Developers can now achieve more complex functionalities while writing less code. JavaScript, being the default language of the web, has several frameworks available that make web development faster. Getting familiar with these JavaScript frameworks is important to know which framework best suits your next project. React, Angular, Vue, and Svelte are some of the most popular JavaScript frameworks; this article will focus on Angular vs Svelte. Let’s dive into how they compare and which projects they suit best. To properly understand this blog post, you need to have a basic knowledge of the following: - [HTML](https://developer.mozilla.org/en-US/docs/Web/HTML) - [CSS](https://developer.mozilla.org/en-US/docs/Web/CSS) - [JavaScript](https://developer.mozilla.org/en-US/docs/Web/JavaScript) ## Overview of Svelte [Svelte](https://svelte.dev/) is a JavaScript framework that can be used to build a full-scale application or small bits of other applications. The core principle of Svelte is based on running the code at compile time; this is different from frameworks like [React](https://code.pieces.app/blog/react-18-a-comprehensive-guide-to-the-latest-features-and-updates) and [Vue](https://vuejs.org/), which perform most of the operations in the browser while the app is running without a virtual DOM. This makes developing Svelte applications faster, bundles smaller, and performance better. Svelte is also easier to write and learn. It basically entails coding in HTML, CSS, and JavaScript with the addition of a few extensions. However, Svelte has a framework called [SvelteKit](https://kit.svelte.dev/) which allows the implementation of more complex functionalities and features such as routing and server-side rendering. The main features of Svelte include: - **Compile-Time Approach**: A distinct feature of Svelte, especially in comparison to other frameworks, is that it does most of the work at compile time. This is noticeably different from Angular, which does most of the work in the browser. The compile-time approach of Svelte allows the development of more performant applications with smaller bundle sizes. - **Reactive Programming**: Svelte adopts reactive programming, a declarative programming paradigm that uses asynchronous programming to process and update an application’s UI. This makes state management easier. - **No Virtual DOM**: Due to the compile-time approach, Svelte does not use a virtual DOM (as is the case for frameworks like React and Vue) to update the DOM. It manipulates the DOM directly after the code has been compiled. - **Built-in State Management**: Unlike frameworks that use libraries to manage a component’s state, Svelte has built-in state management, making it easier to manage states across different components in the application. ## Overview of Angular Developed by Google, [Angular](https://angular.io/) is a JavaScript framework used for building scalable and efficient single-page applications (SPA). It adopts the [Model-View-Controller (MVC)](https://developer.mozilla.org/en-US/docs/Glossary/MVC) architecture, which separates the application functionality into user interfaces, data, and logic. This separation allows for maximum scalability when developing complex applications. Angular is built with TypeScript, which allows features such as type-checking and ensures more structured development. The features of Angular include: - **Model-View-Controller (MVC) Architecture**: Angular is built on the MVC design pattern which allows for maximum scalability when building modern web applications. Thanks to the MVC architecture, Angular adopts a two-way data-binding approach that provides a seamless synchronization between the model (data) and the view when an update is made. - **TypeScript Support**: Angular supports TypeScript because it’s built with the language, resulting in the development of clean, well-structured, maintainable code. - **Dependency Injection**: Unlike Svelte, Angular has built-in support for dependency injection, which allows the development of more efficient and modular applications. - **Improved Modularity**: Angular allows you to organize your codebase into modules, which provides an easier way to develop, manage, test, and deploy your applications. ## Differences between Svelte and Angular The major difference between Svelte vs Angular is how they each run code in an application. Svelte does most of the work at compile time while Angular does most of the work in the browser. Also, Angular follows an MVC architecture in developing an application while Svelte follows a reactive system app. ## Comparison of Angular, Svelte In this section, we’ll take a deep dive into a detailed comparison of both frameworks, easing your decision of the framework that suits your project best. This comparison will cover diverse criteria such as syntax, working principles, performance, size, active community, ease of learning, and predicted relevance. ### Syntax When learning a new language or framework, a crucial factor is its syntax. In this section, we’ll take a quick look at the syntax of Svelte and Angular by finding the sum of two numbers in both frameworks. Here’s how we’ll get the sum of two numbers in Svelte: ``` <script> let firstNumber = 0; let secondNumber = 0; let sum = 0; function calculateSum() { sum = Number(firstNumber) + Number(secondNumber); } </script> <input type="number" bind:value={firstNumber} placeholder="Enter first number"> <input type="number" bind:value={secondNumber} placeholder="Enter second number"> <button on:click={calculateSum}>Calculate Sum</button> <p>The sum of {firstNumber} and {secondNumber} is {sum}</p> ``` [Save this code](https://jamesamoo.pieces.cloud/?p=346e47bc99) Here, we see Svelte’s syntax is similar to Vanilla JavaScript. We create a function in the `<script/>` tag to find the sum of both numbers and then display the result using a `<p>` tag after the user has given the input for two numbers. Overall, this simple Svelte code snippet displays a user interface that takes in two numbers and gives the sum as output. Here’s how we’ll get the sum of two numbers in Angular: ``` import { Component } from '@angular/core'; @Component({ selector: 'app-root', template: ` <input type="number" [(ngModel)]="num1" placeholder="Enter first number"> <input type="number" [(ngModel)]="num2" placeholder="Enter second number"> <button (click)="addNumbers()">Add</button> <p>Result: {{ result }}</p> ` }) export class AppComponent { firstNumber: number = 0; secondNumber: number = 0; result: number = 0; addNumbers() { this.result = this.firstNumber + this.secondNumber; } } ``` [Save this code](https://jamesamoo.pieces.cloud/?p=6c6d428363) Here, we start by importing the `Component` decorator from Angular and then creating a component class `AppComponent` which contains the function for the logic. The logic to display the UI goes into the template box of the class component. ### Performance and Speed When dealing with web applications, aiming for maximum speed and performance is hugely important. Waiting an extra second for a page to load can be annoying. This is why we, as developers, must make a conscious effort to build highly performant applications. Many factors affect an application's speed such as bundle size, complexity of the code, server performance, etc. We must consider all of these when picking between Angular, React, Vue, Svelte, or another framework. Concerning the performance and speed of an application for Svelte vs Angular, Svelte offers an environment for faster applications due to its smaller bundle size and the fact that it compiles the code at build time. However, when dealing with large and complex applications, Angular provides the necessary support and tooling to build performant applications. ### Size and Optimization Bundle size refers to the total size of a library that contains all the assets needed to run optimally. The bundle size of a library directly affects the speed of an application. Packages go through a process called [minification](https://en.wikipedia.org/wiki/Minification_(programming)) which means removing all unnecessary files from an application without affecting its functionality in a bid to reduce the bundle size. Svelte has a minified bundle size of about **6.8kb** while Angular has a minified bundle size of about **180kb**, which makes Svelte significantly lighter than Angular. However, both frameworks are well-optimized and will work efficiently under the right conditions. ### Learning Curve Another important criterion when learning a new framework is its ease of learning. Whether or not a language or framework’s learning curve is steep affects a developer’s productivity, especially in the early stages. When comparing Svelte vs Angular vs React, frameworks with a gentle learning curve are generally preferred. Coming from a JavaScript background with no prior experience with JavaScript frameworks, Svelte is easier to learn since it’s almost literally writing JavaScript. In fact, Svelte is one of the easiest JavaScript frameworks to learn. So, if you’re keen on learning a framework that has a gentle learning curve, then Svelte is for you. ### Community Support Have you ever been stuck or faced with a bug for a long time, searched for a solution on the internet, and easily found it? Oh, the joy! That’s the power of community support. The larger the community, the easier for developers to get past bugs and solve other problems when using that framework. At the time of this writing, Svelte has over [76,000 stars](https://github.com/sveltejs/svelte) on GitHub and over 680 contributors. Angular, on the other hand, has over [94,000 stars](https://github.com/angular/angular) on GitHub and over 1900 contributors. Both frameworks have fairly large active communities, but Angular has a more mature community base, considering it’s older than Svelte. ### Predicted Relevance Are you comparing Angular vs React vs Vue vs Svelte but you’re worried these frameworks might not be relevant in the next 4-5 years? Well, don’t! Thanks to their immense relevance in the world of web development, Svelte and Angular will likely be here for a very long time and are definitely worth learning. According to NPM, Svelte has over [1 million weekly downloads](https://www.npmjs.com/package/svelte) while Angular has over [3 million weekly downloads](https://www.npmjs.com/package/@angular/core). This confirms both frameworks are fast-growing and should stand the test of time. ## Benefits and Shortcomings of Svelte vs Angular In this section, we will discuss the benefits and shortcomings of both frameworks, further helping you choose your preferred framework. ### Benefits of Svelte - Lightweight and fast due to the compile-time approach - Easy to learn - Easy to manage states across components with its built-in state management feature - Supports Server-Side Rendering (SSR) - Has no dependencies, so your application is less prone to vulnerabilities ### Shortcomings of Svelte - A small developer community makes it harder to find resources, libraries, and other helpful tools - Compared to Angular, it is not well suited to large-scale applications ### Benefits of Angular - Well-suited for building large-scale applications - Large and active developer community - Provides seamless TypeScript support - Built-in testing support - Due to its modular structure, large codebases are easy to organize and maintain. ### Shortcomings of Angular - Relatively steep learning curve. - Larger bundle size due to the injection of various dependencies - Relies on some third-party libraries to run, which can lead to complexities in codebases or compatibility when migrating to newer versions ## Angular, Svelte, and Pieces I know just how tasking it can be to learn a new framework, but [Pieces](https://pieces.app/) can help.

postmark, multilingual, email, tutorial
In today's global landscape, connecting with customers in their preferred language is crucial. Whether through emails, messaging apps, or websites, communicating in a customer's native language builds stronger relationships and boosts transaction success. This is particularly true for transactional or notification emails, where crucial information can be easily missed if not presented in the recipient's language. In this post, we’ll dive into our journey of implementing multilingual transactional emails for spotsmap.com, exploring how our approach has evolved over time. Each method has its merits depending on your specific needs. Note: While we use Node.js for the examples, the concepts can be applied across various programming languages. ## The Challenge [Spotsmap.com](https://spotsmap.com) required a localized booking confirmation email that included details like sport types, dates, costs, and course information. The HTML template alone was over 500 lines of code. ## First Approach: Language-Specific Templates Initially, we created separate templates for each supported language. Our code included a configuration object to select the appropriate template based on the user's language. Here’s a simplified example of how it looked: ``` html <h2>Arrival date:</h2> <p>{{ArrivalDate}}</p> ``` And the code: ``` javascript // config.js export default { services: { email: { postmark: { apiKey: process.env.POSTMARK_API_KEY, templates: { bookingConfirmation: { 'en': 123456, 'de': 123457, 'es': 123458 } } } } } } // services/postmark.js export const sendMail = ({ from, to, template, locale, params }) => { const request = client.sendEmailWithTemplate({ From: from, To: to, MessageStream: 'outbound', TemplateId: postmarkConfig.templates[template][locale], TemplateModel: params || {}, }); request .then(result => { console.log(`Email sent to ${to}`); }) .catch(err => { console.log(`Email was not sent, with error code ${err.statusCode}, ${err.message}`); }); } ``` While straightforward, this approach became cumbersome as we had to replicate changes across multiple templates. When we added a feature to book multiple courses in a single order, updating each language-specific template became a headache. **Second Approach: Conditional Templates** We then moved to a single template with conditionals to handle multiple languages: ``` html <h2> {{#en}}Arrival date:{{/en}} {{#de}}Ankunftsdatum:{{/de}} {{#es}}Fecha de llegada:{{/es}} </h2> <p>{{ArrivalDate}}</p> ``` And the updated code: ``` javascript // config.js export default { services: { email: { postmark: { apiKey: process.env.POSTMARK_API_KEY, templates: { bookingConfirmation: 123456 } } } } } // services/postmark.js export const sendMail = ({ from, to, template, locale, params }) => { const request = client.sendEmailWithTemplate({ From: from, To: to, MessageStream: 'outbound', TemplateId: postmarkConfig.templates[template], TemplateModel: { ...params, [locale]: true }, }); request .then(result => { console.log(`Email sent to ${to}`); }) .catch(err => { console.log(`Email was not sent, with error code ${err.statusCode}, ${err.message}`); }); } ``` This solution worked well initially but soon became unwieldy as the number of languages and localized strings grew. For 40 languages, this method would lead to a bloated and unmanageable template. ## Third Approach: Code-Based Localization To streamline our process, we shifted localization strings from the template to our codebase, utilizing a standardized translation process similar to what we use for website UI localization. Our simplified template now looks like this: ``` html <h2>{{ArrivalDateTitle}}</h2> <p>{{ArrivalDate}}</p> ``` We created JSON files for localization strings, for example, `templates/en/bookingConfirmation.json` for English: ``` json { "ArrivalDateTitle": "Arrival date" } ``` And the updated `sendMail` function: ``` javascript // services/postmark.js export const sendMail = ({ from, to, template, locale, params }) => { const strings = require(`../templates/${locale}/${template}.json`); const request = client.sendEmailWithTemplate({ From: from, To: to, MessageStream: 'outbound', TemplateId: postmarkConfig.templates[template], TemplateModel: { ...params, ...strings }, }); request .then(result => { console.log(`Email sent to ${to}`); }) .catch(err => { console.log(`Email was not sent, with error code ${err.statusCode}, ${err.message}`); }); } ``` To automate the translation process using Gitloc, we created a `gitloc.yaml` file: ```yaml config: defaultLocale: en locales: - en - de - es directories: - templates ``` This approach allowed us to efficiently manage translations by simply updating the `gitloc.yaml` file and pushing changes to our remote repository. Gitloc handled the rest, ensuring we could support numerous languages without compromising our codebase’s maintainability. For more details, check out: - [Postmark Documentation](https://postmarkapp.com/developer) - [Gitloc Documentation](https://docs.gitloc.org/) We hope these insights help you streamline your multilingual email process!

Joining a new company can be challenging. You may feel like everyone is watching you and has high expectations. This can be stressful, especially at the beginning. Here is a simple pull request (PR) you can make during your first couple of weeks as a new joiner. In the software industry, you will often be introduced to an existing codebase and need to run it on your local setup. This process can be straightforward, like running `make start` or `npm start`, etc. If it runs smoothly, that's great. But if it doesn't, you'll likely need to dig deep to get it to work. This may involve installing some dependencies, such as Redis, among others. This is where you will shine. Take note of every step and action you take to make it work. Finally, refine those steps and update the repository's README file (_or create a new one if it doesn't exist_). Then, make a PR with that change. This not only helps others who join after you but also breaks the ice for you.

![usecase_content](https://cdn-images-1.medium.com/proxy/1*zqfBK-ivKOyE5TLv4mHkkA.png) # Building Highly Available and Scalable Web Applications with AWS Elastic Load Balancer Modern web applications demand high availability, scalability, and responsiveness to handle fluctuating traffic patterns and ensure a seamless user experience. AWS Elastic Load Balancer (ELB) is a fully managed service that plays a pivotal role in achieving these objectives. This blog post delves into the intricacies of ELB, explores various use cases, and examines alternative solutions offered by other cloud providers. ### Understanding Elastic Load Balancing Load balancing, in essence, is the art of efficiently distributing incoming network traffic across multiple servers. This distribution prevents any single server from becoming a bottleneck and ensures that your application remains responsive even during traffic surges. ELB accomplishes this by acting as a single point of contact for clients, receiving requests, and then routing them to healthy backend instances. ### Types of Elastic Load Balancers AWS provides three primary types of ELBs, each tailored for specific use cases: 1. **Application Load Balancer (ALB):** Operates at the application layer (Layer 7) of the OSI model, allowing routing decisions based on content such as HTTP headers, cookies, and path-based routing. This makes ALBs ideal for modern web applications built on microservices architecture or those requiring advanced routing capabilities. 2. **Network Load Balancer (NLB):** Operates at the transport layer (Layer 4), handling millions of requests per second with ultra-low latency. NLBs are well-suited for applications demanding extreme performance, such as gaming servers, streaming services, and high-frequency trading platforms. 3. **Classic Load Balancer (CLB):** Now considered legacy, CLBs provide basic load balancing across EC2 instances. While still functional, they lack the advanced features and performance optimization offered by ALBs and NLBs. ### Use Cases for ELB Let's explore several compelling use cases that showcase the power and versatility of Elastic Load Balancing: #### 1. High Availability for Web Servers **Challenge:** Ensuring uninterrupted website availability even if a web server experiences downtime. **Solution:** Deploy multiple EC2 instances running your web application behind an ELB. The ELB will continuously monitor the health of these instances. If one becomes unhealthy, ELB automatically reroutes traffic to the remaining healthy instances, providing fault tolerance and preventing service disruptions. #### 2. Scaling to Handle Peak Loads **Challenge:** Accommodating unpredictable spikes in traffic, such as during product launches or flash sales, without compromising performance. **Solution:** Implement ELB with Auto Scaling. When traffic surges, Auto Scaling automatically launches additional EC2 instances, and ELB seamlessly integrates them into the load-balanced pool. Conversely, during periods of low traffic, Auto Scaling removes instances to optimize costs. #### 3. Blue/Green Deployments and Canary Releases **Challenge:** Seamlessly deploying new application versions with minimal downtime and risk. **Solution:** Utilize ELB to facilitate blue/green deployments by routing traffic to a "blue" environment (existing version) while deploying and testing updates on a "green" environment. Once validated, switch all traffic to the "green" environment. This ensures a smooth transition and allows for quick rollback if issues arise. For canary releases, ELB can route a small percentage of traffic to a new version for testing and monitoring before a full rollout. #### 4. Content-Based Routing for Microservices **Challenge:** Routing traffic to specific microservices based on request characteristics like URL paths or headers. **Solution:** Leverage ALB's path-based routing feature to direct requests to different target groups representing individual microservices. This allows for efficient decoupling of functionalities and simplifies application architecture. For instance, requests to `/api/users` can be routed to the user management microservice, while requests to `/api/products` go to the product catalog microservice. #### 5. SSL Termination and Security Enhancement **Challenge:** Offloading SSL/TLS encryption/decryption to a dedicated service for improved performance and easier certificate management. **Solution:** Configure ELB to terminate SSL connections. This means that ELB handles the encryption and decryption of traffic between the client and the load balancer, forwarding decrypted requests to the backend instances. This not only reduces the processing load on your web servers but also centralizes certificate management, enhancing security. ### Alternatives to ELB While ELB excels within the AWS ecosystem, other cloud providers offer comparable load balancing services: - **Google Cloud Platform Load Balancing:** Offers a comprehensive suite of load balancers, including global HTTP(S) load balancers for distributing traffic across regions and internal load balancers for internal microservices communication. - **Azure Load Balancer:** Provides various load balancing solutions, such as Azure Application Gateway for Layer 7 routing and Azure Load Balancer for Layer 4 traffic distribution. Each platform boasts unique features and integrations within its respective ecosystem, so the optimal choice depends on specific project requirements. ### Conclusion AWS Elastic Load Balancer is an indispensable tool for architecting resilient, scalable, and secure web applications. By distributing incoming traffic, ensuring high availability, and simplifying deployments, ELB empowers developers to focus on building feature-rich applications without compromising on performance or reliability. --- ### Advanced Use Case: Building a Globally Distributed, Fault-Tolerant Application **Scenario:** Imagine building a real-time video streaming platform with a global user base. The platform requires low latency, high availability across multiple regions, and the ability to scale dynamically based on user demand. **Solution:** We can leverage multiple AWS services, including ELB, to architect this system: 1. **Global Traffic Management with Route 53:** Use Route 53, AWS's DNS service, to route traffic to the closest geographic region based on the user's location. This reduces latency and improves the user experience. 2. **Multi-Region Deployment:** Deploy identical copies of the application infrastructure (including EC2 instances, databases, and caching layers) in multiple AWS regions to ensure high availability even in the event of a regional outage. 3. **Network Load Balancing:** Utilize NLBs in each region to distribute incoming traffic across multiple Availability Zones within that region. This provides an additional layer of redundancy and fault tolerance. 4. **Application Load Balancing:** Employ ALBs to route traffic to specific microservices responsible for video encoding, streaming, user management, etc. This enables efficient scaling and management of individual components. 5. **Auto Scaling and Dynamic Scaling:** Configure Auto Scaling to dynamically adjust the number of EC2 instances based on real-time traffic patterns. Integrate with CloudWatch metrics to define scaling thresholds and ensure optimal resource utilization. 6. **Content Delivery Network (CloudFront):** Utilize CloudFront, AWS's CDN, to cache static content (images, videos, etc.) closer to users, further reducing latency and improving streaming performance. By combining ELB with these additional AWS services, we can build a robust, scalable, and globally distributed video streaming platform capable of delivering an exceptional user experience even under demanding conditions.

You will learn, - How to get the schema from the backend? - How to use a code generation tool with Typescript? - How to make a GraphQL API request? - How to handle expired JWT token? Lets dive in! ## Tools we will be using: **urql** This is the GraphQL client we will be using to make the API request possible. There are other alternatives like `houdini` and `apollo-client` but after struggling with them I found urql package to be much better. {% embed https://formidable.com/open-source/urql/docs/basics/svelte/?source=post_page-----bf3a32eee5bb-------------------------------- %} **urql/exchange-auth** This package or an addon acts like the request interceptor which will help us in renewing the expired token. {% embed https://formidable.com/open-source/urql/docs/api/auth-exchange/?source=post_page-----bf3a32eee5bb-------------------------------- %} **graphql-codegen/cli & graphql-codegen/client-preset** This is used for codegen for a typescript project. {% embed https://formidable.com/open-source/urql/docs/basics/typescript-integration/?source=post_page-----bf3a32eee5bb-------------------------------- %} Additionally, we will be using: - **Tailwindcss** — For CSS styling. - **jwt-decode** — To extract information stored in the JWT token. ## Files and Folder structure ``` src - lib - components - graphql - models - services - utils - index.ts - routes - login - stores app.css app.d.ts app.html codegen.ts vite.config.ts tailwind.config.js ``` ## Create a Svelte project with Typescript. Choose options below after running the command: - A Skeleton project - Yes, using TypeScript syntax - Add Prettier for code formatting ```bash npm create svelte@latest your_app_name ``` ## Installing dependencies ```json { "name": "svelte-app", "version": "0.0.1", "private": true, "scripts": { "dev": "vite dev", "build": "vite build", "preview": "vite preview", "codegen": "graphql-codegen", "check": "svelte-kit sync && svelte-check --tsconfig ./tsconfig.json", "check:watch": "svelte-kit sync && svelte-check --tsconfig ./tsconfig.json --watch", "lint": "prettier --plugin-search-dir . --check . && eslint .", "format": "prettier --plugin-search-dir . --write ." }, "devDependencies": { "@graphql-codegen/cli": "^5.0.0", "@graphql-codegen/client-preset": "^4.1.0", "@sveltejs/adapter-auto": "^2.1.1", "@sveltejs/kit": "^1.27.6", "@typescript-eslint/eslint-plugin": "^6.12.0", "@typescript-eslint/parser": "^6.12.0", "autoprefixer": "^10.4.16", "eslint": "^8.54.0", "eslint-config-prettier": "^9.0.0", "eslint-plugin-svelte": "^2.35.1", "graphql": "^16.8.1", "postcss": "^8.4.31", "prettier": "^3.1.0", "prettier-plugin-svelte": "^3.1.2", "svelte": "^4.2.7", "svelte-check": "^3.6.2", "tailwindcss": "^3.3.5", "tslib": "^2.6.2", "typescript": "^5.3.3", "vite": "^5.0.2" }, "type": "module", "dependencies": { "@urql/exchange-auth": "^2.1.6", "@urql/svelte": "^4.0.4", "jwt-decode": "^4.0.0", "svelte-use-form": "^2.10.0" } } ``` ## Configuring code generation (for Typescript) Create a _codegen.ts_ file in the root of the project and add the following content. Replace base url on the `schema` property below. Depending on the env introspection can be enabled or disabled in the backend. By default introspection should be enabled. ```typescript // codegen.ts import { CodegenConfig } from '@graphql-codegen/cli'; const config: CodegenConfig = { schema: 'http://localhost:8000/graphql', documents: ['src/**/*.svelte', 'src/**/*.ts'], ignoreNoDocuments: true, generates: { './src/lib/graphql/': { // Folder to store downloaded GrapqhQL Schema. preset: 'client', plugins: [], }, }, }; export default config; ``` ## Configuring Tailwindcss Create _tailwind.config.js_ in the root of your project and add the following content. ```javascript // tailwind.config.js /** @type {import('tailwindcss').Config} */ export default { content: ['./src/**/*.{html,js,svelte,ts}'], theme: {}, plugins: [] }; ``` Now import tailwindcss in the _**src/app.css**_ file. ```css * src/app.css */ @tailwind base; @tailwind components; @tailwind utilities; ``` ## Configuring Storage for Auth Tokens Create _local-storage.service.ts_ to store the auth tokens. > We are using try-catch block to prevent errors when Svelte tries to access localStorage in the server. As localStorage is only available in the browser. ```typescript // src/lib/services/local-storage.service.ts export const accessTokenKey = "access_token"; export const refreshTokenKey = "refresh_token"; export function saveAuthTokens(accessToken: string, refreshToken: string) { localStorage.setItem(accessTokenKey, accessToken); localStorage.setItem(refreshTokenKey, refreshToken); } export function getAccessToken(): string | null { try { return localStorage.getItem(accessTokenKey); } catch { return null; } } export function getRefreshToken(): string | null { try { return localStorage.getItem(refreshTokenKey); } catch { return null; } } export function saveNewAccessToken(newToken: string) { localStorage.setItem(accessTokenKey, newToken); } export function clearAuthTokens(): void { localStorage.clear() } ``` ## Dowloading our API schema from the backend Recheck _package.json_ file above if you encounter any issues here. ```bash yarn codegen ``` ## Adding our GraphQL endpoints Get the Auth Queries defined in the backend. ```typescript // src/lib/graphql/queries/auth.ts import { gql } from "@urql/svelte" import type { AuthMutationsRenewTokenArgs, AuthQueriesLoginArgs, LoginSuccess, LogoutSuccess, RenewTokenSuccess } from "../graphql" export const LOGIN_QUERY = gql<{ auth: { login: LoginSuccess } }, AuthQueriesLoginArgs>` query Login($input: LoginInput!) { auth { login(input: $input) { ... on LoginSuccess { __typename accessToken refreshToken } } } } ` export const RENEW_TOKEN_MUTATION = gql<{ auth: { renewToken: RenewTokenSuccess } }, AuthMutationsRenewTokenArgs>` mutation RenewAccessToken($input: RenewTokenInput!) { auth { renewToken(input: $input) { ... on RenewTokenSuccess { __typename newAccessToken } } } } ` export const LOGOUT_MUTATION = gql<{ auth: { logout: LogoutSuccess } }, { accessToken: string }>` mutation Logout($accessToken: String!) { auth { logout(accessToken: $accessToken) { ... on LogoutSuccess { __typename success } } } } ` ``` ## Configuring Urql client Update _vite.config.ts_ as shown below. ```javascript // vite.config.ts import { sveltekit } from '@sveltejs/kit/vite' import { defineConfig } from 'vite' export default defineConfig({ plugins: [sveltekit()], optimizeDeps: { exclude: ['@urql/svelte'], } }); ``` Now add the _**base.service.ts**_ file to configure the Urql client. This is also where we will renew the access-token when required. ```typescript import { goto } from "$app/navigation"; import { jwtDecode } from "jwt-decode"; import { dev } from "$app/environment"; import { Client, cacheExchange, fetchExchange } from "@urql/svelte"; import { authExchange, type AuthUtilities } from "@urql/exchange-auth"; import { RENEW_TOKEN_MUTATION } from "$lib/graphql/queries/auth"; import { clearAuthTokens, getAccessToken, getRefreshToken, saveNewAccessToken } from "./local-storage.service"; const auth = authExchange(async (utilities: AuthUtilities) => { let token = getAccessToken(); let refreshToken = getRefreshToken(); return { addAuthToOperation(operation) { return token ? utilities.appendHeaders(operation, { Authorization: `Bearer ${token}`, }) : operation; }, didAuthError(error) { // Check for "Forbidden" error response, caused when access token has expired. return error.response?.status === 403; }, willAuthError() { // Sync tokens on every operation token = getAccessToken(); refreshToken = getRefreshToken(); if (token) { // If JWT has expired then run the refreshAuth func. const { exp } = jwtDecode(token); if (Date.now() >= exp! * 1000) return true; } return false; }, async refreshAuth() { // Clear the token for refresh token API to be called without any issues. // addAuthToOperation will fail if token is not set to null. token = null; if (refreshToken) { try { const result = await utilities.mutate(RENEW_TOKEN_MUTATION, { input: { refreshToken }, }); if (result.error) { clearAuthTokens(); goto("/login"); } else if (result.data?.auth.renewToken.newAccessToken) { const renewedToken = result.data.auth.renewToken.newAccessToken; token = renewedToken; saveNewAccessToken(renewedToken); } } catch (e) { console.log("Refresh Token Error", e); } } }, }; }); const gqlClient = new Client({ requestPolicy: "network-only", exchanges: [cacheExchange, auth, fetchExchange], url: dev ? "http://localhost:8000/graphql" : "<your_production_url>", }); export default gqlClient; ``` Now initialize the gqlClient we created above in our app. ```svelte <!-- src/routes/+page.svelte --> <script lang="ts"> import { onMount } from 'svelte'; import { goto } from '$app/navigation'; import { setContextClient } from '@urql/svelte'; import gqlClient from '../lib/services/base.service'; import { getAccessToken } from '$lib/services/local-storage.service'; onMount(() => { const accessToken = getAccessToken(); const visitingRoute = location.pathname; if (!accessToken) return goto(`/login`); if (visitingRoute === '/') return goto(`/dashboard`); }); setContextClient(gqlClient); </script> <p>loading...</p> ``` ## Create the auth service file ```typescript // src/lib/services/auth.service.ts import gqlClient from "./base.service"; import type { LoginSuccess } from "$lib/graphql/graphql"; import { LOGIN_QUERY, LOGOUT_MUTATION } from "$lib/graphql/queries/auth"; const login = async (identifier: string, password: string): Promise<LoginSuccess | undefined> => { const result = await gqlClient.query(LOGIN_QUERY, { input: { identifier, password } }).toPromise(); if (result.error) throw result.error; return result.data!.auth.login; } const logout = async (accessToken: string) => { const result = await gqlClient.mutation(LOGOUT_MUTATION, { accessToken }).toPromise(); if (result.error) throw result.error; return result.data; } const authService = { login, logout, } export default authService; ``` ## Creating our login page ```svelte <!-- src/routes/login/+layout.svelte --> <div class="flex flex-col flex-1 bg-white justify-center"> <div class="m-10 flex flex-grow flex-col rounded-2xl items-center p-5"> <slot /> </div> </div> ``` ```svelte <!-- src/routes/login/+page.svelte --> <script lang="ts"> import { goto } from '$app/navigation'; import { useForm, Hint, validators, email, required, HintGroup } from 'svelte-use-form'; import authService from '$lib/services/auth.service'; import { notifierStore } from '../../stores/notifier.store'; import { saveAuthTokens } from '$lib/services/local-storage.service'; import LoadingButtonXL from '$lib/components/shared/loading-button-xl.svelte'; const form = useForm(); let password: string; let userEmail: string; let isLoading = false; async function onLogin() { if (isLoading) return; try { isLoading = true; const data = await authService.login(userEmail, password); saveAuthTokens(data!.accessToken, data!.refreshToken); goto('/dashboard'); } catch (e) { handleError(e); } finally { isLoading = false; } } function onForgotPassword() {} function handleError(error: any) { if (typeof error === 'string') { console.log(error); } else if (error instanceof Error) { console.log(error.message); } } </script> <div class="lg:w-9/12 w-full flex flex-col lg:mt-52 text-gray-500"> <h1 class="text-4xl text-black mb-10 text-center">Login to Continue</h1> <form use:form class="w-full flex flex-col" on:submit|preventDefault={$form.valid ? onLogin : null} > <input type="email" name="email" placeholder="Email" bind:value={userEmail} use:validators={[required, email]} class="border border-gray-200 rounded-2xl py-5 px-6 text-xl tracking-wide text-gray-600" /> <HintGroup for="email"> <Hint class="text-red-800 m-2" on="required">This is a mandatory field.</Hint> <Hint class="text-red-800 m-2" on="email" hideWhenRequired>Email is not valid.</Hint> </HintGroup> <input type="password" name="password" bind:value={password} placeholder="Password" use:validators={[required]} class="border border-gray-200 rounded-2xl py-5 px-6 mt-4 text-xl tracking-wide text-gray-600" /> <HintGroup for="password"> <Hint class="text-red-800 m-2" on="required">This is a mandatory field.</Hint> </HintGroup> <button class="text-MD mt-2 self-end" on:click={onForgotPassword}>Forgot Password?</button> <button type="submit" class="bg-app-primary flex flex-row items-center justify-center text-white my-5 rounded-2xl p-4" > {#if isLoading} your_loading_spinner {/if} <span class="ml-2">LOGIN</span> </button> </form> </div> ``` That should be it!

Components in React serve as the fundamental building blocks of an application. Essentially, a React component returns a JSX element that is rendered in the user interface. Additionally, a component can encompass other features such as state management, properties (props), and lifecycle methods. React categorizes components into two main types: - Functional components: These are JavaScript functions that return JSX elements. Initially, they were stateless components, lacking support for managing state. However, with the introduction of React hooks in version 16.8, functional components gained the ability to declare and manage state, transforming them into stateful components. ![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/o1i6ewlv7wom6kuxcrpd.png) In the above code, SayHello is a functional component and it is returning a JSX element. In the end, the SayHello function is being exported. Basically, SayHello is nothing but a plain JavaScript function. - Class components: These are JavaScript classes extended to React.Component. They require a mandatory render() method that returns a JSX element. Historically, React heavily relied on class components because only they supported local state management ("state"). ![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/hbghkyi0884otgoq4ds0.png) The above class component is the equivalent of the earlier functional component. It is easily observable that the functional component is more easily readable than the class component. Moreover, it is easier to work with functional components because writing class components is more complex and complicated. #Class Component These are mounting, updating, and unmounting. The lifecycle methods are very useful because sometimes, we may want to execute a piece of code at a specific time. For example, suppose we want to call an API just after the component is mounted. In such a case, we can use the componentDidMount lifecycle method. ## Mounting phase with componentDidMount This is the first stage of a React component’s lifecycle where the component is created and inserted into the DOM.The componentDidMount lifecycle method executes once after initial rendering. If an empty dependency array is provided as the second argument, the callback function executes only after initial rendering. ![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/1ww6h9f0y8onlmwr119u.png) ## Analyze variables before loading using the constructor. ![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/gvcg1cx8cz3nzb9dypgj.png) 1.Constructor (constructor()):The `constructor()` method is a special method for initializing state (this.state) and binding event handler methods. In this code, super() is called to invoke the constructor of the parent Component class (from which App extends). Then, this.state is initialized with an object containing count: 0. 2.Component Did Mount (componentDidMount()):`componentDidMount()` is a lifecycle method that is called immediately after a component is mounted (i.e., inserted into the DOM tree). In this code, it logs a message to the console indicating that the component has rendered for the first time. This is useful for performing actions that require DOM nodes or initial state setup. 3.Increment Method (increment()):`increment()` is a custom method defined within the App class. When called, it updates the component's state using `this.setState()`. In React, `setState()` is used to update state values asynchronously. Here, it increments the count state by 1 each time the button is clicked. 4.Component Will Unmount (componentWillUnmount()):This lifecycle method is called just before the component is removed from the DOM. It's useful for cleanup activities such as cancelling network requests, removing event listeners, or cleaning up subscriptions. Here, it logs a message indicating that the component is being removed. 5.Render Method (render()):The `render()` method is a required method in every React component class. It returns JSX (JavaScript XML) that defines the UI of the component. In this code, it renders a `<div>` containing an `<h1>` element displaying the current value of `this.state.count` and a `<button>` element that calls `this.increment()` when clicked. Binding Methods: •Method 1:Arrow Function in Render Method `(onClick={() => { this.increment() }})`:This approach creates a new function instance every time the component renders. While straightforward, this can lead to performance implications, especially in larger applications. •Method 2:Binding in Constructor `(onClick={this.increment.bind(this)})`: This approach binds this.increment() to the current instance of App in the constructor. It ensures that this refers to the component instance when increment() is called, avoiding the need for creating new function instances on each render. Lifecycle Summary: •Mounting Phase:During the mounting phase, React calls the constructor() first, initializing state. Then, render() is called, returning JSX to render the component's UI. Finally, componentDidMount() is invoked after the component is rendered for the first time, where initialization tasks, API calls, or subscriptions can be performed. •State Management:this.state allows components to manage their own state. Updates to state using this.setState() trigger re-rendering of the component, ensuring UI remains synchronized with data changes. ## Updating phase with componentDidUpdate This updating stage occurs after the component has mounted and rendered into the DOM. A React component updates when there is a change in its props or state. The componentDidUpdate lifecycle method is invoked after the component updates. This method can be used to compare if a specific prop or state has changed. ![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/mye0j41wkmvljhuz28iw.png) ![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/64tn70jg6kc8e8pw53ce.png) - Component Did Update `(componentDidUpdate(prevProps, prevState))`: componentDidUpdate() is a lifecycle method invoked immediately after a component updates and after render() is called. It receives two arguments: o prevProps: Represents the previous props before the update. o prevState: Represents the previous state before the update. - `if (prevProps.number !== this.props.number) { console.log("Component Updated"); }`: Compares the current number prop `(this.props.number)` with its previous value `(prevProps.number)`. If they differ, it logs "Component Updated" to indicate that the component has been updated due to a change in props. Updating Phase: • During the updating phase, React compares the previous props and state with the current props and state to determine if the component needs to re-render. componentDidUpdate() is called after this comparison and rendering process. • It is typically used for operations that need to be performed after a component updates, such as fetching new data based on props changes or interacting with the DOM. ## Now, let's see how this can be achieved in a functional component. The useEffect hook is used to perform side effects in functional components. It takes two arguments: a callback function and a dependency array. The callback function executes based on the presence and values in the dependency array. This is how lifecycle method-like functionality is achieved in functional components. ![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/sxtdc9av2dwviza248qp.png) • Cleanup Function: The function returned from the useEffect hook is the cleanup function. It runs when the component is unmounted or before the effect is re-executed due to dependency changes. Here, it logs "Functional Component: Removed" to the console. • Dependency Array: The second argument to useEffect is the dependency array. This array specifies the dependencies that the effect depends on. If any value in this array changes, the effect will re-run. In this case, [number] indicates that the effect should re-run whenever the number prop changes. ## Lifecycle Summary in the Context of useEffect: • Mounting Phase: When the Counter1 component is first rendered, useEffect runs and logs "Functional Component: Updating..." to the console. • Updating Phase: Whenever the number prop changes, useEffect runs again. Before running the effect function, React calls the cleanup function from the previous effect, logging "Functional Component: Removed" and then logs "Functional Component: Updating..." again. • Unmounting Phase: When the Counter1 component is removed from the DOM, the cleanup function from the last effect run is called, logging "Functional Component: Removed" to the console. ## State in functional components Initially, it was not possible to use state in functional components because the setState() method was only supported in class components. However, with the introduction of React hooks, it is now possible to use state in functional components. The state of a component in React is a plain JavaScript object that controls the behavior of the component. A change in state triggers a re-render of the component. There are two main React hooks used to declare and manipulate the state in a functional component: - useState - useReducer ![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/0ck5laj41vs39kp0amlm.png) The Counter functional component in React uses the useState hook to manage a count state variable. The useState(0) hook initializes count to 0 and provides a setCounter function to update it. The component returns a fragment containing two buttons and an `<h2>` element. The first button increments the count by 1, and the second button decrements the count by 1, both using the setCounter function. The current count value is displayed inside the `<h2>` element. This demonstrates how to handle state and update it in response to user actions using the useState hook in a functional component. The useReducer hook is used for complex state management. When the state is interdependent, the useReducer hook is preferred over the useState hook. To understand useReducer, one should know what a reducer is and how to use it. A reducer is essentially a pure function that takes the current state and an action as arguments and returns a new state. It is very similar to the useState hook but instead of creating a function to update the state, the useReducer hook creates a function for dispatching actions. The useReducer hook has two arguments - reducer and an initialState. There is a third optional argument for initializing the state lazily. Following is the syntax of the useReducer hook. ![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/5n9g2w3d8usihx6dbti9.png)

One crucial aspect of React development is managing environment variables, which can be effectively handled using the `.env` file. In this guide, we will delve deep into the usage of the `.env` file in React, covering its purpose, best practices, and real-world applications. ## What is an .env File? The `.env` file is a simple text file used to store environment variables, which are key-value pairs that configure the environment in which your application runs. Environment variables are used to separate configuration settings from your code, making your application more secure and easier to manage. ### Why Use an .env File? 1. **Security**: Sensitive information such as API keys, database credentials, and secret tokens can be stored in the `.env` file, keeping them out of your source code. 2. **Configurability**: Environment variables allow you to change the behavior of your application without modifying the codebase. 3. **Portability**: By using environment variables, you can easily switch between different environments (development, testing, production) with minimal configuration changes. ## Setting Up an .env File in a React Project To use environment variables in a React project, you need to follow these steps: ### Step 1: Create the .env File In the root directory of your React project, create a file named `.env`. This file will contain all your environment variables. For example: ```plaintext REACT_APP_API_URL=https://api.example.com REACT_APP_API_KEY=your_api_key_here ``` ### Step 2: Prefix Your Variables React requires all environment variables to be prefixed with `REACT_APP_`. This prefix ensures that only the variables meant for React applications are included in the build. ### Step 3: Accessing Environment Variables To access the environment variables in your React application, use `process.env.REACT_APP_VARIABLE_NAME`. Here’s an example: ```javascript const apiUrl = process.env.REACT_APP_API_URL; const apiKey = process.env.REACT_APP_API_KEY; console.log("API URL:", apiUrl); console.log("API Key:", apiKey); ``` ### Step 4: Using .env Variables in Your React App You can use environment variables to configure various parts of your React application. For instance, you might use them to set the API endpoint URL or to enable/disable features based on the environment. ### Step 5: Add .env to .gitignore To ensure that your `.env` file is not committed to version control (e.g., GitHub), add it to your `.gitignore` file: ```plaintext .env ``` This prevents sensitive information from being exposed in your repository. ## Best Practices for Using .env Files 1. **Limit Scope**: Only include necessary variables in your `.env` file. Avoid storing large amounts of data or sensitive information that doesn’t need to be accessed by your application. 2. **Use Different Files for Different Environments**: Create separate `.env` files for different environments, such as `.env.development`, `.env.production`, and `.env.test`. This approach ensures that environment-specific configurations are isolated. 3. **Validate Variables**: Validate the presence and correctness of your environment variables during the application startup to avoid runtime errors. 4. **Document Variables**: Keep a sample `.env` file (`.env.example`) with placeholder values to document the necessary environment variables for your project. ## Real-World Applications of .env Files in React ### Configuring API Endpoints One common use case for environment variables is configuring API endpoints. Depending on the environment, your application might need to interact with different APIs. Here’s how you can achieve this using `.env` files: ```plaintext // .env.development REACT_APP_API_URL=https://dev-api.example.com // .env.production REACT_APP_API_URL=https://api.example.com ``` In your React code, you can access the API URL like this: ```javascript const apiUrl = process.env.REACT_APP_API_URL; fetch(`${apiUrl}/data`) .then(response => response.json()) .then(data => console.log(data)) .catch(error => console.error('Error:', error)); ``` ### Enabling/Disabling Features You can use environment variables to enable or disable features based on the environment. For example, you might want to enable debugging tools only in the development environment: ```plaintext // .env.development REACT_APP_ENABLE_DEBUG=true // .env.production REACT_APP_ENABLE_DEBUG=false ``` In your React code, you can conditionally enable features based on the environment variable: ```javascript if (process.env.REACT_APP_ENABLE_DEBUG === 'true') { console.log('Debugging is enabled'); } ``` ### Configuring Third-Party Services Many applications rely on third-party services like Google Analytics, Firebase, or Stripe. You can configure these services using environment variables to keep your credentials secure: ```plaintext REACT_APP_GOOGLE_ANALYTICS_ID=your_google_analytics_id REACT_APP_FIREBASE_API_KEY=your_firebase_api_key REACT_APP_STRIPE_PUBLIC_KEY=your_stripe_public_key ``` In your React code, you can initialize these services using the environment variables: ```javascript const analyticsId = process.env.REACT_APP_GOOGLE_ANALYTICS_ID; const firebaseApiKey = process.env.REACT_APP_FIREBASE_API_KEY; const stripePublicKey = process.env.REACT_APP_STRIPE_PUBLIC_KEY; // Initialize Google Analytics ReactGA.initialize(analyticsId); // Initialize Firebase firebase.initializeApp({ apiKey: firebaseApiKey, // Other Firebase config }); // Initialize Stripe const stripe = Stripe(stripePublicKey); ``` ## Advanced Usage of .env Files in React ### Custom Environment Variables While React enforces the `REACT_APP_` prefix for environment variables, you might encounter scenarios where you need to use custom environment variables. This can be achieved by using tools like `dotenv` and `cross-env`. #### Using dotenv `dotenv` is a popular library for loading environment variables from a `.env` file into `process.env`. To use `dotenv` with React, you need to install it and create a custom script to configure the environment variables: ```bash npm install dotenv ``` Create a `config.js` file to load the environment variables: ```javascript require('dotenv').config(); const webpack = require('webpack'); module.exports = function override(config) { config.plugins = (config.plugins || []).concat([ new webpack.DefinePlugin({ 'process.env': JSON.stringify(process.env), }), ]); return config; }; ``` In your `package.json`, add a custom script to run the configuration: ```json "scripts": { "start": "node config.js && react-scripts start", "build": "node config.js && react-scripts build", "test": "node config.js && react-scripts test" } ``` #### Using cross-env `cross-env` is another tool that allows you to set environment variables across different platforms. It ensures that environment variables are set correctly regardless of the operating system. To use `cross-env`, install it as a development dependency: ```bash npm install cross-env --save-dev ``` Modify your `package.json` scripts to use `cross-env`: ```json "scripts": { "start": "cross-env REACT_APP_API_URL=https://api.example.com react-scripts start", "build": "cross-env REACT_APP_API_URL=https://api.example.com react-scripts build", "test": "cross-env REACT_APP_API_URL=https://api.example.com react-scripts test" } ``` ### Dynamic Environment Variables In some cases, you might need to set environment variables dynamically at runtime. One approach is to use a server-side endpoint to fetch configuration settings. This method is particularly useful for sensitive information that should not be exposed in the client-side code. #### Server-Side Configuration 1. **Create a Server Endpoint**: Set up an endpoint on your server to provide configuration settings. 2. **Fetch Configuration**: In your React application, fetch the configuration settings from the server and store them in the application state or a context provider. 3. **Use Configuration**: Access the configuration settings throughout your application as needed. Here’s an example of fetching configuration settings from a server: ```javascript // server.js const express = require('express'); const app = express(); app.get('/config', (req, res) => { res.json({ apiUrl: process.env.API_URL, apiKey: process.env.API_KEY, }); }); app.listen(3001, () => { console.log('Server is running on port 3001'); }); ``` ```javascript // App.js import React, { useEffect, useState } from 'react'; function App() { const [config, setConfig] = useState({}); useEffect(() => { fetch('/config') .then(response => response.json()) .then(data => setConfig(data)) .catch(error => console.error('Error fetching config:', error)); }, []); return ( <div> <h1>React App with Dynamic Environment Variables</h1> <p>API URL: {config.apiUrl}</p> <p>API Key: {config.apiKey}</p> </div> ); } export default App; ``` ## Conclusion Using the `.env` file in a React application is a powerful way to manage environment variables, making your application more secure, configurable, and portable. By following the best practices and real-world examples outlined in this guide, you can effectively utilize environment variables to enhance your React development workflow. Here are some key takeaways: - **Security**: Keep sensitive information out of your source code by using environment variables. - **Configurability**: Easily change the behavior of your application without modifying the codebase by leveraging different `.env` files for different environments. - **Portability**: Seamlessly switch between development, testing, and production environments by using environment-specific configuration files. - **Best Practices**: Validate, document, and limit the scope of your environment variables to ensure a robust and maintainable application. - **Advanced Techniques**: Use tools like `dotenv` and `cross-env` for custom environment variable management and fetch dynamic configuration settings at runtime when necessary. By integrating these strategies into your React projects, you will be better equipped to handle various configuration challenges, resulting in more efficient and maintainable applications. ## Further Reading and Resources To further deepen your understanding and skills in managing environment variables in React, consider exploring the following resources: 1. **React Documentation**: The official React documentation provides comprehensive insights into various React features and best practices. - [React Environment Variables](https://create-react-app.dev/docs/adding-custom-environment-variables/) 2. **Dotenv Documentation**: Learn more about the `dotenv` package and how to use it for loading environment variables. - [Dotenv GitHub Repository](https://github.com/motdotla/dotenv) 3. **Cross-env Documentation**: Understand how `cross-env` helps in setting environment variables across different platforms. - [Cross-env GitHub Repository](https://github.com/kentcdodds/cross-env) 4. **Securing API Keys**: Explore strategies for securing API keys and other sensitive information in your frontend applications. - [Securing API Keys in Frontend Apps](https://www.netlify.com/blog/2021/01/13/securing-your-api-keys-in-a-front-end-app/) 5. **Web Security Best Practices**: Delve into web security best practices to protect your applications from potential vulnerabilities. - [OWASP Top Ten](https://owasp.org/www-project-top-ten/) By continuously learning and applying these best practices, you can enhance the security, flexibility, and maintainability of your React applications.

While everybody trying to tap on this little rodent animal, u might actually have a chance to get some real money with some real crypto exchange bot - Blum Blum combines the functionality of a centralized and decentralized exchange. That is, in one place you will be able to trade all cryptocurrencies that are traded on both centralized and decentralized ![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/zjro7rrflrm3424ubhbm.jpg) http://t.me/BlumCryptoBot/app?startapp=ref_ahCHBJGc0Q How Blum will allow you to earn — farm crypts inside the application, when listing coins, a convenient exchange and the opportunity to make a profit for the game. ## What is interesting about Blum Blum is in Beta testing. There has not been a public launch of the project yet, you can only log in using a referral link. Blum is not just a toy. They have a playful approach, but it's more than just a tap game. Blum is a serious product that has a serious goal and mission to engage people and simplify their entry into the world of cryptocurrency. The founders of Blum are former employees of the Binance exchange. ## How to play and earn points 1. The game. Every day, all players are given bonus tickets. 1 ticket allows you to play 1 time. One ticket is also given for each invited referral. In total, you can invite 10 referrals. ![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/nxu9r6kyj2ublqx2i84y.jpg) The game has the simplest possible mechanics. You need to stomp on the flowers, points are awarded for this. Avoid bombs (all points will burn out). Be sure to click on the crystals — time stops, so you will have time to get more flowers. In the future, it is planned to add a drop not only of flowers, but also of real coins of various cryptocurrencies. ![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/vdm4k7sk1ledhtgpn59r.jpg) 2. You need to come in once every 8 hours and collect the drop. A button on the main screen. Be sure to press the button 2 times: 1 time to assemble, 2 times to start the farm again. If you don't start the farm, it won't start. 3. Complete the tasks. They are periodically updated. This is a good opportunity to earn more points. Blum is not just another "tapalka", in the future it will be a real exchange where you can trade. Moreover, it will be as simple as possible for beginners. The goal of the project is to minimize the entry threshold to the crypto world for beginners. To join this game u should go to the link - the number of places are limited. Otherwise u have to wait in a waitlist. http://t.me/BlumCryptoBot/app?startapp=ref_ahCHBJGc0Q

## PROJECT OVERVIEW. This project utilize the following tools **Node JS**: [Node.js](https://nodejs.org/en/learn/getting-started/introduction-to-nodejs) is an open-source and cross-platform JavaScript runtime environment. It is a popular tool for almost any kind of project! Node.js runs the V8 JavaScript engine, the core of Google Chrome, outside of the browser. This allows Node.js to be very performant. A Node.js app runs in a single process, without creating a new thread for every request. Node.js provides a set of asynchronous I/O primitives in its standard library that prevent JavaScript code from blocking and generally, libraries in Node.js are written using non-blocking paradigms, making blocking behavior the exception rather than the norm. **React**: The client FrontEnd Framework **The sCrypt-CLI Tool**: [The sCrypt CLI tool](https://github.com/sCrypt-Inc/scrypt-cli) is used to easily create, compile and publish sCrypt projects. The CLI provides best practice project scaffolding including dependencies such as sCrypt, a test framework ([Mocha](https://mochajs.org/)), code auto-formatting ([Prettier](https://prettier.io/)), linting ([ES Lint](https://eslint.org/)), & more. **TypeScript**: We chose [TypeScript](https://www.typescriptlang.org/) as the host language because it provides an easy, familiar language (JavaScript), but with type safety, making it easy to get started writing safe smart contracts. There is no need to learn a new programming language or tools if you are already familiar with TypeScript/JavaScript. If you're new to TypeScript, check out this helpful introductory video. **Yours Wallet**: **Yours Wallet** formerly called **Panda Wallet** is an open-source digital wallet for BSV and [1Sat Ordinals](https://docs.1satordinals.com/) that enables access to decentralized applications developed on [Bitcoin SV](https://bitcoinsv.com/). This guide specifically looks into how to create a Full Stack **Hello World React dApp** and integrate it with a smart contract **Hello World** as an example. It goes further to describe how to wrap your dApp with Yours Wallet integration in case you want to create a dApp with live Wallet integration. It covers basic installations, setting up of development environment, writing smart contracts with sCrypt, integration with Yours wallet, building FrontEnd with React and TypeScript, integrating smart contract with the FrontEnd and testing the dApp. The project shows the basics of building a react dApp that integrates with contract writing with sCrypt on BSV blockchain. ##BASIC INSTALLATIONS. Install Node.js (require version >=16) and NPM on your machine by following the instructions over [here](https://nodejs.org/en/download). Install [Git](https://git-scm.com/book/en/v2/Getting-Started-Installing-Git). NOTE On Mac computers with Apple silicon like M1/M2, make sure [Rosetta](https://support.apple.com/en-us/102527) is installed. If not, it can be installed with the following command. softwareupdate --install-rosetta --agree-to-license 3. Install sCrypt-cli globally to your machine by running the code below: ``npm install -g scrypt-cli`` 4. You can start playing with react since Node JS has been installed. The npm has been installed together which is a package manager for react. To learn more about react installation, check [here](https://react.dev/learn/installation). 5. TypeScript comes preconfigured with Create React App, so you don't need to install it separately. In case you need to, TypeScript can be installed through three installation routes depending on how you intend to use it: an npm module, a NuGet package or a Visual Studio Extension. Since we are using Node.js, we will use npm version. If you are using MSBuild in your project, you want the NuGet package or Visual Studio extension. Run the code below: ``npm install -g typescript`` To learn more about typescript installation, check [here](https://www.typescriptlang.org/download). 6. Create your Yours Wallet formerly called Panda wallet. You can get its chrome extension [here](https://chromewebstore.google.com/detail/yours-wallet/mlbnicldlpdimbjdcncnklfempedeipj). **SETTING UP DEVELOPMENT ENVIRONMENT** 1. Make sure you have Node.js and npm installed on your system. You can run the code below to check: ``` node --version V20.11.0 npm --version 10.4.0 ``` You will get output similar to the above if your Node.js and npm has been installed. Note that you need Node.Js version 16 and above. Check the installation guide links in case your Node.js is not properly installed. ## CREATE YOUR BACKEND. It is a good practice to always create a backend for a dApp project. The proper build and deployment of a backend gives better functionalities and directions on what the features of the backend that the frontend can better interact with. It can also give a clue on how to design the frontend. 1. Create a new smart contract project “hello world” by running the following command in your visual studio code editor or on linux: --- ``npx scrypt-cli project helloworld``. This will create the smart contract project “hello world” in HELLOWORLD directory on the local machine. ``cd helloworld`` This allowed us to migrate into the project directory hello world where we have the smart contract file. ``npm install`` This command installs the necessary dependencies we need for the smart contract in the project directory. The resulting project will contain a sample smart contract ``src/contracts/helloworld.ts``, along with all the scaffolding. Let's modify it to the following code: ``` import { assert, ByteString, method, prop, sha256, Sha256, SmartContract, } from 'scrypt-ts' export class Helloworld extends SmartContract { @prop() hash: Sha256 constructor(hash: Sha256) { super(...arguments) this.hash = hash } @method() public unlock(message: ByteString) { assert(sha256(message) == this.hash, 'Hash does not match') } } ``` The Helloworld contract stores the `sha256 hash` of a message in the contract property hash. Only a message which hashes to the value set in this.hash will unlock the contract. A smart contract extends `SmartContract` base class, it has `@prop decorator` which marks the `helloworld` contract property and `@method decorator` which marks the contract’s method that can be [public](https://docs.scrypt.io/how-to-write-a-contract/#method-decorator) or [non-public](https://docs.scrypt.io/how-to-write-a-contract/#method-decorator). 2. Compile the smart contract by running the command below: --- `npx scrypt-cli compile` This command will generate a contract artifact file at artifacts\helloworld.json. In order to monitor for real time error detection you can run the following code: `npx scrypt-cli compile --watch` ``` 3:35:32 PM - Starting compilation in watch mode... 3:36:01 PM - Found 0 errors. Watching for file changes. ``` The message above is a similar message you will get in your terminal, meaning that auto compilation is working. 3. Deploy your contract: Before deploying your contract, you need to generate a Bitcoin key by running the command below: --- `npm run genprivkey` **then follow the [instructions](https://docs.scrypt.io/how-to-deploy-and-call-a-contract/faucet) to fund the key**. **Next, start deploying and calling the contract: 1. To [deploy a smart contract](https://docs.scrypt.io/how-to-deploy-and-call-a-contract/#contract-deployment), simply call its deploy method. 2. To [call a smart contract](https://docs.scrypt.io/how-to-deploy-and-call-a-contract/#contract-call), call one of its public method.** We need to overwrite “deploy.ts” in the root of the project with the following code to deploy and call the Helloworld contract as shown below: ``` import { Helloworld } from './src/contracts/helloworld' import { getDefaultSigner } from './tests/utils/txHelper' import { toByteString, sha256 } from 'scrypt-ts' ;(async () => { // set network env process.env.NETWORK = 'testnet' const message = toByteString('hello world', true) await Helloworld.loadArtifact() const instance = new Helloworld(sha256(message)) // connect to a signer await instance.connect(getDefaultSigner()) // deploy the contract and lock up 42 satoshis in it const deployTx = await instance.deploy(42) console.log('Helloworld contract deployed: ', deployTx.id) // contract call const { tx: callTx } = await instance.methods.unlock(message) console.log('Helloworld contract `unlock` called: ', callTx.id) })() ``` Run the following command to deploy the smart contract: `npx ts-node deploy.ts` You will see an output like this ![helloworld contract successful deployed diagram](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/qxvwv41zy1j9rzo3kzex.png) _You can check this deployed contract on chain at https://test.whatsonchain.com/tx/e39961a0f783cf4da7e24c7b9e0f3490e2444ef87d7c3b96fde6e732392f6184_ ## CREATE YOUR FRONTEND. 1. Create a react app named hello. Note that we are creating our frontend as "hello" not "helloworld" to prevent conflict in files like `package.json`, `node_modules` and `src files`. Run the following code: --- `npx create-react-app hello --template typescript` We will do most work under the src directory. Run the init command of the [CLI](https://docs.scrypt.io/installation#the-scrypt-cli-tool) to add sCrypt support in your project. `cd hello` `npx scrypt-cli init` This will install all the dependencies and configures the contract development environment in our react dApp. But you need to run `git add .` `git commit -m “Your commit message”` `git push` To commit your changes to master or main if you are working in git remote repository before you can run `“npx scrypt-cli init”` A successful initialization will give you “src/contracts/hello.ts” file in your react app as shown below: ![Diagram showing successful initialization of "src/contracts/hello.ts" in React App](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/ly590ijbk3rst0gjv1f3.png) 2. Load and Compile the smart contract in the dApp. Copy and paste “helloworld.ts” from the backend helloworld into the “src/contracts/hello.ts” in the front end “hello” directory. We will now compile the contract by running the following command: `npx scrypt-cli compile` A successful compilation will generate “artifacts/hello.json” file as shown below: ![Diagram showing successful generation of artifacts/hello.json file](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/4co1770s5d7s9yz0mm1e.png) We will now load the artifact file directly in the index.tsx file as shown below ``` import React from "react"; import ReactDOM from "react-dom/client"; import "./index.css"; import App from "./App"; import reportWebVitals from "./reportWebVitals"; import { Helloworld } from './contracts/helloworld'; //loading artifact //file import artifact from '../artifacts/helloworld.json'; Helloworld.loadArtifact(artifact); const message = toByteString('hello world', true) // creating instance //from contract class. const instance = new Helloworld(sha256(message)) const root = ReactDOM.createRoot( document.getElementById("root") as HTMLElement ); root.render( <React.StrictMode> <App /> </React.StrictMode> ); // If you want to start measuring performance in your app, pass a function // to log results (for example: reportWebVitals(console.log)) // or send to an analytics endpoint. Learn more: https://bit.ly/CRA-vitals reportWebVitals(); ``` Just like that we are done integrating our smart contract with the front end. We can now go further to customize the React dApp e.g by styling. ## INTEGRATE YOURS WALLET Follow this [link](https://docs.scrypt.io/advanced/how-to-add-a-signer) to integrate Yours Wallet formerly known as Panda Wallet. Request access to the wallet, by using the requestAuth method below: ``` const signer = new PandaSigner(provider); // request authentication const { isAuthenticated, error } = await signer.requestAuth(); if (!isAuthenticated) { // something went wrong, throw an Error with `error` message throw new Error(error); } // authenticated // you can show user's default address const userAddress = await signer.getDefaultAddress(); // ... ``` Now you can connect the wallet to the contract instance as before using the code below: ``` await instance.connect(signer); ``` The sample code use in this write up can be found in the [repository](https://github.com/Bravolakmedia/helloworld/tree/master) and the whole write up is a basic guide for creating a complete dApp on BSV blockchain using sCrypt-cli. ## REFERENCES. 1.

Nous sommes de retour des **VoxxedDays Luxembourg** et nous en profitons pour écrire cet article et établir notre top 3 des conférences que nous avons le plus appréciées durant ces deux jours. C'est aussi l'occasion de faire un peu d'auto-promotion car c'est la première fois que nous avons donné notre talk [Il faut sauver le dernier Giga de RAM](https://github.com/dlucasd/il-faut-sauver-le-dernier-giga-de-ram) en public avec [Ivan](@ibethus). Nous avions déjà eu l'occasion de le présenter chez **Onepoint** lors de nos [Sud-Ouest Days](https://www.groupeonepoint.com/fr/notre-actualite/atlantique-days-et-sud-ouest-days-une-mise-en-situation-complete-pour-nos-futurs-speakers/), un événement interne qui reprend le même processus de soumission des talks : _Call For Paper_ sous conference-hall.io, sélection du jury, et pour terminer, une journée banalisée regroupant généralement 8 conférences devant une cinquentaine de personnes. Notre talk est un retour d'expérience sur l'optimisation de la consommation mémoire sur une chaîne batch Java / Spring que nous avons dû effectuer fin d'année dernière. C'est un mélange de jeux de rôle, de trois démos en direct et, pour chacune, des slides récapitulatives pour retenir l'essentiel. Merci à toutes les personnes qui nous ont donné des retours que ce soit sur l'application Voxxrin, sur les réseaux ou en direct. Cela nous fait très plaisir. Les conditions pour présenter ce talk étaient excellentes, merci encore aux organisateurs des **VoxxedDays Luxembourg** pour leur accueil, leur bienveillance et tout le travail qui se cache derrière pour nous permettre de passer deux jours hors du commun. Enfin, merci à Onepoint et nos partners Sud-Ouest de nous permettre de vivre ces moments! ## Et si on implémentait une Machine à Etats from scratch pour aider la petite souris ? [Laurine Le Net](https://twitter.com/LaurineLeNet) se livre à une implémentation d'une machine à état à partir de zéro lors d'un live coding d'environ quarante minutes. Petit à petit, elle redéfinit chaque concept d'une machine à état et les implémente dans une stack Java et Spring. Le cas d'utilisation est très simple : aider la petite souris à avoir de l'observabilité et de la fiabilité lors de son workflow d'échange de dents contre de l'argent sous l'oreiller des enfants. Les slides sont claires, le métier est simple, le live coding se déroule rapidement, le tout ponctué de touches d'humour. Nous avons passé un bon moment avec [Ivan](@ibethus) à regarder cette conférence. Laurine termine en évoquant bien sûr les solutions du marché qui existent (telles que Spring Statemachine, ou encore Temporal et Camunda) mais c'est toujours intéressant de comprendre ce qu'il se passe sous le capot ! Les replays ne sont bien évidemment pas disponibles, mais vous pouvez déjà visionner ce talk qu'elle a donné au DevFest Lille. {% embed https://www.youtube.com/watch?v=1fYcpyArorI %}. ## Comment nous avons transformé les Restos du Cœur en Cloud Provider Les **Restos du Cœur** est sans doute l'association d'aide aux démunis la plus célèbre en France. Créée en 1985 par Coluche, elle compte désormais environ 2 000 membres et plus de 75 000 bénévoles. L'association est répartie sur 117 antennes départementales, ce qui pose évidemment problème au pôle en charge de l'informatique. En effet, comment connecter ces différents centres ? Comment créer et maintenir une infrastructure, fournir des services aux utilisateurs finaux, sans oublier que chez les Restos, chaque euro compte ? [Julien Briault](https://twitter.com/ju_hnny5) est ingénieur réseau SRE chez Deezer, mais s'occupe également bénévolement de l'infrastructure IT des restos du cœur. À travers sa conférence, il nous fait découvrir la transformation intervenue dans l'association, pour passer de systèmes informatiques vieillissants, hétérogènes et indépendants en véritable service cloud interne centralisé. Avec nombre d'anecdotes passionnantes, Julien détaille les défis d'une telle opération. On y apprend aussi bien les contraintes liées à une telle structure, que les détails de la stack technique retenue (OpenStack et Kubernetes) et de son implémentation. Sans oublier toute la partie hardware de _récup_. Pour les amoureux de l'open-source, du bénévolat et de la débrouille, cette conférence est un must ! P.S. les Restos recrutent (des bras et des développeurs) ## L'Indexation SQL au-delà des simples colonnes `select author from talks where content LIKE '%voxxedDays%'` Quelles performances pourrait-on attendre d'une requête comme celle-ci sur une base de données contenant plusieurs centaines de milliers voir millions d'entrées ? Grâce à [Franck Pachot](https://x.com/FranckPachot), peut-être qu'elles ne seraient pas si mauvaises. Cet expert en bases de données relationnelles propose à travers sa conférence une approche plus poussée des index, notamment sur la base de données **PostgreSQL**, mais aussi **Oracle**. Il explore plusieurs exemples d'indexation (expressions, fragments de texte, attributs JSON et requêtes _Top-N_) sur **PostgreSQL** (Expression index, Inverted index, Partial index, Covering index, Order preserving joins) et évalue l'efficacité de l'indexation en examinant les plans d'exécution. Conférence très technique mais néanmoins accessible et passionnante, on n'en ressort pas indemne. > Ai-je les bons index sur ma base ? > Pourrais-je optimiser les performances de cette requête dont le client se plaint depuis des mois ?! Franck a déjà donné ce talk à Devoxx France il y a quelques mois : {% embed https://www.youtube.com/watch?v=TW8qjs8D0Bk %}

Enterprise Resource Planning (ERP) systems are essential for managing business processes in organizations, providing integrated applications to manage and automate back-office functions. However, no ERP system can meet every unique need of an organization out-of-the-box. This is where customization comes into play. Customizing [ERP modules](https://www.impactfirst.co/id/erp/software-erp) using languages like Python and Ruby can offer flexibility and power to tailor ERP systems to specific business requirements. This article will guide you through the process of customizing ERP modules using Python and Ruby, covering key concepts, tools, and best practices. ## Understanding ERP Customization ERP customization involves modifying the existing ERP software to meet the unique needs of an organization. This can include adding new modules, altering existing functionalities, or integrating the ERP with other software systems. The customization can be done at various levels: - **User Interface (UI) Customization**: Changes in the appearance and navigation of the ERP system. - **Business Logic Customization**: Modifying the logic that governs business processes. - **Data Model Customization**: Adding new data fields or tables. - **Integration Customization**: Connecting the ERP system with other software applications. ## Why Python and Ruby? Python and Ruby are popular programming languages known for their simplicity, readability, and powerful libraries, making them ideal choices for ERP customization. Here's why they stand out: - **Python**: - Extensive libraries and frameworks (e.g., Django, Flask). - Easy to learn and use, which accelerates development. - Excellent for data manipulation and automation tasks. - **Ruby**: - Known for its elegant syntax which makes the code more readable. - Ruby on Rails, a powerful web application framework, simplifies database integration and management. - Strong community support and numerous gems (libraries) to extend functionality. ## Setting Up Your Environment Before diving into customization, you need to set up your development environment. 1. **Install Python or Ruby**: - For Python: Download and install the latest version from the [official Python website](https://www.python.org/). - For Ruby: Download and install the latest version from the [official Ruby website](https://www.ruby-lang.org/). 2. **Set Up an Integrated Development Environment (IDE)**: - Python: PyCharm, Visual Studio Code. - Ruby: RubyMine, Visual Studio Code. 3. **Install ERP System SDKs and Libraries**: - Python: Libraries like `pandas`, `sqlalchemy` for data manipulation, and ERP-specific SDKs. - Ruby: Gems like `activerecord` for database interactions and ERP-specific libraries. ## Customizing ERP Modules with Python **Example**: Adding a Custom Report Module in Odoo Odoo is a popular open-source ERP system written in Python. 1. **Create a Custom Module**: - Navigate to the Odoo add-ons directory and create a new directory for your module. - Inside your module directory, create the `__init__.py` and `__manifest__.py` files. 2. **Define the Module Manifest**: ```python { 'name': 'Custom Sales Report', 'version': '1.0', 'author': 'Your Name', 'category': 'Sales', 'depends': ['base', 'sale'], 'data': [ 'views/custom_sales_report_view.xml', 'reports/custom_sales_report_template.xml', ], } ``` 3. **Create Business Logic**: - Define a new Python class for your custom report in a new file, e.g., `custom_sales_report.py`. ```python from odoo import models, fields, api class CustomSalesReport(models.Model): _name = 'custom.sales.report' _description = 'Custom Sales Report' date_from = fields.Date(string='Start Date') date_to = fields.Date(string='End Date') @api.multi def generate_report(self): # Custom logic to generate the report sales_orders = self.env['sale.order'].search([ ('date_order', '>=', self.date_from), ('date_order', '<=', self.date_to), ]) # Process the data and generate the report ``` 4. **Create XML Files for Views and Reports**: - Define the views and report templates in XML files (`custom_sales_report_view.xml` and `custom_sales_report_template.xml`). 5. **Install and Test Your Module**: - Update the app list in Odoo and install your custom module. - Test the module by navigating to the relevant section in Odoo and verifying the functionality. ## Customizing ERP Modules with Ruby **Example**: Adding a Custom Inventory Report in Spree Spree is an open-source e-commerce platform built with Ruby on Rails, often used as part of an ERP solution. 1. **Create a Custom Extension**: - Use the Spree extension generator to create a new extension. ``` rails generate spree:extension custom_inventory_report ``` 2. **Define the Extension**: - Navigate to the newly created extension directory and define your extension in `lib/spree/custom_inventory_report/engine.rb`. 3. **Add Business Logic**: - Create a new Ruby class for your custom report, e.g., `custom_inventory_report.rb`. ```ruby module Spree class CustomInventoryReport def initialize(start_date, end_date) @start_date = start_date @end_date = end_date end def generate_report inventory_items = Spree::InventoryItem.where('created_at >= ? AND created_at <= ?', @start_date, @end_date) # Process the data and generate the report end end end ``` 4. **Create Views and Templates**: - Define the views and templates for the custom report in the appropriate directories. 5. **Integrate and Test Your Extension**: - Mount the extension in your Rails application by adding it to the `Gemfile` and running the necessary migrations. - Test the functionality by accessing the custom report through the Spree admin interface. #### Best Practices for ERP Customization 1. **Modular Approach**: Keep customizations modular to simplify maintenance and upgrades. 2. **Documentation**: Thoroughly document customizations to ensure future developers can understand and extend your work. 3. **Testing**: Implement robust testing (unit, integration, and functional tests) to ensure customizations work as expected. 4. **Version Control**: Use version control systems (e.g., Git) to manage changes and collaborate with other developers. 5. **Performance Optimization**: Monitor the performance of custom modules and optimize queries and logic to prevent system slowdowns. ## Conclusion Customizing ERP modules using Python or Ruby allows you to tailor the system to meet your specific business needs. By leveraging the power of these programming languages and following best practices, you can enhance the functionality of your [ERP system](https://www.impactfirst.co/id/c/software-erp), streamline business processes, and improve overall efficiency. Whether you are adding new features, integrating with other systems, or optimizing existing processes, Python and Ruby provide the tools and flexibility needed to make your ERP system truly work for you.

This data can be text, image, audio, or video. In this beginner guide, we'll be exploring vector embeddings in more detail. ## What are Vector Embeddings? What is vector embedding? Vector embeddings are the building blocks of many natural language processing (NLP), recommendation, and [vector search](https://docs.pieces.app/build/glossary/terms/vector-search) algorithms. The day-to-day tools you use, like AI assistants, voice assistants, language translators, or any recommendation tool, are working efficiently due to embeddings. Vector embeddings are like a special method that turns words, sentences, images, and other data into numbers. These numbers show what data mean and how they relate to each other. Imagine these numbers as points on a map where similar things are close together. This helps computers understand and work with the information more easily. Vector embeddings represent words or documents as vectors in a multi-dimensional space. Each dimension in the vector space captures different aspects of the semantic meaning of the word or document. For example, in word embeddings trained using techniques like Word2Vec or GloVe, each dimension may correspond to a specific semantic feature such as gender, tense, or sentiment. <figure><img src="https://d37oebn0w9ir6a.cloudfront.net/account_32099/image4_35cc2564a6cf0a1b951fb4b5b8a2e48b.png" alt="A flowchart representation of how queries and training materials are transformed into vectors."/></figure> Some of the different types of embeddings commonly used in various applications are: - **Word Embeddings:** These embeddings represent individual words as vectors in a multi-dimensional space, capturing their semantic meanings and relationships with other words. Word2Vec, GloVe, and FastText are common techniques used to generate word embeddings. - **Document Embeddings:** Document embeddings represent entire documents or paragraphs as vectors. Techniques like Doc2Vec and averaging word embeddings are often used to create document embeddings. - **Sentence Embeddings:** Similar to document embeddings, sentence embeddings represent individual sentences as vectors. They are useful for tasks like sentence similarity and sentiment analysis. - **Image Embeddings:** In computer vision, images can be represented as vectors using techniques like convolutional neural networks (CNNs). These embeddings capture the visual features of images and are used in tasks like image classification and object detection. These are just a few examples of vector embeddings, and new techniques are constantly being developed to address specific use cases and improve performance in various applications. Some more types are knowledge graph embeddings, entity embeddings, audio embeddings, etc. ## The Mathematics Behind Vector Embeddings, Explained The mathematics behind vector embeddings vary depending on the application, but several mathematical and machine learning concepts and techniques are commonly used when creating them. For example: - Vector Space Model (VSM) - Word Embedding Algorithms (Word2Vec & GloVe) - Neural Networks - Dimensionality Reduction - Distance Metrics - Optimization Techniques (SGD) - BERT Last but not least, as the term suggests, "vector embeddings" are related to vectors. In math, a vector is a set of numbers representing both magnitude and direction. It's like an arrow pointing from the origin to a specific point in space. <figure><img src="https://d37oebn0w9ir6a.cloudfront.net/account_32099/image6_d2bd050b74e2aae7d619760f718f11e8.jpg" alt="The vector at 1,1."/></figure> As developers, we can think of vectors as arrays with numerical values. In a space filled with vectors, some are close, others distant, and some cluster together while others are scattered. These models, often created with neural networks and labeled data, can handle even high-dimensional vectors that are hard to visualize. In machine learning, these multi-dimensional vectors are like magic, helping us solve various problems, from finding similar items online to organizing data effectively. <figure><img src="https://d37oebn0w9ir6a.cloudfront.net/account_32099/image5_d8d9bbd575dfd0e3ba039eed6c649a7e.jpg" alt="Several vectors on a 4-quadrant graph."/></figure> Vectors are essential for machine learning, but transforming data into vectors isn't straightforward. We need embedding models (like Word2Vec, BERT & GloVe) to maintain the meaning of the original data. ML algorithms require numerical data to function. We use vector embeddings, which are lists of numbers, to represent various types of data, including audio files or text documents. This allows us to perform operations on them efficiently, simplifying tasks such as analyzing text or processing audio data. Vector space models are mathematical frameworks used to represent objects or concepts as vectors in a high-dimensional space, sometimes in a vector database. <figure><img src="https://d37oebn0w9ir6a.cloudfront.net/account_32099/image3_9bbeb1c9e6c00fca4d6959941955d1a3.jpg" alt="A visualization of objects going through an embedding model to become vectors."/></figure> Vector embeddings play a crucial role in capturing semantic information from textual data. One of the key applications of vector embeddings is measuring semantic similarity between words, phrases, or documents. Semantic similarity refers to the degree of closeness or resemblance in meaning between two vectors. To measure the similarity between two vectors, the cosine similarity formula is commonly used. It calculates the cosine of the angle between the vectors, which represents their direction in multi-dimensional space. The formula for cosine similarity between two vectors `a` and `b` is given by: <figure><img src="https://d37oebn0w9ir6a.cloudfront.net/account_32099/image1_e99322cb692a34b945bb9dc25727ab15.png" alt="cosine_similarity(a,b) = (a*b)/(||a||*||b||)."/></figure> Where, - `a` and `b` are the two vectors we want to compare. - `•` represents the dot product operation, which calculates the sum of the products of corresponding elements between the two vectors. - `||a||` and `||b||` represent the magnitude (length) of vectors `a` and `b`, respectively. Cosine similarity outputs a value between `-1` and `1`. A value of `1` indicates perfect similarity (vectors pointing in the same direction), `0` indicates no correlation (vectors are orthogonal), and `-1` signifies perfect dissimilarity (vectors pointing in opposite directions). By calculating cosine similarity between vector representations of words, sentences, or even documents, machine learning models can perform tasks like recommendation, identification, and grouping based on the closest semantic meaning. ## Applications of Vector Embeddings Vector embeddings create efficient data representations because they provide a way to represent complex and high-dimensional data in a simpler format essential for processing and analyzing large datasets effectively. Embeddings significantly enhance machine learning model performance by allowing them to understand data nuances and relationships, particularly in text analysis. They enable complex tasks like natural language processing and image recognition by converting raw data into a suitable format for algorithms. Moreover, embeddings help build advanced recommendation systems for personalized suggestions and facilitate data visualization and clustering. Additionally, they enable innovative approaches such as [cross-modal search](https://docs.pieces.app/features/search-modes) and retrieval by bridging different data types. Vector embeddings have a wide range of applications across various fields. Let's explore a few of them in more detail: 1. **Natural Language Processing (NLP):** Vector embeddings are crucial for tasks like sentiment analysis, [question answering](https://code.pieces.app/blog/question-answering-on-source-code-repositories), [neural machine translation](https://docs.pieces.app/build/glossary/terms/neural-machine-translation), and other tasks that demand efficient processing of textual data, such as [NLP chatbots](https://code.pieces.app/blog/nlp-chatbots-an-overview-of-natural-language-processing-in-chatbot-technology). 1. **Personalized Recommendation Systems:** Vector embeddings power recommendation systems by capturing user preferences and item characteristics, leading to tailored content suggestions, as seen in platforms like Netflix. 1. **Visual Content Analysis:** Vector embeddings enhance image classification, object detection, and similarity searches, contributing to advancements in image recognition technologies like Google Lens. 1. **Anomaly Detection:** Utilizing embeddings, anomaly detection algorithms identify unusual patterns in various data types, aiding in cybersecurity applications by detecting deviations from normal behavior. 1. **Search Engines:** Vector embeddings power semantic search capabilities in search engines such as Pieces’ [Global Search](https://docs.pieces.app/features/global-search), allowing for relevant web page retrieval, spelling correction, and related query suggestions based on semantic relationships. From a developer's perspective, the challenge often lies in efficiently handling unstructured data. Traditional applications rely on structured data represented as objects with properties, which may grow over time. As these objects become "fat" with numerous properties, selecting essential features becomes vital for optimal application performance. This process, known as feature engineering, involves creating specialized representations of objects tailored to specific tasks. However, when dealing with unstructured data like text or images, manual feature engineering becomes impractical due to the abundance of relevant features. In such cases, vector embeddings offer an automated solution. Instead of manually selecting features, developers can utilize pre-trained machine learning models to generate compact representations of the data while preserving its meaningful characteristics. This approach streamlines the handling of unstructured data, allowing developers to extract valuable insights without extensive manual intervention. ## How to Create Embeddings We will be using the Hugging Face[ sentence-transformers](https://www.sbert.net/) model[ all-MiniLM-L6-v2](https://huggingface.co/sentence-transformers/all-MiniLM-L6-v2) to create sentence embeddings. `all-MiniLM-L6-v2` is a pre-trained model available in the Sentence Transformers library, which is built on top of the Hugging Face Transformers library. It provides a high-level API for generating sentence embeddings using pre-trained transformer models from the Hugging Face Model Hub. The `all-MiniLM-L6-v2` model is based on the MiniLM architecture, which is a smaller and faster version of the popular BERT architecture. This model maps sentences & paragraphs to a 384-dimensional dense vector space and can be used for tasks like clustering or semantic search. Let's create sentence embeddings! **Step 1:** Install the Sentence Transformers library: ``` pip install sentence-transformers ``` **Step 2:** Import the SentenceTransformer class: ``` from sentence_transformers import SentenceTransformer ``` **Step 3:** Load a pre-trained model: ``` model = SentenceTransformer('all-MiniLM-L6-v2') ``` **Step 4:** Generate embeddings for some example sentences: ``` sentences = ['You are reading Pieces Blog.', 'You are using the right tool.'] embeddings = model.encode(sentences) ``` **Step 5:** Print the generated sentence embeddings: ``` print(embeddings) ``` <figure><img src="https://d37oebn0w9ir6a.cloudfront.net/account_32099/image2_559a812be3fb4bfbeb53a20142d833cd.png" alt="The vector embeddings of the input sentence above."/></figure> As you can see in the above image output, you've successfully generated sentence embeddings using the Sentence Transformers library. The output is a NumPy array of shape `(2, 384)`, meaning each of the resulting sentence embeddings has 384 dimensions and each row corresponds to a sentence embedding. ## Conclusion With the increasing use and development of AI, vector embeddings are going to be widely used in various applications in the ML field. Vector embeddings are a very powerful and important tool for developers to work with complex data. Any AI apps you use or see work effectively due to vector embeddings. Vector embeddings are widely used in Pieces for Developers too; for example, you can check our [state-of-the-art OCR](https://code.pieces.app/blog/top-ocr-tools) feature that [extracts code from images](https://pieces.app/features/extract). Text embeddings are used to provide better code suggestions and explanations, among many other features.

## Adding Plyr to Custom HTML5 Video with Additional Features #### Introduction Plyr is a lightweight, accessible, and customizable media player for the web that supports HTML5 video, audio, and YouTube. This article will guide you through the process of integrating Plyr into your custom HTML5 video setup, including additional features like customizing the skin and adding a download button. {% youtube https://www.youtube.com/watch?v=SR8pFHpsC8c&ab_channel=ShadeTech %} > https://github.com/techshade/how-to/blob/main/plyr/adding-plyr-to-html5-video-player.md #### Prerequisites Before starting, ensure you have basic knowledge of HTML, CSS, and JavaScript. You'll also need a code editor and a web browser for testing. #### Step-by-Step Guide ##### Step 1: Set Up Your Project Create a project directory and set up your HTML file. ```plaintext project-directory/ ├── index.html └── css/ └── styles.css └── js/ └── scripts.js ``` ##### Step 2: Include Plyr CSS and JavaScript Plyr can be included via a CDN for ease of use. Add the following lines to the `<head>` section of your `index.html` file. ```html <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Custom HTML5 Video with Plyr</title> <!-- Plyr CSS --> <link rel="stylesheet" href="https://cdn.plyr.io/3.7.2/plyr.css" /> <!-- Your custom CSS --> <link rel="stylesheet" href="css/styles.css"> </head> <body> ``` Add the Plyr JavaScript at the end of the `<body>` section, along with your custom JavaScript file. ```html <!-- Your custom JavaScript --> <script src="js/scripts.js"></script> <!-- Plyr JavaScript --> <script src="https://cdn.plyr.io/3.7.2/plyr.js"></script> </body> </html> ``` ##### Step 3: Add HTML5 Video Element In the body of your HTML file, add a video element with custom attributes. ```html <body> <video id="player" playsinline controls> <source src="path/to/your/video.mp4" type="video/mp4" /> <!-- Add more sources if needed --> </video> </body> ``` ##### Step 4: Initialize Plyr Now, initialize Plyr in your `scripts.js` file. This will replace the standard video player with Plyr's player. ```javascript document.addEventListener('DOMContentLoaded', () => { const player = new Plyr('#player'); }); ``` ##### Step 5: Customize Plyr Controls Plyr offers extensive customization options. For instance, you can customize the controls by passing an options object when initializing Plyr. ```javascript document.addEventListener('DOMContentLoaded', () => { const player = new Plyr('#player', { controls: [ 'play-large', // The large play button in the center 'restart', // Restart playback 'rewind', // Rewind by the seek time (default 10 seconds) 'play', // Play/pause playback 'fast-forward', // Fast forward by the seek time (default 10 seconds) 'progress', // The progress bar and scrubber for playback and buffering 'current-time', // The current time of playback 'duration', // The full duration of the media 'mute', // Toggle mute 'volume', // Volume control 'captions', // Toggle captions 'settings', // Settings menu 'pip', // Picture-in-picture (currently Safari only) 'airplay', // Airplay (currently Safari only) 'fullscreen' // Toggle fullscreen ], settings: ['captions', 'quality', 'speed', 'loop'], }); }); ``` ##### Step 6: Add Custom CSS (Optional) To style the Plyr player or adjust your page layout, you can add custom CSS in `styles.css`. ```css body { font-family: Arial, sans-serif; margin: 0; padding: 0; display: flex; justify-content: center; align-items: center; height: 100vh; background-color: #f0f0f0; } #player { width: 80%; max-width: 800px; } ``` ##### Step 7: Adding a Download Button To add a custom download button, we need to extend the Plyr controls and add some custom JavaScript. Modify your Plyr initialization code in `scripts.js`: ```javascript document.addEventListener('DOMContentLoaded', () => { const player = new Plyr('#player', { controls: [ 'play-large', // The large play button in the center 'restart', // Restart playback 'rewind', // Rewind by the seek time (default 10 seconds) 'play', // Play/pause playback 'fast-forward', // Fast forward by the seek time (default 10 seconds) 'progress', // The progress bar and scrubber for playback and buffering 'current-time', // The current time of playback 'duration', // The full duration of the media 'mute', // Toggle mute 'volume', // Volume control 'captions', // Toggle captions 'settings', // Settings menu 'pip', // Picture-in-picture (currently Safari only) 'airplay', // Airplay (currently Safari only) 'download', // Custom download button 'fullscreen' // Toggle fullscreen ], settings: ['captions', 'quality', 'speed', 'loop'], }); // Adding event listener to the custom download button const downloadButton = document.createElement('button'); downloadButton.classList.add('plyr__control'); downloadButton.innerHTML = '<svg role="presentation" focusable="false"><use xlink:href="#plyr-download"></use></svg>'; downloadButton.addEventListener('click', () => { const videoSrc = document.querySelector('#player source').src; const a = document.createElement('a'); a.href = videoSrc; a.download = 'video.mp4'; document.body.appendChild(a); a.click(); document.body.removeChild(a); }); // Insert the download button before the fullscreen button const controls = player.elements.controls; const fullscreenButton = controls.querySelector('.plyr__control--fullscreen'); controls.insertBefore(downloadButton, fullscreenButton); }); ``` ##### Step 8: Customize the Skin To customize the skin of Plyr, you can override the default CSS rules in `styles.css`. ```css /* Change the color of the play button */ .plyr--full-ui .plyr__control--overlaid { background: #1e90ff; } /* Customize the progress bar */ .plyr--full-ui .plyr__progress__container { background: #d3d3d3; } .plyr--full-ui .plyr__progress__buffer { background: #a9a9a9; } .plyr--full-ui .plyr__progress__played { background: #1e90ff; } ``` #### Conclusion You have successfully integrated Plyr into your custom HTML5 video setup, customized the controls, added a download button, and customized the skin. Plyr provides a sleek, consistent, and feature-rich media player that enhances the user experience. For more advanced configurations and updates, refer to the official [Plyr documentation](https://github.com/sampotts/plyr). By following this guide, you can provide a highly customizable and user-friendly video playback experience on your website. --- ### Useful Links - https://codexdindia.blogspot.com/2021/05/plyrio-video-player-integration-skin-Customizing-and-Adding-Download-Button-to-plyr.html - https://dev.to/sh20raj/sample-videos-for-testing-4a30

When you're starting out, it's easy to just fly by the seat of your pants. A blog here, a social post there. You write some, your engineers or community members write some. Good, you're starting. And part of that is just doing. But then, you get funding. Hire some folks. Start to coordinate efforts. ## 👽 YOU NEED A CONTENT MANAGER 👽 Leaving this up to yourself or your engineers creates disorganized and, thus, ineffective efforts. It's all wasted if it's not coordinated from ideation to writing and editing to final reviews and publishing. I did this for Red Hat's Opensource.com site for 10 years and genuinely love bringing the process to teams and companies. Startups especially need this process and strategy as they get things up and running for the first time, but all companies can benefit from a content or marketing reset or refresh. Times in tech have been especially hard with layoff after layoff, particularly impacting marketing-content-community teams. But one thing I've learned over the years, engineers cannot make it in the game of business without us. You may have figured out how to engineer software to solve an important problem, but if you don't set up your show-and-tell side of the house with some serious know-how and process, it will all fall by the wayside... getting you nowhere fast. Why does this matter? Competition is fierce. And what I can promise you is that you don't really understand how the following works well enough to do it yourself: - write compelling content consistently (nailing the tone, audience, links) - pitch your content and company (to publications, podcasts, webinars) - create and maintain partnerships with similar businesses/integrations (co-webinars/gigs/blogs) - manage your community of customers and contributors (real engagement with real humans overtime that makes an impact) I highly recommend you read [this article](https://plane.so/blog/how-we-got-to-20k-github-stars) by the team at Plane. ## ⚡️ YOU NEED A 30-60-90 DAY CONTENT STRATEGY PLAN ⚡️ Here's how it works: 🎧 [Get on a call with an expert](https://paperbell.me/jen-wike-huger) about where you are on your journey regarding content, customers, and community. Doesn't have to be a big deal. They ask the questions, you just give the real answers. ✍ They go back to their desk to make a plan. This is my 4-step process. 1️⃣ Review and research any materials you've shared with me, your website and other content, your audience and industry... all that good stuff. 2️⃣ Create a 30-60-90 day content strategy plan (or general marketing plan). 3️⃣ Add a healthy dose of structure and process: I build content calendars and editorial workflows for you. 4️⃣ Delivery! You and your team are set up to execute a stellar new content plan.

<div>I was left with just 0.15% of my own VC-backed Startup.</div><div><br></div><div>(may happen to anyone).</div><div><br></div><div>In 2013, I worked as a part-time CTO in several software startups in a startup incubator.</div><div><br></div><div>On one of the “Friday beer” evenings, I was approached by a huge old man.&nbsp;</div><div><br></div><div>He broke the ice, touched my shoulder, and behaved like we were old friends. He knew who I was and made me feel so safe.</div><div><br></div><div>It all looked random to me, but it wasn’t.</div><div>Years later, he revealed: “I moved into this incubator because I wanted to hire you.”</div><div>CoFounder</div><div>He was about to start a hardware startup, a hardware product that looked like it was made by Apple.</div><div><br></div><div>This idea felt so compelling (compared to easy software tools I worked on) that I had no doubt and joined him as a CTO and CoFounder. I got 15% of the company.</div><div>Rich Man</div><div>He was a rich man with a huge house in the city's best luxury area and a big exit in the past.</div><div>He kept saying: “I can’t do this without you..”. He was a master of psychology, and I'd do anything for him, he was my mentor, like a father.</div><div><br></div><div>I did my best job ever, working days and nights and sleeping on the office couch with 20-hour shifts.&nbsp;</div><div>We had lots of orders, and I was putting the software and hardware together, driving it to the clients, and installing it.&nbsp;</div><div><br></div><div>I was obsessed; My girlfriend left me because we didn’t see each other. I would be home when she was asleep and leave before she woke up.</div><div>Equity</div><div>Whenever we hired someone, the founder would give them equity, and I asked him why he gave out equity so easily. He said: I know how to return it back when needed.&nbsp;</div><div>I didn't get what he meant, but I learned this in a very painful way later, that I'll share at the end of the story.</div><div><br></div><div>Living A Dream</div><div>Things were going really well,</div><div>We met Jack Dorsey (founder of Twitter and Square) in SF and presented our machine. We partnered with his company, which was making the payment stands, to use them for our machine. Lots of doors were open. We raised money from investors and got into the best B2B accelerator in the world, Silicon Valley.</div><div>Break up</div><div>While things were going really well, I engaged with a new girl. She got pregnant while studying in Norway.</div><div>I was traveling between SF and Oslo, and it was too difficult while having an infant.</div><div><br></div><div>I felt like I had no control over my life.&nbsp;</div><div>I had to fly to meet partners, VCs, and a co-founder. Everything was on their terms, so I had to adapt.</div><div>It all led to me breaking up with the girl. My life was a mess, and I couldn't move to SF because it meant I couldn't see my kid.</div><div><br></div><div>I decided to leave the startup. I spent a year hiring more people, delegating, and finding a new guy to replace me as CTO. The replacement went very well, so eventually, I left, and the company did great without me.</div><div><span style="background-color: rgba(31,41,55,var(--tw-bg-opacity)); font-size: 1.125rem; color: rgba(255,255,255,var(--tw-text-opacity)); font-family: inherit;">Poor Founder Risk</span><br></div><div>I moved on with my new startup, but a few months later, I got an email from the board. They were planning a new funding round, which looked good to me. So, at first, I was happy about that; it meant my shares would be worth more.</div><div><br></div><div>But it turned out they were planning an internal downturn, in which all investors had to contribute because they had inflated the expenses so much that the company needed an urgent investment.</div><div>I was the only shareholder who wasn't rich.</div><div>It was relatively little money for all the investors, but for me, it was more than I could afford. Since I owned 15% and couldn’t participate in the round, my 15% was diluted to 0.15%.</div><div><br></div><div>Why?</div><div><br></div><div style="border-color: rgba(229,231,235,var(--tw-border-opacity)); --tw-border-spacing-x: 0; --tw-border-spacing-y: 0; --tw-translate-x: 0; --tw-translate-y: 0; --tw-rotate: 0; --tw-skew-x: 0; --tw-skew-y: 0; --tw-scale-x: 1; --tw-scale-y: 1; --tw-pan-x: ; --tw-pan-y: ; --tw-pinch-zoom: ; --tw-scroll-snap-strictness: proximity; --tw-gradient-from-position: ; --tw-gradient-via-position: ; --tw-gradient-to-position: ; --tw-ordinal: ; --tw-slashed-zero: ; --tw-numeric-figure: ; --tw-numeric-spacing: ; --tw-numeric-fraction: ; --tw-ring-inset: var(--tw-empty, ); --tw-ring-offset-width: 0px; --tw-ring-offset-color: #fff; --tw-ring-color: rgba(59, 130, 246, 0.5); --tw-ring-offset-shadow: 0 0 #0000; --tw-ring-shadow: 0 0 #0000; --tw-shadow: 0 0 #0000; --tw-shadow-colored: 0 0 #0000; --tw-blur: ; --tw-brightness: ; --tw-contrast: ; --tw-grayscale: ; --tw-hue-rotate: ; --tw-invert: ; --tw-saturate: ; --tw-sepia: ; --tw-drop-shadow: ; --tw-backdrop-blur: ; --tw-backdrop-brightness: ; --tw-backdrop-contrast: ; --tw-backdrop-grayscale: ; --tw-backdrop-hue-rotate: ; --tw-backdrop-invert: ; --tw-backdrop-opacity: ; --tw-backdrop-saturate: ; --tw-backdrop-sepia: ; --tw-border-opacity: 1;">It turns out that in a VC-funded startup, it’s very easy to lose all almost your equity if the startup decides to have an internal round and issue new shares. It may have 100 shares, I own 15 and others own 85. Then it may issue 1000 shares, where each costs 10k. So I’d have to put 150k to stay with my 15%. (the numbers aren’t real, just for an example).

Doctrine is a powerful Object-Relational Mapper (ORM) for PHP, widely used in the Symfony framework but versatile enough to integrate with various other PHP applications. Personally, I use it with the PHP framework Nette which is widely used in Czechia where I'm based. Here are three reasons why I love Doctrine: ## 1. Handling Database Entities as Objects One of the most compelling reasons I use Doctrine is its ability to handle database entities as objects. This object-oriented approach to database interaction offers several advantages: **Simplified Code**: With Doctrine, I can work with database records as if they were regular PHP objects. This eliminates the need for complex SQL queries and instead, I define entities as classes and map them to database tables. This not only makes my code more readable but also reduces the likelihood of SQL injection attacks. **Seamless Data Manipulation**: Doctrine allows for seamless data manipulation through methods on entity objects. For example, instead of writing an SQL query to update a record, I can simply modify the properties of an entity and persist the changes. This abstraction layer makes my code cleaner and more maintainable. **Relationships Management**: Handling relationships between entities (like one-to-many, many-to-many, one-to-one, etc.) becomes really straightforward with Doctrine. By defining relationships in my entity classes, I can effortlessly navigate between related records, making my data model more intuitive and reflective of the actual business logic. ## 2. Events Doctrine's event system is another feature that significantly enhances its flexibility and power. Events in Doctrine allow me to hook into the lifecycle of an entity and perform operations at specific points in time. Doctrine provides a set of predefined events such as `prePersist`, `postPersist`, `preUpdate`, and `postUpdate`. These events give me hooks to execute custom logic before or after an entity is persisted, updated, or removed. This is particularly useful for tasks like logging changes, sending notifications, or validating data before database operations. For example, I use events for `createdAt` and `updatedAt` parameters. This way I can keep the business logic decoupled from the entity operations. This separation of concerns leads to a more modular and maintainable codebase, as my entities remain focused on data representation while the event listeners handle additional logic. ## 3. Command Line Interface (CLI) Doctrine's CLI is a powerful tool that streamlines database management tasks and provides numerous commands that simplify the development process. Creating, updating, or removing entities has never been easier and it saves me a lot of time. ## Conclusion Doctrine’s ability to handle database entities as objects, its powerful event system, and its comprehensive CLI tools make it an exceptional ORM for PHP developers. I cannot imagine a development without Doctrine anymore. Its features not only enhance my productivity but also contribute to writing clean, maintainable, and efficient code. Whether I am building a small application or a large enterprise system, Doctrine provides the tools and flexibility needed to manage my database interactions effectively. Do you use Doctrine in your projects? And why?

I heard some colleagues talking about gRPC framework and its benefits and advantages regarding Rest, so I dig a little in the gRPC world and its concepts to learn new ways to develop an API. ### What is gRPC? gRPC is an open-source API architecture and system. It’s based on the Remote Procedure Call (RPC) model. While the RPC model is broad, gRPC is a specific implementation. gRPC is a system that implements traditional RPC with several optimizations. For instance, gRPC uses Protocol Buffers and HTTP 2 for data transmission. It also abstracts the data exchange mechanism from the developer. ### gRPC vs REST The following image compares the basics of REST APIs and gRPC: ![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/2egdqgsezavydvnc7dx2.png) ## Implementation To better learn the gRPC concepts, I created a simple chat room scenario. #### Project Setup We'll create two projects within a solution: - ChatAppServer: The gRPC server that handles chat room logic. - ChatAppClient: The client application that users will run to join chat rooms and send messages (This is a console App project). Then we'll install the following nuget packages: - Grpc.AspNetCore - Grpc.Tools - Grpc.AspNetCore.Server.ClientFactory (this one only on the ChatAppClient project) #### Proto file We'll need to create a '.proto' file to define the gRPC service. This file specifies the service methods and message types. This is my chat.proto file: ``` syntax = "proto3"; option csharp_namespace = "ChatApp"; package chat; service ChatService { rpc JoinRoom (JoinRoomRequest) returns (JoinRoomResponse); rpc SendMessage (SendMessageRequest) returns (SendMessageResponse); rpc ReceiveMessages (ReceiveMessagesRequest) returns (stream ChatMessage); } message JoinRoomRequest { string username = 1; string room = 2; } message JoinRoomResponse { bool success = 1; } message SendMessageRequest { string username = 1; string room = 2; string message = 3; } message SendMessageResponse { bool success = 1; } message ReceiveMessagesRequest { string room = 1; } message ChatMessage { string username = 1; string message = 2; int64 timestamp = 3; } ``` **We have to include the .proto file on the .csproj so we can enable the code generator**, so on the ChatAppServer.csproj file add the following: ``` <ItemGroup> <Protobuf Include="Protos\chat.proto" GrpcServices="Server" /> </ItemGroup> ``` And on the ChatAppClient.csproj add the following: ``` <ItemGroup> <Protobuf Include="Protos\chat.proto" GrpcServices="Client" /> </ItemGroup> ``` After this, if we clean, restore and build the projects, the code will be generated and you can check it out on the path "obj\Debug\net6.0\Protos". #### Implement the server In the server project, implement the ChatService. ``` using System; using System.Collections.Concurrent; using System.Collections.Generic; using System.Threading.Tasks; using ChatApp; using Grpc.Core; using Microsoft.Extensions.Logging; namespace ChatAppServer.Services { public class ChatServiceImpl : ChatService.ChatServiceBase { private static readonly ConcurrentDictionary<string, List<IServerStreamWriter<ChatMessage>>> _rooms = new ConcurrentDictionary<string, List<IServerStreamWriter<ChatMessage>>>(); public override Task<JoinRoomResponse> JoinRoom(JoinRoomRequest request, ServerCallContext context) { if (!_rooms.ContainsKey(request.Room)) { _rooms[request.Room] = new List<IServerStreamWriter<ChatMessage>>(); } return Task.FromResult(new JoinRoomResponse { Success = true }); } public override Task<SendMessageResponse> SendMessage(SendMessageRequest request, ServerCallContext context) { if (_rooms.TryGetValue(request.Room, out var clients)) { var message = new ChatMessage { Username = request.Username, Message = request.Message, Timestamp = DateTimeOffset.UtcNow.ToUnixTimeSeconds() }; foreach (var client in clients) { client.WriteAsync(message); } } return Task.FromResult(new SendMessageResponse { Success = true }); } public override async Task ReceiveMessages(ReceiveMessagesRequest request, IServerStreamWriter<ChatMessage> responseStream, ServerCallContext context) { if (_rooms.TryGetValue(request.Room, out var clients)) { clients.Add(responseStream); try { await Task.Delay(Timeout.Infinite, context.CancellationToken); } finally { clients.Remove(responseStream); } } } } } ``` And we need to add the following on the Progra.cs file: ``` builder.Services.AddGrpc(); app.MapGrpcService<ChatServiceImpl>(); ``` #### Implement the client Modify the Program.cs file of the client project: ``` using System; using System.Threading.Tasks; using Grpc.Net.Client; using ChatApp; using Grpc.Core; class Program { static async Task Main(string[] args) { // Create a channel to the gRPC server var channel = GrpcChannel.ForAddress("https://localhost:7187"); var client = new ChatService.ChatServiceClient(channel); Console.WriteLine("Enter your username:"); var username = Console.ReadLine(); Console.WriteLine("Enter the room you want to join:"); var room = Console.ReadLine(); // Join the specified room var joinResponse = await client.JoinRoomAsync(new JoinRoomRequest { Username = username, Room = room }); if (joinResponse.Success) { Console.WriteLine($"Joined room: {room}"); } else { Console.WriteLine("Failed to join room"); return; } // Task for receiving messages var receiveTask = Task.Run(async () => { using var call = client.ReceiveMessages(new ReceiveMessagesRequest { Room = room }); await foreach (var message in call.ResponseStream.ReadAllAsync()) { Console.WriteLine($"[{message.Username}] {message.Message}"); } }); // Loop to send messages while (true) { var message = Console.ReadLine(); if (message.ToLower() == "exit") break; var sendMessageResponse = await client.SendMessageAsync(new SendMessageRequest { Username = username, Room = room, Message = message }); if (!sendMessageResponse.Success) { Console.WriteLine("Failed to send message"); } } // Wait for the receiving task to complete await receiveTask; } } ``` ## Running the application Use the **dotnet run** command to run the projects. Open 2 terminals of clients to interact with each other. ![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/2j6vq2nrz2bsxzi3recj.png) ![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/awbctzuv8ufntv8r8hw3.png) ## Conclusion This is still a very simple case of implementing gRPC framework to develop an API, and I still have a lot to work on and learn about this, I'm very excited! And that's it guys, I hope you liked it, stay tuned for more!

django, astrojs, multilingual, webdev
Hi all, So, a few months back, I kicked off a project to create a multilingual website. Let me tell you, managing content in multiple languages is a real headache. It’s doable if you’re only dealing with 3 or 4 languages, but once you hit 30+, it’s a whole different ball game trying to keep everything updated and consistent. To make life easier, I decided to bring in a CMS for my Astro-based site. I dug into frameworks like Wagtail and Strapi since I’m familiar with Python and Node.js, but man, those were tough nuts to crack. Plus, I wanted a centralized place for all my content instead of having to jump between different pages for each language. This way, I can easily compare content across languages without getting lost. And here's the kicker: ChatGPT is shaping up to be a solid translator, but no one’s integrated it into any frameworks yet. So, with my Django and Astrowind know-how (Astrowind is this cool UI built on Astro and Tailwind, and it’s open source), I whipped up a small Django library/framework to act as a headless CMS. I also tweaked the Astrowind source to pull in content from the CMS with multilingual support. Check out this demo if you wanna see it in action: https://django-astrowind.netlify.app/en Not much has changed from the original Astrowind (https://astrowind.vercel.app/), except now you can switch languages on the fly, and the content is managed through a CMS with hashed caching. If you’re interested in using it, I’ve put together a tutorial to help you set it up on your own machine: https://django-headless-cms.readthedocs.io/en/latest/quick-start.html Hope you dig it. And I hope my little project can be of some help to you guys.

In the early hours of today, I found myself deep in the trenches of an Ansible playbook problem while configuring `nginx` and `apache2` on some remote Ubuntu hosts. This journey was challenging but ultimately rewarding. Here’s a guide based on my experience to help you navigate similar issues. ## Initial Problem: Ansible and Missing Python Dependencies When running an Ansible playbook to configure `nginx` and `apache2`, one of the hosts refused to execute the playbook commands. Despite being able to SSH into the host, the commands wouldn't run. After some research, I discovered that the issue was due to missing Python dependencies, which Ansible relies on to function correctly. So, I installed all dependencies including Ansible again, just to make sure everything is up to date. ### Solution: 1. **Install Python Dependencies Ansible**: ```bash $ sudo apt update $ sudo apt install software-properties-common $ sudo add-apt-repository --yes --update ppa:ansible/ansible $ sudo apt install ansible ``` ## Subsequent Issue: Apache2 Fails to Start After resolving the initial problem, I encountered a new issue: while Apache2 installed successfully, it failed to start. The error message was: ``` Job for apache2.service failed because the control process exited with error code. See "systemctl status apache2.service" and "journalctl -xe" for details. ``` ### Debugging Steps: 1. **Check Service Status**: ```bash systemctl status apache2.service ``` 2. **Inspect Logs**: ```bash journalctl -xe ``` ### Common Issues and Fixes: 1. **Missing `ServerName` Directive**: - Apache2 requires a `ServerName` directive to avoid warnings. - Add `ServerName 127.0.0.1` to your Apache2 configuration file. ```bash echo "ServerName 127.0.0.1" | sudo tee /etc/apache2/conf-available/servername.conf sudo a2enconf servername sudo apache2ctl configtest ``` - If the configuration test passes, restart Apache2: ```bash sudo systemctl restart apache2 ``` 2. **Port Conflict with Nginx**: - Both `nginx` and `apache2` were attempting to start on port 80, causing a conflict. - Ensure they are configured to use different ports or that only one of them is running at a time. ### Resolving the Port Conflict: 1. **Change Apache2 Port**: - Edit the Apache2 ports configuration file: ```bash sudo nano /etc/apache2/ports.conf ``` - Change the `Listen` directive to a different port, e.g., `8080`: ```apache Listen 8080 ``` - Update your virtual host configuration to match the new port. 2. **Restart Services**: - Restart Apache2: ```bash sudo systemctl restart apache2 ``` - Restart Nginx: ```bash sudo systemctl restart nginx ``` ## Lessons Learned 1. **Persistence Pays Off**: - Troubleshooting can be frustrating and time-consuming, but persistence and determination are key. Even when the solution seems elusive, continue researching and testing. 2. **Attention to Detail**: - Small configuration errors can cause significant issues. Always double-check configuration files and ensure all directives are correct. 3. **Comprehensive Logging**: - Utilize system logs and status commands to gather detailed information about errors. These logs are invaluable for diagnosing problems. 4. **System Knowledge**: - Understanding how services interact on your system (e.g., port usage) can prevent conflicts and help in resolving issues faster. ## Final Thoughts Troubleshooting server configuration issues can be a daunting task, especially when using automation tools like Ansible. However, each challenge is an opportunity to learn and improve your skills. By documenting and sharing these experiences, we can help others navigate similar challenges more efficiently. Happy coding!

https://dev.to/jottyjohn/api-development-and-microservices-revolutionizing-modern-software-architecture-5a5b
In today's fast-paced digital landscape, the need for scalable, flexible, and efficient software solutions is more critical than ever. Two key technologies that have emerged to meet these demands are Application Programming Interfaces (APIs) and microservices. Together, they form the backbone of modern software architecture, enabling businesses to build robust, scalable, and adaptable systems. **Understanding APIs** Application Programming Interfaces (APIs) are sets of rules and protocols that allow different software applications to communicate with each other. They define the methods and data structures that developers can use to interact with external software components, operating systems, or services. **Types of APIs:** **REST (Representational State Transfer):** RESTful APIs use HTTP requests to perform CRUD (Create, Read, Update, Delete) operations. They are stateless and support multiple data formats, making them highly flexible and widely adopted. **SOAP (Simple Object Access Protocol):** SOAP APIs use XML to encode messages and rely on a set of strict standards. They are highly secure and suitable for enterprise-level applications. **GraphQL:** A query language for APIs, GraphQL allows clients to request only the data they need, reducing over-fetching and improving performance. **gRPC (Google Remote Procedure Call):** gRPC uses HTTP/2 for transport, Protocol Buffers for data serialization, and supports multiple programming languages, making it ideal for microservices. **Benefits of APIs:** - **Interoperability:** APIs enable different systems to work together seamlessly, regardless of the underlying technology stack. - **Modularity:** By breaking down applications into smaller, reusable components, APIs promote modularity and reduce development time. - **Scalability:** APIs allow for the easy scaling of applications by distributing workloads across different services. - **Innovation:** APIs enable developers to integrate with third-party services a nd leverage external functionalities, fostering innovation. **The Rise of Microservices** Microservices architecture is an approach to software development where an application is composed of small, independent services that communicate through APIs. Each service is designed to perform a specific function and can be developed, deployed, and scaled independently. **Key Characteristics of Microservices:** - **Decentralization:** Each microservice is a standalone entity, with its own database and runtime environment. - **Resilience:** Microservices are designed to handle failures gracefully. If one service fails, it does not affect the entire application. - **Scalability:** Services can be scaled independently based on demand, improving resource utilization and performance. - **Continuous Delivery:** Microservices support agile development practices, enabling continuous integration and continuous deployment (CI/CD). **Benefits of Microservices:** - **Flexibility:** Developers can choose the best technology stack for each service, leading to more efficient and effective solutions. - **Speed:** Smaller, focused teams can work on individual services, speeding up development and deployment cycles. - **Maintainability:** Isolating services reduces the complexity of the codebase, making it easier to maintain and update. - **Innovation:** Teams can experiment with new technologies and approaches without affecting the entire system. **The Symbiotic Relationship Between APIs and Microservices** APIs and microservices are inherently interconnected. APIs serve as the communication layer that allows microservices to interact with each other and with external systems. This symbiotic relationship enhances the capabilities of both technologies: - **Loose Coupling:** APIs enable microservices to remain loosely coupled, ensuring that changes in one service do not impact others. This decoupling fosters independent development and deployment. - **Service Discovery:** APIs facilitate service discovery mechanisms, allowing microservices to find and communicate with each other dynamically. - **Security:** API gateways provide a centralized point for implementing security measures such as authentication, authorization, and rate limiting, protecting the microservices ecosystem. - **Monitoring and Management:** APIs allow for the implementation of comprehensive monitoring and management tools, providing insights into the performance and health of microservices. **Best Practices for API Development and Microservices** **Design with the Consumer in Mind:** - Understand the needs of the API consumers and design APIs that are intuitive and easy to use. - Provide clear and comprehensive documentation to help developers integrate with your APIs efficiently. **Ensure Scalability and Performance:** - Optimize API performance by minimizing payload sizes, caching responses, and using efficient data formats. - Design microservices to handle varying loads by implementing auto-scaling and load balancing mechanisms. **Implement Robust Security Measures:** - Use secure communication protocols (e.g., HTTPS) to protect data in transit. - Implement authentication and authorization mechanisms to control access to APIs and microservices. **Promote Reusability and Modularity:** - Design APIs and microservices to be reusable across different applications and use cases. - Break down complex functionalities into smaller, manageable services that can be independently developed and maintained. **Monitor and Manage Effectively:** - Use monitoring tools to track the performance, health, and usage of APIs and microservices. - Implement logging and alerting mechanisms to detect and respond to issues promptly. **Conclusion** APIs and microservices have revolutionized the way software is developed and maintained, providing the scalability, flexibility, and efficiency required in today’s fast-paced digital world. By leveraging these technologies, businesses can build robust, adaptable systems that can quickly respond to changing market demands and drive innovation. Adopting best practices in API development and microservices architecture ensures that organizations can maximize the benefits while mitigating potential challenges, paving the way for a future-proof software ecosystem.

**Pre-Rendering** NextJS pre-renders HTML before JavaScript is loaded in the page so as to give it a view at least. React on the other hand loads only when JavaScript is loaded. **_Pros->_** 1. If there is an async call on a page load it will take time and it might show a loader or a single root element but in case of NextJS it will at least show you how the page looks like until JavaScript is loaded. 2. If there is SEO then, Pre-Rendering performs better in that aspect -> basically for blogs nor e-comm websites. 3. There is a wait time for the user.

The actual data represented by the NFT can be stored inline, on a server you administer, or on a third-party server. These are a few of the possible solutions you can use for third-party storage. ## Permanent Storage There are several service providers that offer persistent storage solutions for your NFT data. [IPFS](https://docs.ipfs.tech/concepts/what-is-ipfs/) is a modular suite of protocols for organizing and transferring data, designed from the ground up with the principles of content addressing and peer-to-peer networking. [Arweave](https://www.arweave.org/) is a permanent and decentralized web inside an open ledger. [Filecoin](https://filecoin.io/) is a data storage network backed by an application token. [Storj](https://storj.io) is based on blockchain technology and peer-to-peer protocols to provide secure, private, and encrypted cloud storage. [Chia Network](chia.net) develops a blockchain and smart transaction platform based on storage-based mining. ## Cached Storage Third-party NFT storage providers are increasingly focusing on storing these decentralized files and retrieving them fast for users. Many NFT marketplaces on XRPL today are storing cached versions of the IPFS originals to provide fast, reliable, and responsive websites. [Cloudflare Stream](https://blog.cloudflare.com/cloudflare-stream-now-supports-nfts/) helps creators publish their videos online without having to think about video quality, device compatibility, storage buckets or digging through FFmpeg documentation. [Infura](https://www.infura.io/platform/nft-api)’s NFT API makes the NFT metadata you need accessible and searchable. [Pinata](https://www.pinata.cloud/) is a web3 media management platform that offers tools to handle file storage, content distribution and premium content experiences. # Example - Pinata Pinata is a solution that allows you to store cached NFT information for rapid retrieval. ## What is Pinata? Pinata is a web3 media management platform that offers developers the easiest way to use IPFS (InterPlanetary File System). Pinata offers tools that handle the complexities of file storage, content distribution (via Dedicated Gateways), and creating premium content experiences (with Submarine). ## How to Upload to IPFS with Pinata There are two main ways you can upload files to IPFS with Pinata: the Pinata web app, and the Pinata API. ### Pinata Web App To get started, visit the Pinata website and sign up for a free account. A free starter account gives you up to 1GB storage and 100 files. To upload a file to Pinata: 1. Press **Upload**. 2. Select **File**. 3. Enter the file name. 4. Click **Upload**. When the file upload is complete, it is listed in your file manager with the name and CID for that file. ### Pinata API Use the Pinata API if you are building a platform or application and prefer to upload through an API. For example, the following is a node.js code snippet showing how to perform a file upload to Pinata: ```javascript var axios = require('axios'); var FormData = require('form-data'); var fs = require('fs'); var data = new FormData(); data.append('file', fs.createReadStream('/Users/Desktop/images/cat.JPG')); data.append('pinataOptions', '{"cidVersion": 1}'); data.append('pinataMetadata', '{"name": "MyFile", "keyvalues": {"company": "Pinata"}}'); var config = { method: 'post', url: 'https://api.pinata.cloud/pinning/pinFileToIPFS', headers: { 'Authorization': 'Bearer PINATA JWT', ...data.getHeaders() }, data : data }; const res = await axios(config); console.log(res.data); ipfs://QmRAuxeMnsjPsbwW8LkKtk6Nh6MoqTvyKwP3zwuwJnB2yP ``` See: - [Pinata Documentation](https://docs.pinata.cloud/?utm_source=dev-docs&utm_medium=dev-docs&utm_campaign=&utm_content=shardeum) - [Pinata SDK](https://www.npmjs.com/package/@pinata/sdk) ## How to view and retrieve content from IPFS with Pinata There are several different ways you can view and reference your content, including a Protocol URI, Public Gateway, and Dedicated Gateway. ### Protocol URI A standard IPFS URL looks like this: ``` ipfs://QmRAuxeMnsjPsbwW8LkKtk6Nh6MoqTvyKwP3zwuwJnB2yP ``` If you copy and paste that into your browser, you might not get anything back. That's because in order to use this one, you need to have a local IPFS node running to participate in the network. Even when you do, it will likely be slow, since IPFS is still a growing network. You might want to use a Protocol URI for a couple of reasons. If you're building on a blockchain that frequently uses IPFS, such as Ethereum or another L2 chain, many marketplaces and apps are compatible with this format. When they see it, they use tools to convert the URL into a gateway URL so it can display the content on a website. This can be a good thing or a bad thing. If the platform has a dedicated/private gateway, the speed is fast (much like other dedicated gateways). However, if the platform uses a public gateway, the speed can be slow. In the end, the platform has control over how well your content is received. Additionally, using the standard IPFS URL might help future proof your assets, as public gateways might be stopped in the future (however the CID is still in the URL in those cases, so if the platform knows what to do, they can still get the content, if pinned). ### Public Gateway A public gateway URL looks something like this: ``` https://gateway.pinata.cloud/ipfs/QmRAuxeMnsjPsbwW8LkKtk6Nh6MoqTvyKwP3zwuwJnB2yP ``` This delivers the content in the browser without the need of a local IPFS node. However, since this gateway is a public gateway, your speed might vary due to the heavy traffic and congestion. Some platforms will see this kind of the URL and switch it out with their own faster gateway choice, but not always. Generally you want to assume that if you take this path, the assets will be slow. ### Dedicated Gateway A dedicated gateway URL looks something like this: ``` https://pinnieblog.mypinata.cloud/ipfs/QmRAuxeMnsjPsbwW8LkKtk6Nh6MoqTvyKwP3zwuwJnB2yP ``` Dedicated Gateways are much much faster than any other method, and should ideally be used when trying to display content on your own platform. However, using them in an NFT project should be done with caution. If you use a Dedicated Gateway in your NFT project metadata and image links, your speed will be great, however any time another marketplace or rarity bot asks the blockchain for the IPFS data, your gateway will be hit. Since most Dedicated Gateways are paid services, this could greatly drive up your costs and usage. You’ll get the best performance, control, and flexibility with this method; however, you might have to pay more than the other methods.

**Dependency injection** is when an object provides the dependency of another object. This means that a class relies on methods from another class. It is a well-known design pattern, and Nest is built strongly based on this pattern. **Inversion of control** is a concept that aligns with dependency injection. It is basically delegating to the framework the construction of the project's dependencies. The purpose of injection is to invert control, providing the dependencies of the object instead of allowing it to create them itself. For this, it is necessary to: 1. Explicitly define the dependencies and where the injection occurs. In Nest, for example, this point is in the constructor. This is where the framework inverts control. `constructor(private catsService: CatsService) {} ` 2. Have an inversion of control container for dependency injection to occur. In Nest, it is possible to access this container through the module and retrieve the instance of the class we want. In short, what is done is transferring the task of instantiating the object to someone else (IoC) and directly using that instance as a dependency (Injection). **Advantages** of using this pattern: - Ease of testing the application (we can inject mocked services) - Improved code maintenance (reduction of code and decoupling) - Reusability (just inject the dependency to use it) **Disadvantages**: There are few, but generally: - Increased complexity in the project - Service construction logic can be in inaccessible places Thank you for reaching this point. If you need to contact me, here is my email: joaopauloj405@gmail.com References: https://www.digitalocean.com/community/tutorials/a-guide-on-dependency-injection-in-nestjs https://martinfowler.com/articles/injection.html https://www.youtube.com/watch?v=GX8YC21qQQk&t=1010s <link2>

This step-by-step tutorial will walk you through the process of creating a simple iOS app using Xcode and Swift. By the end of this guide, you will have a basic understanding of iOS app development and a functional app that you can build upon. **Step 1:** Setting Up Your Development Environment Before you start coding, you need to set up your development environment. Follow these steps to get started: **Install Xcode:** Xcode is Apple's integrated development environment (IDE) for macOS. You can download it for free from the Mac App Store. Make sure you have the latest version installed. **Create a New Project:** Open Xcode and select "Create a new Xcode project" from the welcome screen. Choose the "App" template under the iOS tab and click "Next". ## Configure Your Project: Enter the following details: **Product Name:** MyFirstApp **Team**: Your Apple developer account (if you have one) Organization Name: Your name or your company’s name **Organization Identifier: **A unique identifier (e.g., com.yourname) Language: Swift **User Interface:** Storyboard Click "Next", choose a location to save your project, and click "Create". **Step 2:** Designing the User Interface Now that your project is set up, it’s time to design the user interface (UI) of your app using Storyboard. **Open Main.storyboard:** In the project navigator, click on Main.storyboard. This will open the visual interface editor. **Add a Label:** Drag a Label from the Object Library (bottom right corner) onto the view controller. Center it horizontally and vertically. **Add a Button:** Drag a Button from the Object Library onto the view controller, placing it below the label. Center it horizontally. **Set Constraints:** To ensure your UI elements are positioned correctly on different screen sizes, set constraints: Select the Label, click the "Add New Constraints" button at the bottom of the editor, and set constraints to center it horizontally and vertically. Select the Button, set constraints to center it horizontally and position it a certain distance below the label. **Customize Text:** Double-click the Label and the Button to change their text to "Hello, World!" and "Press Me", respectively. **Step 3:** Connecting UI Elements to Code Next, we’ll connect the UI elements to our code so we can add functionality. **Open the Assistant Editor:** Click the overlapping circle button at the top right corner to open the Assistant Editor. This will display the storyboard and the corresponding view controller code side by side. **Create Outlets:** Control-drag from the Label to the ViewController.swift file to create an outlet. Name it greetingLabel. Do the same for the Button, but create an action instead, naming it buttonPressed. **Step 4:** Writing the Code Now that the UI elements are connected, we can add functionality to the button. Open ViewController.swift: Ensure you're in the ViewController.swift file. Implement the Button Action: Add the following code inside the buttonPressed function: @IBAction func buttonPressed(_ sender: UIButton) { greetingLabel.text = "Hello, iOS Developer!" } This code changes the text of the label when the button is pressed. **Step 5:** Running Your App **Select a Simulator:** At the top of the Xcode window, choose a simulator (e.g., iPhone 14). **Run the App:** Click the "Run" button (a play icon) or press Cmd + R to build and run your app on the selected simulator. **Interact with Your App:** Once the app launches in the simulator, you should see your label and button. Press the button to see the label text change. **Step 6:** Enhancing Your App Now that you have a basic app running, you can enhance it with more features: Change Background Color: Add a line of code in viewDidLoad to change the background color: override func viewDidLoad() { super.viewDidLoad() view.backgroundColor = UIColor.lightGray } **Add More UI Elements:** Experiment with adding more buttons, labels, and other UI elements. Use constraints to position them correctly. **Explore More Functionality:** Look into additional Swift and UIKit tutorials to learn how to handle user input, navigate between screens, and incorporate more advanced features. **Conclusion** Congratulations! You’ve built your first iOS app. This tutorial has introduced you to the basics of iOS app development, from setting up your development environment to designing your UI and writing code to add functionality. As you continue learning and experimenting, you'll discover the vast capabilities of iOS development and how you can create more complex and feature-rich apps. Happy coding!

codenewbie, beginners, javascript
When dealing with data, developers oftentimes have to create copies in order to not mutate the dataset. In JavaScript, data types are either passed by value or passed by reference so there are different ways to make proper copies depending on what you're working with. And if you don't do it right, your copy won't end up being a copycat but turn out to be a reference-cat (terrible joke). Never heard of a reference-cat? Good, because it doesn't exist and your incorrectly copied variables shouldn't either. ![simpsons copy gif](https://media.giphy.com/media/3orif28fKmGLblN1II/giphy.gif) ###Primitive Data Types **Primitive data types are passed by value and are immutable. So if we change it, a new instance is created.** There are six primitive data types, checked by JavaScript's `typeof` operator: * Boolean: `typeof instanceName === 'boolean’` * String: `typeof instanceName === 'string'` * Number: `typeof instanceName === 'number'` * undefined: `typeof instanceName === 'undefined'` * BigInt: `typeof instanceName === 'bigint'` * Symbol: `typeof instanceName === 'symbol'` ####Making a Copy of a Primitive Data Type To make a copy, all you have to do is create a new variable and assign its value to the variable you want to copy. ```javascript let str1 = 'noodles'; str1; // 'noodles' let str2 = str1; str2; // 'noodles' str1 === str2; // true str1 = 'pizza' // 'pizza' str1 === str2; // false str2; // 'noodles' ``` Above, I've created a new variable `str2` and assigned its value to `str1`. JavaScript has allocated a separate memory spot for `str2` so `str1`'s value is reassigned. `str2` is not affected because it is independent of `str1`. ###Non-Primitive Data Types **Non-primitive data types, however, are passed by reference and are mutable.** So if we change it, it can be difficult to keep track of and wacky things can happen if you're not careful. **Non-primitive data types include Object, Array, Set, and Map.** This means that arrays and objects assigned to a variable do not actually contain the other variable's values but rather point to the data type's reference in memory. ```javascript let obj1 = {1: 'noodles', 2: 'pizza'}; obj1; // {1: 'noodles', 2: 'pizza'} let obj2 = obj1; obj2; // {1: 'noodles', 2: 'pizza'} obj1 === obj2; // true obj1[3] = cake; obj1; // {1: 'noodles', 2: 'pizza', 3: 'cake'} obj2; // {1: 'noodles', 2: 'pizza', 3: 'cake'} ``` On the surface, `arr2` appears to get `arr1`'s values, but it's only pointing to `arr1`'s reference in memory. Any changes to made to `arr1` will be reflected in `arr2` and also vice versa as they are both pointing to the same reference. ####Making a Copy of a Non-Primitive Data Type There are a few different ways to make copies of objects in JavaScript. Depending on your needs, some of the methods will only shallow copy the object while others can support a deep copy. ####Spread Operator Using the spread operator will make a shallow copy of your object. It works great for all objects including arrays and objects. ```javascript const arr1 = ['noodles', 'pizza']; const copyArr = [...arr1]; copyArr; // ['noodles', 'pizza'] const obj1 = {1: 'noodles', 2: 'pizza'}; const copyObj = {...obj1}; copyObj; // {1: 'noodles', 2: 'pizza'} ``` ####Object.assign() Using `Object.assign()` will produce a shallow copy of your JavaScript object. Make sure to pass in an empty `{}` as the target argument so there is no mutation to be had. ```javascript //syntax Object.assign(target, ...sources); let obj1 = {1: 'noodles', 2: 'pizza'}; let copyObj = Object.assign({}, obj1}; // { '1': 'noodles', '2': 'pizza' } obj1 === copyObj; // false; obj1[3] = 'cake'; obj1; // {1: 'noodles', 2: 'pizza', 3: 'cake'} obj2; // {1: 'noodles', 2: 'pizza'} ``` ####Object.fromEntries(Object.entries()) Another shallow copy method for your JavaScript object is to use `Object.fromEntries()` in conjunction with `Object.entries()`. Introduced in ECMAScript 2019, `Object.fromEntries()` transforms a list of key-value pairs into an object. Using `Object.entries()` will turn the object you want to copy into key-value pairs, then using `Object.fromEntries()` will turn that into your very own object copy. ```javascript let obj1 = {1: 'noodles', 2: 'pizza'}; let copyObj = Object.fromEntries(Object.entries(obj1)); copyObj; // {1: 'noodles', 2: 'pizza'} ``` ####Array.from() Similarly to above, you can use `Array.from()` to make shallow copies of arrays. ```javascript const arr1 = ['noodles', 'pizza']; const copyArr = Array.from(arr1); copyArr; // ['noodles', 'pizza'] ``` ####JSON For a deeper copy of your objects, you can use `JSON` to first stringify your object to JSON and then parse the string back into an object. However, using JSON to make a deep copy only works when the source object is JSON safe. ```javascript const obj1 = {1: 'noodles', 2: 'pizza', 3: 'cake'}; const copyObj = JSON.parse(JSON.stringify(obj1)); copyObj; // {1: 'noodles', 2: 'pizza', 3: 'cake'} ``` ####Alternatives Using Libraries Though my copycat needs are typically met with one of the above methods, there are several external libraries out there that will deep copy your objects. These include [Lodash's cloneDeep()](https://www.npmjs.com/package/lodash.clonedeep) and [Underscore's clone()](https://underscorejs.org/). Clone away with any one of these methods knowing your copies are copycats and not those pesky reference-cats! *Resources* [Object.fromEntries()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/fromEntries) [3 Ways to Clone Objects in JavaScript](https://www.samanthaming.com/tidbits/70-3-ways-to-clone-objects/) [JavaScript Data Types and Data Structures](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Data_structures)

--- title: Building sync engines in WordPress published: true date: 2024-06-21 13:50:11 UTC tags: Evernote,Programming,WordPress,Readwise canonical_url: https://piszek.com/2024/06/21/wordpress-sync/ --- ![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/orgpki9t7w846xqnmn7o.png) Let’s say you want to synchronize some data in your WordPress with an external service. How do you do that? For my little [“Second Brain” WordPress plugin](https://github.com/artpi/personalOS/), I have implemented 2 sync services so far: - Readwise - Evernote Both of them synchronize data with a custom post type called “`notes`“. Here is what I learned ## WP-Cron All sync software has some kind of background service that looks for changes and syncs the detected ones. We do not have operating system access in WordPress to fire an actual process, but we have **wp-cron**. WP-Cron is a job management system designed for periodic or scheduled maintenance actions that need to be performed: like publishing scheduled posts, checking plugin updates etc. So here is what we are going to do: 1. We are going to create an `hourly` cron job for our sync. 2. Each job run will work through a batch – a limited number of elements (I gravitated towards 100 of updates) 3. Whenever this job finishes a run, it will check if more updates are waiting to sync. If so, - It will cancel the next run (in one hour) - Schedule itself in 1 minute - Unschedule any “regular” – hourly sync events so that at any time, there is only one sync event waiting We are doing all these because: - We don’t want any of these runs to be too compute and memory-intensive. WordPress is running on a variety of hosts with different limitations, and we don’t want our run to be killed - We don’t know how many updates in total we are expecting. I have 8000+ notes in my Evernote account, so the initial sync with Evernote will take quite some time. That’s why we redo the job every minute if there are pending updates - We don’t want to poll any external service too often because rate limits are a pain to manage ### New cron job I have a little abstraction layer of modules in my code, but essentially, each service has its own module. ``` class External_Service_Module extends POS_Module { public $id = 'external_service'; public $name = 'External Service'; public function get_sync_hook_name() { return 'pos_sync_' . $this->id; } public function register_sync( $interval = 'hourly' ) { $hook_name = $this->get_sync_hook_name(); add_action( $hook_name, array( $this, 'sync' ) ); if ( ! wp_next_scheduled( $hook_name ) ) { wp_schedule_event( time(), $interval, $hook_name ); } } public function sync() { $this->log( 'EMPTY SYNC' ); } } ``` So here is a simplified `sync` method for my Evernote module. [You can see the full code here.](https://github.com/artpi/PersonalOS/blob/f332bccfc26f1dfdb2136e4e94b695e61cd544ab/modules/evernote/class-evernote-module.php) ``` class Evernote_Module extends External_Service_Module { public $id = 'evernote'; public $name = 'Evernote'; public $description = 'Syncs with evernote service'; public $advanced_client = null; public function __construct( \POS_Module $notes_module ) { $this->register_sync( 'hourly' ); } /** * Sync with Evernote. This is triggered by the cron job. * * @see register_sync */ public function sync() { $this->log( 'Syncing Evernote triggering ' ); $usn = get_option( $this->get_setting_option_name( 'usn' ), 0 ); $sync_chunk = $this->advanced_client->getNoteStore()->getFilteredSyncChunk( $usn, 100, $sync_filter ); if ( ! $sync_chunk ) { $this->log( 'Evernote: Sync failed', E_USER_WARNING ); return; } if ( ! empty( $sync_chunk->chunkHighUSN ) && $sync_chunk->chunkHighUSN > $usn ) { // We want to unschedule any regular sync events until we have initial sync complete. wp_unschedule_hook( $this->get_sync_hook_name() ); // We will schedule ONE TIME sync event for the next page. update_option( $this->get_setting_option_name( 'usn' ), $sync_chunk->chunkHighUSN ); wp_schedule_single_event( time() + 60, $this->get_sync_hook_name() ); $this->log( "Scheduling next page chunk with cursor {$sync_chunk->chunkHighUSN}" ); } else { $this->log( 'Evernote: Full sync completed' ); } // ACTUALLY PROCESS ITEMS HERE } } ``` I have a very similar sync code for Readwise: ``` <?php class Readwise extends External_Service_Module { public $id = 'readwise'; public $name = 'Readwise'; public $description = 'Syncs with readwise service'; public function __construct( $notes_module ) { $this->register_sync( 'hourly' ); } public function sync() { $this->log( '[DEBUG] Syncing readwise triggering ' ); $query_args = array(); $page_cursor = get_option( $this->get_setting_option_name( 'page_cursor' ), null ); if ( $page_cursor ) { $query_args['pageCursor'] = $page_cursor; } else { $last_sync = get_option( $this->get_setting_option_name( 'last_sync' ) ); if ( $last_sync ) { $query_args['updatedAfter'] = $last_sync; } } $request = wp_remote_get( 'https://readwise.io/api/v2/export/?' . http_build_query( $query_args ), array( 'headers' => array( 'Authorization' => 'Token ' . $token, ), ) ); if ( is_wp_error( $request ) ) { $this->log( '[ERROR] Fetching readwise ' . $request->get_error_message(), E_USER_WARNING ); return false; // Bail early } $body = wp_remote_retrieve_body( $request ); $data = json_decode( $body ); $this->log( "[DEBUG] Readwise Syncing {$data->count} highlights" ); //phpcs:ignore WordPress.NamingConventions.ValidVariableName.UsedPropertyNotSnakeCase if ( ! empty( $data->nextPageCursor ) ) { // We want to unschedule any regular sync events until we have initial sync complete. wp_unschedule_hook( $this->get_sync_hook_name() ); // We will schedule ONE TIME sync event for the next page. //phpcs:ignore WordPress.NamingConventions.ValidVariableName.UsedPropertyNotSnakeCase update_option( $this->get_setting_option_name( 'page_cursor' ), $data->nextPageCursor ); wp_schedule_single_event( time() + 60, $this->get_sync_hook_name() ); $this->log( "Scheduling next page sync with cursor {$data->nextPageCursor}" ); } else { $this->log( '[DEBUG] Full sync completed' ); update_option( $this->get_setting_option_name( 'last_sync' ), gmdate( 'c' ) ); delete_option( $this->get_setting_option_name( 'page_cursor' ) ); } foreach ( $data->results as $book ) { $this->sync_book( $book ); } } } ``` ## Two-way sync In the case of Evernote, we can have a two-way sync. When you update something in Evernote, the above job will trickle the updates to WordPress. If you update something in WordPress, it should reflect in Evernote. The **main trap is an update loop**. We want to avoid a loop where you update something in WordPress, Evernote picks up the change and updates there, so WordPress gets the notification, updates in Evernote… ![](https://piszek.com/wp-content/uploads/2024/06/recursion-winnie.gif) So here is what we are going to do: 1. We are going to hook into `save_post_` hook. This means we don’t have to **really** do sync. We assume WordPress is online, which means that we can push updates **synchronously** when they happen, not after some time, hopefully reducing conflicts. 2. We are going to update the edited post with the returned Evernote content **immediately** on save. That way: - Even if Evernote changes the data on their end, we are sure that after post saving the data is similar on both ends - We can calculate the bodyHash and other indicators to know if data got out of sync 3. Since we are going to update WordPress end **again** after pushing data to Evernote, we have to remember to unhook `save_post_` hook to prevent recursion. 4. This is not relevant to WordPress, but because Evernote has a limited syntax, we have to strip out and convert some data. Here is the simplified code. [You can read the whole thing here.](https://github.com/artpi/PersonalOS/blob/f332bccfc26f1dfdb2136e4e94b695e61cd544ab/modules/evernote/class-evernote-module.php) ``` /** * This is hooked into the save_post action of the notes module. * Every time a post is updated, this will check if it is in the synced notebooks and sync it to evernote. * It will then receive the returned content and update the post, so some content may be lost if it is not handled by evernote * * @param int $post_id * @param \WP_Post $post * @param bool $update */ public function sync_note_to_evernote( int $post_id, \WP_Post $post, bool $update ) { $guid = get_post_meta( $post->ID, 'evernote_guid', true ); if ( $guid ) { $note = $this->advanced_client->getNoteStore()->getNote( $guid, false, false, false, false ); if ( $note ) { $note->title = $post->post_title; $note->content = self::html2enml( $post->post_content ); $result = $this->advanced_client->getNoteStore()->updateNote( $note ); } return; } // edam note $note = new \EDAM\Types\Note(); $note->title = $post->post_title; $note->content = self::html2enml( $post->post_content ); $result = $this->advanced_client->getNoteStore()->createNote( $note ); if ( $result ) { $this->update_note_from_evernote( $result, $post ); } } /** * This is called when a note is updated from evernote. * It will update the post with the new data. * It is triggered by both directions of the sync: * - When a note is updated in evernote, it will be updated in WordPress * - When a note is updated in WordPress, it will be updated in evernote and then the return will be passed here. * * @param \EDAM\Types\Note $note * @param \WP_Post $post * @param bool $sync_resources - If true, it will also upload note resources. We want this in most cases, EXCEPT when we are sending the data from WordPress and know the response will not have new resources for us. */ public function update_note_from_evernote( \EDAM\Types\Note $note, \WP_Post $post, $sync_resources = false ): int { remove_action( 'save_post_' . $this->notes_module->id, array( $this, 'sync_note_to_evernote' ), 10 ); // updates updates add_action( 'save_post_' . $this->notes_module->id, array( $this, 'sync_note_to_evernote' ), 10, 3 ); return $post->ID; } ``` ## Gutenberg blocks as sync items Evernote’s core primitive is a note. But in the case of Readwise sync, I was stuck between 2 primitives: - Individual highlight - A book/article/podcast I decided to store the books/articles as post type (of `note`), but keep highlights’ individual existence as blocks of the **Readwise** type. Each block is tracked individually. Each instance of the block is appended in PHP – [I published how to do it in a separate tiny tutorial.](https://piszek.com/2024/03/19/get_comment_delimited_block_content/) ![](https://piszek.com/wp-content/uploads/2024/06/Zrzut-ekranu-2024-06-21-o-13.29.01.png) You can see how the block is implemented in this pull request: [https://github.com/artpi/PersonalOS/pull/1](https://github.com/artpi/PersonalOS/pull/1) Subscribe to my newsletter to get updates my Personal OS plugin and my other musings: The post [Building sync engines in WordPress](https://piszek.com/2024/06/21/wordpress-sync/) appeared first on [Artur Piszek](https://piszek.com).

Introduction Hello there! So, you're a beginner starting to prepare for the [Microsoft AZ-900 Exam](https://docs.microsoft.com/en-us/certifications/exams/az-900)? Feeling overwhelmed by all the new concepts you have to learn? No need for that! Passing the AZ-900 Exam is actually simpler than you might think. Heck, I passed it as a 16-year-old with a score of 955/1000. Hopefully, that's enough to motivate you. In this blog, I will guide you in simple and concise words on how you can study and pass the exam with flying colours! ## Study Pathway We will look at the most simple and beginner-friendly pathway to study for the exam. This includes all the resources you will need (I'll also sprinkle in some of my personal favourites). I will give you some tips and tricks as well. Lastly, I will let you in on a little secret: the shortcut to success! (I mean dumps or past-exam-questions). ## Prior Knowledge ## How much knowledge do you need prior? To be honest, a novice in computers will be perfectly alright! AZ-900 is meant for beginners; it does not expect you to have much experience in the field. This certification is great to have under your belt. If your goal is to get your feet wet with tech and cloud, you are walking down the right path. Study Time ## How much time will it take? After cutting all the time wasted procrastinating, I spent roughly about 2-3 hours per day for 3 weeks. It really depends on factors like how detailed you are going to study, whether you will be taking your own notes, and how much computer and cloud knowledge you have prior to this. To sum it all up, it shouldn't take you too long to clear the exam, even if you are a complete beginner. ## Resources ## What about the resources? For the [AZ-900 Exam](https://dumps2go.com/dumps/az-900/), resources are abundant. The best part, it's all free! Here are some of the best study materials available, in my opinion: Official Microsoft AZ-900 Learning Pathway: I think it's your best bet. It covers all the syllabus according to the exam (the great news is that it's now updated according to the new syllabus!). Adam Marczak YouTube Channel: My personal favourite; he makes amazing and comprehensible video lectures with (cute!) visual animations that make it easy to grasp complex concepts. John Savill YouTube Channel: Although his video lectures steer towards concepts that are somewhat unrelated to the exam and it gets a bit confusing (especially if you are a beginner), I still think his content is very useful. He even has updated lectures according to the new syllabus. ## Shortcut to Success? (Dumps) By now, you probably have seen the word "dumps" splattered around. Dumps is another word for past-exam-questions. Let's get this straight: attempting dumps is very important! Why? Firstly, they can help you realize the areas in which you are lacking and further solidify your knowledge in that area. Moreover, you will get an idea of what type of questions are asked in the exam. And most importantly, a majority of the questions are repeated. Beware! If you only rely on dumps and don’t actually study and research the concepts, your understanding won't be concrete, and in actual work environments, you will show terrible lack. Try not to fall too deep into the rabbit hole. ## Where to look for dumps? Looking for dumps is not as easy as you might think at first. Firstly, there is a plethora of shady websites begging you to pay for dumps; never do that! Don’t pay a penny. Moreover, irresponsible authors have stated wrong answers to questions, so make sure to do your research rather than blindly trusting them! I have had a good experience with the following websites: [Dumps2go.com](https://dumps2go.com/) ## Summarizing No need to pay a dime. All resources are widely available for free (AZ-900 Exam Questions). Definitely make sure you are aware of the new changes to the syllabus. Do practice dumps, but don’t fall too deep into the rabbit hole. Make sure you have sound knowledge of the concepts! **Best of luck, I believe in you! **

nocode, lowcode
The goal is clear: Idea to software, [10x faster than traditional full-code development](https://www.qikbuild.com/can-you-really-build-software-10x-faster/). With [no-code software development](https://www.qikbuild.com/) there are many use-cases, when you can build your product(web or mobile app) a lot faster than with traditional “full-code” development, the difference can be 3x, 5x or 10x compared with the traditional development. ## What is no-code development? No-code is a software development approach that usually doesn’t require any programming skills and is often called visual programming, mainly because the software is built using drag and drop editors for front-end and the same for backend logic. # What is no-code software development? No-code software development allows you to build the same type of apps as you would do with the traditional development, but a lot faster. The main advantage of no-code development is that you can re-use existing components and functionalities instead of building everything from scratch. There’s often a misconception that building applications in no-code is just editing some pre-built templates. (for example like WordPress templates) That’s usually not the case. Of course most of these no-code and low-code development platforms allow you use templates. You can use them or you can start with a “clean plate”. Even if you don’t use existing template for your idea, you can create a an application in no-code 10x faster compared to traditional development, Let’s be honest, most of the applications consist are just a combination of some basic operations, non-rocket-science backend logic, some nice UI and interactive dashboards, few(or a lot of) integrations and some data processing/aggregation. This applies for most SaaS, marketplaces, directories, CRMs, internal tools, AI apps (usually AI is one of the integrations) etc. So If you’ll be worried that no-code approach will be limiting you in product development, I can assure you that 99% of the times that won’t be the case. Current no-code development platform allow you to build almost anything, regardless if it’s SaaS, directory, marketplace, airbnb/booking clone, UBER clone or anything else. # Why should you decide for no-code development? Usually, IT project means heavy budgets, >6 months never-ending system maintenance. That is case for most of traditional development project. If you ever been part of at least one bigger software project, you’ll probably agree. With no-code development, you can solve all three of these issues: Why should you decide for no-code development? These are top reasons why any company (startup, SME, enterprise) should consider no-code software development. - Build features faster: When launching a new product, it’s crucial to be able to launch as soon as possible, gather feedback and pivot if necessary. No-code development allows you to have your MVP ready in less than 1 month and make quick changes based on user/market feedback - Reduce development costs: Development costs for startups are high because IT resources are expensive and it usually takes a lot of time to build the product. In QikBuild we believe that success of a startup should not be dependent on technology costs but rather on viability of business idea. So if the speed of development is fraction of time compared to traditional development, so is the cost. - Maintenance: No-code tools usually doesn’t require any maintenance(database upgrades, external integrations maintenance etc.) required for your app going smoothly. - Better IT-business collaboration: Given that many small changes can be implemented by teams without any technical knowledge (changing static texts, alignments, colors etc.), IT department can focus on the “hard stuff”, instead of spending time on things that are below their expertise # What no-code tools do we recommend for 10x faster development? ## Web applications **WeWeb** WeWeb is the tool you want to choose when building front-end for web applications, whether it’s SaaS, marketplace, CRM or any internal tool. WeWeb has a comprehensive UI editor with hundreds of pre-built components, it allows to create front-end business logic, provide pre-built connectors to back-ends such as Xano, Supabase and some others. What we really love about WeWeb, is that you can import your own Vue.js components from your Github repository and you can also export and self-host the entire application You can read [our review](https://www.qikbuild.com/weweb-xano-vs-bubble-nocode-review/) using WeWeb combined with Xano against Bubble for no-code development of web applications. **Bubble.io** We’ve worked with Bubble for quite few years and we have to say that it really is one of the most powerful all-in-one no-code development platforms. It combines UI builder for front-end with managed database, so that you don’t have to build your app with two different tools. However after spending few years with Bubble, we believe that it’s a great choice for more simple applications, but when you need to build something that you know for sure will grow into complex app, we would recommend an alternative. (as mentioned above) **Retool** If you are building a tool for internal use, Retool is really worth a considerations. What we really like about it, is that it’s not trying to be all-in-one for every possible use-case, but the are focusing specifically on building internal tools. However there’s one thing we actually don’t like – and that’s pricing. Here you have to also pay for the end user. (e.g. your employees using the app you’ve built with Retool) Most of the no-code development platforms have different pricing – performance/resource based. But if this is not an issue, we think you’ll like Retool a lot. ## Mobile applications **FlutterFlow** FlutterFlow is currently the most powerful no-code development platform for mobile applications. That’s all you need to know when you’re considering to build a mobile app with no-code stack. That doesn’t necessarily means that it might be ideal one to build your project. FlutterFlow is really powerful, but it also means it has steeper learning curve than some of the other mobile development platforms. If you are thinking about building a professionally looking, customer facing mobile app, we definitely recommend FlutterFlow, but if you want to build a personal/hobby app or some simple internal application, we recommend to keep scrolling. The other two platforms might be a better fit. **Adalo** We like Adalo mainly for its simplicity. Almost anyone can build a simple mobile application in Adalo, without the need of having separated back-end. What you need to consider is that with it’s simplicity, there’s a high chance you’ll find many limitations either from UI or business logic perspective. But again, let’s be honest, most of the internal or hobby apps doesn’t require so much flexibility so there’s good chance that Adalo might be a great fit for simple projects ## Back-end & automations **Xano** Managed database, no-code API builder, re-usable functions, custom code lambda functions, authentication and many more is what Xano offers. For quite some time, Xano has been our go-to platform for projects of almost all sizes. Whether you are building simple internal app, complex SaaS applications or enterprise-level software, Xano can cover all you need to build secure, scalable and reliable back-end. **Make** Make is an amazing tool for all types of automations. It can be used to automate day-to-day tasks, help with team-level automations or setup company wide processes. All in a single tool. With it’s database of thousands of pre-built connectors, you can integrate multiple apps together within just few clicks, instead of spending months integrating them together with traditional development. # Are there any limitations of no-code development? There are and there aren’t. But the limitations are not where most people think they are. - Features & UI: >90% of features withing your product can be built in no-code with pre-build functionalities. And if it happens you’ll hit the limit – most of the platforms (we use mainly WeWeb & Xano) allows you to use custom code on both frontend and backend - Scaling: We often hear that with no-code apps, you can scale only for MVP with few users. This is one of the most often misconception about no-code development. With platforms like Xano, you can scale to thousands or millions of users for your app. - Vendor lock-in and technology: These no-code development platforms use specific technologies to build your app. In most cases, you can’t just switch the underlying technology for another (let’s say switch Vue to React in WeWeb or switch PostgreSQL DB to MySQL DBin Xano)

## Introduction *Gen AI for data privacy* I set out several months ago to deeply understand and engage with the modern AI tooling that is in the process of revolutionizing (or at least sensationalizing!) the world of Web Development as we know it. I had a single purpose, to build a [theoretically scalable system](https://privacytrek.com/) that could leverage this plethora of new technologies. And one that wouldn’t bankrupt me in the process. I picked a use case that was an area of interest to me, and one that I felt was ripe for the use of Generative AI. In this case, it is the world of data privacy. I built a tool that can scan any public-facing web URL, navigate and register all the network requests that have been made from this resource with a recordable user journey. Then we analyze these requests and process the information in a standardized way using Generative AI. Gen AI is a valid use case because the world of data privacy is complicated in the sense that it is difficult to understand the meaning and consequences of compliance. I believe that Generative AI is mainly functional as a data synthesizer, a reducer. Much of the current frustration comes from erroneous use of LLMs that involve inputting a nugget of data and expecting Gen AI to mass-produce gold. It inevitably churns out rubbish. But if you input a high concentration of quality data, and ask Gen AI to condense this into something useful, that’s when you get valuable output. So what do I want Gen AI to do? Simple really, as someone who has been doing Web Development for nearly 20 years, I still find myself unable to answer seemingly trivial questions: 1. Do I need permission to track user data, which types? What is “user” data anyway? An IP address? 2. I’m not saving that PII, so it’s legal right? Right? 3. When can I set cookies? 4. But I use a Cookie to track my Cookie consent. That’s allowed I guess? But what is a “functional” Cookie anyway? 5. What kind of user tracking is permitted with and without consent? 6. How do I need to ask for consent? 7. Can I save consent? How do I even persist negative consent? 8. What is the difference between consent for tracking and cookies, do I need both? Is that one button or two? 9. What are the consequences of not respecting consent? 10. How does this vary by geography? 11. Is Google Analytics legal for use in Europe? Quite honestly, a lot of the confusion in the above arise because data privacy consent is a grey area with room for interpretation. This isn’t helped by a difference in legislation between different geographies. But the key is that GPT-4o/Llama 3 excel at interpreting vast amounts of data and explaining them with simple language. Perfect, thank you. So I set out to gather as much hard evidence as I could about what is actually happening on a simple navigation on a public-facing document (i.e., website!). We map this evidence with our understanding of the legislation, and we arrive at [a system that is capable of testing the data processing flow of any public website.](https://privacytrek.com/) Woohoo. But you aren’t here for the cookies, are you? You’re here for the AI… One little system, one bucket load of AI. --- <div class="bg-gray-200 p-4 rounded text-black text-lg my-4"> ### AI Technologies and Their Applications - **OpenAI - GPT-4o / DALL-E 3** We use this to analyze the COMPANIES that are the ultimate processors of the ingested data. - **Groq - Llama3-70b-8192** We use this to analyze the REQUESTS where the data is transmitted from the public document. - **Grok - [https://developers.x.ai/](https://developers.x.ai/)** We use this to analyze sentiment and trends to inform our content generation strategy. - **Brave API - [https://brave.com/search/api/](https://brave.com/search/api/)** We use this to research public information on actors identified within our system. - **Algolia search - [https://www.algolia.com/](https://www.algolia.com/)** We use this to intelligently map unstructured data into a lovely SQL database. </div> ## Did you say 5? *Five different AI products?* How was my experience with this mesh of AI? Very, very hard… It nearly broke me. So how did we end up with a platform that has 5 different AI integrations anyway? Experimentation, repetition, and a fair bit of lunacy. [It’s a pattern.](https://tyingshoelaces.com/blog/odyssey/chapterone) But when we untangle the system we have created, each component part makes sense. The first trade-off is [Groq](https://groq.com/) vs ChatGPT. ChatGPT is, of course, the flagship product of OpenAI, the first worm out of the proverbial can. And their first mover advantage shows. Their API and models have been more refined, and this is clear from the quality difference of the output. So I use ChatGPT for the long-form content and the quality of the results is indisputable. BUT. It’s expensive. I woke up in sweats several times a week worrying what would happen if somebody, anybody, actually used this platform I’d built. A great experiment, but one I’m not willing to bankrupt myself for. Not likely. Groq changed everything. Their API costs 100x less. It’s fair to say that had I not discovered Groq, I would probably have never released this blog, simply out of fear of the cost. The quality of gpt-4o over llama 3 is noticeable. But the price of Llama 3 on Groq is quite literally 1% of the price. I use [OpenAI](https://openai.com) if we need to leverage content of the absolute highest quality. I use Groq when I need to process lots of information. I have built a kill switch to turn everything to Groq at a second's notice. This switch is the difference between being able to launch or not. <div class="highlight text-lg leading-snug mt-8 mb-4 border-l-4 border-white pl-4"> “<br>gpt-4o<br><br>$5.00 / $15.00 per 1 million tokens.<br><br> </div> <div class="highlight text-lg leading-snug mt-8 mb-4 border-l-4 border-white pl-4"> “<br>Llama3-7b<br><br>$0.05/$0.08 (per 1M Tokens, input/output)<br><br> </div> So our AI count is at two out of the door… Where does [Brave AI Search](https://brave.com/search/api/) come in? You could easily interchange this with Perplexity AI or similar, I was very impressed with the API offering. Brave found its way into the stack as I was building my own SERP crawler and researcher. Mine was rubbish and consuming a lot of time, Brave’s was excellent. Mine worked 50% of the time; [Brave’s 95%](https://brave.com/search/api/). To be able to generate high-quality content for people we need to solve several puzzles. We need thorough research and we also need to know what is interesting for the user. Brave’s search API is excellent for doing research for AI content. It provides links, references, and shows high traffic suggestions for users to follow the content rabbit-trail. Without the research from Brave, the results from ChatGPT and Groq would be spam. It is a wonderful AI to feed research and data into our AI. That’s a 2024 phrase if ever I’ve heard one. 3 down… Onto the most controversial selection. Grok by [Twitter (x)](https://developers.x.ai/) is an LLM with a difference. It has social media retrieval built-in (I imagine it has some kind of proprietary RAG). How does this help? This helps us understand content and topics that are trending and new. So before we research and generate content, we need to understand what are the hot topics. I’m not yet convinced by the viability of Grok, but the potential to be able to plug into real-time sentiment and use this with a search and content generation strategy is an exciting one for me. Put this one down as experimental. I’ll keep you posted. So we end up with Algolia. Why do we need an AI-powered search on top of our AI-powered research and generative AI? This comes down to how I’ve structured my platform. We’ll go deeper into the how and the why later in this article, but to build a world-class platform we need to fill in some of the basics. In my old-school paradigm, you can’t have world-class content without a world-class CMS. World class CMS requires clean structured data. SQL. We use [Algolia](https://www.algolia.com/) to weave and map together the content from our different systems. It’s hard to strongly define and limit output from text generation models, (company recognized could be Shopify, Shopify’s App, Shop App). Getting JSON output is more or less stable these days. But converting JSON output to SQL with references between content types, this is tricky due to the unstructured nature of text generation. Algolia bridges this gap by condensing ‘similar’ content into unique SQL data that can be consumed by a website. It’s not perfect. But it works (95% of the time). So here we are, 5 AIs in the hype boom forged, with one simple platform to rule them. ## It was hard. *It nearly broke me.* We go from theoretical to engineering concerns. Chaining AI API calls to create a tolerable product. So why is using AI so hard? Fundamentally there is one simple reason. The Internet is now fast. We expect things to be fast. Even AWS API Gateway HTTP requests timeout after a maximum of 30 seconds. But generative AI? Just crafting an image, with researched content and output can require up to 5 chained calls to various APIs. 1. Identify the content (Sentiment analysis w/Grok) 2. Research the content (AI Search w/Brave) 3. Generate the content (Gen AI w/Llama3/ GPT-4o) 4. Generate the image (Gen AI w/DALL-E 3) 5. Save the content and image into SQL (Algolia) ![AI generated image of HotJar company from privacytrek.com](https://tyingshoelaces.com/hotjar.webp) [Example content: HotJar data privacy analysis on privacytrek.com](https://privacytrek.com/data-privacy-analysis/hotjar) It’s very hard to build something fast when the underlying APIs are so slow. You won’t get quality output reliably generated in under a minute, especially as you need to knit together disparate APIs to build anything resembling quality content. The perfectionist in me refuses to wait so long to deliver results on a website. We’ve come too far. What’s the solution? Streaming? Websockets? Background processes? It’s complicated… I tried every single one of the above. I hated every single one for different reasons; we could write a blog about each… I spent almost a week building and tweaking a Rabbit MQ broker so that my platform could subscribe to content from the backend responsible for negotiating with this mesh of AI APIs. I was so proud of myself, it was wonderful. It was also absolute rubbish. I deleted it. You know that saying, ‘Every person has a book in them. Most should keep it there.’ The same applies for Software Engineers and their AI ideas. It’s so easy to go off on a tangent and build around the problems that are inherent in artificial intelligence tools. I’ve done it many times until I reluctantly accepted that you can’t make an elephant run and we needed a different approach. You should too. Like horse and carriage congestion in the early 20th Century, eventually it won’t be a problem. But until it isn’t, it is. Users expect fast web experiences, a sprinkle of AI will only sate patience for so long before web experiences become onerous and frustrating. So, to use AI at scale, we need to fetch our data before the user has even arrived. The number one rule for leveraging AI is to derive the value from our business logic long before the user has arrived. The key to the kingdom is to use every word, every image. Every scrap of expensive generated content should be treated like proverbial gold. This means vigilant control of both inputs and outputs. And so I save every API request, I thoroughly research every API call I make. I test and I tweak, I iterate and I learn until I can bend the tool to my will. ## AI Costs $$$ *Treat AI API calls with the respect they deserve.* AI is prohibitively expensive. Imagine paying 5c for every API call you made to your CMS. I challenge you to do some math in your observability platform. Just look at the logs of any modern software system; requests to modern systems are typically measured in the hundreds of thousands, or millions… To make AI valuable at scale, we can’t treat its output as transient or ephemeral. The first thing I learned about working with AI APIs, save every response, output, or image. It can be used later. And one of the ironic properties of AI output is that the more you refine and reuse it (condensing), the more valuable and realistic it becomes. Just make sure you conserve the building blocks or you will literally be paying the price. It’s funny how paying and being on the hook for your own system really takes you back to the basics as an engineer. Nothing strikes fear into a developer more than being on the hook for a faulty API call that could accidentally cost thousands of dollars. Nothing will make me optimize my API fallback strategy like the fear that an accidental loop could bankrupt me. Frankly, we should treat normal APIs with the same respect, but caching, cheap processing and just laziness have made this approach redundant. The founding principle of working with these APIs is to treat every output from an LLM with respect. Spend time considering the inputs and the outputs. Prompt engineering, RAG, Vector DBs - these are the buzzwords. The principles are far more simple. Every question or input to a Gen AI system is costing you real dollars. Have you optimized that input to ensure that what is coming out is actually valuable? Or are you simply pounding away at a broken slot machine, throwing your money down the drain? I spent a long time crafting every user and system prompt, optimizing the inputs and the outputs to ensure that what comes out of the LLM is of value. I failed more than I succeeded. It took me a long time to get beautifully crafted artisan image representations of my companies. I spent days trying to use ChatGPT to create an icon library (bad idea). The more you work with these APIs, the easier it is to see the cracks. It’s so easy to get rubbish output; if you haven’t carefully automated and scaled the input it is the most likely outcome. But when the robot gets it right, it becomes something very special indeed. ## Ask ChatGPT *Just ask ChatGPT?* In my experience, the inverse is true; these LLMs aren’t generalists at all, but specialists. I don’t know why this is surprising. Machine learning algorithms have always been thus. We have object detection models to detect objects from images. We have structured data extraction algorithms to extract data from text. We wouldn’t expect our object detection algorithm to extract structured data from text, right? But that is exactly what we do expect from our LLMs. One superhuman AGI robot to rule them all. Absolute popsicle… Nothing screams amateur to me more loudly than the companies building a wrapper to ChatGPT and assuming that “AI” will solve their problem. The LLMs have no AGI at all, not even intelligence. They are capable of processing extremely large datasets. Just the thought that they are a silver bullet to every problem shows me that not much thought has been given at all. What are they specialists at? Condensing large amounts of information into valuable, smaller intelligible versions of the same. Ironically, the exact opposite of the majority of use cases. Welcome to the trough of disillusionment. LLMs are a tool in the armory that can solve problems in new and inventive ways. They have opened doors that we didn’t even know existed. So what next for this great experiment? We are at the beginning. I guess I’ve got a proof of concept; my goal is to convert this into a functional modern platform. There are challenges to overcome. The Field of Dreams conundrum. I’ve built it. Will they come? Experience tells me that probably not. I need to turn this platform into a self-aware, SEO-optimized monster. I’m going to use AI and the tools I've woven together to craft and scale human-consumable content and bring [Data Privacy analysis to the world…](https://privacytrek.com) I’m not sure how far I’ll get, but it’s turning out to be a wonderful adventure… Do come along for the ride. ## Links *All the links and resources* - [Privacy Trek Website](https://privacytrek.com) - [Originally published](https://tyingshoelaces.com/blog/artificial-intelligence-production-system)

dom, aripovdev, javascript
JavaScriptda DOM (Document Object Model) veb-sahifalar bilan o'zaro aloqada bo'lish uchun muhim vositadir. DOM HTML yoki XML hujjatlarini obyektlar daraxti ko'rinishida tasvirlaydi. Har bir element hujjatning br qismi sifatida ifodalanadi, bu esa JavaScript yordamida hujjat tuzilishini o'zgartirish, qo'shish yoki olib tashlash imkonini beradi. ![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/vu30a8aqo6xs11r8r3y2.png) DOMGA kirish: ``` // ID orqali elementni olish let elementById = document.getElementById("myElement"); // Klass orqali elementlarni olish let elementsByClassName = document.getElementsByClassName("myClass"); // Teg orqali elementlarni olish let elementsByTagName = document.getElementsByTagName("div"); // CSS selektor orqali elementni olish let elementByQuerySelector = document.querySelector(".myClass"); // CSS selektor orqali barcha mos elementlarni olish let elementsByQuerySelectorAll = document.querySelectorAll(".myClass"); ``` ``` // Yangi element yaratish let newElement = document.createElement("div"); newElement.textContent = "Yangi element"; // Yaratilgan elementni mavjud elementga qo'shish document.body.appendChild(newElement); // Mavjud elementni olib tashlash let elementToRemove = document.getElementById("oldElement"); document.body.removeChild(elementToRemove); // Mavjud elementni almashtirish let newElementToReplace = document.createElement("span"); newElementToReplace.textContent = "Yangi element"; let oldElement = document.getElementById("oldElement"); document.body.replaceChild(newElementToReplace, oldElement); ``` DOM bilan ishlash JavaScriptda veb-sahifalarni dinamik tarzda o'zgartirishga, foydalanuvchi bilan o'zaro aloqada bo'lishga imkon beradi va bu veb-dasturlashning muhim qismidir. - **HTMLCollection** - **NodeList** HTMLCollection va NodeList JavaScriptda DOM elementlarini guruhlash va ularga kirish uchun ishlatiladigan ikkita asosiy turdir. Ular ko'p jihatdan o'xshash bo'lsa-da, ularning muhim farqlari mavjud. **HTMLCollection** HTMLCollection HTML elementlarining yig'indisini ifodalaydi.HTMLCollection dinamik bo'lib, DOMdagi o'zgarishlarni avtomatik ravishda aks ettiradi. Ya'ni, agar siz DOMga yangi element qo'shsangiz yoki olib tashlasangiz, HTMLCollection avtomatik ravishda yangilanadi. HTMLCollection indeks yoki elementning id yoki name atributi orqali elementlarga kirishga imkon beradi.HTMLCollection o'ziga xos metodlarga ega emas, ammo massivlarga o'xshash length xususiyati va indekslash yordamida elementlarga kirish imkoniyatini beradi. **HTMLCollection**(methods) - getElementById(id): ID bo'yicha elementni qaytaradi. - getElementsByClassName(className): Berilgan klassga ega bo'lgan barcha elementlarni qaytaradi. - getElementsByTagName(tagName): Berilgan tegga ega bo'lgan barcha elementlarni qaytaradi. - querySelector(cssSelector): CSS selektoriga mos keladigan birinchi elementni qaytaradi. - querySelectorAll(cssSelector): CSS selektoriga mos keladigan barcha elementlarni qaytaradi. **NodeList** NodeList DOMdagi barcha nodelarning yig'indisini ifodalaydi. Bu nodelar elementlar, matn nodelari va boshqalar bo'lishi mumkin. NodeList statik yoki jonli bo'lishi mumkin. querySelectorAll() metodi statik NodeListni qaytaradi, bu NodeList yaratilgandan keyin DOMdagi o'zgarishlarni aks ettirmaydi. Boshqa tomondan, childNodes dinamik NodeListni qaytaradi.NodeList indeks orqali elementlarga kirishga imkon beradi.NodeListda forEach() metodi mavjud, bu metod yordamida elementlar bo'yicha iteratsiya qilish osonroq. **NodeList**(methods) - document.querySelectorAll() - Node.childNodes - document.getElementsByTagNameNS() ![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/ppsku2k3at7ok42duuq5.png) Bu farqlarni bilish, DOM bilan ishlashda to'g'ri tanlov qilishga yordam beradi. HTMLCollection asosan faqat HTML elementlar bilan ishlash uchun mo'ljallangan, NodeList esa ko'proq universal va har qanday DOM tugunlari bilan ishlash uchun qulay.

tailwindcss, mui, css, ui
CSS framework is crucial for frontend development as it can greatly enhance your workflow and enhance the aesthetic appeal of your user interface. Tailwind css and material ui are two of the most used alternatives for different projects. Let's look at each one closer, compare and contrast, and see which one is best for your next project. ## Tailwind CSS [Tailwind css](https://tailwindcss.com/) is a framework that uses low level utility classes to construct designs quickly, making it a first class implementation. **Utility-first Approach:** Tailwind css uses small, single-purpose utility classes to simplify development. To illustrate, you can use classes to design a button with your own personal styling like `bg-blue-500`, `text-white`, and `px-4 py-2`. ``` <button class="bg-blue-500 text-white px-4 py-2 rounded">Click me</button> ``` **Flexibility and Customisation:** Tailwind css doesn't require any predefined styles, giving developers the freedom to create their own designs. Ui components can be customised to suit a project's needs. ``` <div class="bg-gray-200 p-4 rounded-lg shadow-md"> <h2 class="text-2xl font-bold text-gray-800">Tailwind CSS Example</h2> <p class="text-gray-600 mt-2">Customizable and flexible design</p> </div> ``` **Ease of Learning:** Easy to learn and use, simple syntax and direct style implementation in html make it easy for developers to use. ## Pros Of Tailwind CSS - **Speed and Efficiency:** Boosts development velocity with prebuilt resources. - **Highly Customisable:** Can be extensively modified without the requirement of custom css. - **No Global Scope Issues:** Prevents international style disputes from happening. - **Responsive Design:** Easy to use utility classes for designing responsive designs. - **Community Support:** A lively group with a plethora of resources and plugins. ## Cons of Tailwind CSS: - **Learning Curve:** Utility first approaches may not be a skill that developers are comfortable with. - **Cluttered HTML:** A lot of utility classes can obstruct html files. - **Design Consistency:** A certain level of discipline to ensure consistent design throughout the application. - **Design Limitations:** It is not likely to achieve highly personalized or exceptional designs without additional work. - **Tooling Dependencies:** You'll probably need to use other build tools like purgecss to optimize production builds. ## Material-UI [Material ui](https://mui.com/) is a react ui framework that meets google's material design requirements and provides a range of prebuilt, fully customizable react components. Developers love material ui because it's easy to use. **Component-Based Development:** Material ui is a collection of pre-existing react components built on material design principles, like the button, appbar, card, etc. These components can be easily modified to meet the needs of any project. ``` import { Button, Typography } from '@mui/material'; const ExampleComponent = () => ( <div> <Typography variant="h2" color="primary">Material-UI Example</Typography> <Button variant="contained" color="primary" disableElevation>Click me</Button> </div> ); ``` **Theming Capabilities:** Framework comes with a powerful theming system that lets developers customize the appearance and feel of their applications. Material ui's theming utilities can be used to create a dark theme, for example. ``` import { createTheme, ThemeProvider } from '@mui/material/styles'; const darkTheme = createTheme({ palette: { mode: 'dark', }, }); const ThemedApp = () => ( <ThemeProvider theme={darkTheme}> <Button variant="contained" color="primary">Dark Theme Button</Button> </ThemeProvider> ); ``` **Comprehensive Documentation and Community Support:** A large community of people and documentation that enables the launch and upkeep of projects. ## Pros Of Material-UI - **Consistent Design:** Ui design that is consistent and well designed, material design guidelines. - **Accessibility and Responsiveness:** Responsiveness and accessibility features make it easy to use on all devices. - **Developer-Friendly:** Development is simplified with prebuilt components and inbuilt documentation. - **Theming Capabilities:** A system for grading the appearance and ambiance of components. - **Component-Based:** Modular and reusable architecture is gaining traction. ## Cons Of Material-UI - **Bundle Size:** Bundle size enlarged because of the pre-installed features and styles. - **Customisation Effort:** Might need more effort to customize beyond the scope of material design. - **Design Limitations:** If the project doesn't follow material design guidelines, it might feel limiting. - **Learning Curve:** It is necessary to familiarize oneself with Material-UI's API and theming system in order to proceed. - **Overhead:** Css in js adds more dependencies and makes the project more difficult. | Feature | Tailwind CSS | Material-UI (MUI) | |------------------------|-------------------------------------------|-----------------------------------------| | **Design Philosophy** | Utility-first approach | Component-based approach | | **Ease of Use** | Requires learning utility classes | Provides ready-to-use components | | **Customization** | Highly customizable with configuration | Customizable via theme and props | | **Styling** | Utility classes applied directly in HTML | CSS-in-JS, inline styles, and styled-components | | **Component Library** | No built-in components | Rich library of pre-built components | | **Performance** | Lightweight, minimal CSS output | May include additional JavaScript overhead | | **Learning Curve** | Steeper for those new to utility-first CSS| Easier for those familiar with React components | | **Documentation** | Extensive and well-organized | Comprehensive with examples and demos | | **Community Support** | Large and active | Large and active | | **Theming** | Manual setup required for themes | Built-in theming support | | **Responsive Design** | Built-in responsive utilities | Responsive components and grid system | | **CSS Approach** | Uses a single CSS file | Uses CSS-in-JS | | **Framework Agnostic** | Yes, can be used with any framework | Primarily for React | | **Ecosystem** | Smaller, fewer third-party plugins | Large, with many third-party components | | **Development Speed** | Fast once utility classes are mastered | Fast due to ready-made components | | **Bundle Size** | Smaller, as you only include what you use | Larger due to bundled components | | **Flexibility** | High, can style any component | Moderate, dependent on provided components | ## Which Should You Choose? Tailwind css or material ui are two options that should be considered for your project, considering the project's specific requirements and development style. - Tailwind css is a versatile design approach that is well suited for projects that require rapid development and extensive customization. - Material ui is ideal for projects that prioritize consistent design and adhere to material design principles, providing a complete set of pre-built components and theming options. ## Conclusion Tailwind css and material ui are both good frontend development tools. Your project's requirements, team's experience, design preferences will determine which one to choose. Tailwind css is a practical approach with lots of flexibility, material ui is a good ui design and has great theming capabilities.

Developers have a wide range of options when it comes to displaying work, exchanging expertise, and interacting with the community in the ever changing digital landscape. Developer blogs and developer-focused social media sites like Stack Overflow, Github, and X (formerly Twitter) are some of the most well-known channels. Selecting the appropriate platform can have a big impact on your personal brand, reach, and engagement. This article explores the benefits and drawbacks of each choice to assist you in selecting the strategy that will work best for you. ### Developer Blogs Blogs are online platforms where individuals or groups regularly publish written content, often called posts or articles, on various topics. These posts can range from personal stories and opinions to professional advice and technical tutorials. Blogging allows for in-depth exploration of subjects, providing a space for detailed explanations, tutorials, and thought leadership. It’s an effective way to establish an online presence, share knowledge, and engage with a specific audience. For beginners, starting a blog can be a way to develop writing skills and share their passions, while experienced individuals can use blogs to showcase their expertise and build a professional reputation. Overall, blogging is a versatile and powerful tool for communication and self-expression on the internet. #### Strengths and Weaknesses of Developer Blogs **Strengths** **1. Long-form Content:** Blogs allow for in-depth articles, tutorials, and case studies. You can thoroughly explore complex topics, providing values to you readers. **2. SEO Benefits:** A well-optimized blog article can generate organic traffic from search engines, improving your visibility and attracting a consistent stream of readers over time. **3. Personal Branding:** A blog is a personal space where you can showcase your expertise, style and personality, establishing yourself as an authority in your field. **4. Monetization Opportunities:** Blogs can be monetized through ads, sponsorship, affiliate marketing, and selling digital products like e-books or courses. Opportunities such as guest blogging, collaborations, and even job offers can come your way. **Weaknesses** **1. Time-Consuming:** Creating high-quality blog posts require significant time and effort, from research and writing to editing and promoting. **2. Audience Building:** It can take a while to build a substantial audience, especially if you are starting from scratch. 3. Regular Updates, website maintainance, and security are ongoing responsibilities that come with running a blog. ### Developer-Focused Social Media Platforms Exploring developer-focused social media networks can significantly benefit a developer's career by providing unique opportunities for learning, networking, and collaboration.

The reputation system encourages quality contributions and peer recognition. **Strengths** **1. Problem-Solving:** A great platform for asking questions, finding soluions, and contributing answers. **2. Reputation System:** The reputation system can highlight your expertise and credibility. 3. Community Support: Access to a vast community of developers for support and collaboration. **Weaknesses** **1. Strict Moderation:** The community moderation can be strict, potentially discouraging new users. **2. Content Longevity:** Answers may get buried over time, reducing long-term visibilty. ### Which Platform Caters Better to Different Content Types? #### Long-form articles **Developer Blog:** The clear winner for detailed tutorials, comprehensive guides, case studies, and personal insights. #### Quick Updates and Insights **X (formerly Twitter):** Ideal for sharing short updates, quick tips, news, and engaging in real time conversations. #### Code and Technical Documentation **GitHub** Best for sharing repositories, collaborating on code, and documenting technical projects. #### Problem-Solving and Q&A **Stack Overflow:** Perfect for asking technical questions, finding solutions, and establishing credibility through contributions. ### Audience Reach and Engagements Strategies #### Developer Blog * **SEO Optimization:** Use keywords, meta description, and backlinks to improve search engine rankings. * **Consistency:** Regularly publish high-quality content to attract and retain readers. * **Promotion:** Share your blog post on social media, forums, and developer communities to drive traffic. #### Social Media Platforms * **Engagement:** Actively participate in discussions, respond to comments, and network with other developers. * **Hashtags and Trends:** Use relevant hashtags and participate in trending topics to increase visibility. * **Content Diversity:** Share a mix of content types, including code snippets, quick tips, project updates, and personal insights. ### Conclusion: Blog, Social Media, or Both? Choosing between a developer blog and social media depends on your goals and the type of content you want to share. If you enjoy writing in-depth articles and want to build a personal brand with long-term value, a developer blog is the way to go. If you prefer quick interactions, networking, and showcasing code, social media platforms like X, GitHub, and Stack Overflow are excellent choices. For many developers, a combination of both might be the most effective approach. Use your blog for detailed content and personal branding, while leveraging social media for quick updates, netwrking, and driving traffic to your blog. This multi-platform strategy can maximize your reach, engagement, and impact in the developer community. Success lies in grasping the unique strengths and weaknesses of each platform and smartly combining them. Whether you prefer blogs or social media (or both!), the key is to regularly share valuable content and actively engage with your audience. It's like putting together puzzle pieces: each platform adds its own flavor to your journey, making it an exciting adventure of discovery and connection.

Welcome to Day 3 of our Data Structures and Algorithms (DSA) series! Today, we'll delve into one of the most fundamental data structures: Arrays. By the end of this post, you'll have a solid understanding of arrays, their properties, and common operations performed on them. Let's get started! 🚀 please subscribe to my [YouTube channel](https://www.youtube.com/@DevDivewithDipak?sub_confirmation=1 ) to support my channel and get more web development tutorials. ## What is an Array? 🤔 An **array** is a collection of items stored at contiguous memory locations. The idea is to store multiple items of the same type together. This makes it easier to calculate the position of each element by simply adding an offset to a base value, i.e., the memory location of the first element of the array (generally denoted by the name of the array). ### Key Characteristics of Arrays - **Fixed Size**: Arrays have a fixed size, which means the number of elements is determined when the array is created. - **Indexed Access**: Elements in an array are accessed using an index. The first element is at index 0. - **Homogeneous Elements**: All elements in an array are of the same type. ## How to Declare and Initialize Arrays in JavaScript 📜 ### Declaration In JavaScript, you can declare an array using square brackets `[]` or the `Array` constructor. ```javascript // Using square brackets let arr1 = []; // Using Array constructor let arr2 = new Array(); ``` ### Initialization You can initialize arrays with values at the time of declaration. ```javascript let numbers = [1, 2, 3, 4, 5]; let fruits = ["apple", "banana", "cherry"]; ``` ## Common Operations on Arrays 🛠️ ### 1. Traversing an Array To traverse an array means to access each element of the array exactly once. ```javascript let arr = [10, 20, 30, 40, 50]; for (let i = 0; i < arr.length; i++) { console.log(arr[i]); } ``` ### 2. Inserting Elements In JavaScript, you can use methods like `push`, `unshift`, and `splice` to insert elements into an array. ```javascript let arr = [10, 20, 30]; // Inserting at the end arr.push(40); // [10, 20, 30, 40] // Inserting at the beginning arr.unshift(0); // [0, 10, 20, 30, 40] // Inserting at a specific position arr.splice(2, 0, 15); // [0, 10, 15, 20, 30, 40] ``` ### 3. Deleting Elements To delete elements from an array, you can use methods like `pop`, `shift`, and `splice`. ```javascript let arr = [10, 20, 30, 40, 50]; // Deleting from the end arr.pop(); // [10, 20, 30, 40] // Deleting from the beginning arr.shift(); // [20, 30, 40] // Deleting from a specific position arr.splice(1, 1); // [20, 40] ``` ### 4. Searching for Elements You can search for elements in an array using methods like `indexOf` and `includes`. ```javascript let arr = [10, 20, 30, 40, 50]; // Searching for an element let index = arr.indexOf(30); // 2 let exists = arr.includes(40); // true ``` ### 5. Updating Elements To update elements in an array, you simply access the element by its index and assign a new value. ```javascript let arr = [10, 20, 30, 40, 50]; arr[2] = 35; // [10, 20, 35, 40, 50] ``` ## Time Complexity of Array Operations ⏱️ Understanding the time complexity of array operations helps in writing efficient code. - **Accessing Elements**: O(1) - **Inserting/Deleting at the End**: O(1) - **Inserting/Deleting at the Beginning**: O(n) - **Inserting/Deleting at an Arbitrary Position**: O(n) - **Searching for an Element**: O(n) ## Conclusion 🎯 Today, we explored arrays, one of the most fundamental data structures. We learned how to declare, initialize, and perform common operations on arrays. Understanding arrays is crucial as they form the basis for more complex data structures and algorithms. Stay tuned for Day 4, where we will dive into Linked Lists, their properties, and operations. Feel free to leave your comments or questions below.

When you use any software, application, or website, the first thing you notice is its interface consisting of different visual elements, such as images, icons, text, etc. This is usually referred to as the front end, also known as the client side. The front end encompasses everything visible to a user while navigating through a website and constitutes a crucial part of any application or website for end-user interaction. However, before launching any application or website, it is crucial to ensure that all visual elements are correctly placed and function as intended. This is where the importance of front-end testing comes into play. In this article, we aim to enlighten you on front end testing, its importance, its types, best practices. ## What is Front End Testing? Front-end testing is a software testing type that assesses an application’s or website’s interface for its look and feel. It evaluates the graphical interface’s visual elements (icons, images, text, links, forms, menus, etc.) for their functionality. It checks whether all visual elements behave as per end users’ requirements and expectations. For example, front-end testing checks if: - The text field accepts only characters. - The email field accepts characters, symbols, and numbers. - The field to enter a contact number accepts only numbers. - The form gets submitted only after all the mandatory fields are filled. - The navigation is easy and clean. - A specific button is functioning correctly. - The page loading speed is fast enough and much more. In addition, front end testing checks the app’s or website’s compatibility across different browsers and devices. Every application or website architecture has three tiers – presentation, application, and data. Front end testing aims to evaluate the functionality of the presentation layer and ensure that it is free from bugs and errors. However, it is important to note that a testing team performs front-end testing after every update to an application or website. This ensures the recent updates do not affect the UI’s functionality and look. ## How Does Front End Testing Differ From Back End Testing? As we have discussed, front end testing evaluates an application’s user interface for its looks and functionality. Simply put, it verifies the app’s presentation layer is free from bugs and errors and functions as intended. Before moving to back end testing, let us understand what the back end is. The back end of any application or website is a part that makes it functional and is not visible to end users. It comprises different components, including data storage, business logic, databases, and server-side scripting. It is also referred to as the server side. Back end testing evaluates the functionality and correctness of back end components. It primarily focuses on testing an app’s or website’s business logic, performance, and security. ## The Need for Front End Testing Here are some major reasons that state the importance of front end testing: ### Identify Performance Issues User experience is paramount when it comes to any software application or website. If users find any issues navigating through the app, they are more likely to stick to alternatives. Did you know that 85% of customers do not return to a website with a poor user experience? During development, developers primarily focus on the application and data layers rather than the presentation layer, which forms the foundation for any app or website. Hence, it becomes crucial for the QA team to test the presentation layer by keeping end users’ perspectives in mind. This helps uncover potential client-side performance issues that may degrade the user experience. ### Verify the Cross-Browser and Cross-Device Compatibility Validating the app’s or website’s functionality across a range of browsers (different versions) and devices is another reason for front-end testing. People use different kinds of devices (laptops, tablets, etc.) and browsers (Firefox, Safari, Google Chrome, etc.) Therefore, it’s crucial to make sure that the app functions as intended across a range of hardware and web browsers. For cross-browser testing, the testing team makes use of real devices (hardware) and browsers. ### Assess the Integration of Third Party Services Third-party integrations have elevated user experiences. They help to extend a specific app’s or website’s functionality. However, all third-party integrations are not developed by trusted organizations. Many individual developers also release their integrations publicly, which may sometimes be faulty. If users leverage faulty integrations with an app or website, it ultimately degrades the user experience. Hence, assessing the app for all third-party integrations is a must. ## Types of Front End Testing Here are some different types of front-end testing: ### Unit Testing Unit testing evaluates an application’s or website’s components (smallest units) individually to verify that they function as intended. It is the lowest level of testing, where testers or developers take each component or feature and test it to ensure that it behaves as you want it to in production. This helps uncover defects in the early stages of development, leading to a reliable and stable codebase. ### Integration Testing Integration testing checks whether the integration of unit-tested modules does not result in any errors and whether they communicate properly. It uncovers any bugs or errors resulting from the integration of unit-tested modules. Test stubs and test drivers are used to carry out integration testing. ### Acceptance Testing As the name suggests, acceptance testing evaluates the application or website for its acceptability. It is categorized into two types – User acceptance testing (UAT) and Business acceptance testing. The former evaluates the app to verify that it meets the specified end-user requirements. The latter assesses the app to check whether it complies with business objectives and technical requirements. ### Visual Regression Testing It is apparent that every development team makes frequent changes to the code. Regression testing ensures that any recent changes made to an application or website do not affect its existing functionality. Hence, it is an inevitable software testing type for every test suite. The same logic applies to [visual regression testing](https://testgrid.io/blog/visual-regression-testing-guide/). However, the difference here is that regression testing is performed to check the effect of code changes on visual elements. It involves capturing the screenshots of the UI before and after making code changes and comparing them to determine any differences using image comparison tools. ### Accessibility Testing Accessibility testing is the subset of usability testing. It ensures that your app or website is accessible to every kind of user on the internet, including people with disabilities (hearing and visual impairment) or other special requirements. It verifies that any individual can access the app’s features under any condition. ### Performance Testing An app’s or website’s performance plays a vital role in improving user experience. Some major app performance metrics include responsiveness, scalability, end-user experience, stability, and reliability. Performance testing ensures the app or website is highly responsive, stable, and scalable under specific conditions. The app or website is put through varied loads to determine its performance and uncover potential bottlenecks that may degrade the user experience. ### Cross-Browser Testing As the name indicates, cross-browser testing verifies that a website works well across distinct browser and device combinations. It involves executing the same set of test cases across different combinations of devices and browsers and their versions. By doing this, you can ensure that your website is compatible with each browser and its versions. ## Challenges of Front End Testing Let us now throw light on some of the most common challenges of front end testing: ### 1. Constantly Evolving UI The app’s core library and third-party components are upgraded every few months, and upgrading any library requires you to change all other necessary components. As a result, every upgrade requires all components to be retested. This is one of the major challenges for the front end testing team. ### 2. Determining Crucial UI Elements The user interface of any application or website has multiple visual elements. These elements include graphics, formatting, layout, visible text, and functional aspects, such as buttons, submit forms, clickable links, etc. Front end testing checks how fast these elements load, how responsive they are, and how quick they are at executing user requests. As there are a lot of elements and aspects to evaluate, it becomes challenging for the front end testing team to prioritize testing the most crucial elements. To start with, check whether the pages load quickly with all the intended elements in the right place. Later, ensure that all functional elements respond to user requests. Finally, verify that formatting and all graphics load correctly. ### 3. Simulating the Real-World Environment Another major challenge in front end testing is simulating the real-world environment to test applications or websites. Usually, any app or website is tested in a controlled environment. Hence, it becomes difficult to get an idea of how it works in the real world, i.e., outside of the controlled testing environment. ### 4. Choosing the Right Automation Tool As front end testing involves evaluating a lot of elements, and that too after every update, it is not feasible for manual testers to accomplish it. This is where the role of automation tools comes into play. Well, there is a plethora of automation testing tools available for front end testing. Hence, it becomes overwhelming to choose the right one. Also, it is important to note that you must choose the tools based on the type of testing you want to perform. For instance, if you want to carry out performance testing, a few tools to consider are Jmeter, LoadRunner, NeoLoad, and LoadUI. ### 5. Detecting Cross-Browser or Cross-Device Issues People across the world use different versions of browsers and devices to access the Internet. As a result, testers must cover a massive range to test the application or website to evaluate its readiness for real-world use. However, this is challenging as new versions of browsers and devices are released constantly. Hence, testers need to keep up with the new versions to perform testing. ## Front End Testing Best Practices Here are some of the best practices to follow when testing your app’s graphical interface: ### 1. Use the Testing Pyramid The testing pyramid serves as a framework that provides a sequence for the types of tests to be performed on an application or website. In short, it serves as a blueprint for novice testers. Unit testing is present at the bottom of the testing pyramid, with integration testing at its top. The topmost tier is end-to-end testing. After these tests are done, add visual regression testing, acceptance testing, performance testing, etc., to the testing pipeline. ### 2. Prioritize Front End Elements The front end consists of hundreds and sometimes thousands of UI and functional elements. UI elements include formatting, text, CSS, and graphics, while functional elements include forms, links, buttons, etc. It is important to decide the testing priority of these elements. For instance, testing text, images, load time, and other essential features are priority elements, followed by graphics and layout. ### 3. Use Real Browsers and Devices Using real browsers and devices while testing provides an idea of how the app or website will actually function in the real world. It is better to avoid using simulators and emulators. ## Conclusion Front end testing is an indispensable aspect in the development of any software application or website. It verifies that the app’s or website’s presentation layer is free from bugs and has all the intended elements appropriately placed and functioning correctly. It ensures that the app or website provides the best user experience possible. Besides, front-end testing requires meticulous planning and execution. In addition, the success of testing depends on the right tool. Source : This blog is originally published at [TestGrid](https://testgrid.io/blog/front-end-testing/)
