t bad — they’re expected. What matters is how HashMap handles them efficiently: First with linked lists (simple chaining) Then with Red-Black Trees (balanced search structure) This design ensures that even under heavy data loads, lookups and insertions remain fast and reliable. So next time you use a HashMap , you’ll know exactly what’s happening behind the scenes — Java is quietly organizing your data like a smart postmaster!

(" DEV ," " we ," or " us ") collects, use, and discloses your personal information. What's With the Defined Terms? You'll notice that some words appear in quotes in this Privacy Policy. They're called "defined terms," and we use them so that we don't have to repeat the same language again and again. They mean the same thing in every instance, to help us make sure that this Privacy Policy is consistent. We've included the defined terms throughout because we want it to be easy for you to read them in context. 1. WHAT DOES THIS PRIVACY POLICY APPLY TO? 2. PERSONAL INFORMATION WE COLLECT 3. HOW WE USE YOUR INFORMATION 4. HOW WE DISCLOSE YOUR INFORMATION 5. YOUR PRIVACY CHOICES AND RIGHTS 6. INTERNATIONAL DATA TRANSFERS 7. RETENTION OF PERSONAL INFORMATION 8. SUPPLEMENTAL DISCLOSURES FOR CALIFORNIA RESIDENTS 9. SUPPLEMENTAL NOTICE FOR NEVADA RESIDENTS 10. CHILDREN'S INFORMATION 11. OTHER PROVISIONS 12. CONTACT US 1. WHAT DOES THIS PRIVACY POLICY APPLY TO? This Privacy Policy applies to personal information processed by us, including on our websites, mobile applications, and other online or offline offerings — basically anything we do. To make this Privacy Policy easier to read, our websites, mobile applications, and other offerings are all collectively called the " Services. " Beyond this Privacy Policy, your use of the Services is subject to our DEV Community Terms and our Forem Terms. The Services include both our own community forum at https://www.dev.to (the " DEV Community ") and the open source tool we provide called " Forem ," available at https://www.forem.com which allows our customers to create and operate their own online forums. We collect personal information from two categories of people: (1) our customers, who use Forem and our hosting services to run and host their own forums (we'll call them " Forem Operators "), and (2) the people who interact with DEV-hosted forums, including forums provided by Forem Operators utilizing Forem and separately our own DEV Community (we'll call them " Users "). An Important Note for Users Since we provide hosting services for Forem Operators, technically we also process your information on their behalf. That processing is governed by the contracts that we have in place with each Forem Operator, not this Privacy Policy. In other words, when you share your data on a DEV-hosted forum operated by a Forem Operator, we at DEV are basically just the "pipes" — we process the data on behalf of the Forem Operator, but don't do anything with it ourselves beyond what we're required to do under our contract (and by law). So, if you post your information on a DEV-powered forum provided by a Forem Operator, that Forem Operator's privacy policy applies, and any questions or requests relating to your data on that service should be directed to that Forem Operator, not us. Likewise, if you use our mobile application, you may also interact with forums that use DEV's open-source tools but do all their hosting and data collection themselves. For those forums, we at DEV have no access to your data, so be sure to read the privacy policy of any third-party hosted forum before posting. 2. PERSONAL INFORMATION WE COLLECT The categories of personal information we collect depend on whether you're a User or Forem Operator, how you interact with us, our Services, and the requirements of applicable law. Breaking it down, we collect three types of information: (1) information that you provide to us directly, (2) information we obtain automatically when you use our Services, and (3) information we get about you from other sources (such as third-party services and organizations). More details are below. A. Information You Provide to Us Directly We may collect the following personal information that you provide to us. Account Creation (for Forem Operators): We'll require your name and email address to get started, as well as some details about the Forem you want to run, such as: whether you're running the Forem on your own behalf or as part of an organization, and details about the community you want to support (how big is it, what topics does it cover, where do members currently communicate, how/if the community earns money, whether the community is open, invite-only or paid, any existing social media accounts, etc.) You'll need to tell us a bit about your personal coding background, and you'll have the option to provide your DEV username as well, if you are a member of the DEV.to community. Account Creation (for Users) : We collect name and email address from users that create an account on DEV Community. For other forums created by Forem Operators using Forem, the Forem Operator determines what information is required for User account creation for their respective forums. Interactive Features (for Users) . Like any other social network, both we and other Users of our Services may collect personal information that you submit or make available through our interactive features (e.g., messaging and chat features, commenting functionalities, forums, blogs, posts, and other social media pages). While we do have private messages that are only between you and the person you're messaging (as well as us and the Forem Operator, as applicable), any information you provide using the public sharing features of the Services, such as the information you post to your public profile or the topics you follow is public, including to recruiters and prospective employers, and is not subject to any of the privacy protections we mention in this Privacy Policy except where legally required. Please exercise caution before revealing any information that may identify you in the real world to others. Purchases . If you buy stuff on our shop site https://shop.dev.to/ (as either a User or Forem Operator), or otherwise if you pay us in connection with your use of the Forem service, we may collect personal information and details associated with your purchases, including payment information. Any payments made via our Services are processed by third-party payment processors, such as Stripe, Shopify, and PayPal. We do not directly collect or store any payment card information entered through our Services, but may receive information associated with your payment card information (e.g., your billing details). Your Communications with Us (Users and Forem Operators) . We may collect personal information, such as email address, phone number, or mailing address when you request information about our Services, register for our newsletter or loyalty program, request customer or technical support, apply for a job, or otherwise communicate with us. Surveys . We may contact you to participate in surveys. If you decide to participate, you may be asked to provide certain information, which may include personal information (for example, your home address). Sweepstakes or Contests . We may collect personal information you provide for any sweepstakes or contests that we offer. In some jurisdictions, we are required to publicly share information of sweepstakes and contest winners. Conferences, Trade Shows, and Other Events . We may collect personal information from individuals when we attend conferences, trade shows, and other events. Business Development and Strategic Partnerships . We may collect personal information from individuals and third parties to assess and pursue potential business opportunities. Job Applications . We may post job openings and opportunities on our Services. If you reply to one of these postings by submitting your application, CV and/or cover letter to us, we will collect and use your information to assess your qualifications. B. Information Collected Automatically We may collect personal information automatically when you use our Services: Automatic Data Collection . We may collect certain information automatically when you use our Services, such as your Internet protocol (IP) address, user settings, MAC address, cookie identifiers, mobile carrier, mobile advertising and other unique identifiers, browser or device information, location information (including approximate location derived from IP address), and Internet service provider. We may also automatically collect information regarding your use of our Services, such as pages that you visit before, during and after using our Services, information about the links you click, the types of content you interact with, the frequency and duration of your activities, and other information about how you use our Services. In addition, we may collect information that other people provide about you when they use our Services, including information about you when they tag you in their posts. Cookies, Pixel Tags/Web Beacons, and Other Technologies . We, as well as third parties that provide content, advertising, or other functionality on our Services, may use cookies, pixel tags, local storage, and other technologies (" Technologies ") to automatically collect information through your use of our Services. Cookies . Cookies are small text files placed in device browsers that store preferences and facilitate and enhance your experience. Pixel Tags/Web Beacons . A pixel tag (also known as a web beacon) is a piece of code embedded in our Services that collects information about engagement on our Services. The use of a pixel tag allows us to record, for example, that a user has visited a particular web page or clicked on a particular advertisement. We may also include web beacons in e-mails to understand whether messages have been opened, acted on, or forwarded. Our uses of these Technologies fall into the following general categories: Operationally Necessary . This includes Technologies that allow you access to our Services, applications, and tools that are required to identify irregular website behavior, prevent fraudulent activity and improve security or that allow you to make use of our functionality. Performance-Related . We may use Technologies to assess the performance of our Services, including as part of our analytic practices to help us understand how individuals use our Services ( see Analytics below ). Functionality-Related . We may use Technologies that allow us to offer you enhanced functionality when accessing or using our Services. This may include identifying you when you sign into our Services or keeping track of your specified preferences, interests, or past items viewed. Analytics . We may use Technologies and other third-party tools to process analytics information on our Services. Some of our analytics partners include Google Analytics. For more information,please visit Google Analytics' Privacy Policy . To learn more about how to opt-out of Google Analytics' use of your information, please click here . Social Media Platforms . Our Services may contain social media buttons such as Twitter, Facebook, GitHub, Instagram, and Twitch (that might include widgets such as the "share this" button or other interactive mini programs). These features may collect your IP address, which page you are visiting on our Services, and may set a cookie to enable the feature to function properly. Your interactions with these platforms are governed by the privacy policy of the company providing it. See the "Your Privacy Choices and Rights" section below to understand your choices regarding these Technologies. C. Information Collected from Other Sources We may obtain information about you from other sources, including through third-party services and organizations. For example, if you access our Services through a third-party application, such as an app store, a third-party login service (e.g., through Twitter, Apple, or GitHub), or a social networking site, we may collect whatever information about you from that third-party application that you have made available via your privacy settings. 3.

We always strive to safeguard your information consistent with the requirements of applicable laws. 7. RETENTION OF PERSONAL INFORMATION We store the personal information we collect as described in this Privacy Policy for as long as you use our Services or as necessary: to fulfill the purpose or purposes for which it was collected, to provide our Services, to resolve disputes, to establish legal defenses, to conduct audits, to pursue legitimate business purposes, to enforce our agreements, and to comply with applicable laws. 8. SUPPLEMENTAL DISCLOSURES FOR CALIFORNIA RESIDENTS Refer-a-Friend and Similar Incentive Programs . As described above in the How We Use Your Personal Information section ("Share Content with Friends or Colleagues" subsection), we may offer referral programs or other incentivized data collection programs. For example, we may offer incentives to you such as discounts or promotional items or credit in connection with these programs, wherein you provide your personal information in exchange for a reward, or provide personal information regarding your friends or colleagues (such as their email address) and receive rewards when they sign up to use our Services. (The referred party may also receive rewards for signing up via your referral.) These programs are entirely voluntary and allow us to grow our business and provide additional benefits to you. The value of your data to us depends on how you ultimately use our Services, whereas the value of the referred party's data to us depends on whether the referred party ultimately becomes a User or Forem Operator and uses our Services. Said value will be reflected in the incentive offered in connection with each program. Accessibility . This Privacy Policy uses industry-standard technologies and was developed in line with the World Wide Web Consortium's Web Content Accessibility Guidelines, version 2.1* . * If you wish to print this policy, please do so from your web browser or by saving the page as a PDF.

Where required by law, California residents under the age of 18 may request to have their posted content or information removed from the publicly-viewable portions of the Services by contacting us directly as set forth in the "Contact Us" section below or by logging into their account and removing the content or information using our self-service tools. 9.

Report Abuse Andrey Kolkov Posted on Jan 12 Smart Coding vs Vibe Coding: Engineering Discipline in the Age of AI # ai # programming # productivity # architecture In January 2026, Linus Torvalds admitted to using AI for Python code generation: "I know more about analog filters than Python." Anthropic CEO Dario Amodei claims that 90% of code at the company is now written by AI. The world is changing. But here's the nuance: Torvalds uses AI for hobby projects, not for the Linux kernel. And at Anthropic, every line of AI code has an engineer behind it making architectural decisions. This isn't coincidence — it's Smart Coding. The rise of AI-powered coding assistants has created a fascinating split in the developer community. On one side, there's Vibe Coding — an intuitive, flow-based approach where developers ride the wave of AI suggestions. On the other, Smart Coding — a disciplined methodology that leverages AI as an accelerator while maintaining engineering rigor. This isn't about rejecting AI tools. It's about using them intelligently. What is Vibe Coding? The term "Vibe Coding" emerged organically in developer communities to describe a particular workflow: Describe what you want in natural language Accept AI-generated code with minimal review If it works, ship it If it breaks, ask AI to fix it Repeat until something sticks Vibe Coding feels productive. You're shipping features fast. The dopamine hits keep coming. But there's a hidden cost accumulating in the background. Characteristics of Vibe Coding: Prompt-first, understanding-second approach Heavy reliance on AI for debugging AI-generated code Shallow comprehension of the codebase "It works, don't touch it" mentality Technical debt accumulation goes unnoticed The Problem with Pure Vibe Coding Let me be clear: Vibe Coding isn't inherently wrong. For prototypes, hackathons, or throwaway scripts, it's perfectly fine. The problem arises when it becomes the default mode for production systems. The Debugging Trap When you don't understand the code you've shipped, debugging becomes a guessing game. You're essentially asking AI to fix code that AI generated, without being able to verify whether the fix introduces new problems. It's turtles all the way down. The Architecture Blindspot AI assistants optimize locally. They solve the immediate problem in the current file. They don't see the broader system architecture. Vibe Coding accumulates local optimizations that often conflict at the system level. The Knowledge Gap Every hour spent Vibe Coding is an hour not spent building mental models. Over time, this compounds. Senior Vibe Coders can have years of experience but struggle with fundamentals because they've outsourced understanding to AI. Introducing Smart Coding Smart Coding is an engineering-first approach that treats AI as a powerful accelerator, not a replacement for understanding. The core principle: You drive. AI accelerates. The Smart Coding Workflow: Understand the problem domain first Design the solution architecture Use AI to accelerate implementation of well-defined components Review and comprehend every line before committing Validate against your mental model of the system Refactor AI output to match project conventions The Five Principles of Smart Coding 1. Architecture Ownership You own the system design. AI can suggest patterns, but you decide the structure. Before writing any code, you should be able to sketch the component diagram on a whiteboard. Smart Coder's checklist before using AI: ☐ I can explain what this component does ☐ I know how it interacts with other components ☐ I understand the data flow ☐ I've identified edge cases ☐ I know how I'll test this Enter fullscreen mode Exit fullscreen mode 2. Comprehension Before Commit Never commit code you can't explain. This isn't about memorizing syntax — it's about understanding behavior. If AI generates a solution, trace through it mentally. Modify it. Break it intentionally. Then fix it yourself. # Vibe Coding approach: # "AI, write a rate limiter" # *copies output, moves on* # Smart Coding approach: # "AI, write a rate limiter using token bucket algorithm" # *reviews output* # "Why did you choose this bucket refill strategy?" # *understands tradeoffs* # *adapts to project's specific requirements* # *adds tests for edge cases I identified* Enter fullscreen mode Exit fullscreen mode 3. Targeted Acceleration Use AI for well-scoped, clearly defined tasks. The more precise your prompt, the more useful the output. Smart Coders spend time crafting detailed specifications before engaging AI. Low-value AI usage: "Build me a user authentication system" High-value AI usage: "Implement a JWT refresh token rotation mechanism where the refresh token is invalidated after single use, with a 5-second grace period for concurrent requests. Use Redis for token blacklisting." 4. Continuous Validation Smart Coders don't trust — they verify. Every AI suggestion gets validated against: Type safety Edge cases Performance implications Security considerations Project conventions // AI suggested this: const getUser = async ( id : string ) => { return await db . users . findUnique ({ where : { id } }); }; // Smart Coder asks: // - What if id is undefined? // - What if user doesn't exist? // - Should this throw or return null? // - Is there logging/monitoring needed? // - Does this match our error handling patterns? Enter fullscreen mode Exit fullscreen mode 5. Deliberate Learning Every AI interaction is a learning opportunity. When AI suggests an unfamiliar pattern, don't just use it — understand it. Build a knowledge base. The goal is to eventually be able to write that code yourself. Smart Coder's learning loop: 1. AI suggests solution using pattern X 2. Research pattern X independently 3. Understand when to apply it 4. Understand when NOT to apply it 5. Add to personal knowledge base 6. Next time, specify pattern X in the prompt proactively Enter fullscreen mode Exit fullscreen mode Smart Coding in Practice Code Review Mindset Treat AI output the same way you'd treat a junior developer's pull request. It might be correct, but it needs scrutiny. Look for: Unnecessary complexity Missing error handling Hardcoded values that should be configurable Deviations from project style Missing tests The 70/30 Rule A practical heuristic developed from working on 35+ production projects: spend 70% of your time on architecture, understanding, and validation. Let AI accelerate the remaining 30% — the mechanical implementation work. This ratio might seem counterintuitive. "If AI can write code, shouldn't I use it more?" The answer is no. The 70% investment is what makes the 30% valuable. Without understanding, AI output is just random characters that happen to compile. Prompt Engineering as Specification Smart Coders recognize that writing good prompts is essentially writing specifications. The discipline of crafting precise prompts improves your ability to think through problems systematically. Poor prompt: "Add caching to this function" Smart prompt: "Add caching to this function with: - TTL: 5 minutes - Cache key: hash of input parameters - Cache invalidation: on related entity update - Fallback: proceed without cache if Redis unavailable - Metrics: track hit/miss ratio - Must not cache error responses" Enter fullscreen mode Exit fullscreen mode The smart prompt isn't just better for AI — it's a mini design document that clarifies your own thinking. AI as Your Research Assistant One of the most underutilized aspects of AI-assisted development is using AI agents as research tools. Smart Coders leverage this capability extensively: Pattern Discovery Ask your AI agent to search for implementations in other languages or frameworks. Want to implement a state machine in Go? Have AI fetch examples from Rust, Elixir, or Java ecosystems. Cross-pollination of ideas across language boundaries often reveals elegant patterns you wouldn't discover otherwise. Smart research workflow: 1. "Search for state machine implementations in Rust" 2. "Download and analyze this crate's source" 3. "Run the examples locally and explain the design decisions" 4. "How would this pattern translate to Go idioms?" Enter fullscreen mode Exit fullscreen mode Local Validation Don't just read about patterns — run them. Ask AI to clone repositories, execute examples, and explain runtime behavior. Seeing code in action builds intuition that documentation alone cannot provide. Comparative Analysis When facing architectural decisions, use AI to research how different ecosystems solve the same problem. Database connection pooling, error handling strategies, dependency injection — every language community has developed its own idioms. Understanding multiple approaches gives you the vocabulary to make informed choices. Adapting Patterns: From Research to Idiomatic Code Here's a critical mistake many developers make: they find an elegant pattern in Rust or Haskell and copy it directly to Go or Python. This rarely works well. The Pattern Translation Problem Every language has its own idioms, conventions, and "best practices" that evolve over time. A pattern that's idiomatic in Rust might be anti-idiomatic in Go. Direct translation often produces code that: Fights the language instead of leveraging it Confuses other developers on the team Misses language-specific optimizations Ignores ecosystem conventions The Smart Translation Workflow 1. Research: Find pattern in source language (e.g., Rust) → Understand the CONCEPT, not just the code 2. Extract: Identify the core problem being solved → What invariant is being maintained? → What guarantee is being provided? 3. Search: Find current best practices in target language → "What's the idiomatic way to do X in Go in 2025?" → Check recent blog posts, conference talks, popular libraries 4. Synthesize: Combine concept + target idioms → Apply the insight using target language conventions 5. Validate: Review with language-specific linters and experts → Does this feel natural in the target ecosystem? Enter fullscreen mode Exit fullscreen mode Example: Result Type Pattern You discover Rust's Result<T, E> pattern and want error handling like this in Go. ❌ Wrong approach: Copy Rust's Result type to Go type Result[T any] struct { value T err error } func (r Result[T]) Unwrap() T { ... } func (r Result[T]) Map(...) Result[T] { ... } // This fights Go's conventions and confuses Go developers Enter fullscreen mode Exit fullscreen mode ✅ Smart approach: Research current Go best practices Step 1: Understand Rust's goal → explicit error handling, no ignored errors Step 2: Search "Go error handling best practices 2025" Step 3: Find current idioms: - Multiple return values (value, error) - errors.Is() and errors.As() for checking - Error wrapping with fmt.Errorf("%w", err) - Sentinel errors for expected conditions Step 4: Apply Rust's INSIGHT (explicit handling) using Go's IDIOMS // Idiomatic Go that achieves similar goals: func Process(input string) (Result, error) { data, err := fetch(input) if err != nil { return Result{}, fmt.Errorf("process %s: %w", input, err) } // ... explicit handling at every step } Enter fullscreen mode Exit fullscreen mode The "Best Practices Refresh" Step Languages evolve. What was idiomatic Go in 2018 might be outdated in 2025. Always include a "refresh" step: Smart Coder's translation checklist: ☐ Found interesting pattern in language X ☐ Understood the core concept/problem ☐ Searched for CURRENT best practices in target language ☐ Checked recent (last 12 months) articles and talks ☐ Reviewed how popular libraries solve this today ☐ Adapted pattern to target language idioms ☐ Validated with language-specific tooling Enter fullscreen mode Exit fullscreen mode Practical Prompt Pattern When asking AI to help with translation: Poor prompt: "Translate this Rust state machine to Go" Smart prompt: "I found this state machine pattern in Rust [code]. I want to achieve similar guarantees in Go. First, search for current Go best practices for state machines (2025). Then show me an idiomatic Go implementation that: - Follows current Go conventions - Uses appropriate Go patterns (interfaces, channels if needed) - Would pass a code review by experienced Go developers" Enter fullscreen mode Exit fullscreen mode This ensures you get code that belongs in your target ecosystem, not a mechanical translation that feels foreign. The Hybrid Workflow: Combining Smart and Vibe In practice, the most effective developers don't choose between Smart Coding and Vibe Coding. They combine them strategically. The Exploration-Consolidation Cycle Phase 1: Vibe (Exploration) When you're entering unknown territory — unfamiliar API, new algorithm, unclear requirements — Vibe Coding is your reconnaissance tool. Exploration goals: - Does this approach work at all? - What are the hidden constraints? - Where are the edge cases? - How does the API actually behave vs. documentation? Enter fullscreen mode Exit fullscreen mode Let AI generate quick prototypes. Don't worry about code quality. You're not building — you're learning. This spike might take 30 minutes and produce throwaway code. That's fine. The value is in the knowledge gained. Phase 2: Smart (Consolidation) Once you understand the problem space, switch modes. Now you have: Validated assumptions Discovered edge cases Working mental model Concrete examples to reference This is when Smart Coding shines. You're not exploring anymore — you're engineering. Take the insights from your Vibe exploration and build the proper implementation with full rigor. When to Switch Modes Start with Vibe when: Requirements are fuzzy You've never used this technology before You need to validate feasibility quickly The cost of throwaway code is low Switch to Smart when: Core approach is validated You're building for production Others will maintain this code The component is critical path The Spike-and-Rebuild Pattern A practical workflow that combines both approaches: 1. Vibe: Build a rough spike (1-2 hours) → Goal: Prove it works, discover unknowns 2. Reflect: Document what you learned → Edge cases, gotchas, architectural insights 3. Smart: Rebuild properly (with knowledge gained) → Clean architecture, proper error handling, tests 4. Compare: Review spike vs. final implementation → Validate you didn't lose important details Enter fullscreen mode Exit fullscreen mode The spike is intentionally disposable. Its only purpose is to transfer knowledge from "unknown unknown" to "known known." Once that transfer is complete, the spike has served its purpose. Bidirectional Learning: Teaching Your AI Agent Smart Coding isn't just about learning from AI — it's about teaching AI to work better with you. The relationship should be symbiotic: you learn what AI knows better, and AI learns what you know better. The Knowledge File Pattern Create a dedicated knowledge file that your AI agent reads at the start of every session. This file contains: Project architecture decisions and rationale Coding conventions and style preferences Domain-specific terminology and business logic Common pitfalls and their solutions Preferred patterns and anti-patterns Links to key documentation # PROJECT_CONTEXT.md ## Architecture - We use hexagonal architecture with ports/adapters - All external services accessed through interfaces - No business logic in HTTP handlers ## Conventions - Error handling: wrap with context, never naked errors - Logging: structured JSON, always include request_id - Naming: repositories end with "Repo", services with "Service" ## Domain Knowledge - "Settlement" means end-of-day batch processing - "Reconciliation" runs at 03:00 UTC, not local time - Customer IDs are UUIDs, Order IDs are sequential ## Known Pitfalls - Redis cluster doesn't support MULTI in our setup - Legacy API returns 200 for errors, check response body - Date fields from Partner X are in ISO but without timezone ## Preferred Patterns - Use functional options for constructors - Table-driven tests for validation logic - Context propagation through all layers Enter fullscreen mode Exit fullscreen mode What to Teach Your Agent You know better than AI: Your specific project context and history Business domain nuances and edge cases Team conventions and preferences Past mistakes and lessons learned Stakeholder requirements and constraints Performance characteristics of your infrastructure AI knows better than you: Syntax across multiple languages Common algorithm implementations Library APIs and usage patterns General best practices and patterns Boilerplate generation Code transformation and refactoring Building Your Knowledge Base Incrementally Don't try to create a comprehensive knowledge file upfront. Build it through real interactions: Incremental knowledge capture: 1. AI makes a mistake based on missing context 2. You correct it and explain why 3. Add that context to your knowledge file 4. Next session, AI doesn't repeat the mistake Enter fullscreen mode Exit fullscreen mode Example evolution: Week 1: AI suggests time.Now() everywhere You add: "Use injected clock interface for testability" Week 2: AI uses standard logger You add: "Use zerolog with request context" Week 3: AI creates flat package structure You add: "Follow domain-driven package layout: /internal/{domain}/{layer}" Session Priming Start each coding session by having your agent read the knowledge file: "Read PROJECT_CONTEXT.md and acknowledge the key constraints before we start working on the payment reconciliation module." Enter fullscreen mode Exit fullscreen mode This priming ensures AI operates within your established context rather than generic assumptions. The Feedback Loop Smart Coders maintain a continuous feedback loop: ┌─────────────────────────────────────────┐ │ │ │ ┌─────────┐ ┌─────────┐ │ │ │ You │ ←──→ │ AI │ │ │ └────┬────┘ └────┬────┘ │ │ │ │ │ │ ▼ ▼ │ │ ┌─────────────────────────────┐ │ │ │ Knowledge File │ │ │ │ (Shared Context Store) │ │ │ └─────────────────────────────┘ │ │ │ └─────────────────────────────────────────┘ You → AI: Domain knowledge, conventions, constraints AI → You: Patterns, techniques, implementations Both → File: Accumulated project wisdom Enter fullscreen mode Exit fullscreen mode This file becomes a living document — your project's institutional memory that makes every AI session more effective than the last. The Role of Experience Knowing when to Vibe and when to Smart is itself a skill that develops with experience. Junior developers often lack the judgment to know when they're in exploration vs. production mode. They either Vibe everything (accumulating debt) or Smart everything (moving too slowly). Senior developers switch modes fluidly, often within the same coding session. They recognize the smell of "I'm in unknown territory" and permit themselves to Vibe. They equally recognize "this needs to be solid" and engage full Smart rigor. Building This Judgment You can accelerate this learning: Label your modes explicitly. When you start coding, say out loud: "This is a spike" or "This is production code." The explicit labeling builds awareness. Set time boxes for Vibe phases. "I'll explore for 45 minutes, then decide whether to continue or rebuild properly." Review your mode switches. After completing a feature, reflect: Did I switch at the right times? Did I Vibe too long? Did I go Smart too early? Learn from production incidents. Often, bugs trace back to code that should have been Smart but was Vibe'd. These are expensive but effective lessons. The Meta-Skill Ultimately, the ability to choose the right approach for the right context is the meta-skill that separates effective AI-augmented developers from those who are either fighting the tools or being controlled by them. This judgment cannot be automated. It requires: Domain knowledge Understanding of project context Awareness of team capabilities Sense of technical risk Experience with similar decisions AI can accelerate your coding. It cannot replace your judgment about how to code. The Productivity Paradox Vibe Coding appears faster in the short term. Smart Coding is faster in the medium and long term. Timeframe Vibe Coding Smart Coding Hybrid Approach Day 1 Fast Moderate Fast (Vibe spike) Week 1 Fast Moderate Moderate (rebuilding) Month 1 Slowing (debugging) Accelerating Fast (solid foundation + knowledge) Month 6 Struggling (tech debt) Fast Fast Year 1 Rewrite needed Maintainable Maintainable + battle-tested The hybrid approach captures the best of both: rapid initial learning from Vibe, long-term maintainability from Smart. When Pure Vibe Coding is Acceptable Smart Coding isn't dogma. There are legitimate use cases for pure Vibe Coding: Throwaway prototypes : Validating an idea before investing in quality Learning new technologies : Exploring unfamiliar territory (but consolidate later!) One-off scripts : Automation that won't need maintenance Hackathons : Speed matters more than sustainability Feasibility spikes : Proving something is possible before committing The key is intentionality. Choose Vibe Coding consciously for appropriate contexts, not as a default mode. Building Smart Coding Habits Start With Why Before opening your AI assistant, write down: What problem am I solving? What's my success criteria? What are the constraints? Am I exploring or building? Review Rituals Establish a personal review checklist for AI-generated code: [ ] I understand every line [ ] Edge cases are handled [ ] Error handling is appropriate [ ] It follows project conventions [ ] Tests cover the critical paths [ ] No security red flags Knowledge Capture Keep a learning log. When AI teaches you something new, document it. Build your own searchable knowledge base. Over time, you'll rely on AI less for things you've already learned. Mode Awareness Develop the habit of explicitly recognizing which mode you're in: [ ] Is this exploration or production? [ ] Have I time-boxed my Vibe phase? [ ] Am I ready to switch to Smart? [ ] Did I capture learnings from my spike? Conclusion The developers who will thrive in the AI era aren't those who can prompt the fastest. They're the ones who maintain engineering discipline while leveraging AI as a force multiplier — and who know when to break the rules strategically. The Architect Mindset: Your New Role Here's the fundamental shift that Smart Coding demands: you're no longer a junior, mid-level, or even senior developer in the traditional sense. With AI handling implementation details, you must operate as a project architect . From Coder to Architect Traditional career progression looked like this: Junior → Mid → Senior → Lead → Architect ↓ ↓ ↓ ↓ ↓ Tasks Features Modules Systems Vision Enter fullscreen mode Exit fullscreen mode With AI-assisted development, this hierarchy compresses. AI can execute at the junior-to-senior level for implementation tasks. What it cannot do is: Define system boundaries and responsibilities Make technology selection decisions with full context Balance competing stakeholder requirements Anticipate scaling challenges before they emerge Maintain conceptual integrity across the codebase These are architect responsibilities. And now they're yours. The Senior Go Architect Mindset Consider what it means to be a "Senior Go Architect" rather than a "Go Developer": Go Developer Senior Go Architect Writes functions Designs module boundaries Implements features Defines API contracts Follows patterns Selects and adapts patterns Uses libraries Evaluates library tradeoffs Fixes bugs Prevents bug categories Writes tests Designs testing strategy Reads documentation Shapes technical direction When you adopt Smart Coding, you're not asking "how do I implement this?" — you're asking "what should the system look like, and how do the pieces fit together?" Practical Implications Before coding session: Architect's preparation: ☐ What are the system boundaries affected? ☐ What contracts exist with other modules? ☐ What are the failure modes and recovery strategies? ☐ How will this scale? What are the bottlenecks? ☐ What technical debt am I accepting and why? Enter fullscreen mode Exit fullscreen mode During AI interaction: Architect's prompts: - "Given our hexagonal architecture, where should this logic live?" - "What are the tradeoffs between these three approaches for our scale?" - "How would this design impact our deployment strategy?" - "What would need to change if requirements shift toward X?" Enter fullscreen mode Exit fullscreen mode After implementation: Architect's review: ☐ Does this maintain system conceptual integrity? ☐ Are the boundaries clean and the contracts clear? ☐ Would a new team member understand the design intent? ☐ Is the complexity budget spent wisely? Enter fullscreen mode Exit fullscreen mode The Leverage Effect This mindset shift creates extraordinary leverage: Traditional: 1 architect + 5 developers = 6 people output Smart Coding: 1 architect-developer + AI = 10+ people output Enter fullscreen mode Exit fullscreen mode Note: Microsoft and Accenture research (2025) shows 26% average productivity gains for typical AI usage. The Smart Coding approach with architectural thinking delivers multiplicative effects, especially on long-running projects where architecture quality determines overall development velocity. You bring architectural vision and domain expertise. AI brings implementation velocity. The combination is multiplicative, not additive. But this only works if you actually think like an architect. If you remain in "developer mode" — focused on implementation details — you're just a faster typist, not a force multiplier. Becoming the Architect You don't need permission or a title change. Start operating as an architect today: Read architecture books , not just coding tutorials (Clean Architecture, DDD, Fundamentals of Software Architecture) Practice system design — sketch architectures before touching keyboard Study failure cases — post-mortems teach more than success stories Think in boundaries — modules, services, contexts, not files and functions Own technical decisions — document rationale, accept responsibility Mentor the AI — your knowledge file is your architectural vision encoded The title follows the work. Start thinking like a Senior Go Architect, and the AI becomes your implementation team. Final Thoughts Pure Vibe Coding is seductive but unsustainable. Pure Smart Coding can be unnecessarily slow for exploration. The mature approach is hybrid: Vibe to explore, Smart to build, with experience guiding the transitions. Every time you're tempted to accept AI output without understanding, pause and ask: "Am I exploring or building?" If exploring, proceed — but set a time limit. If building, engage your engineering rigor. Remember: AI should make you a faster architect, not a faster typist. Your value is no longer in writing code — it's in knowing what code should exist and why. What ratio works for you: 70/30? 50/50? 90/10? How do you recognize the moment to switch from Vibe to Smart? Share your approach in the comments — I'm curious to compare experiences across different stacks and domains.

Report Abuse Tabassum Khanum Posted on Nov 1, 2021 Server-Side Rendering (SSR) Vs Client-Side Rendering (CSR) # beginners # webdev # javascript # codenewbie Hey Coders! We all can agree that new-age Javascript has changed modern websites structure and the user experience drastically. Websites these days are built more like an application pretending to be a website capable of sending emails, notifications, chat, shop, payments, etc. Today's websites are so advanced, interactive, but earlier, the websites and web applications had a common strategy to follow. They prepared HTML content to be sent to the browsers at the server-side; this content was then rendered as HTML with CSS styling in the browser. Traditionally, the browser receives HTML from the server and renders it. When the user navigates to another URL, a full-page refresh is required and the server sends fresh new HTML for the new page. This is called server-side rendering. Fast forward to today. When websites have 1000s of lines of code to render and with much more complex structures. Today, websites are more than just static pages. The downfall of SSR came when the websites were not all about allowing the user to perform actions and receive a response for their action. That is why developers shifted the ever-growing method of rendering web pages on the client-side. But, here are the questions- Is SSR still relevant? If yes, where to use it. the best approach for you? Server-Side Rendering In SSR, when the user makes a request to the webpage, the server prepares the HTML page by fetching the required data from the database and sends to the user's machine over the internet. Then the browser presents all the requested actions on the user UI. All these processes of fetching data from the database to creating an HTML page and sending it to the client are done in mere milliseconds. This method is viable if all your website need is to display images/ texts, links to click, and is more on the static side. In server-side rendered pages, it is common to use snippets of jQuery to add user interactivity to each page. However, when building large apps, just jQuery is insufficient. After all, jQuery is primarily a library for DOM manipulation and it's not a framework; it does not define a clear structure and organization for your app. Client-Side Rendering Developers are approaching CSR as modern-day development is mostly about JS libraries and frameworks. The popularity of modern-age JS shifted all the attention to CSR. Client-side rendering means that a website’s JavaScript is rendered in your browser, rather than on the website’s server. So now, instead of getting all the content from the HTML doc, only the required HTML with the JS files will be rendered. The rendering time for the first upload is a bit slow. However, the next page loads will be very fast as we don't have to wait for every page render. Moreover, there is no need to reload the entire UI after every call to the server. The client-side framework manages to update UI with changed data by re-rendering only that particular DOM element. Also, a clear client-server separation scales better for larger engineering teams, as the client and server code can be developed and released independently. This is especially so at Grab when we have multiple client apps hitting the same API server. For more clear view let's see some benefits and downside of both rendering methods- Benefits of SSR - The initial page of the website load is faster as there are fewer codes to render. Good for minimal and static sites. Search engines can crawl the site for better SEO. Downsides of SSR - the site interactions are less. Slow page rendering. Full UI reloads. Frequent server requests. Benefits of CSR - The app feels more responsive and users do not see the flash between page navigations due to full-page refreshes. Fewer HTTP requests are made to the server, as the same assets do not have to be downloaded again for each page load. Clear separation of the concerns between the client and the server; you can easily build new clients for different platforms (e.g. mobile, chatbots, smartwatches) without having to modify the server code. You can also modify the technology stack on the client and server independently, as long as the API contract is not broken. Downsides of CSR - Heavier initial page load due to loading of the framework, app code, and assets required for multiple pages. There's an additional step to be done on your server which is to configure it to route all requests to a single entry point and allow client-side routing to take over from there. In most cases, requires an external library. All search engines execute JavaScript during crawling, and they may see empty content on your page. This inadvertently hurts the Search Engine Optimization (SEO) of your app. However, most of the time, when you are building apps, SEO is not the most important factor, as not all the content needs to be indexable by search engines. To overcome this, you can either server-side render your app or use services such as Prerender to "render your javascript in a browser, save the static HTML, and return that to the crawlers". When to use server-side rendering An application has a very simple UI with fewer pages/features An application has less dynamic data Read preference of the site is more than write The focus is not on rich sites and has few users When to use client-side rendering An application has a very complex UI with many pages/features An application has large and dynamic data Write preference of the site is more than reading The focus is on rich sites and a huge number of users The rendering method totally depends on the requirements and the UX plan of the client. The final call is yours whether to use SSR or CSR. I hope this article helped you to understand the basic concepts of rendering practice. Thank You for reading till the end!

Location USA Work Lead Developer & Co-founder at corpscrypt, CTO at REtech Joined Oct 1, 2019 • Nov 2 '21 Dropdown menu Copy link Hide So much to be said here in order to clear up potential misunderstandings for beginners: When deciding which technique to use, the amount of pages is not relevant. If at all, it's the other way around: the more routes your app has, the more likely SSR it the better choice. But let's look at the real why: how important is SEO? If you have an online shop or blog, the answer is probably "very important", as you depend on organic hits. If your app is about user-2-user communication (chats, private communities, etc) then the answer is probably "not so much, as the relevant content is individual. That said, most online shops even with thousands of products usually go for SSR. About history: there wasn't ever a "downfall" of SSR. SPAs simply created a new possibility and this possibly often makes more sense, and often it doesn't. Deciding when to use a fork and when to use a spoon doesn't say anything about whether or not a spoon is better than a fork. In the same way, there isn't any relationship between jQuery and SSR. This must be very confusing to read for the beginner. What OP likely meant was that we didn't have much else historically. But ask yourself why routers are always separate packages in JS frameworks. It's because it's perfectly fine to use Vue or React with SSR. Lastly, we should not forget about the impact technologies like PWA bring to this decision. Fetching and caching sites completely changes pros and cons and considerations to take. There is a huge need for SSR which can be seen when looking at technologies like next, nuxt and co. The truth is that devs tend to prefer CSR for various reasons and therefore are inclined to use it even if it's not the best choice for the task at hand.

This conformance clause. Conformance Requirements and Test Assertions Each normative section defines a single requirement. By enumerating these normative sections, a list of test assertions can be derived. Compliance An implementation is not compliant if it fails to satisfy one or more of the "MUST", "MUST NOT", "REQUIRED", "SHALL", or "SHALL NOT" requirements defined in the normative sections of the specification. Conversely, an implementation of the specification is compliant if it satisfies all the "MUST", "MUST NOT", "REQUIRED", "SHALL", and "SHALL NOT" requirements defined in the normative sections of the specification. Document Statuses Sections and subsections within the specification are marked with statuses indicating their stability level. Functionality described in the specification graduates through these statuses with increasing stability. Stability levels apply only to normative sections within the specification; editorial changes to examples and explanations are exempt from these constraints. It is the responsibility of the Technical Steering Committee to consider and approve the graduation of documents. Possible statuses are described below: Experimental Specification sections that are marked as Experimental contain functionality under active development. Breaking changes are allowed and may be made without deprecation notices or warnings with minor version updates. We recommend you use these features in experimental environments and not in production. Put simply: We're testing these features out. Things could change anytime. Hardening Sections marked as Hardening describe functionality with an emphasis on stabilizing existing requirements. Breaking changes require consensus by the Technical Steering Committee but may still be made with minor version updates. These features are suitable for use in production environments. Feedback is encouraged. Put simply: We believe these features are ready for production use, and hope for feedback. Stable Sections marked as Stable do not allow breaking changes without a major version update. They can be used in production with a high degree of confidence. Put simply: These features are stable and battle-hardened.

Report Abuse Henry Boisdequin Posted on Nov 29, 2020 React vs Vue vs Angular vs Svelte # react # vue # angular # svelte In this article, I'm going to cover which of the top Javascript frontend frameworks: React, Vue, Angular, or Svelte is the best at certain factors and which one is the best for you. There are going to be 5 factors which we are going to look at: popularity, community/resources, performance, learning curve, and real-world examples. Before diving into any of these factors, let's take a look at what these frameworks are. 🔵 React Developed By : Facebook Open-source : Yes Licence : MIT Licence Initial Release : March 2013 Github Repo : https://github.com/facebook/react Description : React is a JavaScript library for building user interfaces. Pros : Easy to learn and use Component-based: reusable code Performant and fast Large community Cons : JSX is required Poor documentation 🟢 Vue Developed By : Evan You Open-source : Yes Licence : MIT Licence Initial Release : Feburary 2014 Github Repo : https://github.com/vuejs/vue Description : Vue.js is a progressive, incrementally-adoptable JavaScript framework for building UI on the web. Pros : Performant and fast Component-based: reusable code Easy to learn and use Good and intuitive documentation Cons : Fewer resources compared to a framework like React Over flexibility at times 🔴 Angular Developed By : Google Open-source : Yes Licence : MIT Licence Initial Release : September 2016 Github Repo : https://github.com/angular/angular Description : Angular is a development platform for building mobile and desktop web applications using Typescript/JavaScript and other languages. Pros : Fast server performance MVC Architecture implementation Component-based: reusable code Good and intuitive documentation Cons : Steep learning curve Angular is very complex 🟠 Svelte Developed By : Rich Harris Open-source : Yes Licence : MIT Licence Initial Release : November 2016 Github Repo : https://github.com/sveltejs/svelte Description : Svelte is a new way to build web applications. It's a compiler that takes your declarative components and converts them into efficient JavaScript that surgically updates the DOM. Pros : No virtual DOM Truly reactive Easy to learn and use Component-based: reusable code Cons : Small community Confusion in variable names and syntax The 1st Factor: Popularity All of these options are extremely popular and are used by loads of developers. I'm going to compare these 4 frameworks in google trends, NPM trends, and the Stackoverflow 2020 survey results to see which one is the most popular. Note: Remember that popularity doesn't mean it has the largest community and resources. Google Trends Google trends measures the number of searches for a certain topic. Let's have a look at the results: Note: React is blue, Angular is red, Svelte is gold, Vue is green. The image above contains the trends for these 4 frontend frameworks over the past 5 years. As you can see, Angular and React are by far the most searched, with React being searched more than Angular. While Vue sits in the middle, Svelte is the clear least searched framework. Although Google Trends gives us the number of search results, it may be a bit deceiving so lets of on to NPM trends. NPM Trends NPM Trends is a tool created by John Potter, used to compare NPM packages popularity. This measures how many times a certain NPM package was downloaded. As you can see, React is clearly the most popular in terms of NPM package downloads. Angular and Vue are very similar on the chart, with them going back and forth while Svelte sits at the bottom once again. Stackoverflow 2020 Survey In February of 2020, close to 65 thousand developers filled out the Stackoverflow survey. This survey is the best in terms of what the actual developer community uses, loves, dreads, and wants. Above is the info for the most popular web frameworks. As you can see React and Angular are 2nd and 3rd but React still has a monumental lead. Vue sits happily in the middle but Svelte is nowhere to be seen. Above are the results for the most loved web frameworks. As you can see, React is still 2nd and this time Vue sits in 3rd. Angular is in the middle of the bunch, but yet again Svelte is not there. Note: Angular.js is not Angular Above are the most dreaded web frameworks. As you can see React and Vue are towards the bottom (which is good) while Angular is one of the most dreaded web frameworks. This is because React and Vue developers tend to make fun of Angular, mostly because of its predecessor Angular.js . Svelte is not on this list which is good for the framework. Explaining Svelte's "Bad" Results Some may say that Svelte performed poorly compared to the other 3 frameworks in this category. You would be right. Svelte is the new kid on the block, not many people are using it or know about it. Think of React, Vue, or Angular in their early stages: that's what Svelte is currently. Most of these frontend frameworks comparisons are between React, Vue, or Angular but since I think that Svelte is promising, I wanted to include it in this comparison. Most of the other factors, Svelte is ranking quite highly in. Wrapping up the 1st Factor: Popularity From the three different trends/surveys, we can conclude that React is the most popular out of the three but with Vue and Angular just behind. Popularity: React Angular Vue Svelte Note: it was very hard to choose between Angular and Vue since they are very close together but I think Angular just edges out Vue in the present day. The 2nd Factor: Community & Resources This factor will be about which framework has the best community and resources. This is a crucial factor as this helps you learn the technology and get help when you are stuck. We are going to be looking at the courses available and the community size behind these frameworks. Let's jump right into it! React React has a massive amount of resources and community members behind it. Firstly, they have a Spectrum chat which usually has around 200 developers looking to help you online. Also, they have a massive amount of Stackoverflow developers looking to help you. There are 262,951 Stackoverflow questions on React, one of the most active Stackoverflow tags. React also has a bunch of resources and tutorials. If you search up React tutorial there will be countless tutorials waiting for you. Here are my recommended React tutorials for getting started: Free: https://youtu.be/4UZrsTqkcW4 Paid: https://www.udemy.com/course/complete-react-developer-zero-to-mastery/ Vue Vue also has loads of resources and a large community but not as large as React. Vue has a Gitter chat with over 19,000 members. In addition, they have a massive Stackoverflow community with 68,778 questions. Where Vue really shines is its resources. Vue has more resources than I could imagine. Here are my recommended Vue tutorials for getting started: Free: https://youtu.be/e-E0UB-YDRk Paid: https://www.udemy.com/course/vuejs-2-the-complete-guide/ Angular Angular has a massive community. Their Gitter chat has over 22,489 people waiting to help you. Also, their Stackoverflow questions asked is over 238,506. Like React and Vue, Angular has a massive amount of resources to help you learn the framework. A downfall to these resources is that most of them are outdated (1-2 years old) but you can still find some great tutorials. Here are my recommended Angular tutorials for getting started: Free: https://youtu.be/Fdf5aTYRW0E Paid: https://www.udemy.com/course/the-complete-guide-to-angular-2/ Svelte Svelte has a growing community yet still has many quality tutorials and resources. An awesome guide to Svelte and their community is here: https://svelte-community.netlify.app . They have a decent Stackoverflow community with over 1,300 questions asked. Also, they have an awesome Discord community with over 1,500 members online on average. Svelte has a lot of great tutorials and resources, despite it only coming on to the world stage quite recently. Here are my recommended Svelte tutorials for getting started: Free: https://www.youtube.com/watch?v=zojEMeQGGHs&list=PL4cUxeGkcC9hlbrVO_2QFVqVPhlZmz7tO Paid: https://www.udemy.com/course/sveltejs-the-complete-guide/ Wrapping up the 2nd Factor: Community & Resources From just looking at the Stackoverflow community and the available resources, we can conclude that all of these 4 frameworks have a massive community and available resources. Community & Resources: React Vue & Angular* Svelte *I really couldn't decide between the two! The 3rd Factor: Performance In this factor, I will be going over which of these frameworks are the most performant. There are going to be three main components to this factor: speed test, startup test, and the memory allocation test. I will be using this website to compare the speed of all frameworks. Speed Test This test will compare each of the frameworks in a set of tasks and find out the speed of which they complete them. Let's have a look at the results. As you can see, just by the colours that Svelte and Vue are indeed the most performant in this category. This table has the name of the actions on one side and the results on the other. At the bottom of the table, we can see something called slowdown geometric mean. Slowdown geometric mean is an indicator of overall performance and speed by a framework. From this, we can conclude that this category ranking: Vue - 1.17 slowdown geometric mean Svelte - 1.19 slowdown geometric mean React & Angular - 1.27 slowdown geometric mean Startup Test The startup test measures how long it takes for one of these frameworks to "startup". Let's see the table. As you can see, Svelte is the clear winner. For every single one of these performance tests, Svelte is blazing fast (if you want to know how Svelte does this, move to the "Why is Svelte so performant?" section). From these results, we can create this category ranking. Svelte Vue React Angular Memory Test The memory test sees which framework takes up the least amount of memory for the same test. Let's jump into the results. Similarly to the startup test, Svelte is clearly on top. Vue and React are quite similar while Angular (once again) is the least performant. From this, we can derive this category ranking. Svelte Vue React Angular Why is Svelte so performant? TL;DR: No Virtual DOM Compiled to just JS Small bundles Before looking at why Svelte is how performant, we need to understand how Svelte works. Svelte is not compiled to JS, HTML, and CSS files. You might be thinking: what!? But that's right, instead of doing that it compiles highly optimized JS files. This means that the application needs no dependencies to start and it's blazing fast. This way no virtual DOM is needed. Your components are compiled to Javascript and the DOM doesn't need to update. Also, it also takes up little memory as it complies in highly optimized, small bundles of Javascript. Wrapping up the 3rd Factor: Performance Svelte made a huge push in this factor, blowing away the others! From the three categories, let's rank these frameworks in terms of performance. Svelte Vue React Angular The 4th Factor: Learning Curve In this factor, we will be looking at how long and how easy it is to be able to build real-world (frontend-only) applications. This is one of the most important factors if you are looking to get going with this framework quickly. Let's dive right into it. React React is super easy to learn. React almost takes no time to learn, I would even say if you are proficient at Javascript and HTML, you can learn the basics in a day. Since we are looking about how long it takes to build a real-world project, this is the list of things you need to learn: How React works JSX State Props Main Hooks useState useEffect useRef useMemo Components NPM, Bebel, Webpack, ES6+ Functional Components vs Class Components React Router Create React App, Next.js, or Gatsby Optional but recommended: Redux, Recoil, Zustand, or Providers Vue In my opinion, Vue takes a bit more time than React to build a real project. With a bit of work, you could learn the Vue fundamentals in less than 3 days. Although Vue takes longer to learn, it is definitely one of the fastest popular Javascript frameworks to learn. Here is the list of things you need to learn: How Vue Works .vue files NPM, Bebel, Webpack, ES6+ State management Vuex Components create-vue-app/Vue CLI Vue Router Declarative Rendering Conditionals and Loops Vue Instance Vue Shorthands Optional: Nuxt.js, Vuetify, NativeScript-Vue Angular Angular is a massive framework, much larger than any other in this comparison. This may be why Angular is not as performant as other frameworks such as React, Svelte, or Vue. To learn the basics of Angular, it could take a week or more. Here are the things you need to learn to build a real-world app in Angular: How Angular Works Typescript Data Types Defining Types Type Inference Interfaces Union Types Function type definitions Two-way data binding Dependency Injection Components Routing NPM, Bebel, Webpack, ES6+ Directives Templates HTTP Client Svelte One could argue that Svelte is the easiest framework to learn in this comparison. I would agree with that. Svelte's syntax is very similar to an HTML file. I would say that you could learn the Svelte basics in a day. Here are the things you need to learn to build a real-world app in Svelte: How Svelte Works .svelte files NPM, Bebel, Webpack, ES6+ Reactivity Props If, Else, Else ifs/Logic Events Binding Lifecycle Methods Context API State in Svelte Svelte Routing Wrapping up the 4th Factor: Learning Curve All these frameworks (especially Vue, Svelte, and React) are extremely easy to learn, very much so when one is already proficient with Javascript and HTML. Let's rank these technologies in terms of their learning curve! (ordered in fastest to learn to longest to learn) Svelte React Vue Angular The 5th Factor: Real-world examples In this factor, the final factor, we will be looking at some real-world examples of apps using that particular framework. At the end of this factor, the technologies won't be ranking but it's up to you to see which of these framework's syntax and way of doing things you like best. Let's dive right into it! React Top 5 Real-world companies using React : Facebook, Instagram, Whatsapp, Yahoo!, Netflix Displaying "Hello World" in React : import React from ' react ' ; function App () { return ( < div > Hello World </ div > ); } Enter fullscreen mode Exit fullscreen mode Vue Top 5 Real-world companies using Vue : NASA, Gitlab, Nintendo, Grammarly, Adobe Displaying "Hello World" in Vue : < template > <h1> Hello World </h1> </ template > Enter fullscreen mode Exit fullscreen mode Angular Top 5 Real-world companies using Angular : Google, Microsoft, Deutsche Bank, Forbes, PayPal Displaying "Hello World" in Angular : import { Component } from ' @angular/core ' ; @ Component ({ selector : ' my-app ' , template : &lt;h1&gt;Hello World&lt;/h1&gt; , }) export class AppComponent ; Enter fullscreen mode Exit fullscreen mode Svelte Top 5 Real-world companies using Svelte : Alaska Air, Godaddy, Philips, Spotify, New York Times Displaying "Hello World" in Svelte : <h1> Hello world </h1> Enter fullscreen mode Exit fullscreen mode Wrapping up the 5th Factor: Real-world Examples Wow! Some huge companies that we use on a daily basis use the frameworks that we use. This shows that all of these frameworks can be used to build apps as big as these household names. Also, the syntax of all of these frameworks is extremely intuitive and easy to learn. You can decide which one you like best! Conculsion I know, you're looking for a ranking of all of these frameworks. It really depends but to fulfil your craving for a ranking, I'll give you my personal opinion : Svelte React Vue Angular This would be my ranking but based on these 5 factors, choose whichever framework you like best and feel yourself coding every day in, all of them are awesome. I hope that you found this article interesting and maybe picked a new framework to learn (I'm going to learn Svelte)! Please let me know which frontend framework you use and why you use it.

But point 4 is subjective depending on your background and previous knowledge. To improve your post, you should add a note explaining what's your background. Finally point 5 are not similar at all. The vue example is a complete page using a reactive property. Anyway as @johnpapa said in a talk, you can achieve almost the same result with any framework, pick the one which feels right for you... :) Like comment: Like comment: 13 likes Like Comment button Reply Collapse Expand Henry Boisdequin Henry Boisdequin Henry Boisdequin Follow Programmer x Swimmer | React Dev, Machine Learning Enthusiast, Rustacean Email boisdequinhenry19@gmail.com Joined Oct 12, 2020 • Nov 29 '20 Dropdown menu Copy link Hide Yes, I agree with you! I would recommend anyone to learn the framework which feels right for you. For the Vue example, I'm not an expert at Vue and don't know a better way to do it (if you have a smaller, more concise 'hello world' example, please comment it). I will definitely work an a 'what's my background section'. To explain it know: I've been using React in all my web dev projects. I have basic knowledge of Vue, Angular, and Svelte. After looking at these 5 factors, I plan to use Svelte for my coming projects. Thanks, @stefanovualto for the feedback!

For the others just plain html. You could have a Vue component with a template of just the h1 tag and no script. It would look more like the svelte example.

Then something similar would be: <template> <h1> Hello world! </h1> </template> Enter fullscreen mode Exit fullscreen mode Maybe a pro' for vue is that it can be adopted/used progressively without having to rely on building process (which I am assuming are mandatory for react, svelte and maybe angular). What I mean is that your previous example worked, but it wasn't comparable to the others.

"Requires JSX" a downside??? I almost stopped reading at that point. Template DSLs are more or less the same. If that's a con, doesn't support JSX could easily be seen as one. There are reasonable arguments for both sides and this shows extreme bias. Vue is "truly reactive" as well. Whatever that means. Your JS Framework Benchmark results are over 2 years old.

When I did some research and asked some other developers when they think of React they think of needing to learn JSX. For something like Svelte, all you need to know is HTML, CSS, and JS. I know that my benchmarks were two years old and I addressed this multiple times before: For the performance factor, I knew that the frameworks were a bit outdated but the general gist stated the same. Svelte 3 was released some time ago and that blows all of the other frameworks out of the water in terms of performance hence Svelte would stay on top. Vue and React are very similar in performance, Vue even says so themselves: vuejs.org/v2/guide/comparison.html. Since, Angular is a massive framework with built-in routing, etc, its performance didn't become better than Vue, React, or Svelte in its newer versions. Thanks for the new benchmark website, I will definitely be using that in the future. Also, I just read your benchmark article and its a good explanation on how these benchmarks work. Thanks for your input.

This is more explanation to that point: Firstly, for confusion in variable names, I'm talking about how Svelte handles state. Coming from React, state would only be initialized with the useState hook. In Svelte, all the variables you make is state which could be confusing for someone just learning Svelte. Also, for the confusion in syntax, I'm talking about the confusion in logic. For example, if statements in Svelte are different than the usual Javascript if statements which could cause some confusion/more learning time for beginners. There are also other examples of this.

A great pro of Svelte is its docs and tutorial on its website. I think in 1-2 years, you are going to see Svelte at least where Vue is in the search trends. Most of the search trends come from developers asking questions like how to fix this error, or how to do this but since not many people use Svelte (compared to the other frameworks) there are not many questions being asked.

Even if Solid completely dominates across the board in all things performance by a considerable margin, we have a long way before popularity, community, or realworld usage really makes it worth even being in a comparison of this nature.

Location Brisbane, Australia Work Founder at kuizto.co Joined Mar 7, 2019 • Dec 4 '20 Dropdown menu Copy link Hide Sorry @hb , you've decided to go on a touchy subject by writing this article! I will have to disagree with you on that point. I think it's perfectly okay to prefer using React. There are many reasons why it is a good choice. However, an easy learning curve isn't part of it. Just so there is no ambiguity, after having used all the Frameworks from this article - my choice goes towards Vue.js and Svelte, but I'll try to remain as objective as possible. 1) According to the State of JS survey 2018 (not using 2019, because that same question wasn't part of last year's survey). From 20,268 developers interrogated, the number #1 argument about Vue.js is an easy learning curve. For React it comes at position #11 (top 3 beings: elegant programming style, rick package ecosystem, and well-established): 2018.stateofjs.com/front-end-frame... 2018.stateofjs.com/front-end-frame... 2) Main reason why Vue.js is labelled "The Progressive JavaScript Framework", is because it is progressive to implement and to learn. Before you can get started with React, you need to know about JSX and build systems. On the other end, Vue.js can be used just by dropping a single script tag into your page and using plain HTML and CSS. This makes a huge difference in terms of approachability of the Framework. 3) Maybe less objective on this one - but from my own professional experience with both Frameworks and leading teams of developers - it usually takes Junior Developers almost twice the time to become proficient with React than with Vue.js. Firstly because of what I mentioned in point number 2. Secondly, because React has few abstraction leaks that makes performance optimisation something developers have to deal with themselves (using memoize hooks). It's a concept that is hard to understand, but essentials if working on large applications. Thirdly, because of the documentation (as you mentioned in your article). And lastly because of the fragmented ecosystem of libraries that can quickly be overwhelming for Junior Devs. Again, I think there are a lot of reasons why React can be a good choice. But not because of the learning curve.

Svelte 3 was released some time ago and that blows all of the other frameworks out of the water in terms of performance hence Svelte would stay on top. Vue and React are very similar in performance, Vue even says so themselves: vuejs.org/v2/guide/comparison.html . Since, Angular is a massive framework with built-in routing, etc, its performance didn't become better than Vue, React, or Svelte in its newer versions. For the search results, they are unpredictable. To my knowledge, there is no new kid on the block in terms of frontend Javascript frameworks. If anything, more people are using Web Assembly. As you can see from the search results graph, it goes up and down, changing all the time.

Coming from React, state would only be initialized with the useState hook. In Svelte, all the variables you make is state which could be confusing for someone just learning Svelte. Also, for the confusion in syntax, I'm talking about the confusion in logic. For example, if statements in Svelte are different than the usual Javascript if statements which could cause some confusion/more learning time for beginners. There are also other examples of this.

Kyle Welch Senior Software Developer at Eventbrite MonoLisa is now my go to font for all places. It has become my expectation in my terminal and code to the point that seeing other fonts confuses me. From the well designed and unique characters make it simple to parse and read throughout the day. Horacio Herrera Independent consultant This font is so sharp that the readability of my code increased a lot! Definitely a font I will use for a long time. Max Stoiber Frontend Developer at Gatsby I love it ♥️ Mark Dalgleish Developer at SEEK I’ve been using MonoLisa as my editor font for the past few months. After a small adjustment period, I really grew to love it. Going back to any of my old font choices feels like a downgrade in comparison. David Khourshid Software developer at Microsoft I’ve been using this font for months, and while the slightly wider nature of this font took a little getting used to at first, it eventually grew on me and I saw how well this font works with my daily workflow. A great, quality font and I highly recommend it! Sara Vieira Engineer at CodeSandbox As someone with an eye condition this font makes my life way easier. And not just in coding but even in design since it doesn’t only carry regular but the whole set of weights so you can even use it in design, logos or anything a monospace font makes sense. Cassidy Williams CTO at Contenda I switched to MonoLisa after trying out several different fonts in my terminal and in my IDE. As a coding instructor and speaker (and just someone who codes a lot in her free time), readability is always the most important thing to me in a font. Kent C. Dodds Making people's lives better with software I’m not much of a font guy, but after using this font for just a few days it’s grown on my and I really like it. (And people wasted no time in constantly asking me what font I use). Two thumbs up 👍👍 Dominik Sumer Co-Founder of seriouscode.io Love the aesthetics of the font and how it improves code readability. That’s why we’ve also decided to use it as the default font at snappify.io Michał Popek Frontend Developer I had been struggling with some vision issues before and MonoLisa really helped me a lot by taking a lot of strain off my eyes. Caleb Porzio Creator of Alpine.js MonoLisa is the perfect coding font IMO. Spacious, stylish, and super readable.

Report Abuse Karun Japhet Posted on Dec 27, 2025 • Originally published at karun.me Efficient logback logging on JVM # java # performance # programming # tutorial Efficient logging that doesn't bring your application down is simple to setup but is often overlooked. Here are some quick tips on how to achieve exactly that Async Logging Most applications these days should have a single (console) appender. This can be linked up with your log aggregator of choice. If your application cannot aggregate logs off the console stream, file is your next best alternative. Wrap each of your appenders with an async appender and add the async appender to your root logger. Every call to the logger creates a log event. In synchronous logging, that log event was processed and writes were made to all appender streams before the application continued. Since most stream writes involve I/O, this meant the application would wait for I/O before continuining thereby slowing it down. With async logging, the event gets pushed to a log level specific in memory queue. These events are processed and consumed by the appenders asynchronously. Since the application can continue after a log event has been published to the queue, asynchronous logging works quicker (as long as I/O is the long pole in the tent that is publishing log messages) Here's a sample configuration: <configuration> <appender name= "FILE" class= "ch.qos.logback.core.FileAppender" > <file> myapp.log </file> <encoder> <pattern> %logger{35} - %msg%n </pattern> </encoder> </appender> <appender name= "ASYNC-FILE" class= "ch.qos.logback.classic.AsyncAppender" > <appender-ref ref= "FILE" /> <queueSize> 1024 </queueSize> <neverBlock> false </neverBlock> </appender> <root> <appender-ref ref= "ASYNC-FILE" /> </root> </configuration> Enter fullscreen mode Exit fullscreen mode Every queue has a configurable depth. The depth of the queue is based on how much memory you have and expected ratio in rates of messages coming in through the application and the messages being published through the I/O bottleneck. If you hit max queue depth on either the WARN or ERROR queues, further statements for those levels become synchronous. If you hit more than 80% of the max queue depth on any other level, the system will start dropping log statements (due to discardingThreshold=20 by default and neverBlock=true ). Therefore, under high load, you can lose INFO , DEBUG and TRACE log messages. This behaviour is acceptable for most cases except specific critical statements (like audit logs). For such cases, you can add asynchronous appenders that are allowed to block. The percentage of depth after which messages are dropped is configurable. You can make info/debug logs synchronous at 100% too if needed by changing the neverBlock=false (which is the default behaviour). All of this information is available on logback’s documentation . Writing log statements Async logs only work more efficiently because the production of events is synchronous (and hopefully a quick task) and the processing of events (which requires IO) is a slow task. However if production of log messages takes long time , async logging will not make things better. When you’re printing a large amount of data or if the creation of the log message is an expensive operation, use the following kind of log statement // style 1: java string interpolation; inefficient and hard to read :P logger . info ( "Large object value was " + largeObject1 + " and long operation printed " + largeObject2 . longOperation ()) // style 2: scala string interpolation; inefficient but easy to read logger . info ( s "Large object value was $largeObject1 and long operation printed ${largeObject2.longOperation()}" ) // style 3: logback based string interpolation; efficient but inconvenient to read logger . info ( "Large object value was {} and long operation printed {}" , largeObject1 , largeObject2 . longOperation ()) Enter fullscreen mode Exit fullscreen mode While the scala interpolation (style 2) is the easiest to read, we should only do it when the objects being printed are small (small-ish strings or primitives). Rule of thumb: For quick statements, use style 2. For large statements, use style 3 (sacrifices readability for efficiency) Never use style 1 :P Using LazyLogging as opposed to creating loggers yourself Use lazy logging . It internally uses loggers that wraps yours code (during compile time) with if checks to not process log statements if the specific log level doesn’t need to be printed ( using macros ). Worried about performance due to extra if conditions? You shouldn’t. Modern processors contain black magic called branch prediction that reduce the effect of statements such as this to be effectively nothing. IMO, every scala project should use lazy logging.

K SDKs Blog GitHub English Português 日本語 한국어 API Documentation Support Home Introduction ATProto Ethos SDKs Glossary FAQ Building apps Quick start Cookbook ⧉ Distributed Systems Guides Overview Identity Data Repositories Schemas & Lexicon Lexicon Style Guide PDS Self-Hosting Going to production OAuth Introduction Permission Requests Account Migration Specs AT Protocol Data Model Lexicon Cryptography Accounts Repository Blobs Labels HTTP API (XRPC) OAuth Permissions Event Stream Sync DID Handle NSID TID Record Key URI Scheme Blobs "Blobs" are media files stored alongside an account's repository. They include images, video, and audio, but could also include any other file format. Blobs are referenced by individual records by the blob lexicon datatype, which includes a content hash (CID) for the blob. Blob files are uploaded and distributed separately from records. Blobs are authoritatively stored by the account's PDS instance, but views are commonly served by CDNs associated with individual applications ("AppViews"), to reduce traffic on the PDS. CDNs may serve transformed (resized, transcoded, etc) versions of the original blob. While blobs are universally content addressed (by CID), they are always referenced and managed in the context of an individual account (DID). The empty blob (zero bytes) is valid in general, though it may be disallowed by individual Lexicons/applications. Blob Metadata Currently, the only "blessed" CID type for blobs is similar to that for repository records, but with the raw multicodec: CIDv1 Multibase: binary serialization within DAG-CBOR (or base32 for JSON mappings) Multicodec: raw (0x55) Multihash: sha-256 with 256 bits (0x12) An example blob CID, in base32 string encoding: bafkreibjfgx2gprinfvicegelk5kosd6y2frmqpqzwqkg7usac74l3t2v4 Blob metadata also includes the size of the blob (in bytes), and the MIME type. The size and CID are deterministic and must be valid and consistent. The MIME type is somewhat more subjective: it is possible for the same bytes to be valid for multiple MIME types. Blob Lifecycle Blobs must be uploaded to the PDS before a record can be created referencing that blob. Note that the server does not know the intended Lexicon when receiving an upload, so can only apply generic blob limits and restrictions at initial upload time, and then enforce Lexicon-defined limits later when the record is created. Clients use the com.atproto.repo.uploadBlob endpoint on their PDS, which will return verified metadata in the form of a Lexicon blob object. Clients "should" set the HTTP Content-Type header and "should" set the Content-Length headers on the upload request. Chunked transfer encoding may also be permitted for uploads. Servers may sniff the blob mimetype to validate against the declared Content-Type header, and either return a modified mimetype in the response, or reject the upload. See "Security Considerations" below. If the actual blob upload size differs from the Content-Length header, the server should reject the upload. After a successful upload, blobs are placed in temporary storage. They are not accessible for download or distribution while in this state. Servers should "garbage collect" (delete) un-referenced temporary blobs after an appropriate time span (see implementation guidelines below). Blobs which are in temporary storage should not be included in the listBlobs output. The upload blob can now be referenced from records by including the returned blob metadata in a record. When processing record creation, the server extracts the set of all referenced blobs, and checks that they are either already referenced, or are in temporary storage. Once the record creation succeeds, the server makes the blob publicly accessible. The same blob can be referenced by multiple records in the same repository. Re-uploading a blob which has already been stored and referenced results in no change to the existing blobs or records. When a record referencing blobs is deleted, the server checks if any other current records from the same repository reference the blob. If not, the blob is deleted along with the record. When an account is deleted, all the hosted blobs are deleted, within some reasonable time frame. When an account is deactivated, takendown, or suspended, blobs should not be publicly accessible. Servers may decide to make individual blobs inaccessible, separately from any account takedown or other account lifecycle events. Creation of new individual records which reference a blob which does not exist should be rejected at the time of creation (or update). However, it is possible for servers to host repository records which reference blobs which are not available locally. For example, during a bulk repository import or account migration; data loss; or content deletion/removal for policy reasons. Original blobs can be fetched from the PDS using the com.atproto.sync.getBlob endpoint. The server should return appropriate Content-Type and Content-Length HTTP headers. It is not a recommended or required pattern to serve media directly from the PDS to end-user browsers, and servers do not need to support or facilitate this use case. See "Security Considerations" below for more. Usage and Implementation Guidelines Servers may have their own generic limits and policies for blobs, separate from any Lexicon-defined constraints. They might implement account-wide quotas on data storage; maximum blob sizes; content policies; etc. Any of these restrictions might be enforced at the initial upload. Server operators should be aware that limits and other restrictions may impact functionality with existing and future applications. To maximize interoperability, operators are recommended to prefer limits on overall account resource consumption (eg, "total blob size" quota, not "per blob" size limits). Some applications may have a long delay between blob upload and reference from a record. To maximize interoperability, server implementations and operators are recommended to allow several hours of grace time before "garbage collecting", with at least one hour a firm lower bound. Security Considerations Serving arbitrary user-uploaded files from a web server raises many content security issues. For example, cross-site scripting (XSS) of scripts or SVG content form the same "origin" as other web pages. It is effectively mandatory to enable a Content Security Policy (LINK: https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP ) for the getBlob endpoint. It is effectively not supported to dynamically serve assets directly out of blob storage (the getBlob endpoint) directly to browsers and web applications. Applications must proxy blobs, files, and assets through an independent CDN, proxy, or other web service before serving to browsers and web agents, and such services are expected to implement security precautions. An example set of content security headers for this endpoint is: Content-Security-Policy: default-src 'none'; sandbox X-Content-Type-Options: nosniff Copy Copied! Some media types may contain sensitive metadata. For example, EXIF metadata in JPEG image files may contain GPS coordinates. Servers might take steps to prevent accidental leakage of such metadata, for example by blocking upload of blobs containing them. See note in "Future Changes" section. Parsing of media files is a notorious source of memory safety bugs and security vulnerabilities. Even content type detection (or "sniffing") can be a source of exploits. Servers are strongly recommended against parsing media files (image, video, audio, or any other non-trivial formats) directly, without the use of strong sandboxing mechanisms. In particular, PDS instances themselves should not directly implement media resizing or transcoding. Richer media types raise the stakes for abusive and illegal content. Services should implement appropriate mechanisms to takedown such content when it is detected and reported. Servers may need to take measures to prevent malicious resource consumption. For example, intentional exhaustion of disk space, network congestion, bandwidth utilization, etc. Rate-limits, size limits, and quotas are recommended. Possible Future Changes The allowed CID type is expected to evolve over time. There has been interest in blake3 for larger file types. More specific mitigation of metadata leakage (eg, EXIF metadata stripping) should be recommended and/or enabled via API changes. There is a tension between providing default safety, and always intervening to manipulate "original" uploaded user data. Additionally, parsing and manipulating uploaded media files raises other categories of security concerns. Previous Repository Next Labels © Copyright 2026 . All rights reserved.

Distribution Docstrings Documentation Exception Handling Functions Generator Expressions Imports Logging Loops Object Mutability Optimization Project Layout Public API Surface Reference Python Glossary / iterable In Python, an iterable is an object that can return its elements one at a time, allowing you to loop over it using a for loop or any other iteration tool. Technically, an iterable must implement the .__iter__() special method which returns an iterator , or implement .__getitem__() to support indexing. Common built-in iterables include lists , tuples , strings , dictionaries , and sets . Iterables form the backbone of Python’s for loops and can be used in list comprehensions , generator expressions , and with the in operator. Unlike iterators , iterables can be traversed multiple times and typically represent a sequence or collection of data that exists in memory. Python Iterable Example Here’s an example that demonstrates how to iterate over a list , which is a common type of iterable: Python >>> fruits = [ "apple" , "banana" , "cherry" ] >>> for fruit in fruits : ... print ( fruit ) ... apple banana cherry In this example, the list fruits is an iterable object, and the for loop iterates over each element, printing it to the console.

What Developers Say Use script variant Gant Laborde CIO at Infinite Red As a consultant, an instructor, and a presenter, having a clean and engaging mono font is paramount, and MonoLisa delivers information perfectly to everyone without forgetting to sneak in some personality in a gentle smile. Kyle Welch Senior Software Developer at Eventbrite MonoLisa is now my go to font for all places. It has become my expectation in my terminal and code to the point that seeing other fonts confuses me. From the well designed and unique characters make it simple to parse and read throughout the day. Horacio Herrera Independent consultant This font is so sharp that the readability of my code increased a lot! Definitely a font I will use for a long time. Max Stoiber Frontend Developer at Gatsby I love it ♥️ Mark Dalgleish Developer at SEEK I’ve been using MonoLisa as my editor font for the past few months. After a small adjustment period, I really grew to love it. Going back to any of my old font choices feels like a downgrade in comparison. David Khourshid Software developer at Microsoft I’ve been using this font for months, and while the slightly wider nature of this font took a little getting used to at first, it eventually grew on me and I saw how well this font works with my daily workflow. A great, quality font and I highly recommend it! Sara Vieira Engineer at CodeSandbox As someone with an eye condition this font makes my life way easier. And not just in coding but even in design since it doesn’t only carry regular but the whole set of weights so you can even use it in design, logos or anything a monospace font makes sense. Cassidy Williams CTO at Contenda I switched to MonoLisa after trying out several different fonts in my terminal and in my IDE. As a coding instructor and speaker (and just someone who codes a lot in her free time), readability is always the most important thing to me in a font. Kent C. Dodds Making people's lives better with software I’m not much of a font guy, but after using this font for just a few days it’s grown on my and I really like it. (And people wasted no time in constantly asking me what font I use). Two thumbs up 👍👍 Dominik Sumer Co-Founder of seriouscode.io Love the aesthetics of the font and how it improves code readability. That’s why we’ve also decided to use it as the default font at snappify.io Michał Popek Frontend Developer I had been struggling with some vision issues before and MonoLisa really helped me a lot by taking a lot of strain off my eyes. Caleb Porzio Creator of Alpine.js MonoLisa is the perfect coding font IMO. Spacious, stylish, and super readable.

This must be understood before executing more trades. Source Early Retirement Now - Why the Wheel Strategy Doesn't Work Six Key Criticisms 1. Ignores Market History Bear markets can last 13+ years (2000-2013) During prolonged downturns, selling calls at original strike generates minimal income Strategy assumes stocks recover quickly - not always true 2. Excessive Leverage Risk Assignment creates margin positions A 30% further decline could "wipe out your entire account" with leverage Our mitigation : We use cash-secured puts only (no margin) 3. Disguised Valuation Betting Strategy inadvertently increases equity exposure as losses mount Shifts from 20 Delta to 100 Delta (full stock ownership) Forces "doubling down" on losing positions Our mitigation : 25% stop loss prevents unlimited losses 4. Mathematical Inconsistency Two identical investors would have vastly different allocations Starting puts vs holding assigned shares = illogical difference Strategy lacks coherent theoretical foundation 5. Enables Fraudulent Reporting YouTube influencers hide unrealized losses Report only "realized" premiums as "returns" Creates misleading 30-60% "return" claims Warning : Be skeptical of YouTube profit claims 6. Requires Superior Stock Picking Assumes you can identify stocks that "can't fall for extended periods" Even "quality" stocks like PTON, RIDE failed Stock picking is not reliable Bogleheads Perspective (Additional Research) From Bogleheads Forum : "This strategy is called eating like a bird and pooping like an elephant. With good reason. If it works, you'll keep leveraging up until you blow out." "For me it's only play money and for a small number of puts." The Bogleheads community is generally skeptical of options selling for income. Impact on Our Strategy What We're Doing Right Cash-secured puts (no margin leverage) Quality stock selection (F, SOFI, T, INTC, BAC, VZ) 25% stop loss (prevents unlimited losses) Small position sizes (10% max per position) What We Need to Address Understand the math : Our 80% win rate with -6.97% avg return proves the criticism - small wins, big losses Don't trust YouTube influencers : Many hide unrealized losses Accept limitations : With $500, we can only do 1 CSP at a time Realistic expectations : This is not a "get rich quick" strategy Recommendations Keep tight stop losses (25%) - already implemented Don't increase position sizes when assigned (avoid doubling down) Diversify - don't put all capital in one wheel trade Track realized AND unrealized P/L honestly Consider alternatives : Credit spreads reduce capital requirements Honest Assessment The wheel strategy CAN work, but: It's not magical passive income It requires discipline and risk management It can lose money in extended bear markets YouTube success stories are often misleading Our current implementation is reasonable with proper risk controls, but we must: Keep expectations realistic Never hide unrealized losses Exit losing positions (don't "wheel" forever hoping for recovery) Tags strategy , wheel , options , risk , research , criticism Prevention Query this lesson before any wheel strategy trade Always report realized AND unrealized P/L Don't trust YouTube "passive income" claims This lesson was auto-published from our AI Trading repository .

Ignores Market History Bear markets can last 13+ years (2000-2013) During prolonged downturns, selling calls at original strike generates minimal income Strategy assumes stocks recover quickly - not always true 2. Excessive Leverage Risk Assignment creates margin positions A 30% further decline could "wipe out your entire account" with leverage Our mitigation : We use cash-secured puts only (no margin) 3. Disguised Valuation Betting Strategy inadvertently increases equity exposure as losses mount Shifts from 20 Delta to 100 Delta (full stock ownership) Forces "doubling down" on losing positions Our mitigation : 25% stop loss prevents unlimited losses 4. Mathematical Inconsistency Two identical investors would have vastly different allocations Starting puts vs holding assigned shares = illogical difference Strategy lacks coherent theoretical foundation 5. Enables Fraudulent Reporting YouTube influencers hide unrealized losses Report only "realized" premiums as "returns" Creates misleading 30-60% "return" claims Warning : Be skeptical of YouTube profit claims 6. Requires Superior Stock Picking Assumes you can identify stocks that "can't fall for extended periods" Even "quality" stocks like PTON, RIDE failed Stock picking is not reliable Bogleheads Perspective (Additional Research) From Bogleheads Forum : "This strategy is called eating like a bird and pooping like an elephant. With good reason. If it works, you'll keep leveraging up until you blow out." "For me it's only play money and for a small number of puts." The Bogleheads community is generally skeptical of options selling for income. Impact on Our Strategy What We're Doing Right Cash-secured puts (no margin leverage) Quality stock selection (F, SOFI, T, INTC, BAC, VZ) 25% stop loss (prevents unlimited losses) Small position sizes (10% max per position) What We Need to Address Understand the math : Our 80% win rate with -6.97% avg return proves the criticism - small wins, big losses Don't trust YouTube influencers : Many hide unrealized losses Accept limitations : With $500, we can only do 1 CSP at a time Realistic expectations : This is not a "get rich quick" strategy Recommendations Keep tight stop losses (25%) - already implemented Don't increase position sizes when assigned (avoid doubling down) Diversify - don't put all capital in one wheel trade Track realized AND unrealized P/L honestly Consider alternatives : Credit spreads reduce capital requirements Honest Assessment The wheel strategy CAN work, but: It's not magical passive income It requires discipline and risk management It can lose money in extended bear markets YouTube success stories are often misleading Our current implementation is reasonable with proper risk controls, but we must: Keep expectations realistic Never hide unrealized losses Exit losing positions (don't "wheel" forever hoping for recovery) Tags strategy , wheel , options , risk , research , criticism Prevention Query this lesson before any wheel strategy trade Always report realized AND unrealized P/L Don't trust YouTube "passive income" claims This lesson was auto-published from our AI Trading repository .

Report Abuse Tabassum Khanum Posted on Nov 1, 2021 Server-Side Rendering (SSR) Vs Client-Side Rendering (CSR) # beginners # webdev # javascript # codenewbie Hey Coders! We all can agree that new-age Javascript has changed modern websites structure and the user experience drastically. Websites these days are built more like an application pretending to be a website capable of sending emails, notifications, chat, shop, payments, etc. Today's websites are so advanced, interactive, but earlier, the websites and web applications had a common strategy to follow. They prepared HTML content to be sent to the browsers at the server-side; this content was then rendered as HTML with CSS styling in the browser. Traditionally, the browser receives HTML from the server and renders it. When the user navigates to another URL, a full-page refresh is required and the server sends fresh new HTML for the new page. This is called server-side rendering. Fast forward to today. When websites have 1000s of lines of code to render and with much more complex structures. Today, websites are more than just static pages. The downfall of SSR came when the websites were not all about allowing the user to perform actions and receive a response for their action. That is why developers shifted the ever-growing method of rendering web pages on the client-side. But, here are the questions- Is SSR still relevant? If yes, where to use it. the best approach for you? Server-Side Rendering In SSR, when the user makes a request to the webpage, the server prepares the HTML page by fetching the required data from the database and sends to the user's machine over the internet. Then the browser presents all the requested actions on the user UI. All these processes of fetching data from the database to creating an HTML page and sending it to the client are done in mere milliseconds. This method is viable if all your website need is to display images/ texts, links to click, and is more on the static side. In server-side rendered pages, it is common to use snippets of jQuery to add user interactivity to each page. However, when building large apps, just jQuery is insufficient. After all, jQuery is primarily a library for DOM manipulation and it's not a framework; it does not define a clear structure and organization for your app. Client-Side Rendering Developers are approaching CSR as modern-day development is mostly about JS libraries and frameworks. The popularity of modern-age JS shifted all the attention to CSR. Client-side rendering means that a website’s JavaScript is rendered in your browser, rather than on the website’s server. So now, instead of getting all the content from the HTML doc, only the required HTML with the JS files will be rendered. The rendering time for the first upload is a bit slow. However, the next page loads will be very fast as we don't have to wait for every page render. Moreover, there is no need to reload the entire UI after every call to the server. The client-side framework manages to update UI with changed data by re-rendering only that particular DOM element. Also, a clear client-server separation scales better for larger engineering teams, as the client and server code can be developed and released independently. This is especially so at Grab when we have multiple client apps hitting the same API server. For more clear view let's see some benefits and downside of both rendering methods- Benefits of SSR - The initial page of the website load is faster as there are fewer codes to render. Good for minimal and static sites. Search engines can crawl the site for better SEO. Downsides of SSR - the site interactions are less. Slow page rendering. Full UI reloads. Frequent server requests. Benefits of CSR - The app feels more responsive and users do not see the flash between page navigations due to full-page refreshes. Fewer HTTP requests are made to the server, as the same assets do not have to be downloaded again for each page load. Clear separation of the concerns between the client and the server; you can easily build new clients for different platforms (e.g. mobile, chatbots, smartwatches) without having to modify the server code. You can also modify the technology stack on the client and server independently, as long as the API contract is not broken. Downsides of CSR - Heavier initial page load due to loading of the framework, app code, and assets required for multiple pages. There's an additional step to be done on your server which is to configure it to route all requests to a single entry point and allow client-side routing to take over from there. In most cases, requires an external library. All search engines execute JavaScript during crawling, and they may see empty content on your page. This inadvertently hurts the Search Engine Optimization (SEO) of your app. However, most of the time, when you are building apps, SEO is not the most important factor, as not all the content needs to be indexable by search engines. To overcome this, you can either server-side render your app or use services such as Prerender to "render your javascript in a browser, save the static HTML, and return that to the crawlers". When to use server-side rendering An application has a very simple UI with fewer pages/features An application has less dynamic data Read preference of the site is more than write The focus is not on rich sites and has few users When to use client-side rendering An application has a very complex UI with many pages/features An application has large and dynamic data Write preference of the site is more than reading The focus is on rich sites and a huge number of users The rendering method totally depends on the requirements and the UX plan of the client. The final call is yours whether to use SSR or CSR. I hope this article helped you to understand the basic concepts of rendering practice. Thank You for reading till the end!

Location USA Work Lead Developer & Co-founder at corpscrypt, CTO at REtech Joined Oct 1, 2019 • Nov 2 '21 Dropdown menu Copy link Hide So much to be said here in order to clear up potential misunderstandings for beginners: When deciding which technique to use, the amount of pages is not relevant. If at all, it's the other way around: the more routes your app has, the more likely SSR it the better choice. But let's look at the real why: how important is SEO? If you have an online shop or blog, the answer is probably "very important", as you depend on organic hits. If your app is about user-2-user communication (chats, private communities, etc) then the answer is probably "not so much, as the relevant content is individual. That said, most online shops even with thousands of products usually go for SSR. About history: there wasn't ever a "downfall" of SSR. SPAs simply created a new possibility and this possibly often makes more sense, and often it doesn't. Deciding when to use a fork and when to use a spoon doesn't say anything about whether or not a spoon is better than a fork. In the same way, there isn't any relationship between jQuery and SSR. This must be very confusing to read for the beginner. What OP likely meant was that we didn't have much else historically. But ask yourself why routers are always separate packages in JS frameworks. It's because it's perfectly fine to use Vue or React with SSR. Lastly, we should not forget about the impact technologies like PWA bring to this decision. Fetching and caching sites completely changes pros and cons and considerations to take. There is a huge need for SSR which can be seen when looking at technologies like next, nuxt and co. The truth is that devs tend to prefer CSR for various reasons and therefore are inclined to use it even if it's not the best choice for the task at hand.

This is important because it ensures that alerts are delivered to users logically and coherently for some sorts of notifications where the order of occurrences is essential. Cost-effective: Kinesis is a cost-effective alternative for applications with high notification quantities. It is a good option for notification systems with high rates of event generation because its price mechanism is compatible with high-throughput scenarios. Security: Strong security features offered by Kinesis include encryption in transit and at rest, granular access control, and interaction with AWS Identity and Access Management (IAM). This guarantees that your notification data is secure and complies with applicable laws and standards. DynamoDB vs. Kinesis Let’s see the difference between DynamoDB and Kinesis. Aspects DynamoDB Kinesis Location Local to DynamoDB, part of the DynamoDB service A standalone service provided by AWS Scope Limited to item-level modifications within a DynamoDB table. Supports streaming and processing of data in any format. IAM Integration Integrated with AWS Identity and Access Management (IAM) Supports fine-grained access control through IAM Cost No additional cost for DynamoDB users Follows a separate pay-per-use pricing model Retention Period Maximum retention period of 24 hours Allows a retention period of up to 7 days Message Ordering Ordered at the item level within a shard Ordered at the shard level Shard Capacity Supports up to 1,000 records per second per shard Maximum capacity of 2,000 records per second per shard Streams per Table Limited to a single stream per DynamoDB table. Supports multiple streams per shard, offering greater flexibility. Throughput High throughput for item-level modifications. High throughput for streaming data. Latency Low latency for reads and writes. Low latency for data processing and delivery. Security Integrated with IAM for access control. Fine-grained access control through IAM. Use Cases Real-time applications, low-latency workloads, small to medium-scale applications with straightforward notification workflows. High-throughput applications, complex notification logic, applications integrated with big data analytics pipelines. Durability Data is replicated across multiple Availability Zones for high durability. Data is replicated across multiple Availability Zones for high durability. Cons of DynamoDB and Kinesis DynamoDB Cons:- Cost: DynamoDB can be pricey, particularly for huge datasets or high throughput. If the expense is not effectively handled, it might rise quickly. Limited Query Capabilities: DynamoDB has fewer query options than conventional relational databases despite being built for high-speed access. Complex querying or analytics jobs may become more difficult as a result. Complexity of Data Modeling: Creating the DynamoDB schema can be challenging, particularly for applications with intricate relationships or a wide range of access behaviors. It necessitates having a solid grasp of the application's requirements. Limited Transaction: Compared to conventional relational databases, DynamoDB offers less support for complicated transactional processes. Limitations of the Global Secondary Index (GSI): GSIs can offer query flexibility but are constrained in consistency and write throughput. AWS Kinesis Cons:- Setup Difficulty: Compared to more straightforward messaging services like Amazon Simple Notification Service (SNS), Kinesis setup and configuration can be more difficult. Requirement for Real-Time Processing: Kinesis is made to process streaming data in real-time. Kinesis could be over-engineered if your use case doesn't call for real-time processing. Shard Management: It can be difficult to control how many shards are in a Kinesis stream. Lack of shard allocation may prevent you from managing the volume of incoming data. Allocating too many shards, however, can be expensive. Limited Retention Period: Data recorded in a Kinesis stream is only kept for a specific amount of time (the default is 24 hours). Implementing more storage will be necessary to save the data longer. No Built-In Notification Mechanism: Notifications cannot be sent using Kinesis without a built-in notification system. You'll need to combine it with other AWS services or develop your own solutions for actual notice delivery. Key Factors to Consider When Choosing Between DynamoDB and Kinesis Some of the critical factors to consider while choosing the right message broker between DynamoDB and Kinesis. Data Structure You must think about the structure of your data and how it should be processed and stored. DynamoDB provides a flexible schema-less database that can handle structured, semi-structured, and unstructured data. If your data is predominantly in a streaming format, Kinesis, on the other hand, maybe a better choice as it is built for processing and analyzing massive volumes of data streams. Scalability To Handle growing data volumes, both DynamoDB and Kinesis provide seamless scaling. However, Kinesis is made for increasing data ingestion and processing capacity, whereas DynamoDB's scalability is concentrated on storage capacity. Consider your expected growth and select a message broker that meets your scalability requirements. Cost Consider your budgetary constraints when comparing the pricing plans for DynamoDB and Kinesis. While Kinesis pricing is mainly based on data ingestion rates and shard (processing unit) utilization, DynamoDB fees are based on provisioned throughput capacity and storage. Analyze your anticipated data volume and processing needs to determine the expenses involved. Use Case Choosing the best message broker requires thoroughly understanding your unique use case. Kinesis can be a better option if your application needs high-speed data ingestion and real-time data streaming. On the other hand, DynamoDB can be the best option if you require a highly scalable NoSQL database with low latency access. Suitability for Notification Services: DynamoDB vs. Kinesis Both DynamoDB and Kinesis are services offered by Amazon Web Services (AWS) that are intended for various use cases and have diverse functions, especially when managing notifications. Choose Amazon Kinesis If: Kinesis works well when quickly processing and evaluating large amounts of streaming data. Kinesis may be a suitable choice if your notification system depends on the real-time processing of massive amounts of data. Data can be ingested and processed in real-time using Kinesis Streams. The data stream can be processed more thoroughly using Kinesis Analytics. Streaming data can be loaded into other AWS services via Kinesis Firehose for additional processing and notification delivery. Choose DynamoDB If: Although DynamoDB isn't made especially to handle notifications, notification systems can be implemented using DynamoDB in conjunction with other AWS services. User preferences, notification history, and other notification-related data can all be stored in DynamoDB. Changes to the data in the database can be captured and processed using DynamoDB Streams, which is helpful in setting off notifications. Kinesis might be a better option if you're creating a notification system that needs to process massive amounts of streaming data in real time. However, DynamoDB can still be used with other AWS services to create a successful notification system if you're seeking a more accessible solution and your notifications don't depend on the real-time processing of massive datasets.

Its building blocks offer flexibility to create engaging messages and add buttons, menus, and media. Diverse events like customer feedback can trigger these transactional notifications, GitHub pull requests or create new database entries. For this blog, we will guide you on how to send transactional notifications on Slack for sending important alerts, updates, and reminders to your users. Slack Block Kit Components Slack Block Kit provides several blocks that can be used to create custom and interactive notifications for Slack. For example, you can use a text block for a heading, an image block for a product screenshot, an action block for a "Approval Request" CTA button, and a context block for the meeting time and location. List of Slack Block Kit Layout Blocks Slack Block Kit uses JSON objects to define the blocks and their properties. Multiple blocks can create more complex, rich, and engaging messages. Different blocks are given below. Section: A block for organizing content into sections, supporting text, images, and buttons. Syntax: Divider: A simple line divider used to visually separate blocks. Syntax: Image: A block for displaying images with support for URLs, alt text, and sizing options. Syntax: Actions: A block for adding interactive elements, such as buttons and menus, to a message. Syntax: Context: A block for providing additional context or supplementary information to a message, with support for images and text. Syntax: Input: A block for collecting user input, with support for various input types like plain text, checkboxes, radio buttons, and more. Syntax: File: A block for displaying information about a file, with support for various file types like images, documents, and videos. Syntax: Creating New JIRA Ticket Notification using Slack Block Kit In this section, we will walk through creating a custom notification ( New Support Request ) using Block Kit components. The following JSON code blocks would be used to create a notification as shown below: Pre-requisites To get started, you would need the following things: A JIRA account with administrative access A Slack account with administrative access Basic knowledge of JIRA and Slack platforms Basic knowledge of JSON and JSONNET A code editor that supports JSON and JSONNET (e.g. VS Code) A webhook URL for Slack integration with JIRA A JIRA project with a webhook URL configured to send notifications to Slack Access to the command line interface (CLI) for installing and using the ‘’’jsonnet’’’ tool You can check JIRA Server integration here: Jira Server | Slack App Directory Step 1: Choose the event that will trigger the notification First, you need to determine the event that will trigger the notification. This could be a new database entry, a user action, or a customer support ticket. Once you know the event, you can create a webhook to send the notification to Slack. In this example, the trigger will come when someone creates a new JIRA ticket. Step 2: Determine the content of the notification Next, you need to determine the content of the notification. It might include text, images, links, and buttons. In this example, we would create a ‘ new support request ’ ticket message to be delivered on Slack. Step 3: Select the Block Kit components Once you know the content you want to include in the notification, you can select the appropriate Block Kit components. In this example, we will use the ‘section,’ ‘image,’ and ‘action’ blocks to create our Slack message. Step 4: Organize the content using layout blocks Once you've selected the components, you must organize them using layout blocks. These blocks control the structure and formatting of the notification. We will use ‘section’, ‘button’, and ‘divider’ blocks in this example. Ensure that the outgoing URL points to your JIRA instance correctly. Step 5: Send the notification Finally, you can send the notification to the appropriate channel or user. You can use the Slack API to send the notification programmatically or use a third-party integration tool, such as Zapier or IFTTT. Here's the ‘ message preview ’ for the above code after sending it. Customizing Notification Content for Each Recipient With Dynamic Fields Using JSONNET Block Kit is an advanced tool that enables personalized notification content for each recipient through the use of dynamic fields. By leveraging JSONNET, you can easily customize templates to include rich elements like text, images, inputs, and more. This guide will show you how to utilize dynamic fields in Block Kit to create highly personalized and relevant notifications. Step 1: Determine the dynamic fields First, determine which fields will differ for each customer. For the JIRA ticket example, use the customer name, ticket subject, ticket description, and the recipient's name to customize the notification message. Step 2: Insert placeholders for the dynamic fields Using JSONNET, construct a message template that includes placeholders for the dynamic fields. Here's an example: Here's a breakdown of the dynamic fields used in this JIRA ticket example: '''{recipient_name} ''': This is a placeholder for the recipient's name. '''{customer_name }''': This is a placeholder for the customer's name who submitted the support request. '''{ticket_subject}''' : This is a placeholder for the subject of the JIRA ticket. '''{ticket_description}''' : This is a placeholder for the description of the JIRA ticket. You can also include additional information about the support request by adding more dynamic fields to the message. Step 3: Use the Slack API to replace the placeholders When you're ready to send the notification, use the Slack API to replace the placeholders with the actual values for each customer. Here's an example of Slack JSON API payload: Note that this example uses plain text formatting. You'll need to use Slack's message formatting syntax to include more advanced formatting, such as bold or italicized text. The placeholders will be replaced with the actual values for each recipient when the notification is sent. You can send this JSON payload using Slack API methods such as '''chat.postMessage''' or '''chat.update'''. Advanced Block Kit customization techniques While Block Kit offers a wide range of components to create custom notifications, more advanced techniques can be used to customize the notifications further. This section will discuss some advanced Block Kit customization techniques, such as using modals to collect user input or creating custom Block Kit components. Using modals to collect user input Modals are pop-up windows that can be used to collect user input, and they are a great way to streamline workflows and improve the user experience. In Slack, you can use the views.open method of the Slack API to create modals with custom content. Here's an example of a modal that asks the user to confirm an action. This code will create a simple modal with a title, a confirmation button, a cancel button, and a single section block that displays a message to the user. Creating custom Block Kit components: Block Kit provides a wide range of pre-built components that you can use to create custom notifications, but sometimes you may need to create your own. To do this, you can use the blocks array in your message payload and define the custom component using the JSON schema. In this example, we define a custom component with the type of " custom " and a Custom component value " data value. We then include this custom component in the blocks array of the message dictionary. Finally, we create a payload dictionary that includes the text and blocks fields, and we convert this dictionary to a JSON string using the json module's dumps function. Remember that the JSON schema for custom components may vary depending on the specific component you want to create. Using the Block Kit Builder tool: Creating custom notification templates using Block Kit and JSONNET can be complex, especially if you're unfamiliar with JSONNET or the Slack API. Slack offers a tool called the Block Kit Builder to simplify the creation of custom notifications, but you will need to use JSONNET to create and render notification templates. Customizing Transactional Notifications with Block Kit Best Practices Customizing transactional notifications using Block Kit can be a powerful way to improve user engagement and streamline workflows. However, it's important to follow best practices to ensure your custom notifications are effective and reliable. Here are some tips: Use consistent branding : Custom notifications should reflect your brand identity and be consistent with your other messaging. Use your brand colors, fonts, and tone of voice to make your notifications instantly recognizable. Keep the layout simple : Avoid cluttering your notifications with too much information or components. Keep the layout simple and easy to read, and use components only when they add value to the notification. Test your notifications : Before deploying your custom notifications, it's important to test them thoroughly to ensure they work as expected. Use Slack's API or third-party tools like Postman to test your notifications and ensure they deliver the correct information. Handle errors and retries : Transactions can fail for various reasons, such as network issues or invalid user input. Handling errors and retries is important to ensure that notifications are delivered reliably. Use the retry logic provided by Slack's API, and make sure to handle errors gracefully and provide clear instructions to the user. Personalize notifications : Use JSONNET to add dynamic variables in the notifications. This is necessary to do when you are personalizing the notification content for each recipient. Monitor performance : Keep an eye on the performance of your custom notifications and use analytics tools to track engagement and user behavior. This can help you identify areas for improvement and optimize your notifications over time.

Report Abuse Brian Zavala Posted on Jan 13 I made a Meme Creator because I hate watermarks # opensource # javascript # react # webdev I wanted to make a quick meme for my son Phoenix, but every site I found was a disaster. They either demanded a monthly subscription, forced me to create an account, or slapped a giant watermark over the image. I realized that simple tools have become ad-farms. So, I spent the last 3 weeks building my own. My requirements were simple: No Server Uploads: 100% Client-side. No Watermarks: Just clean export. Local AI: Background removal running in the browser. The Stack: React 19 + ONNX I decided to over-engineer this to learn the new React 19 features. Here is the architecture: Frontend: React 19 (using the new use hook for async resource loading). AI Engine: onnxruntime-web + imgly. State Management: 100% Native React 19 (useReducer + Context). No external state libraries. OS: Built entirely on Arch Linux (Hyprland). How the Local AI Works The hardest part was getting the background removal to feel instant without killing the browser tab. I'm using a quantized ONNX model that runs in a Web Worker to keep the UI thread smooth. Here is a snippet of how I handle the image processing: JavaScript import { removeBackground } from " @imgly /background-removal"; export const processImage = async (imageSrc) => { // This runs entirely in the browser using WebAssembly // No data is ever sent to a server const blob = await removeBackground(imageSrc, { progress: (key, current, total) => { console.log( Downloading AI Model: ${key} (${current}/${total}) ); }, model: "medium", // Balances speed vs accuracy }); return URL.createObjectURL(blob); }; Source Available (AGPLv3) I believe in transparency, especially for privacy tools. The code is Source Available under the AGPLv3 license. You can look at the repo to verify that no network requests are sending your photos to a cloud server. I'm Launching on Friday! This is my first real "product" launch. I'm shipping it on Product Hunt this Friday, but the app is live right now for testing.

For enthusiasts of Stacked Pull Requests, this release is a game-changer. We're excited to announce comprehensive support for Graphite , integrating its most powerful features directly into Tower. You can now handle your stacked branches and craft Pull Requests seamlessly within our Git client ✌️ With our Tower 8.0 update , we set the stage for incorporating advanced Git workflows. Features like Branch Dependency and the "Restack" action were introduced, and the response from our user community has been overwhelmingly positive. Building on that foundation, Tower 10 now offers full support for Graphite's toolset, empowering you to merge changes into your projects faster than ever. This article will guide you through the essentials of Graphite and how it integrates with Tower 10. About Graphite If you want to enhance your team's Pull Request process and are unfamiliar with Graphite , you're in for a treat! Graphite employs a stack-based methodology that allows developers to work on several features in parallel by layering changes. This is often called the Stacked Pull Requests workflow . The idea is straightforward: by linking smaller, incremental Pull Requests, you reduce the amount of code to be reviewed. This leads to quicker integration and minimizes the chances of significant merge conflicts or bugs. Effective branch management is key to this approach, and this is where Graphite excels. Even if you are the sole user of this workflow in your team, it works flawlessly from the get-go. There's every reason to give it a shot! 😉 Graphite not only simplifies branch management but also provides a dedicated interface for code reviews (be sure to check out AI Reviews !) and complements GitHub by extending its functionality. In addition to its Web UI, Graphite provides: A CLI tool A VS Code extension You can discover more about Graphite in this article . We believed that integrating these capabilities into a Git client would be a great advantage, so we went ahead and did just that. Let's start the tour! Setting Up Graphite in Tower 10 To begin, simply click the "Workflows" button in the toolbar and select the new Graphite.dev entry. You will need a Graphite.dev account and the Graphite CLI tool (version 1.5.3 or higher) installed. Tower 10 – Enabling the Graphite Workflow ☝️ You may find the "Configure Workflow" button greyed out if you haven't configured Graphite yet. Make sure you install the CLI tool and configure the Graphite token by accessing Tower's terminal ("File -> Open in Terminal"). You'll be asked to specify the "Trunk" branch (typically main ) and your Graphite token , which should be detected automatically by Tower. We recommend installing the Graphite binary via npm , the standard package manager for Node.js. You'll notice the "Workflows" icon has changed to Graphite. Clicking it gives you quick access to popular Graphite commands and opens the Graphite dashboard in your browser. Tower 10 – Graphite Workflow in Toolbar Working with Graphite in Tower 10 Now is a great time to explore the Graphite commands you can run effortlessly in Tower! Working Copy With the Graphite workflow active, you'll see new options in the "Working Copy" view. We've introduced a "Create" action that lets you instantly make a new branch with your staged changes (equivalent to gt create in the Graphite CLI). This is a best practice in the Graphite workflow, which recommends treating each branch as a small, atomic changeset with a single commit initially. The "Commit" action is similar to the gt modify --commit command in Graphite: it adds a new commit to the current branch and automatically restacks if there are no conflicts. Tower 10 — "Working Copy" view ☝️ Tower's "Quick Amend" feature is also compatible with the Graphite workflow. To amend the current branch's commit, hold down ( Left Alt + CTRL ), and the "Commit" button will change to "Modify". This is the same as running gt modify in the Graphite CLI. Creating a Stacked Branch Graphite is centered around Stacked Branches, and creating a new one is simple: right-click on any branch to create a new stacked branch based on it. Tower 10 — Create New Stacked Branch In the following dialog, you can choose its parent branch for straightforward integration and opt to check it out right away. Tower 10 — Create New Stacked Branch Dialog From the context menu, you can also perform all other standard Graphite operations, like renaming, merging, squashing, or deleting branches. Tower 10 – Additional Context Menu Options Setting the Parent Branch You can change a branch's parent at any time, just as you would with Stacked Branches, by using the context menu and selecting "Track Parent Branch." In Graphite's terminology, this is known as "tracking" ( gt track ) and "untracking" ( gt untrack ) a stacked branch. Tower 10 – Setting the Parent Branch Restacking Restacking syncs all changes by rebasing each child branch onto its parent. Tower shows an icon in the sidebar for branches that need restacking. You can perform this action by right-clicking the branch and choosing "Restack [Branch]". In the branch's history, a yellow banner will also inform you that the branch needs to be restacked. Tower 10 — Restack Branch In the "Restack Branch" dialog, you'll see a "Restack Full Stack" option. If this is not checked, Tower/Graphite will restack the selected branch and its parents. If checked, the branch's children will also be restacked (hence "full stack"). Tower will let you know if any conflicts occur during the restack. Tower 10 — Restack Branch Dialog Syncing a Branch Right-clicking any branch also lets you "sync" it. This synchronizes all branches in the stack, much like the gt get command. Tower 10 — Sync Branch Dialog Tower also offers extra options, like restacking all branches in your repository. Submitting a Branch (To Create a Pull Request) You can submit a branch to create a PR by right-clicking it and selecting the option from the context menu. More options are available by clicking the drop-down arrow, such as updating only branches with existing open PRs. Tower 10 — Submit Branch to Graphite All open Pull Requests are accessible in Tower's "Pull Requests" view, in the sidebar or via the shortcut CTRL + 4 . Tower 10 — Pull Requests This view lets you inspect, merge, close, comment on, or check out pull requests without opening a browser. Merge Queue Graphite includes a Merge Queue feature that avoids semantic merge conflicts by automating the rebase process during merges. This keeps the trunk branch "green" and helps development teams move faster with fewer interruptions. In Tower, if a merge is possible, the Graphite branch is added to the merge queue. The merge is asynchronous, so you'll need to manually refresh and sync the branch to see if it has been merged. When a Graphite branch is sent to the merge queue, it's validated remotely. If it can be merged, it is; otherwise, the process fails. To do this, right-click the branch and choose "Add [BRANCH] to Merge Queue…" from Tower's context menu. Tower 10 — Graphite's Merge Queue Warning Messages While using Tower, you might accidentally disrupt Graphite's state with certain Git operations, like a git push . Tower will warn you when this might happen before you proceed. Tower 10 — Warning Message You can enable or disable these prompts in the "Integration" tab of Tower's Settings. Tower 10 — Integration Settings Other Improvements As always, we've also made some other improvements under the hood. Here's a list of the improvements and bug fixes we've addressed: System Menu: The Alt + SPACE shortcut now works as expected. Submodules: Navigation through nested submodules has been refined. Portable Git has been updated to version 2.51.2 for improved compatibility and performance. We hope you enjoy this release! Happy stacking! 😊 Not a Tower user yet?

Report Abuse Aman Saxena Posted on Dec 12, 2025 The Unique Insight Behind the Binary Tree Maximum Path Sum (LeetCode 124) # algorithms # leetcode # programming # software Some coding interview problems feel routine… and then there are the ones that make you pause, sketch ideas, rethink your assumptions, and finally smile when the solution clicks. For me, Binary Tree Maximum Path Sum was exactly that kind of problem. It’s elegant. It’s tricky at first glance. And it teaches a powerful pattern used in many advanced tree problems. If you're preparing for interviews or simply enjoy algorithmic puzzles, this one is worth mastering — and here’s why. Problem Link LeetCode 124 — Binary Tree Maximum Path Sum Why This Problem Stood Out to Me Most tree problems ask you to compute something simple like height, depth, or sum. But this one forces you to think differently: A valid path doesn’t have to start at the root A path can end anywhere A path can go left → root → right, but cannot split upward Sometimes the best path doesn’t even include the root This combination makes the problem feel like a puzzle with multiple layers. The “Aha!” moment is when you realize: Each node must return the best one-sided path upward… but we must also track the best two-sided path that might pass through it. Once this idea settles in, the recursion becomes surprisingly clean. Putting It All Together With Examples Once you understand the idea of one-sided paths and two-sided paths, the problem becomes much more intuitive. Here are a few examples that illustrate exactly how the recursion behaves and why the algorithm works. Example 1 — The Classic “V” Shape Path 1 / \ 2 3 Enter fullscreen mode Exit fullscreen mode At node 1: Best path going upward: max(2, 3) + 1 = 4 Best through this node: 2 + 1 + 3 = 6 Maximum Path Sum = 6 Example 2 — When Negatives Force Interesting Choices -10 / \ 9 20 / \ 15 7 15 → 20 → 7 Enter fullscreen mode Exit fullscreen mode At node 20: one-sided upward path: 20 + max(15, 7) = 35 two-sided local path: 15 + 20 + 7 = 42 ← candidate answer The global maximum becomes 42, even though the root is negative. Example 3 — Best Path Doesn’t Always Linear 5 / \ 4 8 / / \ 11 13 4 / \ \ 7 2 1 7 → 11 → 4 → 5 → 8 → 13 Enter fullscreen mode Exit fullscreen mode Sum = 48 All Negative Values -8 / \ -3 -6 / \ -9 -2 Enter fullscreen mode Exit fullscreen mode Sum = -2 The Core Idea Behind the Solution Once you look at enough examples, the entire problem boils down to just two questions at every node: What is the best path I can send upward? This must be one-sided (left → node or node → right). one_sided = node.val + max(left_gain, right_gain) Enter fullscreen mode Exit fullscreen mode But if a side is negative, we drop it: left_gain = max(dfs(left), 0) right_gain = max(dfs(right), 0) Enter fullscreen mode Exit fullscreen mode What is the best path that passes through this node? This is where both sides can be used: two_sided = left_gain + node.val + right_gain Enter fullscreen mode Exit fullscreen mode This value updates the global maximum — but we never return it upward. That’s the whole trick. Final Solution /** * Definition for a binary tree node. * struct TreeNode { * int val; * TreeNode *left; * TreeNode *right; * TreeNode() : val(0), left(nullptr), right(nullptr) {} * TreeNode(int x) : val(x), left(nullptr), right(nullptr) {} * TreeNode(int x, TreeNode *left, TreeNode *right) : val(x), left(left), * right(right) {} * }; */ class Solution { public: int helper(TreeNode* root, int& maxVal) { if (!root) { return 0; } int leftPath = helper(root->left, maxVal); int rightPath = helper(root->right, maxVal); int pathVal = root->val + max(0, leftPath) + max(0, rightPath); maxVal = max(pathVal, maxVal); return root->val + max(max(0, leftPath), max(0, rightPath)); } int maxPathSum(TreeNode* root) { if (root == NULL) { return 0; } int maxVal = INT_MIN; helper(root, maxVal); return maxVal; } }; Enter fullscreen mode Exit fullscreen mode Top comments (0) Subscribe Personal Trusted User Create template Templates let you quickly answer FAQs or store snippets for re-use.

Deep learning methods are representation learning methods with multiple levels of representation, obtained by composing several simple but non-linear modules that each transform the representation at one level (starting with the raw input) into a representation at a higher, slightly more abstract level - to put it simply - Neural Networks. With the composition of enough such transformations, very complex functions can be learned - a universal approximator.

Report Abuse Nočnica Mellifera Posted on Sep 30, 2025 Filling Out Forms with Playwright: Choosing Between `fill()` and `pressSequentially()` # playwright Filling out forms is one of the most common tasks in web automation and testing. When using Playwright, you have two primary methods for entering text into input fields: .fill() and .pressSequentially() . While both accomplish the same basic goal, choosing the right method can significantly impact the stability, realism, and effectiveness of your tests. The Default Choice: locator.fill() For most scenarios, locator.fill() should be your go-to method. It's fast, efficient, and simulates what happens when a user pastes text into a field. When to use fill() : Simple text inputs without dynamic behavior When you need to quickly populate form fields For basic form submissions where typing simulation isn't critical // Simple and efficient for most cases await page . locator ( ' #username ' ). fill ( ' testuser ' ); await page . locator ( ' #email ' ). fill ( ' user@example.com ' ); Enter fullscreen mode Exit fullscreen mode When to Switch to pressSequentially() The community discussion reveals several specific scenarios where pressSequentially() becomes necessary: 1. Testing Auto-complete and Search Suggestions If you're searching for "Doug Bowser" and want to test the intermediate suggestions that appear as you type "D", "Do", "Dou", etc., fill() won't trigger these incremental updates. // Triggers search suggestions at each keystroke await page . locator ( ' #search ' ). pressSequentially ( ' Doug Bowser ' , { delay : 100 }); Enter fullscreen mode Exit fullscreen mode 2. Triggering Field Validations Some forms validate input as users type. If you need to test this real-time validation behavior, pressSequentially() allows you to simulate the actual typing process that triggers these validations. 3. Making Automation Less Detectable When scraping or performing long-running automation tasks, instantaneous text entry can be a telltale sign of bot activity. pressSequentially() with appropriate delays can help mimic human typing patterns. // More human-like typing behavior await page . locator ( ' #message ' ). pressSequentially ( ' Hello, this is a longer message ' , { delay : 50 // milliseconds between keystrokes }); Enter fullscreen mode Exit fullscreen mode You could even randomize these delay times for multiple form fills. 4. Testing Learning Applications For applications that grade typing velocity and accuracy, or any scenario where the timing and sequence of keystrokes matter, pressSequentially() is clearly the right choice. Practical Recommendations Based on the community consensus: Start with fill() - It's faster and sufficient for most cases Switch to pressSequentially() when you need: To trigger intermediate API calls or UI updates To test real-time validation More realistic user behavior simulation To avoid detection in scraping scenarios Use the delay option to control typing speed when realism matters: await page . locator ( ' #input ' ). pressSequentially ( ' text ' , { delay : 100 }); Enter fullscreen mode Exit fullscreen mode Conclusion While fill() will handle most of your form-filling needs efficiently, pressSequentially() is your tool for scenarios requiring realistic typing behavior. The key is understanding your application's behavior and choosing the method that best matches how real users interact with your forms. Whether you're testing search suggestions, form validations, or simply trying to make your automation more human-like, having both methods in your Playwright toolkit ensures you can handle any form-filling scenario effectively.
