1,898,425 | JavaScript Ninja Tricks: Mastering the Art of Shortcuts | Hey there, fellow JavaScript enthusiasts! Whether you're a seasoned developer or just starting out,... | 0 | 2024-06-24T05:49:39 | https://dev.to/ayushh/javascript-ninja-tricks-mastering-the-art-of-shortcuts-7d2 | javascript, webdev, beginners, programming | Hey there, fellow `JavaScript enthusiasts`!
Whether you're a seasoned developer or just starting out, JavaScript is full of hidden gems and clever shortcuts that can make your code more elegant and efficient. In this blog, we'll dive into some of the latest and most useful tricks to level up your JavaScript skills. Let's get started with a few quick tips:
`1. Array Destructuring in Function Parameters`
> Destructuring in JavaScript isn't just for arrays and objects anymore. You can use it directly in function parameters to extract values from arrays passed as arguments:
```
// Instead of
function foo(arr) {
const [first, second, third] = arr;
console.log(first, second, third);
}
// You can write
function foo([first, second, third]) {
console.log(first, second, third);
}
foo([1, 2, 3]); // Output: 1 2 3
```
`2. Optional Chaining (?.)
`
> Dealing with nested objects and null checks can be cumbersome. Optional chaining allows you to safely access deeply nested properties without causing an error if a property doesn't exist:
```
const user = {
id: 1,
name: 'Alice',
address: {
city: 'Wonderland',
postalCode: '12345'
}
};
// Instead of
const city = user.address ? user.address.city : 'Unknown';
// You can use
const city = user.address?.city ?? 'Unknown';
console.log(city); // Output: Wonderland
```
`3. Nullish Coalescing Operator (??)
`
> The nullish coalescing operator provides a convenient way to fallback to a default value only when a variable is null or undefined, but not for other falsy values like '' or 0:
```
const username = null;
const defaultUsername = 'Guest';
// Instead of
const finalUsername = username !== null && username !== undefined ? username : defaultUsername;
// You can write
const finalUsername = username ?? defaultUsername;
console.log(finalUsername); // Output: Guest
```
`4. Template Literals for String Interpolation
`
> Template literals (${}) are great for string interpolation, allowing you to embed expressions directly inside strings:
```
const name = 'John';
const age = 30;
// Instead of
console.log('My name is ' + name + ' and I am ' + age + ' years old.');
// You can use
console.log(`My name is ${name} and I am ${age} years old.`);
```
`5. Rest Parameter Syntax (...)
`
> The rest parameter syntax (...) allows you to represent an indefinite number of arguments as an array. It's particularly useful for functions that can accept a variable number of arguments:
```
function sum(...numbers) {
return numbers.reduce((acc, num) => acc + num, 0);
}
console.log(sum(1, 2, 3, 4)); // Output: 10
```

GitHub provides a lot of minutes in its free plan. Additionally, you can paste images, close issues, link to the code, use command lines, and easily manage files.
On the other hand, in BitBucket, you can use different tools like Jira, Crucible, and Bamboo. There are a lot of built-in tools. For instance, wiki, issue tracker, etc. Moreover, it’s way more flexible than GitHub. It can import from Git, CodePlex, Google Code, etc. Its semantic search is also better. It can crawl your syntax and find definitions. Its Jira and Trello integration is also the best!
**Cons**
But the problem with GitHub is that it has a steep learning curve. This means that there are some concepts that will be really difficult for people to grasp. At times, it may be a hassle to learn all the concepts. What’s more, is that the privacy of some accounts is limited. This means that everyone can see your code. This can be dangerous if you want to keep your code confidential. Moreover, GitHub is dependent on an internet connection. This means that if the internet is down, then you might face some access issues.
There are also some times when developers complain about performance issues when they are dealing with large repositories. There aren’t simple PR management tools in BitBucket. The repositories that are private are only free for just 1 to 5 members. Want to add new members? You need to pay! Users also face search-related problems while searching for a file. At times, the process is elongated because the users have to find it locally. That’s why for some, BitBucket is not a user-friendly interface.
**Who Should Use GitHub and BitBucket?**
BitBucket should be your preferred choice if you need only a small number of users in a single project and multiple private projects. It will be cheaper for you this way. For larger teams where multiple users are collaborating, GitHub is better.

1,898,420 | Boosting Delhi's Digital Economy: The Impact of Internet Exchanges | Delhi, a bustling metropolis and the heart of India, is fast becoming a crucial node in the... | 0 | 2024-06-24T05:42:28 | https://dev.to/decix/boosting-delhis-digital-economy-the-impact-of-internet-exchanges-cj3 | routeserverpeeringindia, internetexchangepointsindelhi |
Delhi, a bustling metropolis and the heart of India, is fast becoming a crucial node in the country’s digital ecosystem. The city’s burgeoning digital economy owes much of its progress to implementing Internet Exchange Points (IXPs) strategically. These IXPs are pivotal in enhancing internet connectivity, optimizing traffic management, and fostering economic growth. The transformation led by these digital infrastructures is proving to be a game-changer for Delhi’s internet landscape.
**Understanding Internet Exchanges and Their Importance**
An Internet Exchange Point (IXP) is a physical infrastructure through which Internet Service Providers (ISPs) and Content Delivery Networsks (CDNs) exchange Internet traffic between their networks. The primary goal of an IXP is to reduce the distance that data has to travel, reduce latency, and improve the speed and efficiency of data transmission. In Delhi, robust IXPs have significantly enhanced the region's internet performance.
**Enhancing Connectivity through Peering**
Peering is a process by which two or more ISPs directly connect and exchange traffic without involving a third party. This direct exchange is facilitated by **[route server peering India](https://www.de-cix.in/peering-services/)**, which helps manage the traffic more efficiently. Peering has become increasingly popular among ISPs in Delhi, improving internet speeds and reliability. By bypassing intermediaries, ISPs can offer better services to their users, thereby boosting user satisfaction and driving the digital economy forward.
**Economic Implications of Improved Internet Infrastructure**
The economic impact of improved internet infrastructure through IXPs and peering is profound. According to industry reports, efficient internet traffic management can lead to significant cost savings for ISPs, which can be passed on to consumers through lower prices. Additionally, businesses benefit from faster and more reliable internet services, crucial for operations in today’s digital age. This, in turn, fosters a more conducive environment for innovation and entrepreneurship in Delhi.
The increased efficiency and reduced latency also encourage international businesses to invest in Delhi’s digital economy, knowing that the city’s internet infrastructure can support high-demand operations. The cascading effect of such investments further stimulates job creation and economic growth in the region.
**Challenges and the Way Forward**
Despite the evident benefits, some challenges need addressing to maximize the potential of IXPs in Delhi. One significant challenge is ensuring equitable access to peering for all ISPs, regardless of size. Smaller ISPs often need help to compete with larger counterparts due to the high costs of setting up peering arrangements. There is a need for regulatory frameworks that promote fair competition and support the growth of smaller ISPs.
Moreover, continuous investment in upgrading and expanding IXPs is crucial. As internet usage grows, so does the demand for more robust and scalable infrastructure. Collaborative efforts between government bodies, private sector stakeholders, and international partners are essential to sustain this growth trajectory. The strategic deployment of **[Internet Exchange Points](https://www.de-cix.in/de-cix-delhi/)** in Delhi reshapes the city’s digital economy. Through efficient and robust route server peering, Delhi is witnessing improved internet connectivity, which is vital for economic growth and digital transformation. Addressing the challenges of equitable access and continuous investment will further bolster Delhi’s position as a leading digital hub in India. The future looks promising as Delhi leverages its enhanced internet infrastructure to drive innovation, attract investment, and foster economic development. | decix |

1,898,402 | Simple chatbot to improve Happiness | This is a submission for Twilio Challenge v24.06.12 What I Built The idea about this... | 0 | 2024-06-24T05:34:19 | https://dev.to/agkosd/simple-chatbot-to-improve-happiness-2e2n | devchallenge, twiliochallenge, ai, twilio | *This is a submission for [Twilio Challenge v24.06.12](https://dev.to/challenges/twilio)*
## What I Built
<!-- Share an overview about your project. -->
The idea about this project is very simple. Its an attempt to boost positivity as people are more and more stressed in their daily lives. Simple things such as viewing images of nature(or actually going out for a walk in sunlight), pets, reading positive quotes etc. can provide quick mood improvements(ref).
This whatsapp chatbot would basically send you images of cute dogs and daily stoic quotes and refer you with additional details on how to get more help if possible.
Github: https://github.com/agkosd/twilio
## Demo
<!-- Share a link to your app and include some screenshots here. -->
### Scenario 1
{% embed https://youtube.com/shorts/90yLvzwxUYc?feature=share %}
This video shows a scenario where in you are feeling perfectly fine and would keep on recieving daily stoic quotes. For the purpose of recording this video the cron job was set to run every second.
### Scenario 2
{% embed https://youtu.be/M2CmgGa_7aA %}
This shows the entire flow of the application from the start to the time you recieve a message.
## Twilio and AI
<!-- Tell us how you leveraged Twilio’s capabilities with AI -->
I have used whatsapp and sms messaging channels alongwith google gemini.
The way it works is we start by sending a hello to a twilio chatbot on whatsapp. Which would then trigger a simple decision tree and would show you random generated pics of dogs as well as send you daily stoic quotes based on where you are within the decision tree. If you feel that repeatedly watching images of animals are not helpful we would send you a message(sms) with the relevant details on where and how you can avail help to keep things discreet as you could be in a setting where in you might have to open your phone in public and are a bit concerned about your privacy(mental health stigma).
## Additional Prize Categories
Twilio Times Two: Contains usage of twilio messaging channels like sms and whatsapp(webhook too) alongwith twiML.
Impactful Innovators: Helps boost positivity in daily life and provides additional resources if required.
Entertaining Endeavors: CUTE DOG IMAGES!!!

1,898,413 | The 19 tell-tale signs an article was written by AI | “Did AI write this sentence?” That’s become the question of this year. It’s probably our biggest... | 0 | 2024-06-24T05:29:56 | https://dev.to/manojgohel/the-19-tell-tale-signs-an-article-was-written-by-ai-1ecn | chatgpt, javascript, react, tutorial | **“Did AI write this sentence?”** That’s become _the_ question of this year. It’s probably our biggest conundrum since Hamlet got all indecisive while chatting to a hollowed out skull. It’s rolled together all our 21st century doubts and insecurities of Fake News, The Matrix, and misinformation.
If you’re **reading** **content** **online in 2023**, it’s a question you want answered. And if you’re **writing content online in 2023** with the assistance of AI, it’s a question you perhaps _don’t_ want answered. (For the record: I do write this blog. Last I checked, I’m a real human. Jiminy Cricket will vouch for me 🧚🏻♂️).
AI writers are engaged in a cloak-and-dagger routine not dissimilar to Cold War espionage. Think about it: during those times, spies would pass coded messages, employ deception, and use the technology of their era to get the upper hand. Now, our “espionage” is the realm of information and content creation. It’s a Turing Test where some copywriters are assuming false identities and trying to conceal whether AI had a hand in their content.
This digital shadow realm is like a spy-game where creators and consumers need to be discerning, questioning, and aware. With AI capabilities at our fingertips, the cards we hold are more powerful than ever, and knowing when and how to play them is our best defence, and the art of the game.
> _Just want the cold hard tips, no background explanation? I get you. Just scroll to the numbered list “The 19 Tell-Tale Signs of AI Content” below!_
## Why you need to be able to spot AI content yourself
**Readers** shouldn’t be relying on content detectors (or assuming Google will protect them from AI content), and **AI assisted writers** shouldn’t be fretting (or thinking big tech is out to get them). There’s always been chatter that AI will harm SEO, and that search engine algorithms will buffer readers from non-human written content. That isn’t the case, and would be impossible to implement. Language is language, at the end of the day. SEO does prioritize relevance, engagement, and authenticity, so there is some truth to it, but it doesn’t discern AI from human text. Frankly, not all low-quality content is AI. And in the right hands, AI generated content can appear spectacular.
## From AI with Love: The double agents of digital content
I’m pretty good at deciphering AI content. I’m like James Bond at the poker table. I do this for a living; I can spot a good bluff. I don’t go for the obvious tells, like “AI writing is emotionless”. Emotion is a red herring (and cuts out many fine, objective, human writers who craft with precision and subtlety). Some of the most moving writing I’ve read in the last year is [written by AI](https://archive.ph/o/MWeVC/https://www.theguardian.com/technology/2023/jul/18/ai-chatbots-grief-chatgpt).
No, I look for patterns, repetitions, or an overuse of particular phrases or references. I analyze the flow of the content, the choice of examples, the depth and breadth of topics covered in a piece. I use skills I honed across two decades as a copywriter, an assistant editor, academic and examiner.
(There’s scientific evidence for this, [by the way](https://archive.ph/o/MWeVC/https://arxiv.org/pdf/2212.12672.pdf). Some people _are_ better at spotting AI generated content: people with experience in generative AI, immersed in its ebbs and flows, and people trained as close readers).
## What you’ll learn from this article
In this article, I’m going to reveal how to use critical analysis — yes, the type of close reading they teach you at college — to expose AI. Use it for good, use it for evil. I’m not the boss of you. It can help you detect content yourself, or to edit and occlude telltale signs. I will say, _if_ you use it to hide AI content, these tips will improve your writing (that can only be a good thing, right?).
Ultimately, it’s the _quality_ and _readability_ of the content that will matter in the future, and not whether it was a collaboration with machine learning.
Now, let’s take our sunglasses off, and lay our cards face up on the table…
## Why not just use an AI detector?
Why not use a lie detector while we’re at it? Both are notoriously unreliable. But I think most people are a little squeamish about the use of lie detectors.
In fact, AI content detectors are less valid than polygraphs (which get things wrong about 10% to 30% of the time, [depending on the study](https://archive.ph/o/MWeVC/https://pubmed.ncbi.nlm.nih.gov/30284848/)). In July 2023, OpenAI closed down its AI Classifier. It had an embarrassing **_74% fail rate._**
Wharton professor and tech expert Ethan Mollick advises “[AI detectors have high false positive rates, and they should not be used as a result](https://archive.ph/MWeVC#).” However, detectors continue to be used, and to offer false confidence (or false fears, depending which side of the spy-war over AI content you’re on).
(The whole thing is a bit like **Marvel’s Secret Invasion**, where everyone is a suspect. Nobody knows quite who is human behind our screens anymore).

## The shortcomings of AI content detectors
Turnitin was used to evaluate 38 million student essays for AI writing in 3 months alone (April-June 2023), but the company admits their algorithm incorrectly red flags 4% on a sentence-by-sentence level. That’s potentially 1.8 million essays [falsely labelled ‘AI content’](https://archive.ph/o/MWeVC/https://www.reddit.com/r/college/comments/159rexs/falsely_accused_of_using_ai/). An informal experiment by [**The Washington Post**](https://archive.ph/o/MWeVC/https://www.washingtonpost.com/technology/2023/06/02/turnitin-ai-cheating-detector-accuracy/) found Turnitin got it wrong >50% of the time (_n_\=16).
In an [Educator FAQ](https://archive.ph/o/MWeVC/https://help.openai.com/en/collections/5929286-educator-faq) last week, OpenAI addressed the elephant in the room:
> “Do AI detectors work? In short, no. While some (including OpenAI) have released tools that purport to detect AI-generated content, none of these have proven to reliably distinguish between AI-generated and human-content.”
Whether or not they’re good at catching AI, the fact is detectors are in wide use, and if you’re writing with AI you’d be wise to avoid getting red flagged.
## “I don’t use AI, why should I care?”
Ironically, we might have to start using AI content detector evasion tactics for original _human_ work (almost like a writing version of a CAPTCHA, but baked into writing styles and words and syntax to avoid). Again, this might
not be a bad thing, and encourage better rhetoric and writing techniques.
> This is why my list of tell-tale signs of AI to watch out for is useful whether you’re a genuine human writer, or an AI assisted one. It’s about avoiding cliches and adding value.
# What are the best AI content detectors?
Some of the most popular AI content detector programs out there include:
- GPTZERO
- OPENAIWRITER
- CROSSPLAG
- COPYLEAKS
- SAPLING
- CONTENTATSCALE
- ZEROGPT
## Using an AI content detection remover tool (Undetectable.ai)
One way to avoid AI content detectors is to use a generator specifically trained to evade them. The leading tool in this niche is **Undetectable.ai**.
[
## The Truly Undetectable AI Content Writing Tool
### We transform your flagged AI-generated content into premium quality writing that aligns with your brand voice and makes…
undetectable.ai
](https://archive.ph/o/MWeVC/https://undetectable.ai/?fpr=jimtheaiwhisperer)
People can run their AI generated content from any other AI writing tool through **Undetectable.ai**. (Do what you will with this information! I’m merely letting you know it exists in the ever-escalating AI arms race).
[**Undetectable.ai**](https://archive.ph/o/MWeVC/https://undetectable.ai/?fpr=jimtheaiwhisperer) uses a federated multi-model architecture with custom and fine-tuned models to identify text that might trigger alarm bells, removes it, then automatically rephrases it for you. Whether this paraphrasing is more human-like (or simply passing under the AI’s radar) is up to you to decide.
It does allow you to see how the major free and paid AI detectors (including all those listed above) perceive your text. Even though we’ve established that content detectors aren’t successful most of the time (correctly identifying AI content in perhaps only 20–30% of cases), an AI content detection remover like **Undetectable.ai** can help to keep it above suspicion.
## How AI content detectors work (Or don’t, as the case may be!)
There are two main metrics that the AI detection tool kits measure: **perplexity** and **burstiness**. I’ve discussed these in detail previously.
[
## The Dummy Guide to ‘Perplexity’ and ‘Burstiness’ in AI-generated content
### Understanding Language Models: A Simplified Guide
medium.com
](https://archive.ph/o/MWeVC/https://medium.com/the-generator/the-dummy-guide-to-perplexity-and-burstiness-in-ai-generated-content-1b4cb31e5a81)
Basically, “**Perplexity**” refers to how predictable the next word in a sentence is, and “**Burstiness**” refers to the uniformity of the sentences (humans write in fits and starts, with varied sentence lengths, while AI is more consistent). These same metrics are also used to measure performance levels of LLMs.
AI content detectors use a **generative adversarial approach** (don’t worry, I’ll break it down). The detector basically asks: “Would I have written this?” Or rather: “Would I have completed the next word in the sentence this way?”
It’s a game where the adversarial AI (the detector) attempts to predict the next conceivable word. This is actually how AI writes (procedurally, one-word-at-a-time, based on statistical outcomes. If it guesses correctly, it’s logical a similar AI model might have generated the text in the first place.
## The Red Queen: Why we may never be able to reliably detect AI
That’s good as far as it goes, but relies on both AIs using the same lexicon. You can bypass (or “perplex”) any one detector by combining different models. Many AI text generators leverage multiple LLMs, and switch between whichever is most suitable for the use case (**Jasper AI**, for example, uses [OpenAI, Neo X, T5, Bloom, plus a proprietary model](https://archive.ph/o/MWeVC/https://medium.com/p/60536071ca6a)).
Additionally, returning to our Cold War analogy, it’s an arms race. The latest AI language models are increasingly fluent and human-like, which escalates the need for even more powerful means of AI detection (which are trained with the adversarial process). In turn, models like [**Undetectable.ai**](https://archive.ph/o/MWeVC/https://undetectable.ai/?fpr=jimtheaiwhisperer) are trained to bypass _that_ technology. Ultimately, it echoes the Red Queen’s dilemma: “It takes all the running you can do, to keep in the same place.”
Computer scientists warn that “[ultimately, there is nothing special about AI-written text that always distinguishes it from human-written, and detectors can be defeated](https://archive.ph/o/MWeVC/https://arstechnica.com/information-technology/2023/09/openai-admits-that-ai-writing-detectors-dont-work/%23:~:text=Ultimately,%20there%20is%20nothing%20special,abysmal%2026%20percent%20accuracy%20rate.)”. But in my experience: there’s a rhetorical element that shouldn’t be overlooked. That’s where our human intuition comes in.
## The human touch: Why rely on humans for AI detection?
When we’re dealing with language-based AI, a sound knowledge of figures of speech is our best defence. Critical reading is the antidote to AI content. While technology evolves at breakneck speeds, there remains an intrinsic value in the subtle nuances and imperfections of human communication.
In situations where AI models generate descriptive or connective content, they tend to lean on a default mechanism to link ideas or provide reference, even if it’s repetitive or not entirely contextually appropriate. Over-reliance on such devices lends the content an inauthentic air, more reminiscent of a machine echoing human speech patterns than genuine human discourse.
It’s not that AI text doesn’t look like human writing any more; it’s that AI emulates the structure and rhythm of human prose _too_ perfectly, without capturing the spontaneity and unpredictability inherent in genuine human communication. While AI can replicate the framework, it sacrifices the subtle deviations and unique expressions — the irregularities — that make our words come alive, in favour of conformity and the technically correct.
It takes a human, attuned to the intricacies and idiosyncrasies of language, to detect the clunky clichés that algorithms inadvertently produce in their ceaseless pursuit of patterns, consistency, and machine-driven precision.
# The 19 Tell-Tale Signs of AI Content
1. **Caught red handed.** This one is ridiculous, but [it snuck under the noses of the editors of the scientific journal **Nature**](https://archive.ph/o/MWeVC/https://futurism.com/the-byte/paper-retracted-authors-used-chatgpt), so bears repeating: look for the phrases “Regenerate response” or “[as an AI language model, I](https://archive.ph/o/MWeVC/https://www.theverge.com/2023/4/25/23697218/ai-generated-spam-fake-user-reviews-as-an-ai-language-model)”. That’s a sure sign of sloppy copy+paste straight from the chat window.
2. **Textbook perfect spelling.** Because it’s a Large Scale Language Model, AI knows how virtually every word is spelled. Additionally, AI doesn’t make typos, because, well: no fingers. Humans on the other hand…
3. **Middle-of-the-road opinions.** AI-generated content is non-committal or overly neutral. This tendency is because AI models are designed to avoid showing bias, or causing offense, and to cater to a broad audience. The content often adopts an “on the one hand, on the other hand” approach. This is different from a balanced view, which weighs pros and cons but may arrive at a conclusion. AI’s approach is more about hedging its bets.
4. **Overuse of “crucial”.** Once you recognize its prevalence in AI-generated content, the word “crucial” stands out like a sore thumb. A tell-tale sign is the repetitive usage in formulas like, “When you’re \[insert activity; often ‘learning about _x_’ or ‘starting out in _x_’\], it’s crucial to…”. While the term can be, well, _crucial_ in certain contexts, keeping an eye out for repetitive patterns can help differentiate AI text from human writing.
5. **“Delve, Dive, Discover”.** AI has a penchant for particular word patterns. Among these are the use of the verbs “Delve,” “Dive,” and “Discover” in Calls-to-Action (CTAs). Especially recognizable when followed by “…into the exciting world of _x_”. It’s a copywriting technique, but after noticing its frequency in AI-generated content, I’ve personally refrained from it.
6. **“Unlock”**. Another word to eschew. Especially common in AI marketing.
7. **“Ensure”**. AI uses this word more than any reasonable human ever does.
8. **“A dash of _x_”.** This is a colloquialism that I literally only see AI use now.
9. **Overuse of demonstrative pronouns.** High frequency of words like “the, this, these, that, those,” can be an indicator of AI . Daphne Ippolito from **Google Brain** says “[a really easy cue is the word “the” occurs too many times](https://archive.ph/o/MWeVC/https://solvid.co.uk/detect-ai-writing/%23:~:text=%E2%80%9CIf%20you%20have%20enough%20text,scanning%20a%20piece%20of%20text.)”. Demonstrative pronouns are among the most common words in English. Thus, when generating content, AI models tend to use these words frequently as they are statistically common in training data.
10. **Starting sentences with “Remember,…”.** When you come across a piece of content that constantly “reminds” the reader, it could be a sign of AI. The rhetorical device where the writer breaks off to address an abstract concept, asking them to pause and take note of the subsequent point, is called an **Apostrophe**. For example, starting with the word “Remember” followed by a comma, is a favorite apostrophe of AI models. Of course, it’s worth noting that human writers _also_ use the same rhetorical devices. The difference lies in the frequency with which they are applied. An AI might overuse or apply these devices where a human wouldn’t. Remember, it’s all about spotting patterns! (See what I did?)
11. **Metaphor + Tricolon construction.** This pattern typically goes “\[Topic\] is more than just \[basic description or literal interpretation\]; it’s a \[deeper or metaphorical interpretation\] \[verb\] \[a broader context or significance, expressed as a tricolon\].” Example: “_Reading is more than just a hobby; it’s a bridge connecting our society’s history, imagination, and collective consciousness_**_.”_** When you start to notice this rhetorical device — where a metaphor is immediately followed by a tricolon to reinforce its significance — you’ll start to see it everywhere in AI-generated content.
12. **Inability to construct anastrophes**. This one’s a bit harder to explain. An anastrophe is a rhetorical device where the expected order of words in a sentence is reversed. It’s used to create a particular emphasis or poetic impact. At its most obvious, it’s classic Yoda-speak (“Powerful you have become”). Anastrophe also can be spotted in ordinary speech; it’s also used in advertising to make a simple phrase more memorable or achieve immediate recognition. E.g. **“Like a good neighbor, State Farm is there”**.
I’ve written before about how hard it is to get [ChatGPT to reliably write in reverse](https://archive.ph/o/MWeVC/https://medium.com/the-generator/ai-cant-write-sentences-backwards-and-what-this-tells-us-about-llms-4a9ee42c81e2), and what this means for how AI approaches language. This is one of those implications. Although you won’t encounter anastrophe in human writing often, I hope this highlights how straightforward AI is in getting from point A to point B. The text AI generates is procedural, i.e. one word after another, so it’s not good at the forethought required to form an anastrophe. AI tends to avoid doing backflips and linguistic gymnastics. So: “A sentence AI would be unlikely to write is this one”.
13. **AI can’t commit catachresis**. This is another rhetorical device that’s hard to describe, but once you get it, _IYKYK_. AI never writes anything wrong, but humans do, sometimes intentionally. When something’s so wrong it’s right, that’s a catachresis. It’s behind many memes and song lyrics, and it’s catchy. E.g. “Because reasons”, “They don’t think it be like it is, but it do,” and “Set fire to the rain”. Human writers use unconventional grammar and phrasing that deviates from the norm to convey humor, emotion, and originality. AI is so focused on getting things right, it doesn’t know when to break the rules. _Much wow, such grammar._
14. **“In today’s world”.** Even if it’s not an AI artefact, please flush this turd.
15. **“Take your _x_ to the next level”.** Nobody talks like that outside of the Red Bull Cinematic Universe. Seriously, hyped up jargon is rampant in online marketing and advertising. But most real-life conversations steer clear of such hyperbolic statements. AI models, trained on vast amounts of data from the web, have a tendency to over-inflate trendy buzzwords.
16. **“Master”**. Just no. Marketing material might refer to “mastering” a new skill, platform, or tool. But in 2023 it’s outdated. AI didn’t get the memo.
17. **Antithetical Parallelism.** This common rhetorical formula is where two contrasting ideas are juxtaposed in parallel structures. Think of phrases like “From the oldest traditions to the latest trends” or “Whether you’re a seasoned pro or a newcomer to the game”. It lends itself to making content sound balanced and comprehensive (see #4). While human writers use it too, overuse of this structure can be a giveaway of AI.
18. **Limited Use of Parentheses and Em Dashes**: While parentheses and em dashes are common in human writing for creating nuance or offering asides — writers _love_ to drop an em dash for emphasis or squirrel away an extra thought in parentheses (guilty as charged) — AI usually favors more straightforward syntactic constructions. The absence or rarity of punctuation marks can serve as a spoiler that you’re reading AI content.
19. **“If you’re anything like me”**. This is the AI equivalent of the Steve Buscemi meme “How do you do fellow kids”. _Hello_ fellow humans.
**So there you have it!** (Actually, wait, add that cliche too while you’re at it).
The signoff “So there you have it!” is a common copout when AI wraps up articles or blog posts. AI often puts an overly neat bow on complex issues or discussions when tasked to conclude a piece of content, usually followed by a brief restatement of the main points, suggesting an artificial sense of closure that doesn’t do justice to the subject matter. It doesn’t have the contextual understanding or ability to discern nuance like humans do.
## What can I do with this knowledge? Or, Spy vs. Spy
Hopefully the above will help you identify who-is-who. As we’ve discussed, an unnatural frequency of stock phrases, especially in contexts where they don’t quite fit, can serve as a telltale sign that the content was AI-generated.
Yet, this isn’t just about pinpointing who or what wrote the content, but about assessing the added value of the piece. Does it enlighten? Does it engage? Or does it merely parrot recognizable phrases? In the future, it won’t matter whether a text is AI or human written, but if it adds value.
Armed with this understanding, one becomes a content detective, peeling back layers of rhetoric to reveal the true nature of a text. It’s a skill, much like the art of counterintelligence. One learns to pick out allies from foes. The future battlefield isn’t AI vs. human. It’s meaningful vs. meaningless.
## Casino Royale of Clichés: Why AI loves copywriting tropes
Drawing parallels to the world of poker, AI plays its hand based on the cards (data) it’s been dealt. AI tends to gamble on the familiar, resorting to tried-and-true strategies. But why? It comes down to both its training data, and the predictability of procedural generation. AI learns from vast amounts of information, and in the world of writing, clichés are abundant. AI picks up patterns in language from this data, and generates based on “what word comes next in the sentence”. Of course that’s going to repeat and amplify the cliches exisiting in the corpus. It regresses toward a mean. To an AI, these phrases are not tired or overused; they are statistically safe bets.

**Generative Adversarial Network** (GAN) AI detectors focus on a procedural word-by-word basis (much like AI generators themselves). Consequently, they overlook the broader prose. This means they get lost in the prediction of forthcoming words in a sequence and miss challenging the overused tropes that a keen human eye, trained in critical reading, might catch.
My critical-reading method differs from the (fallible) AI content detectors. Unlike the fallible AI content detectors which focus on the likelihood of individual words, my approach zeroes in on common rhetorical figures.

1,898,412 | Step by Step guide to create basic MVVM Application in Android | Machine Coding LLD Android — MVVM-Hilt-Retrofit In this blog we will create a basic mvvm... | 0 | 2024-06-24T05:27:05 | https://medium.com/@khush.panchal123/step-by-step-guide-to-create-basic-mvvm-application-in-android-4c1bd83ac628 | androiddev, android, kotlin, mvvm | > Machine Coding LLD Android — MVVM-Hilt-Retrofit
In this blog we will create a basic mvvm application where user will fetch some data from the api and show it to the UI as a list.
For the sake of this article, we will use OMDb (The Open Movie Database) API to fetch the title and thumbnail image of the movie.
Purpose of this blog is to get started with creating MVVM project following proper architecture which can be used as a base to create any project.
> This blog will help in machine coding round in android interviews.
Out of Scope (We will cover the below topics in upcoming blogs):
- Pagination
- Testing
- Compose
- Offline Caching
- Multiple Screen / Search section
## 1. Understanding the API
- For this article we will be using free open source movie api which can be found at: [https://www.omdbapi.com?s=army&apikey=[yourkey]](https://www.omdbapi.com?s=army&apikey=[yourkey]) (To Get Free API Key go to [https://www.omdbapi.com/](https://www.omdbapi.com/) and then API Key tab) ( I have used the search “army” keyword for the sake of this article so we can get some list of data)
- Json looks like this:
```Json
{
"Search": [
{
"Title": "Hellboy II: The Golden Army",
"Year": "2008",
"imdbID": "tt0411477",
"Type": "movie",
"Poster": "https://m.media-amazon.com/images/M/MV5BMjA5NzgyMjc2Nl5BMl5BanBnXkFtZTcwOTU3MDI3MQ@@._V1_SX300.jpg"
},
{
"Title": "Army of Darkness",
"Year": "1992",
"imdbID": "tt0106308",
"Type": "movie",
"Poster": "https://m.media-amazon.com/images/M/MV5BODcyYzM4YTAtNGM5MS00NjU4LTk2Y2ItZjI5NjkzZTk0MmQ1XkEyXkFqcGdeQXVyNjU0OTQ0OTY@._V1_SX300.jpg"
},
..
..
],
"totalResults": "703",
"Response": "True"
}
```
- For this project we show the list showing image and title of the movie.
## 2. Add dependencies
- Create the new android project in Android Studio and add the following dependency in **app** level `build.gradle.kts` or `build.gradle` file.
```Kotlin
//build.gradle.kts
dependencies {
//Dagger for dependency injection
implementation("com.google.dagger:hilt-android:2.51")
kapt("com.google.dagger:hilt-compiler:2.51")
//Glide for image loading
implementation("com.github.bumptech.glide:glide:4.16.0")
//Retrofit for networking
implementation("com.squareup.retrofit2:retrofit:2.9.0")
implementation("com.squareup.retrofit2:converter-gson:2.9.0")
//ViewModel scope
implementation("androidx.lifecycle:lifecycle-viewmodel-ktx:2.8.2")
}
```
- Additionally for Hilt add the following plugins in **app** level `build.gradle.kts` or `build.gradle` file.
```Kotlin
//build.gradle.kts
plugins {
id("com.android.application")
id("org.jetbrains.kotlin.android")
id("kotlin-kapt") //<-- this one
id("com.google.dagger.hilt.android") // <-- this one
}
```
- Also add following at **root** level `build.gradle.kts` or `build.gradle` file.
```Kotlin
//build.gradle.kts
plugins {
id("com.android.application") version "8.1.4" apply false
id("org.jetbrains.kotlin.android") version "1.9.0" apply false
id("com.google.dagger.hilt.android") version "2.51" apply false //<-- this one
}
```
- Since we will be using view binding for our xml layouts, add the following in **app** level `build.gradle.kts` or `build.gradle` file.
```Kotlin
//build.gradle.kts
android {
..
..
buildFeatures {
viewBinding = true
}
}
```
- Sync the gradle and run your project.
## 3. Create Application class and Add necessary permissions in Manifest file
- Create Application class and add `@HiltAndroidApp` annotation.
```Kotlin
//MainApplication.kt
@HiltAndroidApp
class MainApplication: Application()
```
- Add the name in manifest file.
```XML
<!--AndroidManifest.xml-->
<application
android:name=".MainApplication">
</application>
```
- Add Internet permission in manifest file.
```XML
<!--AndroidManifest.xml-->
<uses-permission android:name="android.permission.INTERNET"/>
```
## 4. Create Folder structure
- Create the following folder structure, with empty folders (“common”, “data/model”, “data/network”, “data/repository”, “di/module”, “ui”, “ui/viewmodel”).
- Check the below final project structure added for reference only, we will create each file step by step.
```
|── MainApplication.kt
├── common
│ ├── Const.kt
│ └── UIState.kt
├── data
│ ├── model
│ │ ├── MainData.kt
│ ├── network
│ │ ├── ApiInterface.kt
│ └── repository
│ └── MainRepository.kt
├── di
│ ├── module
│ │ └── ApplicationModule.kt
├── ui
├── MainActivity.kt
├── MainAdapter.kt
└── viewmodel
├── MainViewModel.kt
```
## 5. Create Model class (Data Layer)
- Create class `MainData.kt` inside “data/model” folder and add the following data class based on the JSON, we are using only title and image.
```Kotlin
//MainData.kt
data class ApiResponse(
@SerializedName("Search")
val dataList: List<MainData>?
)
data class MainData(
@SerializedName("Title")
val title: String,
@SerializedName("Poster")
val poster: String
)
```
## 6. Create Networking interface (Data Layer)
- First create object class `Const.kt` inside “common” folder and add Base url and Api Key.
```Kotlin
//Const.kt
object Const {
const val BASE_URL = "https://www.omdbapi.com/"
const val API_KEY = "your api key"
}
```
- Then create `ApiInterface.kt` class inside “data/network” folder with following function.
```Kotlin
//ApiInterface.kt
interface ApiInterface {
@GET(".")
suspend fun getMoviesData(
@Query("s") s: String = "army",
@Query("apikey") apikey: String = Const.API_KEY
): ApiResponse
}
```
- We are not using OkHttp interceptor for adding api key for of this article but it is recommended to add api key via interceptors.
## 7. Create ApplicationModule (DI Layer)
- Create `ApplicationModule.kt` class inside “di/module” folder for providing Retrofit instance.
```Kotlin
//ApplicationModule.kt
@Module
@InstallIn(SingletonComponent::class)
class ApplicationModule {
@Singleton
@Provides
fun provideNetworkService(): ApiInterface {
return Retrofit
.Builder()
.baseUrl(Const.BASE_URL)
.addConverterFactory(GsonConverterFactory.create())
.build()
.create(ApiInterface::class.java)
}
}
```
## 8. Create Repository class (Data Layer)
- Create `MainRepository.kt` class inside “data/repository” folder that will return flow of list which will be collected by view model.
```Kotlin
//MainRepository.kt
@Singleton
class MainRepository @Inject constructor(
private val apiInterface: ApiInterface
) {
fun getMainData(): Flow<List<MainData>> {
return flow {
emit(
apiInterface.getMoviesData().dataList ?: emptyList()
)
}
}
}
```
## 9. Create ViewModel and UIState (UI Layer)
- First create `UIState.kt` inside “common” folder which is a sealed interface representing the state of UI that will emit and collect between ViewModel and UI component.
```Kotlin
//UIState.kt
sealed interface UIState<out T> {
data class Success<T>(val data: T) : UIState<T>
data class Failure<T>(val throwable: Throwable, val data: T? = null) : UIState<T>
data object Loading : UIState<Nothing>
}
```
- Then create `MainViewModel.kt` inside “ui/viewmodel” folder which extends `ViewModel()` and inject `MainRepository`.
- We use StateFlow to emit data from ViewModel and then collect by UI.
- We use IO dispatcher for network call (For this article we are not injecting dispatcher from outside, but it is recommended to provide from outside).
```Kotlin
//MainViewModel.kt
@HiltViewModel
class MainViewModel @Inject constructor(
private val mainRepository: MainRepository
) : ViewModel() {
private val _mainItem = MutableStateFlow<UIState<List<MainData>>>(UIState.Loading)
val mainItem: StateFlow<UIState<List<MainData>>> = _mainItem
init {
fetchItems()
}
private fun fetchItems() {
viewModelScope.launch {
_mainItem.emit(UIState.Loading)
mainRepository
.getMainData()
.flowOn(Dispatchers.IO)
.catch {
_mainItem.emit(UIState.Failure(it))
}
.collect {
_mainItem.emit(UIState.Success(it))
}
}
}
}
```
## 10. Create Layouts (UI Layer)
- Edit `activity_main.xml` with RecyclerView for showing the list, progress bar and error message.
```XML
<!--activity_main.xml-->
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".ui.MainActivity">
<androidx.recyclerview.widget.RecyclerView
android:id="@+id/rv"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:visibility="gone"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<ProgressBar
android:id="@+id/progress"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:visibility="gone"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<TextView
android:id="@+id/error"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:visibility="gone"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
tools:text="Something went wrong" />
</androidx.constraintlayout.widget.ConstraintLayout>
```
- Create `item_main.xml` layout and put inside “res” folder for single item visible on UI that will be used by Recycler View Adapter.
```XML
<!--item_main.xml-->
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="110dp">
<ImageView
android:id="@+id/iv_item"
android:layout_width="100dp"
android:layout_height="100dp"
android:layout_margin="5dp"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
tools:background="@color/design_default_color_secondary" />
<TextView
android:id="@+id/tv_item"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="5dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintStart_toEndOf="@+id/iv_item"
app:layout_constraintTop_toTopOf="parent"
tools:text="Hey there" />
</androidx.constraintlayout.widget.ConstraintLayout>
```
## 11. Create Adapter class (UI Layer)
- Create `MainAdapter.kt` inside “ui” folder that extends RecyclerView Adapter.
- We use DiffUtil for calculating data diff and bind data.
- We use Glide for loading image into image view.
```Kotlin
//MainAdapter.kt
class MainAdapter : RecyclerView.Adapter<MainAdapter.MainViewHolder>() {
private val items = ArrayList<MainData>()
fun setItems(items: List<MainData>) {
val diffResult = DiffUtil.calculateDiff(MainDiffCallBack(this.items, items))
this.items.clear()
this.items.addAll(items)
diffResult.dispatchUpdatesTo(this)
}
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): MainViewHolder {
return MainViewHolder(
ItemMainBinding.inflate(LayoutInflater.from(parent.context), parent, false)
)
}
override fun getItemCount(): Int {
return items.size
}
override fun onBindViewHolder(holder: MainViewHolder, position: Int) {
holder.bind(items[position])
}
inner class MainViewHolder(private val binding: ItemMainBinding) : ViewHolder(binding.root) {
fun bind(mainData: MainData) {
binding.tvItem.text = mainData.title
Glide.with(itemView.context)
.load(mainData.poster)
.placeholder(com.google.android.material.R.color.design_default_color_secondary)
.into(binding.ivItem)
}
}
}
class MainDiffCallBack(private val oldList: List<MainData>, private val newList: List<MainData>) :
DiffUtil.Callback() {
override fun getOldListSize(): Int {
return oldList.size
}
override fun getNewListSize(): Int {
return newList.size
}
override fun areItemsTheSame(oldItemPosition: Int, newItemPosition: Int): Boolean {
return (oldList[oldItemPosition].title == newList[newItemPosition].title)
}
override fun areContentsTheSame(oldItemPosition: Int, newItemPosition: Int): Boolean {
return oldList[oldItemPosition] == newList[newItemPosition]
}
}
```
## 12. Observe UIState inside MainActivity (UI Layer)
- Drag `MainActivity.kt` file inside “ui” folder.
- We collect Flow from viewmodel and update UI.
```Kotlin
//MainActivity.kt
@AndroidEntryPoint
class MainActivity : AppCompatActivity() {
private lateinit var binding: ActivityMainBinding
private lateinit var adapter: MainAdapter
private val mainViewModel: MainViewModel by lazy {
ViewModelProvider(this)[MainViewModel::class.java]
}
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
binding = ActivityMainBinding.inflate(layoutInflater)
setContentView(binding.root)
adapter = MainAdapter()
collector()
setupUI()
}
private fun setupUI() {
binding.rv.adapter = adapter
binding.rv.layoutManager =
LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false)
binding.rv.addItemDecoration(
DividerItemDecoration(
this,
DividerItemDecoration.VERTICAL
)
)
}
private fun collector() {
lifecycleScope.launch {
repeatOnLifecycle(Lifecycle.State.STARTED) {
mainViewModel.mainItem.collect {
when (it) {
is UIState.Success -> {
binding.progress.visibility = View.GONE
binding.error.visibility = View.GONE
binding.rv.visibility = View.VISIBLE
adapter.setItems(it.data)
}
is UIState.Failure -> {
binding.progress.visibility = View.GONE
binding.error.visibility = View.VISIBLE
binding.rv.visibility = View.GONE
binding.error.text = it.throwable.toString()
}
is UIState.Loading -> {
binding.progress.visibility = View.VISIBLE
binding.error.visibility = View.GONE
binding.rv.visibility = View.GONE
}
}
}
}
}
}
}
```
> Run your application after each step to check everything is working fine.
## High level flow
- Check the below high level flow of how data coming from API and is shown to UI.

This makes it ideal for generating reports, archiving web pages, and automating document workflows, helping to save time and boost productivity. With its extensive API and easy integration into Python projects, IronPDF is an essential tool for developers needing efficient and effective PDF management.
##Step By Step Tutorial:
Let's begin a step-by-step tutorial to generate PDF documents.
###Step # 1: Create or Open Python Project:
The first step is to create a new Python project or open an existing one in your preferred IDE. I am using Microsoft Visual Studio, but you can use any IDE you prefer. The steps will remain the same.
###Step # 2: Install IronPDF:
Next, install the IronPDF library using pip. Keep in mind that IronPDF requires a .NET runtime to be installed on your machine. Run the following command:
```
pip install IronPDF
```
###Step # 3: Create PDF files
IronPDF offers three methods for creating PDF files:
1. Create a PDF document from an HTML string
2. Create a PDF file from a URL
3. Generate PDF Files from an HTML file
Let's explore each method one by one.
###Create a PDF Document from an HTLM String:
Creating a PDF file from an HTML string allows you to dynamically generate documents from formatted text and elements directly within your Python application. This approach is particularly useful for generating reports, invoices, and other documents where content structure is important. Below, we'll demonstrate how to use IronPDF to render HTML content into a PDF file seamlessly.
```
from ironpdf import *
# Apply your license key
License.LicenseKey = "IRONSUITE.ABC.TRIAL-G43TTA.TRIAL.EXPIRES.20.MAY.2025"
renderer = ChromePdfRenderer()
pdfFromHtmlString = renderer.RenderHtmlAsPdf("<h1>Hello World</h1><p>This is a sample PDF created with IronPDF.</p>")
pdfFromHtmlString.SaveAs("sample_pdf.pdf")
```
This code snippet demonstrates how to use IronPDF to convert an HTML string into a PDF file.
1. The first line applies the license key required to use IronPDF, ensuring that the library functions correctly within your application. You may get a free trial license from the [IronPDF Official Website](https://ironpdf.com/#trial-license).
2. The ChromePdfRenderer() initializes an instance of the renderer, which is capable of converting HTML content into a PDF format. This renderer leverages the Chromium browser engine under the hood to accurately render complex HTML structures.
3. renderer.RenderHtmlAsPdf() method takes an HTML string as input and converts it into a PDF document (pdfFromHtmlString).
4. Finally, pdfFromHtmlString.SaveAs("sample_pdf.pdf") saves the generated PDF file with the specified filename ("sample_pdf.pdf") in the current directory.
This approach is useful for dynamically generating PDF documents from HTML content, allowing for flexible document creation and formatting directly within Python applications.
###Create a PDF File from a URL
The following example showcases how to use IronPDF in Python to convert a web page from a specified URL directly into a PDF file. By utilizing IronPDF's ChromePdfRenderer(), you can seamlessly capture and save online content as PDFs, ideal for archiving web pages or integrating web data into printable reports.
```
renderer = ChromePdfRenderer()
pdfFromUrl = renderer.RenderUrlAsPdf("https://en.wikipedia.org/wiki/PDF")
pdfFromUrl.SaveAs("website.pdf")
```
The above line of code uses IronPDF's ChromePdfRenderer() to fetch and convert the web page located at "https://en.wikipedia.org/wiki/PDF" into a PDF document (pdfFromUrl). This method is efficient for capturing and saving web content as PDF files directly within Python applications. In this way, we can easily create PDFs directly from the URL.
The output file is as:
###PDF Generation from HTML files
In this example, we showcase how IronPDF in Python can efficiently generate PDFs by converting the content of an HTML file into new PDF files. By leveraging ChromePdfRenderer(), this code demonstrates the process of creating PDFs directly from structured HTML content. This approach simplifies the task of transforming HTML files into professionally formatted PDFs, suitable for reports, presentations, and digital document archives. Below, we'll illustrate how to implement this functionality seamlessly within your Python projects.
The Content of Sample HTML file is as:
```
<!DOCTYPE html>
<html>
<body>
<h1>Hello Worlds</h1>
<p>This is a sample HTML file for a PDF generation example.</p>
</body>
</html>
```
The Screenshot of the HTML file is:
Here's the code to convert an HTML file into a PDF using IronPDF:
```
renderer = ChromePdfRenderer()
pdfFromHtmlFile = renderer.RenderHtmlFileAsPdf("sample_html_file.html")
pdfFromHtmlFile.SaveAs("html_file_to_pdf.pdf")
```
After executing this code, you can understand how it leverages IronPDF to convert the content of "sample_html_file.html" into a PDF document named "html_file_to_pdf.pdf".
Now, let's explore advanced features by incorporating images, tables, and a watermark into our PDF file.
###Add Images and Table to PDF File:
Incorporating images, tables, or any element into a PDF file is straightforward. Simply include the desired elements in HTML format, then render the HTML to generate the PDF. This method ensures ease of integration and maintains clarity in your document creation process.
Here is the HTML content, I will use for adding images and table in pdf file.
```
<!DOCTYPE html>
<html>
<body>
<h1>Hello Worlds</h1>
<p>This is a sample HTML file for a PDF generation example.</p>
<!DOCTYPE html>
<html>
<head>
<style>
table {
border-collapse: collapse;
width: 100%;
}
tr {
border-bottom: 1px solid #ddd;
}
</style>
</head>
<body>
<h2>This is Sample Table with simple Design</h2>
<table>
<tr>
<th>Firstname</th>
<th>Lastname</th>
<th>Savings</th>
</tr>
<tr>
<td>Peter</td>
<td>Griffin</td>
<td>$100</td>
</tr>
<tr>
<td>Lois</td>
<td>Griffin</td>
<td>$150</td>
</tr>
<tr>
<td>Joe</td>
<td>Swanson</td>
<td>$300</td>
</tr>
<tr>
<td>Cleveland</td>
<td>Brown</td>
<td>$250</td>
</tr>
</table>
<h2>Sample Image</h2>
<img src="C_Sharp.jpg" alt="C Sharp Logo" >
</body>
</html>
```
The screenshot of the above HTML file is as:
I will use the 'Generate PDF from HTML file' method for the advanced features to keep it simple. We will include HTML for tables and images to integrate them into our document. Using HTML as a string directly in Python code can make it messy, so for clarity and simplicity, I will use a separate HTML file to make the PDF generation process simple.
```
renderer = ChromePdfRenderer()
pdfFromHtmlFile = renderer.RenderHtmlFileAsPdf("sample_html_file.html")
pdfFromHtmlFile.SaveAs("html_file_to_pdf.pdf")
```
As you can see, the code for generating PDFs remains the same. You only need to update your HTML to include any element in your PDF file.
###Add Watermark to our Existing PDF file:
Here's how to enhance new PDF documents or existing PDF files by adding a watermark using IronPDF in Python.
```
pdf = PdfDocument.FromFile("html_file_to_pdf.pdf")
pdf.ApplyWatermark("<h2 style='color:red'>SAMPLE WATERMARK</h2>", 30, VerticalAlignment.Top, HorizontalAlignment.Center)
pdf.SaveAs("html_file_to_pdf.pdf")
```
The above code snippet demonstrates how to load a PDF from a file ("html_file_to_pdf.pdf"), apply a watermark using HTML content `("<h2 style='color:red'>SAMPLE WATERMARK</h2>")`, and save the modified PDF with the watermark in place.
##Conclusion:
In conclusion, IronPDF offers robust capabilities for PDF conversion and management, enabling Python developers to create, edit, and manipulate documents with ease. Whether generating reports, incorporating encrypted PDF files, or embedding JPEG images, IronPDF simplifies Python-based PDF creation with its intuitive API and seamless integration.

As a developer, I need to spend as much time as possible writing code, I can’t be spending valuable time writing tests.
A few days ago, I was writing an endpoint to manage an online banking bank account. This required the account to exist in the database, a valid login/password, and data from an external microservice. There are too many things to set up mocks.
Writing automated tests is just a waste of time. When you are working on a critical feature, you can simply:
- Develop
- Test/Debug locally
- Set data in the local database
- Disabling the endpoint authentication so you don’t have to set data on the authentication system
- Put a breakpoint on the external API call to replace the data returned.
- Or, in case of time-sensitive features, like late appointments or payment reminders, you can wait for the reminders to kick in.
After each change, we can repeat the process above for our feature and all other possible scenarios we might have impacted. 20 scenarios to test? No problem.
As the process of retesting the application takes some time, you should only do this once a day or every couple of days. This way, you don’t waste time and can deliver more.
## Confident developers
Tests are also a confidence problem; only developers who don’t trust their abilities have to write tests. If you are a professional developer, you can simply develop and push it to production, without even debugging locally, as you trust your abilities.
TDD is also not the only way to add tests. Even if I wanted an automated test coverage, we could just add the tests after the code was written. As a confident developer, I am sure to cover all the behaviours I wrote code for hours on end.
😂😂😂😂
As a parody as it is, this is based on arguments I’ve heard in the past on how TDD doesn’t work or is not worth it.
Let’s put a side the TDD practice, let’s focus on what’s the alternative?
- To manually test things?
- To delegate testing responsibilities and end up with a long feedback loop?
- To deploy code without testing?
- To write tests after the implementation and get partial coverage?
TDD is not a silver bullet, but I can confidently say it could be applied well and pay dividends in 80% of professional development cases. Exceptions don’t disprove the rule.
TDD is a skill set that you add to your toolbox, and you can decide when to use it as appropriate. Before throwing chairs at it, I recommend learning the practice properly. What is TDD? Who invented it? What are the rules that define whether you are doing TDD or not? | manojgohel |

#### Introduction
Hey there! Today, we're going to learn about some cool tools that help people make computer programs work better and faster. Think about how a team of people works together to make a movie. Each person has their own job, and they use different tools to help make the movie. In the world of computers, we use tools like Jenkins, Docker, Kubernetes, Ansible, and Terraform to help us build and manage software. Let’s explore each tool and see how they work!
### Popular DevOps Tools
#### 1. Jenkins
**What It Does:**
- **Automates Tasks:** Jenkins is like a machine that helps movie makers by automating repetitive tasks like editing scenes or adding special effects.
- **Plugins:** Jenkins can be customized with different add-ons to help with various jobs, like adding different special effects to the movie.
- **Pipeline:** Imagine an assembly line that moves movie scenes through different stages like filming, editing, and finalizing.
**Why We Use It:**
Jenkins helps people make sure their computer programs work properly by automatically building and testing them. It's like having a machine that helps put together and check scenes in a movie to ensure they look great.
**Example:**
Imagine you're making a movie. Jenkins can automatically edit the scenes, add special effects, and check if everything is perfect.
#### 2. Docker
**What It Does:**
- **Containerization:** Docker packages your movie files and all the necessary software into containers, ensuring everything you need is in one place.
- **Lightweight:** These containers are easy to carry around and don’t take up much space.
- **Portability:** You can take these containers anywhere and start working on your movie right away.
**Why We Use It:**
Docker helps developers ensure that their programs can run anywhere without problems. It's like packing all the movie files and editing software you need into a portable hard drive.
**Example:**
Imagine you have a portable hard drive with all the files needed to edit a movie. Docker makes sure you can take that hard drive to any computer, and you'll have everything you need to continue working on the movie just like at home.
#### 3. Kubernetes
**What It Does:**
- **Orchestration:** Kubernetes is like a director who coordinates all the different teams in a movie production, making sure everyone works together smoothly.
- **Self-Healing:** If a team member gets sick or makes a mistake, Kubernetes finds a replacement or fixes the mistake quickly.
- **Scalability:** If more scenes need to be filmed quickly, Kubernetes can bring in more team members to handle the increased workload.
**Why We Use It:**
Kubernetes helps manage lots of containers, making sure they all work together nicely. It’s like having a director who ensures every part of the movie production is running correctly and on time.
**Example:**
Imagine a movie set with multiple teams filming different scenes. Kubernetes makes sure each team has the right equipment and instructions, and if a team needs help, Kubernetes finds someone to assist.
#### 4. Ansible
**What It Does:**
- **Agentless:** Ansible doesn’t need any special tools installed on the other computers it manages.
- **Simple Language:** Uses easy-to-understand instructions to tell teams what to do.
- **Idempotency:** Ensures the same result every time, like following a reliable script.
**Why We Use It:**
Ansible helps automate tasks like setting up and configuring computers, just like giving all the movie teams the same script to follow.
**Example:**
Imagine you have a script for filming a scene. Ansible can give this script to every team, and they’ll all film the same scene without any mistakes.
#### 5. Terraform
**What It Does:**
- **Infrastructure as Code:** Terraform lets you describe your movie set layout and equipment setup using a special language.
- **Multi-Provider:** Supports different types of movie sets (like action, comedy, or drama).
- **Execution Plans:** Shows you a plan of what will happen before you start filming.
**Why We Use It:**
Terraform helps create and manage large setups, making sure everything is built correctly and efficiently. It’s like having a detailed plan for setting up a new movie set that everyone can follow.
**Example:**
Imagine you have a blueprint for setting up a new movie set. Terraform shows you the plan and lets you know what equipment you need and how to arrange everything step-by-step.
### Conclusion
These DevOps tools help people build and manage software just like different tools help make a movie. Jenkins is great for automating tasks, Docker for packaging, Kubernetes for managing teams, Ansible for giving instructions, and Terraform for planning big projects. By understanding these tools, you can see how they help create amazing software, just like movie-making tools help create blockbuster films! | dilshavijay |
1,898,398 | Why I Always Choose to Use Types Instead of Interfaces？ | In TypeScript, both Types and Interfaces are used to define the types of objects. However, they have... | 0 | 2024-06-24T05:12:09 | https://dev.to/manojgohel/why-i-always-choose-to-use-types-instead-of-interfaces-2l3k | interfacesegregation, typescript, webdev, javascript | In TypeScript, both Types and Interfaces are used to define the types of objects. However, they have different uses and features. Both can help developers constrain the types of variables and objects when writing code, thereby reducing errors and improving code readability.
- **_type:_** `type` is a type alias used to define an alias for any type. This is not limited to object types; it can also define primitive types, union types, intersection types, etc. For example:
// Define an alias for a primitive type
```
type Name = string;
// Define an alias for an object type
type User = {
id: number;
name: string;
};
// Define a union type
type Status = 'active' | 'inactive' | 'suspended';
// Define an intersection type
type Person = {
name: string;
} & {
age: number;
};
```
- **interface:** `interface` is used to define the structure of an object and can be extended by inheriting other interfaces. `interface` is mainly used to define the structure and implementation constraints of classes. For example:
```
// Define an object interface
interface User {
id: number;
name: string;
}
// Interface inheritance
interface Admin extends User {
role: string;
}
// Interface implementation in a class
class Person implements User {
id: number;
name: string;
constructor(id: number, name: string) {
this.id = id;
this.name = name;
}
}
```
# Why prioritize using Types?
In TypeScript, there has been an ongoing debate about whether to use Types or Interfaces for type definitions. Although both can be used to create reusable structures for variables, function parameters, and return values, in most cases, we should prioritize using Types. Here are four main reasons:
## **1\.** Support for Union Types
`type` can define union types, which is something `interface` cannot do.
```
type StringOrNumber = string | number;
```
## **2\.** Support for String Literal Types
```
`type` can define string literal types, which can be very useful in certain scenarios.
type Status = 'success' | 'error' | 'pending';
## **3\.** Immutability
`type` is immutable, meaning once defined, it cannot be changed through extension or merging. This ensures the stability and consistency of the type. In contrast, `interface` can be declared multiple times and merged, which might lead to unexpected behaviors.
type User = {
email: string;
}
// Will cause an error because it cannot be declared multiple times
type User = {
password: string;
}
interface User {
email: string;
}
// The two declarations will be merged, and the final User interface will contain both email and password properties.
interface User {
password: string;
}
```
## **4\.** Support for Conditional Types
`type` supports conditional types, which can be used for more complex type definitions.
```
type IsString<T> = T extends string ? 'yes' : 'no';
```
In summary, prioritizing `type` provides greater flexibility and powerful type expression capabilities, especially when dealing with complex types and logic. `type` can better meet your needs. Therefore, I always choose to use `type` first, as it enhances code type safety and maintainability. | manojgohel |

React.js, a popular JavaScript library for building user interfaces, offers a flexible approach to managing forms and user inputs through controlled and uncontrolled components. Understanding the distinction between these two types of components is essential for developers aiming to create efficient and maintainable code. In this article, we'll explore what controlled and uncontrolled components are, their key differences, use cases, and best practices.

## 1. Introduction to Components in React.js
React.js is built around the concept of components, which are reusable pieces of UI that encapsulate their own structure, logic, and styling. Components can be either **stateful** or **stateless**:
- **Stateful Components** (Class components or Functional components with hooks) manage and store state.
- **Stateless Components** (Functional components) do not manage state internally.
Form handling in React is typically managed through controlled and uncontrolled components, each offering unique advantages and approaches.
---
## 2. Controlled Components
### Definition and Characteristics
A **controlled component** in React is a form element whose value is controlled by the state of a React component. This means that the state of the component dictates the value of the form element. Every state change is handled through a React event handler, making the React state the "single source of truth" for the form element.
### Characteristics of Controlled Components:
- **State Management:** The component’s state controls the form data.
- **Event Handling:** Updates to the form element's value are handled by React events.
- **Single Source of Truth:** The form element's value is synced with the state.
### Advantages
1. **Predictable State Management:** Since the state of the form elements is stored in React state, it becomes easier to manage and predict the behavior of the form.
2. **Validation:** Form validation can be easily handled by adding logic to the event handlers.
3. **Instant Feedback:** The form elements can provide immediate feedback to users by updating the state.
### Examples
Here’s an example of a controlled component:
```jsx
import React, { useState } from 'react';
function ControlledForm() {
const [name, setName] = useState('');
const handleChange = (event) => {
setName(event.target.value);
};
const handleSubmit = (event) => {
event.preventDefault();
alert('A name was submitted: ' + name);
};
return (
<form onSubmit={handleSubmit}>
<label>
Name:
<input type="text" value={name} onChange={handleChange} />
</label>
<input type="submit" value="Submit" />
</form>
);
}
export default ControlledForm;
```
In this example, the input element's value is controlled by the `name` state, and any changes to the input are handled by the `handleChange` function.
---
## 3. Uncontrolled Components
### Definition and Characteristics
An **uncontrolled component** in React is a form element that maintains its own internal state. The React component does not directly manage the form element’s state; instead, it accesses the value using references (refs).
### Characteristics of Uncontrolled Components:
- **Direct DOM Access:** The value is accessed directly from the DOM using refs.
- **Less Code:** Fewer state variables and event handlers are needed.
- **Initial Values:** Default values can be set using the defaultValue attribute.
### Advantages
1. **Simplicity:** Uncontrolled components require less boilerplate code since there is no need to manage state for form elements.
2. **Ease of Integration:** They can be easier to integrate into existing codebases or third-party libraries where the form handling logic is already defined.
### Examples
Here’s an example of an uncontrolled component:
```jsx
import React, { useRef } from 'react';
function UncontrolledForm() {
const nameInput = useRef(null);
const handleSubmit = (event) => {
event.preventDefault();
alert('A name was submitted: ' + nameInput.current.value);
};
return (
<form onSubmit={handleSubmit}>
<label>
Name:
<input type="text" ref={nameInput} />
</label>
<input type="submit" value="Submit" />
</form>
);
}
export default UncontrolledForm;
```
In this example, the input element's value is accessed using a ref, making it an uncontrolled component.
---
## 4. Key Differences Between Controlled and Uncontrolled Components
### Controlled Components:
- **State Management:** Managed by React state.
- **Event Handling:** Updates via React event handlers.
- **Use Case:** When form validation, conditional rendering, or complex form interactions are needed.
### Uncontrolled Components:
- **State Management:** Managed by the DOM.
- **Event Handling:** Accessed via refs.
- **Use Case:** Simple forms or when integrating with non-React code.
### Summary of Differences:
| Feature | Controlled Components | Uncontrolled Components |
|------------------------|--------------------------------------|---------------------------------------|
| State Management | React state | DOM |
| Event Handling | React event handlers | Refs |
| Code Complexity | More boilerplate | Less boilerplate |
| Use Cases | Complex forms, validation | Simple forms, existing integrations |
| Default Values | Set through state | Set through `defaultValue` attribute |
---
## 5. When to Use Controlled vs. Uncontrolled Components
### Controlled Components:
- **Form Validation:** When you need to validate user input in real-time.
- **Complex Forms:** When forms require conditional rendering or interdependent inputs.
- **Immediate Feedback:** When user interactions need to update the UI immediately.
### Uncontrolled Components:
- **Simple Forms:** For basic forms where validation and interactivity are minimal.
- **Third-Party Integrations:** When integrating with libraries or frameworks that handle their own form logic.
- **Less Overhead:** When simplicity and minimal state management are desired.
---
## 6. Best Practices for Using Controlled and Uncontrolled Components
### Best Practices for Controlled Components:
1. **State Management:** Keep state as simple and minimal as possible.
2. **Performance Optimization:** Avoid excessive re-renders by using techniques like memoization and shouldComponentUpdate.
3. **Form Validation:** Centralize validation logic to maintain consistency.
4. **Modular Code:** Break down large forms into smaller, manageable components.
### Best Practices for Uncontrolled Components:
1. **Use Refs Wisely:** Ensure refs are used appropriately to avoid accessing the DOM too frequently.
2. **Default Values:** Utilize `defaultValue` for setting initial values without relying on state.
3. **Minimal State:** Only use uncontrolled components for forms that do not require complex state management.
---
## 7. Common Pitfalls and How to Avoid Them
### Pitfalls in Controlled Components:
1. **Excessive State Updates:** Frequent state updates can lead to performance issues. Optimize state management and minimize re-renders.
2. **Complex State Logic:** Avoid overly complex state logic by breaking it down into smaller, reusable functions or hooks.
### Pitfalls in Uncontrolled Components:
1. **Inconsistent State:** Relying on the DOM for state can lead to inconsistencies, especially in complex forms.
2. **Limited Validation:** Uncontrolled components are harder to validate, making it challenging to provide real-time feedback.
---
## 8. Conclusion
Understanding the differences between controlled and uncontrolled components in React.js is crucial for developing efficient and maintainable applications. Controlled components offer a more predictable and manageable approach to form handling, making them ideal for complex forms and real-time validation. Uncontrolled components, on the other hand, provide simplicity and ease of integration, making them suitable for basic forms and third-party integrations.
By leveraging the strengths of each type of component and following best practices, developers can create robust, user-friendly forms that enhance the overall user experience. Whether you choose controlled or uncontrolled components, the key is to understand their use cases and apply them appropriately in your projects.

1,898,394 | How to Extract Table From PDF in Python | How to Extract Tables from PDF in Python - Full Tutorial Create or open a Python project... | 0 | 2024-06-24T05:03:17 | https://dev.to/mhamzap10/how-to-extract-table-from-pdf-in-python-45ek | python, ironpdf, softwaredevelopment, webdev | ##How to Extract Tables from PDF in Python - Full Tutorial
1. Create or open a Python project to begin.
2. Install the IronPDF library using pip.
3. Load the PDF file you want to extract data from.
4. Extract text from the PDF file.
5. Filter and extract tabular data from the extracted text.
Extracting tables from [PDFs](https://www.adobe.com/acrobat/about-adobe-pdf.html) can be challenging due to the lack of a standardized structure in PDF documents. However, with the help of libraries like [IronPDF](https://ironpdf.com/python/), we can efficiently extract tables and data from PDFs. IronPDF is a powerful tool that allows developers to manipulate and read PDF files easily.
In this tutorial, we'll walk through the steps to extract tables from PDFs using IronPDF in [Python](https://www.python.org/). We'll cover the installation process, basic usage, and a practical example to extract tables from a sample PDF.
##IronPDF for Python:
[IronPDF](https://ironpdf.com/python/) is a robust and versatile Python library designed to handle a wide range of PDF manipulation tasks, including the [creation](https://ironpdf.com/python/examples/using-html-to-create-a-pdf/), [editing](https://ironpdf.com/python/examples/editing-pdfs/), and [extraction](https://ironpdf.com/python/examples/extract-pdf-text/) of content. It boasts features such as converting [HTML to PDF](https://ironpdf.com/python/examples/file-to-pdf/), [merging multiple PDFs](https://ironpdf.com/python/examples/merge-pdfs/), [adding watermarks](https://ironpdf.com/python/examples/pdf-watermarking/), and extracting [text](https://ironpdf.com/python/examples/extract-pdf-text/) and [images](https://ironpdf.com/python/examples/extract-pdf-image/) with precision. One of its standout capabilities is the ability to maintain the integrity and formatting of complex PDF documents during manipulation. Ideal for generating reports, archiving web pages, and automating document workflows, IronPDF streamlines PDF-related processes, saving time and enhancing productivity. Its comprehensive API and ease of integration into Python projects make it a valuable tool for developers seeking to manage PDFs efficiently and effectively.
##Step By Step Tutorial:
Let's begin a step-by-step tutorial for extracting tabular data from a PDF file.
###Step # 1: Create or Open Python Project:
The first step is to create a Python Project or open an existing one in your favorite IDE. I am using Microsoft Visual Studio 2022. You may use any as per your preference. The process will remain the same for each IDE.
###Step # 2: Install IronPDF Library:
Next, you need to install the IronPDF library. You can do this via pip. Note that IronPDF requires a .NET runtime to be installed on your machine.
```
pip install IronPDF
```
###Step # 3: Extract Text from PDF File:
To extract tabular data from a PDF using IronPDF in Python, the first essential step is to extract all the text from the PDF. This extracted text can then be filtered to isolate and process the table data. In the following code snippet, we demonstrate how to load a PDF document, apply a license key, and extract all the text content using IronPDF. This foundational step is crucial for further processing to identify and Table Extraction from the document.
The following PDF File is used in this tutorial.
```
from ironpdf import *
# Apply your license key
License.LicenseKey = "IRONSUITE.ABC.TRIAL-G43TTA.TRIAL.EXPIRES.20.MAY.2025"
# Load a PDF File
pdf = PdfDocument("TabularData.pdf") # File Location
# Extract all text from the PDF
text = pdf.ExtractAllText();
print(text)
```
This Python code starts by importing the necessary components from the IronPDF library. It then sets the license key to enable full functionality. The PdfDocument class is used to load a PDF file named "TabularData.pdf". Finally, the ExtractAllText method is called to retrieve all the text content from the PDF, which is then printed to the console. This initial extraction is critical as it provides the raw text data from which PDF tables can be subsequently identified and processed.
###Step # 4: PDF Table Extraction from Extracted Text Content
To further refine the extraction of tabular data from a PDF, we need to filter out irrelevant lines and focus on the ones that likely contain the table data. The following Python code demonstrates how to split the extracted text into individual lines and then filter these lines based on the presence of a period (.), which is typically not found in table data. This helps in isolating potential table rows from the complete text extraction. Once isolated, this data can be easily converted to an Excel file for better analysis and storage.
```
# Split the extracted text by newline characters
text_list = text.split("\n")
# Iterate through each item in the text list
for text_item in text_list:
# If the item contains a period, skip it
if '.' in text_item:
continue
else:
# Print the item
print(text_item)
```
This code starts by splitting the extracted text into separate lines using the newline character as a delimiter. It then iterates through each line, checking for the presence of a period. Lines containing periods are skipped, while the remaining lines are printed. This process effectively isolates lines that are more likely to contain table data, streamlining the task of identifying and extracting relevant information from the PDF.
###Extracting Tabular Data from Scanned PDF Pages
Consider a scenario where you have multiple PDF pages containing scanned images of documents, and you need to extract tabular data from these pages and save it to an Excel file. In such cases, Optical Character Recognition (OCR) can be used to convert scanned images into text, and then the above method can be applied to isolate and extract table data.
Here’s an example to handle such a case:
####Perform OCR on Scanned Images:
Use a library like [IronOCR](https://ironsoftware.com/csharp/ocr/) to perform OCR on [scanned images](https://ironsoftware.com/csharp/ocr/how-to/input-images/) within the PDF.
####Extract Text and Filter Table Data:
Use the same technique as above to split the text and filter out the table data.
####Save Data to an Excel File:
Use [IronXL](https://ironsoftware.com/python/excel/) to save the filtered data to an [Excel file](https://ironsoftware.com/python/excel/examples/create-excel-spreadsheet/).
##Conclusion:
Extracting tables from PDFs in Python using IronPDF is a robust and efficient way to manage and manipulate PDF content. By following the steps outlined in this tutorial, you can easily extract text from PDFs, filter out irrelevant content, and isolate tabular data for further processing. This approach is particularly useful for digitizing data from documents, generating reports, and automating document workflows.

**Signalize:**
- Leverages modern **ES modules** and **import maps**.
- Imports only a small **2 KB core**, allowing **you to decide what to import and when**.
The goal is to provide functionality similar to modern frameworks like Vue, Svelte, Solid, and Qwik, but with minimal JavaScript, the smallest possible learning curve, a simple codebase, no dependencies, and no need for a JavaScript backend.
## Signalize in a Nutshell
Let's start with a simple example of how Signalize works:
- [Signalize](https://signalizejs.com) is split into several JavaScript modules.
- Each module provides different functionality.
- To use Signalize, you need to define an import map first.
- Then, you import the core and create a new Signalize instance.
- This new instance will provide you with the `resolve` function for loading modules.
- Every time you need some functionality, you import it using the resolve function.
- Signalize internally reuses modules and automatically loads dependencies in the correct order to keep the framework small.
```html
<!-- 1. Configure the importmap -->
<script type="importmap">
{
"imports": {
"signalizejs": "https://cdn.jsdelivr.net/npm/signalizejs@latest/+esm",
"signalizejs/mutation-observer": "https://cdn.jsdelivr.net/npm/signalizejs@latest/mutation-observer/+esm",
"signalizejs/dom/ready": "https://cdn.jsdelivr.net/npm/signalizejs@latest/dom/ready/+esm",
"signalizejs/event": "https://cdn.jsdelivr.net/npm/signalizejs@latest/event/+esm"
}
}
</script>
<script type="module">
// 2. Import the Signalize core
import Signalize from 'signalizejs';
// 3. Create a new Signalize instance
const { resolve } = new Signalize();
// 4.1 Resolve the Event module because we need the "on" function
// 4.2 The Event module will automatically import the Mutation Observer module
const { on } = await resolve('event', 'dom/ready');
// 5. Use the on function
on('dom:ready', () => alert('Hello World!'));
</script>
```
## The Ecosystem
The [Signalize](https://signalizejs.com) ecosystem currently contains 25 modules focused on solving web development problems such as reactivity, web components, Ajax, SPA, error logging, and various utilities. The number of modules will definitely grow.
Here is a list of a few of them:
- **Signals & Reactivity**: [signal](https://signalizejs.com/docs/modules/signal), [bind](https://signalizejs.com/docs/modules/bind)
- [Directives](https://signalizejs.com/docs/modules/directives)
- [Web Components](https://signalizejs.com/docs/modules/component)
- [SPA](https://signalizejs.com/docs/modules/spa)
- [Dialogs](https://signalizejs.com/docs/modules/dialog)
- [Logger](https://signalizejs.com/docs/modules/logger)
- **Web Perf**: [Task](https://signalizejs.com/docs/modules/task)
- **Utils**: [Ajax](https://signalizejs.com/docs/modules/ajax)
## The Mindset
The basic idea is to import only what you need. Not everything needs to be a complex app with tons of features:
- **I need some simple reactivity**: Use the [Signals](https://signalizejs.com/docs/modules/signal) and [Binding](https://signalizejs.com/docs/modules/bind) modules.
- **I have a carousel with dynamic products**: Use the [Ajax](https://signalizejs.com/docs/modules/ajax) module and manually redraw [Snippets](https://signalizejs.com/docs/modules/snippets).
- **I need reusable components**: Use [Web Components](https://signalizejs.com/docs/modules/component)
- **I need more complex forms**: Import [Directives](https://signalizejs.com/docs/modules/directives)
- **I want to turn my website into an SPA**: Add the [SPA](https://signalizejs.com/docs/modules/spa) module.
### A simple example with Signals & Reactivity.

document.querySelector('button').addEventListener(
'click',
() => number(number() + 1)
);
bind(document.querySelector('span'), { text: number });
</script>
```
## A simple example with Astro.build
Do you like Astro.build? It converts JavaScript into ES modules, so Signalize works very well with Astro. I wrote a guide on [how to use Signalize in Astro](https://signalizejs.com/docs/installation/astro).
Bellow is a simplified example:
**1 - Install Signalize:**
```
npm i signalizejs
```
**2 - Create `src/assets/layout.js`**
```js
import Signalize from 'signalizejs';
export const signalize = new Signalize();
```
**3 - Create `src/layouts/main.astro`**
```html
---
// 1. Get signalizejs url
import signalize from 'signalizejs?url';
// 2. Get event module url. This applies for all modules you will need.
import eventModuleUrl from 'signalizejs/event?url';
// 3. Define importmap
const importMap = JSON.stringify({
imports: {
// 4. Configure necessary modules
'signalizejs/event': eventModuleUrl,
// Other modules you need
}
});
---
<html>
<head>
<!-- 5. Embed the import map -->
<script type="importmap" :html={importMap}></script>
<!-- 6. Create a global Signalize instance -->
<script>
import "../assets/layout.js";
</script>
</head>
<body>
<slot />
</body>
</html>
```
**4 - Create `src/pages/index.astro`**
```html
---
// src/pages/index.astro
import MainLayout from '../layouts/main.astro';
---
<MainLayout>
<script>
import { signalize } from '../assets/layout.js';
const { on } = await signalize.resolve('event');
</script>
</MainLayout>
```
## Let me know what you think!
If you like the idea, let me know by [starring the Signalize repo](https://github.com/signalizejs/signalize).
I welcome any feedback because Signalize is a new library and there is definitely room for improvement. 🙂
## Stay in Touch!
I plan to write about the reactivity inspired by Solid and Angular Signals, the bindings and directives inspired by Svelte, and the ES module loader for dependency injection inspired by Qwik's loader.
If you want to get inspired for your next project or learn something new, it's a great place to start.

Even I declare myself guilty of recommeding it too.
The Clean Code is a good starting point. Don't take me wrong. I read it and studied. And you should too.
But I prefer and recommend another one in the "Clean" series: **The Clean Coder**.
"The Clean Coder" isn't about programming. It's about the professional practice of programming. It covers everything from what professionalism is to testing strategies, pressure, and time management.
These are four valuable lessons from "The Clean Coder":
1. Estimates aren't a single number of days, but a range.
2. You don't have to say yes to everything. But you should find a creative way to make a yes possible.
3. There is no "trying." Say no and offer a trade-off. An "I will try" is taken as yes and people expect outcomes.
4. It could consider unprofessional not to use Test-Driven Development
But if I could summarize the whole book into a single quote, it would be this:
"_Your career is your responsibility, not your employer's_"

JavaScript arrays come equipped with a powerful suite of methods that can streamline your code and elevate your programming efficiency. In this guide, we'll dive into the advanced array methods that every JavaScript developer should master. By the end, you'll understand how to harness these methods to write cleaner, more efficient, and more expressive code.
### Understanding the Basics
Before we delve into the advanced methods, let's quickly recap the fundamentals. Arrays in JavaScript are used to store multiple values in a single variable. They provide a range of methods for adding, removing, and manipulating elements. Understanding these basics will serve as a foundation for exploring more complex methods.
### Advanced Array Methods
#### 1. **Array.prototype.map()**
**What It Does:**
Creates a new array populated with the results of calling a provided function on every element in the calling array.
**Syntax:**
```javascript
const newArray = array.map(callback(element[, index[, array]])[, thisArg])
```
**Example:**
```javascript
const numbers = [1, 2, 3, 4];
const doubled = numbers.map(num => num * 2);
console.log(doubled); // Output: [2, 4, 6, 8]
```
The `map()` method applies the given function to each element of the array and returns a new array with the results. This is useful for transforming data without modifying the original array.
#### 2. **Array.prototype.filter()**
**What It Does:**
Creates a new array with all elements that pass the test implemented by the provided function.
**Syntax:**
```javascript
const newArray = array.filter(callback(element[, index[, array]])[, thisArg])
```
**Example:**
```javascript
const numbers = [1, 2, 3, 4];
const even = numbers.filter(num => num % 2 === 0);
console.log(even); // Output: [2, 4]
```
The `filter()` method creates a new array with all elements that pass the test defined in the callback function. This is useful for extracting a subset of elements from an array.
#### 3. **Array.prototype.reduce()**
**What It Does:**
Executes a reducer function (that you provide) on each element of the array, resulting in a single output value.
**Syntax:**
```javascript
const result = array.reduce(callback(accumulator, currentValue[, index[, array]])[, initialValue])
```
**Example:**
```javascript
const numbers = [1, 2, 3, 4];
const sum = numbers.reduce((total, num) => total + num, 0);
console.log(sum); // Output: 10
```
The `reduce()` method applies a function against an accumulator and each element in the array (from left to right) to reduce it to a single value. It’s powerful for calculations and aggregations.
#### 4. **Array.prototype.find()**
**What It Does:**
Returns the value of the first element in the provided array that satisfies the provided testing function.
**Syntax:**
```javascript
const found = array.find(callback(element[, index[, array]])[, thisArg])
```
**Example:**
```javascript
const numbers = [1, 2, 3, 4];
const found = numbers.find(num => num > 2);
console.log(found); // Output: 3
```
The `find()` method returns the first element that passes the test defined in the callback function. It’s useful for quickly finding a specific element in an array.
#### 5. **Array.prototype.some()**
**What It Does:**
Tests whether at least one element in the array passes the test implemented by the provided function.
**Syntax:**
```javascript
const result = array.some(callback(element[, index[, array]])[, thisArg])
```
**Example:**
```javascript
const numbers = [1, 2, 3, 4];
const hasEven = numbers.some(num => num % 2 === 0);
console.log(hasEven); // Output: true
```
The `some()` method checks if at least one element in the array satisfies the condition specified in the callback function. It’s useful for validation and checks.
#### 6. **Array.prototype.every()**
**What It Does:**
Tests whether all elements in the array pass the test implemented by the provided function.
**Syntax:**
```javascript
const result = array.every(callback(element[, index[, array]])[, thisArg])
```
**Example:**
```javascript
const numbers = [1, 2, 3, 4];
const allEven = numbers.every(num => num % 2 === 0);
console.log(allEven); // Output: false
```
The `every()` method tests whether all elements in the array pass the test implemented by the provided function. It’s useful for ensuring all elements meet a certain condition.
#### 7. **Array.prototype.flat()**
**What It Does:**
Creates a new array with all sub-array elements concatenated into it recursively up to the specified depth.
**Syntax:**
```javascript
const newArray = array.flat(depth)
```
**Example:**
```javascript
const arr = [1, 2, [3, 4, [5, 6]]];
const flattened = arr.flat(2);
console.log(flattened); // Output: [1, 2, 3, 4, 5, 6]
```
The `flat()` method creates a new array with all sub-array elements concatenated into it recursively up to the specified depth. This is useful for flattening nested arrays.
#### 8. **Array.prototype.flatMap()**
**What It Does:**
First maps each element using a mapping function, then flattens the result into a new array.
**Syntax:**
```javascript
const newArray = array.flatMap(callback(currentValue[, index[, array]])[, thisArg])
```
**Example:**
```javascript
const arr = [1, 2, 3];
const result = arr.flatMap(num => [num, num * 2]);
console.log(result); // Output: [1, 2, 2, 4, 3, 6]
```
The `flatMap()` method first maps each element using a mapping function, then flattens the result into a new array. It’s useful for combining mapping and flattening into a single step.
#### 9. **Array.prototype.includes()**
**What It Does:**
Determines whether an array includes a certain value among its entries, returning true or false.
**Syntax:**
```javascript
const result = array.includes(valueToFind[, fromIndex])
```
**Example:**
```javascript
const numbers = [1, 2, 3, 4];
const includesThree = numbers.includes(3);
console.log(includesThree); // Output: true
```
The `includes()` method checks if an array contains a certain value among its entries. It’s useful for existence checks.
#### 10. **Array.prototype.sort()**
**What It Does:**
Sorts the elements of an array in place and returns the sorted array. The default sort order is according to string Unicode code points.
**Syntax:**
```javascript
array.sort([compareFunction])
```
**Example:**
```javascript
const numbers = [4, 2, 3, 1];
numbers.sort((a, b) => a - b);
console.log(numbers); // Output: [1, 2, 3, 4]
```
The `sort()` method sorts the elements of an array in place and returns the sorted array. By default, it sorts elements as strings, but you can provide a custom compare function.
Mastering these advanced array methods can significantly enhance your JavaScript programming skills, allowing you to write more efficient, readable, and maintainable code. Each method offers unique advantages for manipulating and processing arrays, from transforming data with map() and reduce() to filtering and searching with filter() and find(). Understanding their time and space complexities helps you choose the most appropriate method for your specific needs. By integrating these powerful tools into your development workflow, you’ll be well-equipped to tackle complex data transformations and optimizations with confidence. Happy coding! | delia_code | |

1,898,391 | DOM Selection with Custom Function | Objective: Create and use a custom function to select DOM elements similar to how jQuery's $ function... | 0 | 2024-06-24T04:50:30 | https://dev.to/__khojiakbar__/dom-selection-with-custom-function-199c | custom, dom, selection, javascript | **Objective:**
Create and use a custom function to select DOM elements similar to how jQuery's **$** function works.
**Explanation:**
We'll define a function named **$** that uses **document.querySelector** to select an element based on a CSS selector.
**Code Example:**
Here's the HTML and JavaScript needed to create and use the custom **$** function.
####**HTML:**
```
<!DOCTYPE html>
<html>
<head>
<title>DOM Selection Example</title>
</head>
<body>
<button id="submit-btn">Submit</button>
<div class="card">Card Content</div>
<input type="text" class="form" placeholder="Enter text">
<div class="space">Space Content</div>
<script src="script.js"></script>
</body>
</html>
```
####**JavaScript (script.js):**
```
// Define the custom $ function
function $(selector) {
return document.querySelector(selector);
}
// Select elements using the custom $ function
const submitBtn = $('#submit-btn'),
card = $('.card'),
formInput = $('.form'),
space = $('.space');
// Log the selected elements to the console
console.log(submitBtn); // Output: <button id="submit-btn">Submit</button>
console.log(card); // Output: <div class="card">Card Content</div>
console.log(formInput); // Output: <input type="text" class="form" placeholder="Enter text">
console.log(space); // Output: <div class="space">Space Content</div>
```
**Steps:**
**1. Define the Custom Function:**
Create a function named **$** that takes a selector as a parameter.
Use **document.querySelector** inside the function to return the selected element.
```
function $(selector) {
return document.querySelector(selector);
}
```
**2. Select Elements:**
Use the **$** function to select elements from the DOM.
Pass a CSS selector (e.g., **'#submit-btn'**, **'.card'**) as the argument to the **$** function.
```
const submitBtn = $('#submit-btn'),
card = $('.card'),
formInput = $('.form'),
space = $('.space');
```
####**3. Log the Selected Elements:**
Log the selected elements to the console to verify that they have been correctly selected.
```
console.log(submitBtn); // Output: <button id="submit-btn">Submit</button>
console.log(card); // Output: <div class="card">Card Content</div>
console.log(formInput); // Output: <input type="text" class="form" placeholder="Enter text">
console.log(space); // Output: <div class="space">Space Content</div>
```
By defining a custom **$** function, you can simplify the process of selecting DOM elements, making your code cleaner and more readable. This approach is especially useful if you are familiar with jQuery and want similar functionality in vanilla JavaScript.

Assets in your application are supplementary files that the browser requests after the initial chunk of HTML is loaded. These assets include CSS stylesheets, JavaScript files, images, videos, and more.
## What is the Asset Pipeline?
The asset pipeline provides a framework to handle the delivery of JavaScript and CSS assets.
When you create a new rails app using below command:
`rails new my-demo-app`
By default, you will get **sprockets-rails** for CSS and **importmap-rails** for JavaScript processing. You can find these gems in your Gemfile.
## Features of Asset Pipeline
- Adding **fingerprints** to the assets, so that the file is cached by the web browser and CDN.
For example, If your app has a stylesheet named navbar.css. It will insert a SHA256 fingerprint to that file like below.
`navbar-908e25f4bf641868d8683022a5b62f54.css`
You can invalidate the cache by altering this fingerprint, which happens automatically whenever you change the file contents.
- JavaScript processing using **import maps**.
- Concatenate all CSS files into one main **.css** file, which is then minified or compressed.
- It allows coding assets via a higher-level language for CSS.
## Import maps:
Import maps let you import JavaScript modules using logical names that map to versioned/digested files – directly from the browser.
**Enough of theory, let's dive into a simple example to see how it works all together**
Create one new rails app using the below commands, If not created already.
```
rails new my-demo-app
cd my-demo-app
rails s
```
Now in our new application, we are going to add bootstrap library.
Importmaps provide a way to pin JavaScript modules and load them in your application directly from a CDN or locally.
Adding bootstrap and popperjs using jspm cdn link.
`config/importmap.rb:`
```ruby
# Pin npm packages by running ./bin/importmap
pin "application"
pin "@hotwired/turbo-rails", to: "turbo.min.js"
pin "@hotwired/stimulus", to: "stimulus.min.js"
pin "@hotwired/stimulus-loading", to: "stimulus-loading.js"
pin_all_from "app/javascript/controllers", under: "controllers"
pin "bootstrap", to: "https://ga.jspm.io/npm:bootstrap@5.3.3/dist/js/bootstrap.esm.js"
pin "@popperjs/core", to: "https://ga.jspm.io/npm:@popperjs/core@2.11.8/lib/index.js"
```
We can add any npm packages using the below command as well, for eg.
`bin/importmap pin react react-dom`
vendor/javascript folder is the place where downloaded JS packages would be stored.
Then, import the package into your application.js as usual
`app/javascript/application.js:`
```ruby
// Configure your import map in config/importmap.rb. Read more: https://github.com/rails/importmap-rails
import "@hotwired/turbo-rails"
import "controllers"
import "bootstrap"
import "@popperjs/core"
```
To add bootstrap css into our app, copy all the code from [bootstrap cdn](https://ga.jspm.io/npm:bootstrap@5.3.3/dist/css/bootstrap.css) then create one new file **bootstrap.css** under **vendor/css** folder and paste in it. Now we need to add this to our asset load path.
`config/initializers/assets.rb:`
```ruby
# Be sure to restart your server when you modify this file.
# Version of your assets, change this if you want to expire all your assets.
Rails.application.config.assets.version = "1.0"
# Add additional assets to the asset load path.
Rails.application.config.assets.paths << Rails.root.join("vendor", "css")
# Precompile additional assets.
# application.js, application.css, and all non-JS/CSS in the app/assets
# folder are already added.
# Rails.application.config.assets.precompile += %w( admin.js admin.css )
```
Then rename application.css to application.scss and import bootstrap there like below.
`app/assets/stylesheets/application.scss:`
```ruby
/*
* This is a manifest file that'll be compiled into application.css, which will include all the files
* listed below.
*
* Any CSS (and SCSS, if configured) file within this directory, lib/assets/stylesheets, or any plugin's
* vendor/assets/stylesheets directory can be referenced here using a relative path.
*
* You're free to add application-wide styles to this file and they'll appear at the bottom of the
* compiled file so the styles you add here take precedence over styles defined in any other CSS
* files in this directory. Styles in this file should be added after the last require_* statement.
* It is generally better to create a new file per style scope.
*
*= require_tree .
*= require_self
*/
@import "bootstrap";
```
application.scss serves as the starting point where you import all the other stylesheets that make up our application's styles.
Sprockets on its own is not able to transpile the Sass into CSS. So we need a sass engine to transpile our sass to regular css. Add this gem in your Gemfile.
`gem 'dartsass-sprockets'`
then run `bundle install` command.
Now uncomment root path line your routes.
`config/routes.rb:`
```ruby
Rails.application.routes.draw do
# Define your application routes per the DSL in https://guides.rubyonrails.org/routing.html
# Reveal health status on /up that returns 200 if the app boots with no exceptions, otherwise 500.
# Can be used by load balancers and uptime monitors to verify that the app is live.
get "up" => "rails/health#show", as: :rails_health_check
# Defines the root path route ("/")
root "posts#index"
end
```
Under **app/controllers** folder, create one new file and paste the below code.
`posts_controller.rb:`
```ruby
class PostsController < ApplicationController
def index
end
end
```
Create one new view file at **app/views/posts** and paste the following html code in it:
`index.html.erb:`
```html
<nav class="navbar navbar-expand-lg navbar-light bg-light">
<div class="container-fluid">
<a class="navbar-brand" href="#">My Blog</a>
<button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarNav">
<ul class="navbar-nav ms-auto">
<li class="nav-item">
<a class="nav-link active" aria-current="page" href="#">Home</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">About</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Contact</a>
</li>
</ul>
</div>
</div>
</nav>
<div class="container mt-5">
<div class="row">
<div class="col-md-8">
<div class="blog-post mb-4">
<h2 class="blog-post-title">Blog Post Title 1</h2>
<p class="blog-post-meta">June 23, 2024 by <a href="#">Author</a></p>
<p>This is a paragraph from the first blog post. It contains some interesting content that readers might enjoy.</p>
<hr>
</div>
</div>
<div class="col-md-4">
<div class="p-4 mb-3 bg-light rounded">
<h4 class="fst-italic">About</h4>
<p class="mb-0">This is a simple blog page example using Bootstrap 5.3. Customize it as you like!</p>
</div>
</div>
</div>
</div>
<footer class="blog-footer text-center py-3 bg-light">
<p>Blog template built with <a href="https://getbootstrap.com/">Bootstrap</a>.</p>
</footer>
```
Create one new css file under **app/assets/stylesheets**. This is our custom stylesheet and paste the following css code.
`posts.css:`
```css
body {
font-family: Arial, sans-serif;
}
.navbar-brand {
font-weight: bold;
}
.blog-post-title {
color: #007bff;
margin-bottom: 0.5rem;
}
.blog-post-meta {
color: #6c757d;
margin-bottom: 1rem;
}
.blog-footer {
margin-top: 2rem;
border-top: 1px solid #e5e5e5;
}
.container {
max-width: 960px;
}
h4.fst-italic {
font-style: italic;
}
.p-4 {
padding: 1.5rem !important;
}
.p-4 .list-unstyled {
padding-left: 0;
list-style: none;
}
```
Finally, start our rails server using `rails s` to see things in action.
Now view your page source using Ctrl+U, all your application stylesheets concatenated into one big css file **application.css** and fingerprint is added as well.
Also our npm packages added successfully, see in the `<script type="importmap" data-turbo-track="reload"></script>` tags. The big advantage of this approach is it will eliminate the need for Webpack, yarn, node or any other part of the JavaScript toolchain.

Thanks for reading this post, will come back with another way of handling javascript in the rails app.

1,898,390 | AI-Powered Meal Planning Service with Twilio | This is a submission for the Twilio Challenge What I Built A meal planning service that... | 0 | 2024-06-24T04:45:07 | https://dev.to/bytrangle/ai-powered-meal-planning-service-with-twilio-396p | devchallenge, twiliochallenge, ai, twilio | *This is a submission for the [Twilio Challenge ](https://dev.to/challenges/twilio)*
## What I Built
<!-- Share an overview about your project. -->
A meal planning service that takes your meal plan request through WhatsApp messages, and send back your meal plan with recipes and all the important information: recipe url, image and source (the website that created the recipe). All of this achieved with the effortless magic of Twilio.
## Demo
[Source code for my app](https://glitch.com/edit/#!/magical-gold-wavelength)
*Send meal plan request to chatbot*
Receive a reply that says the meal plan has been sent to your given
email address.
Receive your meal plan in the inbox 🥣
Here's how you can try out this app.
<!-- Share a link to your app and include some screenshots here. -->
1. Send a WhatsApp message to number `+14155238886` with code `family-main`. This is Twilio's verified sandbox number.
2. Send a meal plan request in this format: `Your meal plan <your email>`. For example, this message has been tested successfully
`paleo vegan meal plan for 1 week <janedoe@gmail.com>`
Make sure that your message includes the greater than and less than symbols, and your email address is enclosed between them. You can omit "paleo vegan", or change to "x days", where x is a number less than 7, because Edamam only allows a certain number of recipes in each request. I'm only allocated 30 requests per day, so please try the above message once so that many people can enjoy this service.
3. You should get a success message. Wait for your meal plan to arrive in your inbox.
## Twilio and AI
<!-- Tell us how you leveraged Twilio’s capabilities with AI -->
Meal plan is complicated and time-consuming. Each person has a certain preferences and dietary need. Making a meal plan service that can please many different human beings is a near impossible task.
You can look up online meal planning services and most of them will send the same plan to every one, unless you are prepared to pay a premium price.
How about leverage AI to make meal plan more accessible? There's an API on the market that does just that: the [chatbot assistant](https://www.edamam.com/ai-chatbot-assistant/) from Edamam.
A diagram of the communication between WhatsApp user, this app and Edamam.
You don't see the name Twilio in the diagram, because it is the silent magician that does all the plumbing work. It allows me to process WhatsApp messages, respond to WhatsApp users and send helpful emails to them (a really big deal in the age of spams and frauds).
## Additional Prize Categories
*Twilio Times Two*: I used two Twilio APIs, one for WhatsApp and the other for Sendgrid.
*Impactful Innovators*: I believe this online meal planning service will free people from that dreadful question comes every weeknight: What's for dinner?
*Entertaining Endeavors*: On the other hand, this meal planning service is not production ready yet. It may suggest that you have ice cream or rosemary oil for dinner. Besides, many food websites branch out into housekeeping. Occasionally, you may get recipes for furniture polish, or mulled-cider sachets. The Meal Planning API from Edamam is unable to tell if a recipe is safe for human consumption or not. While we wait for the Edamam API to mature, let's treat this app like something lighthearted to lighten up your Sunday blues.
<!-- Does your submission qualify for any additional prize categories (Twilio Times Two, Impactful Innovators, Entertaining Endeavors)? Please list all that apply. -->
<!-- Team Submissions: Please pick one member to publish the submission and credit teammates by listing their DEV usernames directly in the body of the post. -->
<!-- Don't forget to add a cover image (if you want). -->
<!-- Thanks for participating! → | bytrangle |

## What I Built
In a world where mental health issues are becoming increasingly prevalent, our mission is to offer a safe, supportive, and non-judgmental space for individuals to share their struggles and receive immediate, compassionate guidance.
I would have liked to have had something like this on hand; some years ago. Also, the inspiration comes from the lyrics of this song: Logic - 1-800-273-8255
Harnessing the capabilities of Flask for our web framework, Twilio for seamless voice and SMS communication, and the advanced language models from OpenAI, I have created a tool that listens, understands, and responds with empathy and care.
**Features:**
1. Real-time voice Emotional Support: Users can reach out at any time by **calling** a dedicated number, where they are greeted by a responsive and empathetic voice ready to listen and help.
2. Supportive and Non-judgmental: Every interaction is crafted to be positive and supportive, creating a safe space for users to open up about their feelings.
3. Summarizing Advice: If a user decides to end the conversation, the chatbot provides a summarized advice via **SMS**, ensuring the user has a tangible reminder of the support received.
The system looks like this, I developed a microservice to handle the real time interaction and logic:
Inside de service, there is a graph of LLMs collaborating to produce a helpful system:
## Demo
[Code](https://github.com/Magody/TwilioLifeLineSupport/tree/main): https://github.com/Magody/TwilioLifeLineSupport/tree/main

{% embed https://drive.google.com/file/d/1BypmvvApB5jOd4fEONuuZum9oe4jl3xp/preview %}
If you want to try it, you probably want to call to: +16183270085. SMSs only are enabled geographically on: Canada, US, Mexico, Ecuador, Colombia, Chile. In https://console.twilio.com/us1/develop/sms/settings/geo-permissions
## Twilio and AI
**Twilio**
A. Voice Communication:
- Voice Calls
- Twilio Voice Response (TwiML): I utilized Twilio’s Voice Response capabilities to handle incoming calls.
B. SMS Communication:
- Sending Summaries: The system uses Twilio to send a summarized SMS containing the key points of the advice provided.
- Follow-Up Messages: Twilio’s SMS service is also used to send follow-up messages, providing additional resources or encouragement as needed.
**AI Integration**
A. Natural Language Processing (NLP):
- Understanding User Input: OpenAI’s language models enable the chatbot to accurately understand and process the user’s spoken words.
- Generating Compassionate Responses: The AI generates responses that are compassionate and empathetic.
B. Context-Aware Conversations:
- Maintaining Continuity: The AI keeps track of the conversation’s context by storing previous interactions in text files.
- Handling Crisis Situations: The AI can recognize when a user might be in crisis and responds with appropriate, comforting messages, encouraging the user to seek professional help if necessary.
## Additional Prize Categories
I think the projects is in the following categories
- Twilio Times Two: The project uses 2+ Twilio APIs (Call, SMS).
- Impactful Innovators: The project drives positive social impact. | magodyboy |

#The data structure, which is just a simple combination of key-value pairs, can be your key to solving majority coding questions!
I recently started with May Leetcode Challenge, and so far almost all the questions that I solved were solved using maps! And that's not it, maps can help you a lot in many tricky situations, especially during coding interviews.
When you are clueless about what to do? just give maps a try it is very likely that you will end up getting a solution. It won't be perfect, it won't be the most memory or time-efficient solution but, you'll get an answer.
This can be the point between getting an offer and not getting an offer!
---
During my preparation for Amazon Interview, I went through hundreds of interview experience, I did the same during my Google Interview also!
And a whooping, 60%-70% of the questions could be solved using some implementation of maps.
Not only this, but many senior developers, interviewers, and my friends also have suggested Maps as the goto solution when you don't have anywhere to go!
Some reasons why I feel Maps can be really helpful are:
You can access data in O(1) time complexity
Generally, in Tech Interviews there is more focus on minimizing time complexity compared to space. The map is the perfect candidate for this!
Ease of accessing data, as a key can be literally anything!
---
#What is a Map? Understanding it logically
A Map is a data structure in which we can store data in a format of key-value pairs.
To understand it more effectively let's take an example of a hypothetical world. In this imaginary world, every person is associated with a Unique Identification number.
The organization that runs this hypothetical world is very insecure and tracks every person with a GPS, by using the Unique ID (sorry this world doesn't have any concerns about your privacy).
So whenever they need to find any person, they just use the unique ID of that person and boom! They know where he/she is.
As this ID is unique for every person they can find any person within seconds and minimum efforts.
---
#How does it work?
Map stores all the entries in a key-value format in table
```
| KEY | VALUE |
-----------------------
| 1 | A |
-----------------------
| 2 | B |
-----------------------
| 456 | PQO |
-----------------------
| 789 | A |
```
Some rules that you must remember
1. A key can not be repeated again (It must be unique)
2. A value can be repeated many times
3. The data type of key must be consistent. For a particular map, all the keys should be either an INT or STRING, etc. (Python Dictionary can have multiple Datatypes as key values, but it is not suggested that you do that)
That is the structure of a map. Whenever a new entry comes it is appended to the table. If the key is already present you can modify the current value.
But, I guess you can do all this with normal arrays and vectors also. Then why do you need a map for this?
Let me ask you some questions.
Does array or vectors have the has_key or find or findKey method?
Can you access the values with an index which is a string, char, object, or struct?
NO! you can not do all this with simple arrays or vectors!
In arrays and vectors data is stored serially so the index range from 0 to n. But, in a map, we define the index so we can access the index in O(1). And the map provides us with a function that can tell us whether a particular exists or not!
This is the biggest USP of Maps!

#How to use it?
I'll tell you some basic and important functions related to maps in the C++ language. The key logic behind these functions remains the same only their name and usage changes, so don't worry if your favorite language is JAVA or Python. I'm sure you'll figure it out by using the documentations.

```
#include <bits/stdc++.h> //STL library (SUGGESTED)
OR
#include <map> //Only Map will be included
OR
#include <unordered_map> //Only Unordered Map will be included
```
2. Defining a Map
The unordered map also follow a similar process
```
map<int, string> peopleTracker;
/*
key: int
value: string:
name of map: peopleTracker
*/
```
3. Inserting data elements
Inserting Data is very similar to inserting data in an array or vector
```
peopleTracker[234] = "Mr John Doe";
/*
key: 234 and value:"Mr John Doe"
*/
```
4. Key Collisions
Here comes the tricky part, what is the entry already exits? Don't worry you'll simply override the previous Data
```
peopleTracker[234] = "Mr Dane John";
/*
value changed from "Mr John Doe" -> "Me Dane John"
*/
```
Now you want to check if there is an entry for some value or not. Here comes the find method!
```
if(peopleTracker.find(234) != peopleTracker.end())
cout << "Entry for 234 exits" << endl;
```
mapName.find method will return a pointer to the end of the map if there is no entry with matching key, else it will point to the entry with the corresponding key!
To learn more about maps and hash-table refer to this cheatsheet which was suggested by Trey Huffine.
---
Now enough of knowledge, its time to practice!
Try to solve these seven problems on Leetcode.
Not all problems can be solved using a map, but figuring out where to use the map is also a skill! So go give your brains some exercise and try to solve these questions!
I hope you'll understand where and how you can use maps and hash tables. With consistent practice, you'll be able to master this data structure.

Once again thank you for reading!
Happy Coding :)

1,898,382 | Ultimate Guide to Coding Anarchy | Intro Are you tired of writing boring, predictable code? Ready for a change? Well, buckle... | 0 | 2024-06-24T04:24:17 | https://dev.to/ibrahim_mohammed_47/ultimate-guide-to-coding-anarchy-12po | coding, programming, cleancode, javascript | ### Intro
Are you tired of writing boring, predictable code? Ready for a change? Well, buckle up! This guide provides you with 10 pieces of advice that will turn your codebase into a wild rollercoaster ride for anyone brave enough to maintain it! Warning: the advice in this article is sarcastic and should be reversed if you value your sanity (no shit, Sherlock).
### 1. Wet your code
Do you remember that smart code snippet that handles user authentication you copied from StackOverflow? I want you to copy/paste that snippet all over the project. Don't wrap it in a function that has a meaningful name that can be called whenever needed. Don't make your code [DRY](https://en.wikipedia.org/wiki/Don%27t_repeat_yourself). Why? The main benefit is whenever you find a bug in this snippet, you will go through a long and amusing journey of updating this snippet everywhere it's written. So Much Fun. It's also another way to force you and your team to revise your code from time to time. Your team will surely appreciate that.
### 2. Write smart one-liners
Have you earned respect in your team yet? No? Here is what you need to do, fill the codebase with smart one-liners that only smart people like you can understand.
Let me show you an example I like a lot, the following dumb simple easy-to-understand code wastes 3 lines from our precious javascript files:
```js
const obj = {};
If (x) { obj.x = x; }
If (y) { obj.y = y; }
```
Let's upgrade/optimize this code, for example, look at how compact and smart this alternative is:
```js
const obj = { …(x && { x }), …(y && { y}) };
```
After you adapt yourself to this cryptic coding style, you will get 70x respected within your team, thank me later.
### 3. Be inconsistent and unconventional
As an extension to the last advice, I want you to break out of conventions and liberate yourself from chains. Some people whine too much about how your code should be consistent and follow agreed-upon conventions. Those "clean coders" police are holding you back. Examples:
- Don't limit yourself to a single casing style within a project, make sure your functions have at least 2 casing styles like `camelCase` and `snake_case`.
- Also, your function names shouldn't follow the same naming style. That's too dull, some function names should be verbs, some should be nouns, and some should be adverbs!
- Always mix. Use a mix of callbacks, promises, async/await code. Use a mix of regular and arrow functions. Use mix classes and function constructors,...etc
Within your programming language community, you would usually find one or two coding [styling guides](https://google.github.io/styleguide/jsguide.html) to chain you, ignore those guides, and Just Be Creative!
### 4. Don't comment your code
A wise man once said: "*Good code does not need comments*". That's 100% true. Don't insult yourself by putting comments in your good code. Do you remember that 200-line critical function that handles user payments in the application? this one particularly shouldn't be commented, and all variables in it should have 2 or 3 character names. This function is too critical, so it should be optimized more than anything else!
### 5. Nest your code
Have you ever heard of "Code Aesthetics"? It's about making our code beautiful and amusing to look at. One way to achieve this is by making 3+ nesting levels of your code blocks. For example, don't write dull code like that:
```js
function checkDiscountEligibility(user) {
if (!user) return console.log('User data is missing')
if (!user.age) return console.log('User age is required')
if (user.age < 18) return console.log('User must be at least 18 years old')
if (!user.membership) return console.log('Membership status is required')
if (user.membership !== 'gold') return console.log('Only gold members are eligible for a discount')
applyDiscount(user)
}
```
Instead try writing a beautiful skewed pyramid shaped code like this:
```js
function checkDiscountEligibility(user) {
if (user) {
if (user.age) {
if (user.age >= 18) {
if (user.membership) {
if (user.membership === 'gold') {
applyDiscount(user)
} else {
console.log('Only gold members can get discount')
}
} else {
console.log('Membership status is required')
}
} else {
console.log('User must be at least 18 years old')
}
} else {
console.log('User age is required')
}
} else {
console.log('User data is missing')
}
}
```
### 6. Hardcode stuff
The more you Hardcode, the more Hardcore you are. Always hardcode configuration values, constants, and secrets(**especially secrets**) instead of grouping them in a config file or something as simple as a`.env` file. This will make your code comprehensive, have fewer dependencies, and also efficient(because no need to do additional lookups). You might ask what if we want to have different values for different environments? Simple do if conditions on the environment everywhere throughout the code. like this:
```js
let lifeSecret = ""
if (process.env.NODE_ENV === 'development'){
lifeSecret = "dev_blablabblalasec"
}
else if (process.env.NODE_ENV === 'production'){
lifeSecret = "prod_blablahardcoresec"
}
```
Hint: Don't follow [12 factor app rule](https://12factor.net/config) about organizing configs, those people are not efficient.
### 7. Don't handle errors
Errors are so overrated. Don't think too much about errors and handling them. Always focus on happy scenarios, because again, handling errors implicitly means that your code is error-prone, so please don't insult yourself. Some programming languages like Rust and Go deal with errors as first-class citizens to promote error handling explicitly. I'll give you examples but please this is only to show you how self in-confident those language developers are:
Go:
```go
result, err := divide(4, 2)
if err != nil {
fmt.Println("Error:", err)
} else {
fmt.Println("Result:", result)
}
```
Rust:
```rust
match read_file_to_string("example.txt") {
Ok(contents) => println!("File contents: {}", contents),
Err(e) => println!("Error reading file: {}", e)
}
```
### 8. Depend on global variables
Maximize the dependence of global variables in your code. Why pass stuff as function arguments when you can make your entire codebase a creative playground?
For example:
```js
const databaseConnection = require("database.js");
function fetchUserData(userId) {
databaseConnection.query(`SELECT * FROM users WHERE id = ${userId}`);
}
```
See how we completely ignore [dependency injection](https://medium.com/@omar.saibaa/dependency-injection-simply-45252e2457a8) and save an additional parameter by pulling `databaseConnection` from thin air into the function? Some people would argue that this has multiple drawbacks, like:
1. It makes the code less predictable
2. It makes this function untestable
3. 1. Preventing the application of the [Unit of Work](https://en.wikipedia.org/wiki/Unit_of_work) pattern to combine this function with others in a single transaction.
But who needs predictability when you can embrace spontaneous creativity? And testing? Who has time for testing in 2024? We are developers, not testers! I'm 100% sure those critics don't do testing themselves. And Unit of Work pattern? Sounds like extra work to me! Just... ignore them and enjoy the freedom of your creative coding!
### 9. Mutate objects by passing them to magic functions
This is one of my favorites. I find a lot of creative people doing it without even reading my article.
Look at this dull immutable version:
```js
const { originalDate } = require("./dates.js")
function addYear(date) {
const newDate = new Date(date.getTime()); // cloning the date object
newDate.setFullYear(newDate.getFullYear() + 1);
return newDate;
}
console.log(originalDate); // 2024-06-24T00:00:00.000Z
let updatedDate = addYear(originalDate);
console.log(originalDate); // 2024-06-24T00:00:00.000Z (still as is)
console.log(updatedDate); // 2025-06-24T00:00:00.000Z
```
Boring, right? Now, here's the "upgrade":
```js
const { originalDate } = require("./dates.js")
function addYear(date) {
date.setFullYear(date.getFullYear() + 1);
}
console.log(originalDate); // 2024-06-24T00:00:00.000Z
addYear(originalDate)
console.log(originalDate); // 2025-06-24T00:00:00.000Z (ta da!)
```
Isn't it thrilling? Now, anyone looking at `originalDate` will have no idea how and where it's value got mutated. Perfect!
### 10. Don't write secure code
A lot of paranoid devs worry too much about security, but this paranoia weakens your relationship with your app users. Learn to love your users, and you won't love them until you trust them completely by writing code like this:
```js
app.post('/register', async (req, res) => {
let userData = { role: "user", ...req.body };
await User.create(userData);
res.send('User created');
});
```
Now, imagine a request like this (but don't worry, your users would never do that of course):
```sh
`curl -X POST http://localhost:3000/register -H "Content-Type: application/json" -d '{"username": "hacker", "role": "admin"}'`
```
And this is what would be stored in our modern NoSQL store:
```
{ role: "admin", username: "hacker"}
```
See how effortless that is? Just merge everything from the request body into your sensitive data object. Who needs validation or sanitization? Trust your users—they always have your best interests at heart, right?
Always think good of your dear users. After all, what's the worst that could happen?
### Conclusion
Congratulations! You've now learned the art of writing code that's sure to keep your fellow developers entertained and on their toes. By following these anti-patterns, you can inject a bit of excitement into your workday and create a codebase that's as unpredictable as it is "creative." Remember, consistency, maintainability, and security are just suggestions. True creativity lies in embracing the chaos and trusting that your users and colleagues will understand your genius. Happy coding! | ibrahim_mohammed_47 |

This knowledge helps avoid unexpected behavior, especially when dealing with nested objects.
## Shallow Copy
A shallow copy duplicates the top level of an object but does not recursively copy nested objects. Instead, it retains references to the original nested objects. Here are some common methods for creating shallow copies: `Object.assign()` and the spread operator `{...object}`.
Example
In this example, changing the `fullName` in narutoCopy does not affect the original naruto object.
However, with nested objects, a shallow copy only copies the references:
In this case, both narutoDetails and narutoDetailsCopy have the same reference to the parent's object. Changing the father property in `narutoDetailsCopy` also changes it in `narutoDetails`.
## Deep Copy
A deep copy duplicates an object along with all the objects it references, recursively. The easiest way to achieve this in JavaScript is by using `JSON.parse(JSON.stringify(object))`. For more complex scenarios, libraries like lodash provide deep copy functions.
Example
In this example, `borutoCopy `is a completely independent copy of `boruto`. Changes to `borutoCopy `do not affect `boruto`. | rajusaha |

It’s been nine years since the groundbreaking ES6 standard was introduced, bringing a plethora of useful features to JavaScript. Among these, the new way of handling asynchronous operations through Promises stands out.
Initially, developers struggled with "callback hell," which was somewhat alleviated by the `.then/.catch` API. This evolved into the `async/await` syntax, making JavaScript more readable. However, even with `async/await`, the code could still be cumbersome:
```javascript
let result;
try {
result = await someWork();
} catch (err) {
// handle the error
}
// do something with the result
```
Two main issues persist:
1. The need to define a variable outside of the try/catch block.
2. Unnecessary indentation from the try/catch block.
To streamline this, inspired by Golang's error-handling, I created a simple function for JavaScript. This evolved into a set of utilities that I’ve now compiled into a package.
### One-Line Promise Handling with `to`
Instead of handling errors within try/catch blocks, you can use the `to` function from the `@mrspartak/promises` package:
```javascript
import { to } from '@mrspartak/promises'
const [error, result] = await to(somePromise)
```
#### Benefits:
- Infers proper return types.
- Does not throw errors.
- Allows flexible variable naming via array destructuring.
- Works on both back-end and front-end, supporting the `finally` API.
```javascript
let isLoading = true;
const [error, result] = await to(fetchData(), () => {
isLoading = false;
});
```
### Timeout Promise Execution
Sometimes, you need to ensure that a promise completes within a certain timeframe, such as network requests. The `timeout` function in our utility library ensures a promise resolves within a specified time:
```javascript
import { timeout } from "@mrspartak/promises"
import { api } from "./api"
const [error, user] = await timeout(api.getUser(), 1000, 'Timedout');
if (error) {
// handle the error
}
```
#### Benefits:
- Prevents hanging operations.
- Improves user experience by providing timely feedback.
### Delay the Execution
Introducing the `delay` function, a simple utility to pause code execution for a specified time. This is useful for rate limiting, retry mechanisms, or creating artificial delays for testing.
```javascript
import { delay, sleep } from "@mrspartak/promises"
import { parsePage } from "./parser"
for (let i = 0; i < 10; i++) {
const pageData = await parsePage(i);
await delay(1000);
}
```
#### Benefits:
- Enhances code reusability.
- Simplifies the introduction of delays.
- Adds flexibility for various scenarios like retry mechanisms and rate limiting.
### Defer the Execution
The `deferred` function provides a way to manually control the resolution or rejection of a promise, giving you full control over its lifecycle.
```javascript
import { deferred } from "@mrspartak/promises"
import { readStream } from "./stream"
const { promise, resolve, reject } = deferred<void>();
const stream = await readStream();
let data = '';
stream.on('data', (chunk) => {
data += chunk;
});
stream.on('end', () => {
resolve();
});
await promise;
console.log(data); // Data is ready
```
#### Benefits:
- Allows manual control over promise resolution/rejection.
- Provides flexibility for operations where results aren't immediately available.
### Retry the Execution
The `retry` function retries a promise-returning function a specified number of times, optionally with a delay between attempts.
```javascript
import { retry } from "@mrspartak/promises"
import { apiCall } from "./api"
const [error, result] = await retry(() => apiCall(), 3, { delay: 1000 });
if (error) {
// handle the error
}
```
#### Benefits:
- Retries failed operations, improving resilience.
- Can be customized with additional options like backoff algorithms and hooks.
### Measure the Duration of Execution
The `duration` function measures how long a promise takes to resolve or reject, providing insights into performance.
```javascript
import { duration } from "@mrspartak/promises"
import { migrate } from "./migrate"
const migratePromise = migrate();
const [error, result, duration] = await duration(migratePromise);
console.log(`Migration took ${duration}ms`);
```
#### Benefits:
- Helps identify performance bottlenecks.
- Facilitates optimization of asynchronous operations.
### Conclusion
By using these utility functions from the `@mrspartak/promises` package, you can handle asynchronous operations in JavaScript more efficiently and elegantly. These tools not only simplify your code but also improve its readability and maintainability, making it easier to manage complex asynchronous workflows. | srijan_karki |
1,898,329 | Design Patterns in Node.js | Node.js is a popular JavaScript runtime that allows developers to build scalable network applications... | 0 | 2024-06-24T04:09:12 | https://dev.to/vinay_madan/design-patterns-in-nodejs-1i66 | javascript, node, designpatterns | Node.js is a popular JavaScript runtime that allows developers to build scalable network applications using an event-driven, non-blocking I/O model. Like any sophisticated framework, Node.js applications can benefit from using proven design patterns to promote code reuse, maintainability and robustness. This article will provide an overview of some of the most useful design patterns for Node.js development
Introduction to Design Patterns
Design patterns are tried-and-true solutions to recurring problems that software developers encounter during their coding journey. They provide a structured approach to solving challenges and promote best practices in software architecture. By incorporating design patterns, developers can create more robust, maintainable, and extensible codebases.
### Why Design Patterns Matter in Node.js
Node.js, known for its non-blocking event-driven architecture, presents unique challenges and opportunities in software design. Applying design patterns tailored to Node.js can lead to more efficient and optimized applications. Let’s explore some key design patterns that are particularly valuable in the Node.js ecosystem:
### Singleton Pattern
The Singleton pattern ensures that a class has only one instance and provides a global point of access to it. In Node.js, where modules can be cached and shared across the application, using the Singleton pattern can help manage resources effectively. For instance, a database connection pool can be implemented as a singleton to prevent resource wastage.
```
class Database {
constructor() {
this.connection = null;
}
static getInstance() {
if (!Database.instance) {
Database.instance = new Database();
}
return Database.instance;
}
connect() {
// connect to database
this.connection = 'Connected';
}
}
const db1 = Database.getInstance();
const db2 = Database.getInstance();
console.log(db1 === db2); // true
db1.connect();
console.log(db1.connection); // 'Connected'
console.log(db2.connection); // 'Connected'
```
The key points are:
- The constructor is made private to prevent direct instantiation.
- The static method getInstance() creates an instance if it doesn't exist yet, and returns it. This ensures only one instance is created.
- The instances db1 and db2 refer to the same object.
- When db1 connects, db2 also gets the connection because they are the same object.
- This ensures there is only one database instance and prevents duplicating connections. The Singleton pattern is useful for situations where only one instance of a class should exist.
### Factory Pattern
The Factory pattern offers a way to create objects without specifying the exact class of object that will be created. In a Node.js context, this can simplify object creation, especially when dealing with asynchronous operations such as reading files or making API calls. By abstracting object creation, the Factory pattern enhances code readability and reusability.
```
class Car {
constructor(model, price) {
this.model = model;
this.price = price;
}
}
class CarFactory {
createCar(model) {
switch(model) {
case 'civic':
return new Car('Honda Civic', 20000);
case 'accord':
return new Car('Honda Accord', 25000);
case 'odyssey':
return new Car('Honda Odyssey', 30000);
default:
throw new Error('Unknown model');
}
}
}
const factory = new CarFactory();
const civic = factory.createCar('civic');
const accord = factory.createCar('accord');
console.log(civic.model); // Honda Civic
console.log(accord.model); // Honda Accord
```
The key points are:
- The CarFactory class handles object creation logic.
- The createCar() method returns a Car instance based on the model.
- The client code uses the factory instead of direct constructor calls.
- This abstracts away the object creation logic and allows easy extension of supported models. The Factory pattern is useful when there is complex object creation logic that should not be coupled to client code.
### Observer Pattern
Node.js’s event-driven nature aligns well with the Observer pattern. This pattern involves a subject that maintains a list of its dependents, called observers, and notifies them of any state changes. In the context of Node.js, this can be leveraged to build event-driven systems, such as real-time applications and chat applications.
```
class Subject {
constructor() {
this.observers = [];
}
subscribe(observer) {
this.observers.push(observer);
}
unsubscribe(observer) {
this.observers = this.observers.filter(o => o !== observer);
}
notify(data) {
this.observers.forEach(o => o.update(data));
}
}
class Observer {
constructor(name) {
this.name = name;
}
update(data) {
console.log(`${this.name} received ${data}`);
}
}
const subject = new Subject();
const observer1 = new Observer('Observer 1');
const observer2 = new Observer('Observer 2');
subject.subscribe(observer1);
subject.subscribe(observer2);
subject.notify('Hello World');
// Observer 1 received Hello World
// Observer 2 received Hello World
subject.unsubscribe(observer2);
subject.notify('Hello Again');
// Observer 1 received Hello Again
```
The key points are:
- The Subject maintains a list of observers.
- The observers subscribe and unsubscribe to the subject.
- When notify() is called, the subject updates all subscribed observers.
- This allows publishing updates to multiple objects without coupling the publisher to the subscribers. The Observer pattern is useful for event handling and asynchronous workflows.
### Middleware Pattern
Node.js’s middleware architecture is widely used for handling requests and responses in web applications. The Middleware pattern involves a chain of functions that process a request sequentially. Each function can modify the request or response before passing it to the next function in the chain. This pattern enhances modularity and allows developers to plug in various functionalities without tightly coupling them.
```
const express = require('express');
const app = express();
const logger = (req, res, next) => {
console.log('Logged');
next();
}
const authenticate = (req, res, next) => {
// authenticate user
next();
}
app.use(logger);
app.use(authenticate);
app.get('/', (req, res) => {
res.send('Hello World');
});
app.listen(3000);
```
The key points are:
- The middleware functions logger and authenticate wrap the route handler.
- They can execute logic before and after the route.
- The next() function passes control to the next middleware.
- app.use() mounts the middleware globally.
- This allows decomposing request handling into smaller reusable units. The middleware pattern is very common in Express and other Node.js frameworks for things like logging, authentication, etc.
Some other examples of middleware are body parsers, compression, rate limiting, and more. The pattern allows building the request pipeline in a modular fashion.
### Module Pattern
The module pattern is one of the most basic but fundamental patterns in Node.js. It allows you to organize your code into separate files or modules that encapsulate specific functionality.
```
// counter.js
let count = 0;
const increment = () => {
count++;
}
const decrement = () => {
count--;
}
const get = () => {
return count;
}
module.exports = {
increment,
decrement,
get
};
// app.js
const counter = require('./counter');
counter.increment();
counter.increment();
console.log(counter.get()); // 2
counter.decrement();
console.log(counter.get()); //
```
The key points are:
- The module counter.js exports some functions that operate on the private count variable.
- The functions encapsulate the logic and data within the module.
- app.js imports the module and uses the public API.
- This pattern provides data encapsulation and only exposes a public API. The module pattern is very common in Node.js to organize code into reusable and portable modules.
Some other examples are middleware modules, utility libraries, data access layers etc. The pattern helps manage dependencies and hide implementation details.
### Decorator Pattern
Decorators dynamically add new functionality to objects without affecting other instances. This is ideal for extending core modules in Node.
```
class Car {
constructor() {
this.price = 10000;
}
getPrice() {
return this.price;
}
}
class CarOptions {
constructor(car) {
this.car = car;
}
addGPS() {
this.car.price += 500;
}
addRims() {
this.car.price += 300;
}
}
const basicCar = new Car();
console.log(basicCar.getPrice()); // 10000
const carWithOptions = new CarOptions(basicCar);
carWithOptions.addGPS();
carWithOptions.addRims();
console.log(carWithOptions.car.getPrice()); // 10800
```
The key points are:
- CarOptions wraps the Car class and extends its behavior.
- Methods like addGPS() modify the state of the wrapped Car.
- The client has a decorated instance of Car with added functionality.
- This allows extending behavior dynamically at runtime. The Decorator pattern is useful for abstraction and not having to subclass just to add small features.
Some other examples are authenticated routes, logging wrappers, caching decorators etc. The pattern provides a flexible way to adhere to the Open/Closed principle in Node.js applications.
### Dependency Injection pattern
Dependency injection is a pattern where modules or classes receive dependencies from an external source rather than creating them internally. It helps with decoupling, testing, and reusability.
```
// service.js
class Service {
constructor(db, logger) {
this.db = db;
this.logger = logger;
}
async getUser(userId) {
const user = await this.db.findUserById(userId);
this.logger.log(`Fetched user ${user.name}`);
return user;
}
}
// app.js
const Database = require('./database');
const Logger = require('./logger');
const db = new Database();
const logger = new Logger();
const service = new Service(db, logger);
service.getUser(1);
```
The key points are:
- The Service class declares dependencies via the constructor.
- The calling code injects the actual dependencies like db and logger.
- This decouples Service from concrete dependencies.
Benefits:
Loose coupling between modules
Easier testing by mocking dependencies
Ability to swap implementations
The dependency injection pattern is commonly used with Node.js frameworks like NestJS. It enables better code organization and reusability.
Promise pattern
Promises are a pattern for asynchronous programming in Node.js. They represent the eventual result of an async operation. Here is a simple example:
```
const fetchData = new Promise((resolve, reject) => {
// async operation
const data = getDataFromDatabase();
if (data) {
resolve(data);
} else {
reject('Error fetching data');
}
});
fetchData
.then(data => {
// handle successful data
})
.catch(err => {
// handle error
});
```
The key aspects are:
- A Promise takes a callback with resolve and reject functions.
- The async operation is started inside the callback.
- resolve(data) returns the data on success.
- reject(error) returns the error on failure.
- Consumers use .then() and .catch() to get the result.
### Benefits:
**Avoid callback hell in async code**
Standardized way to handle async results
Ability to chain and compose promises
Promises are integral to modern Node.js development and enable writing clean asynchronous code. They power libraries like axios, core APIs like fs.promises, and more.
**Implementing Design Patterns**
Now that we’ve explored some key design patterns that align with Node.js’s strengths, let’s dive into how to implement them effectively:
1. Understanding Context
Before applying any design pattern, it’s crucial to understand the context of your application. Consider factors such as the application’s requirements, scalability needs, and the specific challenges you’re trying to address. Design patterns are not one-size-fits-all solutions; they should be tailored to fit the unique characteristics of your project.
2. Modularization
Node.js encourages modularization through its module system. When implementing design patterns, strive to keep modules small, focused, and single-responsibility. This promotes code reusability and maintainability, making it easier to swap out or enhance specific functionalities without affecting the entire application.
3. Asynchronous Patterns
Given Node.js’s asynchronous nature, it’s essential to choose design patterns that align with asynchronous programming paradigms. Patterns like the Observer pattern and the Middleware pattern naturally fit into the asynchronous environment, allowing developers to handle events and asynchronous operations seamlessly.
### Conclusion
Design patterns enable Node.js developers to write organized, flexible and robust code. Leveraging proven patterns like factories, decorators and singletons allows you to build large-scale applications that are easy to maintain and extend over time. Understanding how to apply design principles is key for mastering advanced Node development. | vinay_madan |

1,898,324 | Why CPU was not enough: Need for GPU in the picture of AI | The CPUs are the jack-of-all-trades but masters of none regarding parallel processing tasks. Normal... | 0 | 2024-06-24T04:04:06 | https://dev.to/nayanraj-adhikary/why-cpu-was-not-enough-need-for-gpu-in-the-picture-of-ai-3g09 | webdev, programming, cpu, gpu | The CPUs are the jack-of-all-trades but masters of none regarding parallel processing tasks.
Normal People: GPUs are generally used for video games. rty?
Developers: Do GPUs are generally used in ML? rty?
You all are correct. let's dive deep into GPU's
GPU's are used in many different use cases
1. **Graphics Rendering** :Rendering high-resolution graphics in video games, simulations, and visual effects. Because nobody wants to play a 3D game that looks like it’s from the ‘90s.
2. **Machine Learning** : Training large neural networks for deep learning applications. CPUs trying to handle this is like bringing a knife to a gunfight.
3. **Scientific Computing**: Performing large-scale simulations and computations in fields like physics, chemistry, and biology. CPU.
4. **Cryptocurrency Mining**: Solving complex cryptographic puzzles in mining cryptocurrencies like Bitcoin. CPUs would need a lifetime supply of energy drinks to keep up.
5. **Data Parallelism** : Processing large datasets where the same operation needs to be applied to many data points simultaneously. Think of it as the CPU trying to clone itself a thousand times – it's not going to happen.
I think a lot of questions when it comes to GPU coming into the picture from the perspective of AI/ML
1. What CPU was not able to handle?
2. How does CPU and GPU work hand in hand?
Before we go deep, let's see some key milestones
## Key milestones in GPU development
1. **1980s** : Early graphics accelerators were introduced to offload simple drawing tasks from the CPU.
2. **1990s** : The rise of 3D graphics in gaming and professional visualization led to the development of more advanced graphics hardware.
3. **2006** : NVIDIA introduced CUDA (Compute Unified Device Architecture), enabling GPUs to be used for general-purpose computing.
## Why CPU was not enough ?
The increasing demand for higher-quality graphics in video games and professional applications exposed the CPU's limitations in handling parallel processing tasks. CPUs are optimized for sequential serial processing, which is ideal for a wide range of general-purpose computing tasks. However, they struggle with the highly parallel nature of graphics rendering and the massive computational requirements of AI.
### CPU was not enough in
1. **Parallel Processing** : CPUs typically have a few cores optimized for sequential processing, whereas GPUs have thousands of smaller, efficient cores designed for parallel processing.
2. **Task Specialization** : CPUs are versatile and can handle a wide range of tasks, but this general-purpose nature limits their efficiency in specialized tasks like rendering graphics or performing large-scale matrix operations.
3. **Performance Bottlenecks** : The complex computations required for rendering high-quality graphics and processing large datasets created bottlenecks that CPUs could not efficiently overcome.
## GPU and CPU Coordination
Despite their differences, CPUs and GPUs are designed to work together, complementing each other’s strengths. In a typical computing task, the CPU handles the general-purpose processing and decision-making tasks, while the GPU handles the parallelizable tasks.
### How they coordinate:
- **Task Division** : The CPU offloads specific computationally intensive tasks to the GPU.
- **Data Transfer** : Data is transferred between the CPU and GPU through a high-speed interface such as PCIe (Peripheral Component Interconnect Express).
- **Synchronization** : Both units work in synchronization, with the CPU often preparing data and instructing the GPU on the operations needed, then processing the results.
## GPUs in AI and Large Language Models
In the realm of AI, GPUs have become indispensable. Training AI models, especially large language models (LLMs) like GPT-3 and beyond, involves processing vast amounts of data through complex computations. CPUs simply can't keep up with the demands.
### How GPUs are used in AI:
1. **Massive Parallelism** : AI training involves performing millions of matrix multiplications simultaneously. GPUs, with their thousands of cores, can handle these operations in parallel, significantly speeding up the training process.
2. **High Throughput** : For inference (running the trained model on new data), GPUs provide the high throughput necessary to process large amounts of data quickly.
3. **Energy Efficiency** : Despite their power, GPUs can be more energy-efficient than CPUs for specific tasks, making large-scale AI training more feasible.
4. **Optimized Libraries** : Libraries like TensorFlow and PyTorch are optimized for GPU acceleration, enabling researchers and engineers to leverage GPU power easily.
## Hardware-Based Accelerators:
1. **TPUs (Tensor Processing Units)** : Developed by Google, TPUs are custom-built application-specific integrated circuits (ASICs) designed to accelerate machine learning workloads. They are highly efficient for training and running AI models.
2. **FPGA (Field-Programmable Gate Arrays)** : These are reconfigurable hardware devices that can be programmed to perform specific computations efficiently. They offer a balance between flexibility and performance, suitable for specialized AI tasks.
These are some of them, this accelerators help us in training the model, which would take years for a CPU to do.
Python is recommended to have a lot of libraries and people use it a lot, internally they use the help of GPU when specified to be used.

1,897,523 | 🚀 Boost Your JavaScript Performance: Tips and Best Practices | JavaScript is a powerful language, but as your application grows, so do the performance challenges.... | 0 | 2024-06-24T04:00:00 | https://dev.to/parthchovatiya/boost-your-javascript-performance-tips-and-best-practices-114l | javascript, webdev, programming, tutorial | JavaScript is a powerful language, but as your application grows, so do the performance challenges. Ensuring your JavaScript code runs efficiently is crucial for delivering a smooth and responsive user experience. In this article, we’ll explore some essential tips and best practices to optimize your JavaScript performance.
## Minimize DOM Access
Manipulating the DOM is one of the most performance-intensive operations in JavaScript. Reducing the frequency and complexity of DOM access can significantly improve performance.
### Tip: Batch DOM Manipulations
Instead of modifying the DOM multiple times in a loop, accumulate changes and apply them in a single operation.
```
const fragment = document.createDocumentFragment();
for (let i = 0; i < 100; i++) {
const div = document.createElement('div');
div.textContent = `Item ${i}`;
fragment.appendChild(div);
}
document.body.appendChild(fragment);
```
## Optimize Loops
Loops are a fundamental part of JavaScript, but they can be optimized to run faster.
### Tip: Cache Length in Loops
When looping through arrays, cache the length to avoid recalculating it in each iteration.
```
const items = [/* array elements */];
for (let i = 0, len = items.length; i < len; i++) {
// Process items[i]
}
```
## Use Efficient Event Handling
Event listeners can degrade performance if not handled properly, especially in applications with many interactive elements.
### Tip: Event Delegation
Use event delegation to minimize the number of event listeners by taking advantage of event bubbling.
```
document.querySelector('#parentElement').addEventListener('click', (event) => {
if (event.target.matches('.childElement')) {
// Handle click event on childElement
}
});
```
## Debounce and Throttle
For events that fire rapidly (e.g., scroll, resize), use debounce and throttle techniques to limit the number of times your function is executed.
### Tip: Debounce
Execute a function only after a certain amount of time has passed since the last time it was invoked.
```
function debounce(func, delay) {
let timeoutId;
return function (...args) {
clearTimeout(timeoutId);
timeoutId = setTimeout(() => func.apply(this, args), delay);
};
}
const handleResize = debounce(() => {
console.log('Resized');
}, 300);
window.addEventListener('resize', handleResize);
```
### Tip: Throttle
Ensure a function is executed at most once in a specified period.
```
function throttle(func, limit) {
let lastFunc;
let lastRan;
return function (...args) {
const context = this;
if (!lastRan) {
func.apply(context, args);
lastRan = Date.now();
} else {
clearTimeout(lastFunc);
lastFunc = setTimeout(function () {
if ((Date.now() - lastRan) >= limit) {
func.apply(context, args);
lastRan = Date.now();
}
}, limit - (Date.now() - lastRan));
}
};
}
const handleScroll = throttle(() => {
console.log('Scrolled');
}, 300);
window.addEventListener('scroll', handleScroll);
```
## Optimize JSON Handling
Handling large JSON objects can be slow. Optimize your JSON parsing and stringifying.
### Tip: Stream JSON Parsing
For large JSON data, consider using streaming parsers like JSONStream.
```
const JSONStream = require('JSONStream');
const fs = require('fs');
fs.createReadStream('largeFile.json')
.pipe(JSONStream.parse('*'))
.on('data', (data) => {
console.log(data);
});
```
## Use Web Workers
For computationally heavy tasks, offload work to Web Workers to keep the main thread responsive.
```
const worker = new Worker('worker.js');
worker.postMessage('Start');
worker.onmessage = (event) => {
console.log('Message from Worker:', event.data);
};
// worker.js
self.onmessage = (event) => {
// Perform heavy computation
const result = performHeavyComputation(event.data);
self.postMessage(result);
};
function performHeavyComputation(data) {
// Simulate heavy computation
return data + ' processed';
}
```
## Lazy Load Images and Assets
Load images and other assets only when they are needed to reduce initial load time and save bandwidth.
### Tip: Intersection Observer
Use the Intersection Observer API to lazy load images as they come into the viewport.
```
const lazyImages = document.querySelectorAll('.lazy');
const imageObserver = new IntersectionObserver((entries, observer) => {
entries.forEach(entry => {
if (entry.isIntersecting) {
const img = entry.target;
img.src = img.dataset.src;
img.classList.remove('lazy');
observer.unobserve(img);
}
});
});
lazyImages.forEach(img => {
imageObserver.observe(img);
});
```
## Conclusion
Optimizing JavaScript performance is essential for creating fast and responsive web applications. By minimizing DOM access, optimizing loops, using efficient event handling, implementing debounce and throttle techniques, optimizing JSON handling, leveraging Web Workers, and lazy loading assets, you can significantly improve the performance of your JavaScript applications. Start implementing these tips and best practices today and notice the difference in your app’s performance.
Happy coding! 🚀

1,898,319 | Leetcode - 207. Course Schedule | U can read the question properly and give a try once before coming to the solution Incase you have... | 0 | 2024-06-24T03:53:58 | https://dev.to/rakeshreddy512/leetcode-207-course-schedule-3cdi | U can read the question properly and give a try once before coming to the solution
Incase you have tried and need help you can continue through the solution 🤗
Taking the **Example - 1 **
Input: numCourses = 2, prerequisites = [[1,0]]
so this tells us that we need to be completing 2 courses
and in order to complete course 1 we need to complete course 0
so this is possible as u can first complete course0 and then course 1
Taking the **Example - 2**
Input: numCourses = 2, prerequisites = [[1,0],[0,1]]
so here we want to complete the 2 courses course 1 and course 0 , and the prerequisites tell us that
prerequisite1 -> [1,0] in order to complete course 1 i need to complete course 0 ,
but the catch is to complete course 0. i need to complete course 1 , did u observe the loop here
so u can never complete the 2 courses so we need to return false
Now the problem is u might have got this but u didn't get how to put this idea in code form 😖
idea -> if a loop is found we return false otherwise true
to find if we have a loop we need to traverse the tree and see if we r visiting any node twice on exploration
we can explore the tree by graph traversal algorithms like DFS (Depth First Search) or BFS (Breadth First Search) . In this blog we are going with DFS
DFS is like we visit all the neighbour's of a node and move to the next node .
so in-order to traverse the tree , we need to have the tree 🌴.
**Example 3**
This code gives the adjacency list or like a tree
```javascript
const prerequisites = [[0,1],[0,2],[1,3],[1,4],[3,4]]
const preReqMap = {};
prerequisites.forEach((item)=>{
if(preReqMap.hasOwnProperty(item[0])){
preReqMap[item[0]] = [...preReqMap[item[0]] ,item[1]]
}else{
preReqMap[item[0]] = [item[1]]
}
})
console.log(preReqMap)
```
u now know which node is connected to which all neighbors now we need to traverse and while traversing if we found loop we return false
```javascript
//visitset storing which all we have visited
let visited = {}
const dfs = (node) =>{
if(visited[node]){
return false // if we have already visited it
}
if(preReqMap[node] !==undefined){
if(preReqMap[node].length == 0){
return true //if no neighbour's that means course can be completed as no prerequisite is needed
}
visited[node] = true;//marking it visited
//Exploring all neighbors of the node in recursive fashion
for(let val of preReqMap[node]){
if(!dfs(val)){
return false // retur
}
}
}
visited[node] = false;
preReqMap[node] = [];
return true
}
```
Finally
```javascript
for(let key in preReqMap){
if(!dfs(key)){
return false
}
}
return true
```

1,898,318 | Leetcode - 503. Next Greater Element II | key - in order to start in circular way -> generally we iterate starting from i=0 , j = (i+1) ... | 0 | 2024-06-24T03:52:50 | https://dev.to/rakeshreddy512/leetcode-503-next-greater-element-ii-2aoe | key - in order to start in circular way ->
generally we iterate starting from i=0 , j = (i+1) but since this is circular
we iterate i=0 , j = (i+1) % nums.length
in order to move to next element generally we do j++ or j = j +1
but since this is circular the next element of j will be (j+1) % nums.length
**Sample working **->
suppose when i goes to 3 , as j = i+1 ie 4 it crossed the end incase of nums = [1,2,1] , (i+1) % 4 ie 4 % 4 gives 0 , so it starts from index 0 instead of going to index 4
**Learning**
we can fill array of size n with -1 using new Array(n).fill(-1);
we can use break statements in for loops to exit out of loop
continue statement will skip one iteration
```javascript
/**
* @param {number[]} nums
* @return {number[]}
*/
var nextGreaterElements = function(nums) {
const n = nums.length;
const result = new Array(n).fill(-1)
for (let i = 0; i < nums.length; i++) {
let j = (i + 1) % nums.length; // Start from next index in a circular manner
while (j !== i) {
if (nums[j] > nums[i]) {
result[i] = nums[j];
break; // Break out of the loop once we find the next greater element
}
j = (j + 1) % nums.length; // Move to the next index in a circular manner
}
}
return result;
};

Unique Email Addresses | Lets quickly go into the solution for the unique email addresses problem we can see every email in... | 0 | 2024-06-24T03:51:41 | https://dev.to/rakeshreddy512/leetcode-929-unique-email-addresses-2joi | Lets quickly go into the solution for the unique email addresses problem
we can see every email in _localName + @ + domainName_ this form
```javascript
let localName = email.split('@')[0] ?? '';
const domainName = email.split('@')[1];
```
And the question tells if localName has + sign in it we need to ignore the rest of the characters after it , example "m.y+name@email.com" is equal to "m.y@email.com"
```javascript
if (localName.includes('+')) {
localName = localName.split('+')?.[0];
}
```
Also the question tells us that if we have . in email then it is considered as forwardable to the email , after replacing . (dot) with '' empty character
```javascript
if (localName.includes('.') || domainName.includes('.')) {
isForwardable = true;
localName = localName.replace(/\./g, '');
}
if (isForwardable) {
return localName + '@' + domainName; //returning email
} else {
return ''; //returning empty string if not forwardible
}
```
Complete code
```javascript
/**
* @param {string[]} emails
* @return {number}
*/
const convertEmail = email => {
let localName = email.split('@')[0] ?? '';
const domainName = email.split('@')[1];
let isForwardable = false;

It is equally opposite to Hacking that is a criminal activity one that hack and crack a system, make a virus and steal the data instead of secure it.
A guy named Bob Thomas wrote a program that able to move across the network by itself and leave a small trail. He named it creeper, It is not actively malicious program because it doesn’t damage the data. It just prints the messages “I’m the creeper. Catch me if you can.”
Later, Ray Tomlinson saw it and he liked it. He modifed the program and make it self-replicated. Then it was accepted as computer worm.
Another worm named Morris Worm appeared in 1986 and caused mayhem on the internet. It attacked more than thousands of systems on the internet. It is around 10% computer that connected to internet.
But the program creator didn’t foresee ths consequences. More importantly this act also let to the formation of the computer emergency response team as a non-profit research center for systemic issues that micht affect internet as a whole.
Nowadays viruses were deadlier more invasive and harder to controle. We have already experianced cyber incidens on a massive scale and 2021 isn’t close to over but these atacks are anough to prove that cyber security is a necessity for corporations and small businesses alike | fitrafep | |

1,898,307 | Computer Science Challenge - Structure Padding | This is a submission for DEV Computer Science Challenge v24.06.12: One Byte Explainer. ... | 0 | 2024-06-24T03:35:29 | https://dev.to/harshitads44217/computer-science-challenge-structure-padding-37ie | devchallenge, cschallenge, computerscience, beginners | *This is a submission for [DEV Computer Science Challenge v24.06.12: One Byte Explainer](https://dev.to/challenges/cs).*
## Explainer
Structure padding: Like neatly lining books on a shelf, compilers add empty bytes (padding) between struct members for faster processor access. This can make structs larger than expected!
## Additional Context
Consider this code:-
```c++
#include <iostream>
struct Data {
char c; // 1 byte
int i; // 4 bytes (assuming 32-bit system)
};
int main() {
std::cout << sizeof(Data) << std::endl; // Might be > 5!
}
```
Explanation:
- This code defines a Data struct with a char and an int.
- Similar to the previous example, we use `sizeof(Data)` to print the struct size. Here, padding might occur to ensure the int aligns with its preferred boundary (often 4 bytes on 32-bit systems).
- The expected size would be 1 (char) + 4 (int) = 5 bytes. However, the actual size might be greater due to padding.
- If you ask me, then it will be 8 bytes, since we are assuming a 32-bit system that will read the memory in the chunks of 4 bytes. This does not allow other variables to take the left 3 bytes (8-5) space. Hence 8 bytes will get occupied by the object of struct `Data` for faster processor access.
**Note:**
The exact amount of padding can vary depending on the compiler and target architecture.

1,898,305 | How to Build a Travel Agent with OpenAI API | Introduction Building an AI Agent has never been easier, thanks to the OpenAI API. In this... | 0 | 2024-06-24T03:34:31 | https://dev.to/jackyxbb/how-to-build-a-travel-agent-with-openai-api-2hoj | openai, ai, agent | ## Introduction
Building an AI Agent has never been easier, thanks to the OpenAI API. In this guide, we'll show you how to create your own AI agent to plan trips and provide travel tips. This step-by-step tutorial will help you build an AI-driven travel agent quickly. If you're wondering how to build an AI from scratch, this guide will walk you through the process. Let's get started!
## Who is this for?
This tutorial is intended for developers with basic knowledge of JavaScript and React who want to integrate OpenAI's capabilities into their applications to create intelligent, conversational agents.
## What will be covered?
1. React useEffect and useState Hooks
2. How to access weather API through OpenAI
3. Implementing weather, flight, and hotel data fetching using OpenAI.
***You can find the complete project code on [GitHub](https://github.com/jacky-xbb/travel-agent).***
## Step-by-Step Guide
### **1. Initialize the Project with Vite**
Create a new Vite project:
```bash
npm create vite@latest travel-agent -- --template react
cd travel-agent
```
### 2. Configure Environment Variables
Create a `.env` file in the root of your project and add your API keys:
```bash
VITE_OPENAI_API_KEY=your-openai-api-key
VITE_OPENAI_BASE_URL=https://api.openai.com/v1
VITE_WEATHER_API_KEY=your-openweathermap-api-key
```
### 3. **Install Necessary Dependencies**
Install dependencies for TailwindCSS, React Router, DatePicker, and other utilities:
```bash
npm install tailwindcss postcss autoprefixer react-router-dom react-datepicker openai
```
### 4. **Set Up TailwindCSS**
Initialize TailwindCSS:
```bash
npx tailwindcss init -p
```
Configure `tailwind.config.js`:
```
module.exports = {
content: [
"./index.html",
"./src/**/*.{js,ts,jsx,tsx}",
],
theme: {
extend: {},
},
plugins: [],
}
```
Add Tailwind directives to `src/index.css`:
```css
@tailwind base;
@tailwind components;
@tailwind utilities;
```
### 5. **Project Directory Structure**
Organize your project files as follows:
```
src/
├── components/
│ └── TravellerCounter.jsx
├── pages/
│ ├── Plan.jsx
│ └── Suggestion.jsx
├── utils/
│ ├── openai.js
│ ├── tools.js
│ └── weather.js
├── App.jsx
├── main.jsx
└── index.css
```
### 6. **TravellerCounter Component**
**src/components/TravellerCounter.jsx**
```jsx
import React from 'react';
import PropTypes from 'prop-types';
function TravellerCounter({ count, setCount }) {
// Function to increment the traveler count
const increment = () => setCount(count + 1);
// Function to decrement the traveler count, ensuring it doesn't go below 1
const decrement = () => setCount(count > 1 ? count - 1 : 1);
return (
<div className="max-w-xs mb-4">
<label htmlFor="quantity-input" className="block mb-2 text-sm font-medium text-gray-900">Number of Travellers</label>
<div className="relative flex items-center max-w-[8rem]">
<button
type="button"
id="decrement-button"
onClick={decrement}
className="bg-gray-100 hover:bg-gray-200 border border-gray-300 rounded-s-lg p-3 h-11">
<svg className="w-3 h-3 text-gray-900" aria-hidden="true" viewBox="0 0 18 2">
<path stroke="currentColor" strokeLinecap="round" strokeLinejoin="round" strokeWidth="2" d="M1 1h16" />
</svg>
</button>
<div className="bg-gray-50 border-x-0 border-gray-300 h-11 text-center text-gray-900 text-sm w-full py-2.5">{count}</div>
<button
type="button"
onClick={increment}
id="increment-button"
className="bg-gray-100 hover:bg-gray-200 border border-gray-300 rounded-e-lg p-3 h-11">
<svg className="w-3 h-3 text-gray-900" aria-hidden="true" viewBox="0 0 18 18">
<path stroke="currentColor" strokeLinecap="round" strokeLinejoin="round" strokeWidth="2" d="M9 1v16M1 9h16" />
</svg>
</button>
</div>
</div>
);
}
TravellerCounter.propTypes = {
count: PropTypes.number.isRequired, // Ensure count is a required number
setCount: PropTypes.func.isRequired, // Ensure setCount is a required function
};
export default TravellerCounter;
```
This component renders a label and buttons to increment or decrement the traveler count. The decrement button ensures the count doesn't go below 1. The buttons use SVGs to represent plus and minus symbols. The component also uses PropTypes to enforce the types of its props.
### 7. **Plan Page**
**src/pages/Plan.jsx**
```jsx
import React, { useState } from 'react';
import { useNavigate } from 'react-router-dom';
import DatePicker from 'react-datepicker';
import 'react-datepicker/dist/react-datepicker.css';
import TravellerCounter from '../components/TravellerCounter';
function Plan() {
const navigate = useNavigate();
const [flyingFrom, setFlyingFrom] = useState('Shanghai');
const [flyingTo, setFlyingTo] = useState('Tokyo');
const [fromDate, setFromDate] = useState(new Date());
const [toDate, setToDate] = useState(new Date(new Date().setDate(new Date().getDate() + 4)));
const [budget, setBudget] = useState(1000);
const [travelers, setTravelers] = useState(1);
const [errors, setErrors] = useState({ flyingFrom: '', flyingTo: '', fromDate: '', toDate: '', budget: '' });
// Validate city name using a regex that only allows letters and spaces
const validateCity = (city) => /^[a-zA-Z\\s]+$/.test(city);
// Validate budget to ensure it's a positive number
const validateBudget = (budget) => !isNaN(budget) && budget > 0;
// Handle form submission
const handleSubmit = (e) => {
e.preventDefault();
const isValidFlyingFrom = validateCity(flyingFrom);
const isValidFlyingTo = validateCity(flyingTo);
const isValidBudget = validateBudget(budget);
const isValidDates = fromDate <= toDate;
if (isValidFlyingFrom && isValidFlyingTo && isValidBudget && isValidDates) {
// Navigate to the suggestion page with the form data
navigate('/suggestion', {
state: { flyingFrom, flyingTo, fromDate, toDate, budget, travelers }
});
} else {
// Set error messages for invalid inputs
setErrors({
flyingFrom: isValidFlyingFrom ? '' : 'Invalid city name',
flyingTo: isValidFlyingTo ? '' : 'Invalid city name',
fromDate: isValidDates ? '' : 'From Date should be less than or equal to To Date',
toDate: isValidDates ? '' : 'To Date should be greater than or equal to From Date',
budget: isValidBudget ? '' : 'Invalid budget amount',
});
}
};
return (
<div className="flex flex-col items-center py-8 mx-auto max-w-md">
<h1 className="mb-4 text-2xl font-bold text-center">Travel Agent</h1>
<form className="w-full" onSubmit={handleSubmit} noValidate>

);
}
export default Plan;
```
This code defines the `Plan` component, which includes:
- State hooks to manage input values (`flyingFrom`, `flyingTo`, `fromDate`, `toDate`, `budget`, and `travelers`).
- Validation functions to ensure that city names are valid and budgets are positive numbers.
- An `handleSubmit` function that validates the form inputs and navigates to the `Suggestion` page with the form data if all inputs are valid. If not, it sets appropriate error messages.
- The JSX structure of the form, including input fields and a `TravellerCounter` component for managing the number of travelers.
### 8. **Suggestion Page**
**src/pages/Suggestion.jsx**

The `Suggestion` component:
- Uses the `useLocation` hook from `react-router-dom` to access the state passed from the `Plan` page.
- Initializes state variables to store weather, flight, and hotel information, as well as loading states for each.
- Uses the `useEffect` hook to fetch weather, flight, and hotel information when the component mounts or when any dependency changes.
- Fetches data using the OpenAI API and sets the state with the fetched data.
- Renders the trip details, weather, flight, and hotel information. If the data is still being fetched, it shows a loading message.
*Please refer to the [documentation](https://github.com/openai/openai-node/tree/master?tab=readme-ov-file#automated-function-calls) for detailed usage instructions for the runTools feature.*
### 9. **OpenAI Client Configuration**
**src/utils/openai.js**
```jsx
import OpenAI from "openai";
const openAIApiKey = import.meta.env.VITE_OPENAI_API_KEY; // Import OpenAI API key from environment variables
const openAIUrl = import.meta.env.VITE_OPENAI_BASE_URL; // Import OpenAI base URL from environment variables
export const client = new OpenAI({
apiKey: openAIApiKey,
baseURL: openAIUrl,
dangerouslyAllowBrowser: true,
});
```
This code configures the OpenAI client using the API key and base URL from environment variables. The client is exported for use in other parts of the application.
### 10. **Tools Configuration**
**src/utils/tools.js**
```jsx
import { getWeather } from './weather';
export const tools = [
{
type: 'function',
function: {
function: getWeather,
parse: JSON.parse,
parameters: {
type: 'object',
properties: {
city: { type: 'string' },
},
required: ['city']
},
},
}
];
```
This code defines a tools configuration that includes a weather-fetching function. The `getWeather` function is imported from the `weather.js` module. The tool configuration specifies the expected input parameters and how to parse them.
### 11. **Weather Utility**
**src/utils/weather.js**
*You need to create an API Key on the [openweathermap](https://openweathermap.org/api).*
```jsx
const weatherAIApiKey = import.meta.env.VITE_WEATHER_API_KEY; // Import weather API key from environment variables
export async function getWeather({ city }) {
try {
const endpoint = `http://api.openweathermap.org/data/2.5/forecast?q=${city}&appid=${weatherAIApiKey}&units=
metric`;
const response = await fetch(endpoint);
if (!response.ok) {
throw new Error(`HTTP error! status: ${response.status} ${response.statusText}`);
}
const data = await response.json();
const weatherReport = displayWeather(data);
return { report: weatherReport };
} catch (error) {
console.error('Error fetching weather data:', error.message);
throw error;
}
}
export function displayWeather(data) {
const targetTime = '12:00:00'; // Specific time to extract the weather data
const dailyData = data.list.filter(entry => entry.dt_txt.includes(targetTime));
return dailyData.slice(0, 5).map(entry => {
const date = entry.dt_txt.split(' ')[0];
const description = entry.weather[0].description;
const temp_min = entry.main.temp_min;
const temp_max = entry.main.temp_max;
return `Date: ${date}, Weather: ${description}, Temperature: Min ${temp_min}°C, Max ${temp_max}°C`;
}).join('\\n');
}
```
This module defines two functions: `getWeather` and `displayWeather`.
- `getWeather`: Fetches weather data from the OpenWeatherMap API using the provided city name. It processes the API response and extracts relevant weather information.
- `displayWeather`: Filters and formats the weather data for a specific time of the day (12:00:00) and returns a string with weather details for the next five days.
### 12. **Running the Application**

# Supercharging Modern Applications with AWS AppSync
In today's digital landscape, users expect real-time, responsive, and personalized experiences across all their devices. Building applications that deliver this can be complex and time-consuming, requiring developers to manage data synchronization, offline capabilities, and intricate backend infrastructure. This is where AWS AppSync comes in, providing a fully managed serverless GraphQL service that simplifies application development and empowers developers to build engaging and scalable applications with ease.
### What is AWS AppSync?
AWS AppSync is a fully managed service that simplifies the development of GraphQL APIs by providing:
- **Unified Data Access:** AppSync acts as a single endpoint for querying data from various sources, including databases (Amazon DynamoDB, Amazon Aurora, etc.), APIs, and even serverless functions (AWS Lambda).
- **Real-time and Offline Capabilities:** Build applications with real-time data updates and offline functionality, ensuring seamless user experiences even with intermittent connectivity.
- **Secure and Scalable:** Leverage AWS's robust security features and AppSync's inherent scalability to build reliable and high-performing applications.
- **Simplified Development:** Focus on building application logic instead of managing infrastructure complexities. AppSync handles schema definition, resolvers (functions connecting queries to data sources), and API gateway configurations.
### Delving into AppSync: Core Components
AppSync's power lies in its well-defined architecture, consisting of:
1. **Schema Definition:** Defines the types of data your API will handle and the operations (queries, mutations, subscriptions) allowed on them. This schema, written in GraphQL Schema Definition Language (SDL), acts as a contract between your client and server.
```graphql
type Todo {
id: ID!
name: String!
completed: Boolean!
}
type Query {
getTodos: [Todo]
getTodoById(id: ID!): Todo
}
type Mutation {
createTodo(name: String!): Todo
updateTodo(id: ID!, completed: Boolean!): Todo
}
```
2. **Resolvers:** Act as the bridge between the schema and your data sources. Written as functions (e.g., using Node.js or Python in AWS Lambda), resolvers fetch or modify data in response to client requests. They parse the GraphQL request, interact with the backend, and format the response back according to the schema.
3. **Data Sources:** AppSync supports a variety of data sources:
- **Amazon DynamoDB:** A NoSQL database offering low latency and high scalability, well-suited for real-time applications.
- **Amazon Aurora:** A MySQL and PostgreSQL-compatible relational database, offering the familiarity of SQL within AppSync.
- **AWS Lambda:** Enables integration with virtually any data source or API using custom logic within serverless functions.
- **Amazon Elasticsearch Service:** A managed Elasticsearch service for powerful search and analytics capabilities within your AppSync API.
- **HTTP:** Integrate with existing REST APIs or any publicly accessible endpoint.
4. **API:** Once your schema, resolvers, and data sources are configured, AppSync exposes your GraphQL API as a secure endpoint, ready to be consumed by your application clients.
### Real-World Use Cases: Beyond the Basics
Here's how AWS AppSync addresses specific use case scenarios:
**1. Real-time Collaboration:** Imagine building a collaborative document editing platform. AppSync's real-time subscriptions allow multiple users to see changes made by others instantly, enhancing the collaborative experience.
* **Implementation:** Use AppSync subscriptions triggered by mutations (data updates). When a user edits the document, the change is pushed to the backend (e.g., DynamoDB). AppSync then notifies all subscribed clients about this update in real-time, enabling them to reflect the changes instantly.
**2. Mobile-First Applications with Offline Support:** Consider a field data collection app used in areas with unreliable internet. AppSync enables offline data synchronization.
* **Implementation:** Integrate AppSync with a local data store on the device (e.g., SQLite). When online, the app synchronizes with the backend. While offline, changes are stored locally and automatically synchronized when connectivity is restored, ensuring data integrity and a seamless offline experience.
**3. Microservice Integration:** In a microservice architecture, retrieving data from multiple services can be cumbersome. AppSync acts as an API gateway, abstracting this complexity.
* **Implementation:** Define a unified GraphQL schema in AppSync representing data from different microservices. Resolvers would then interact with each service (potentially using AWS API Gateway or directly) and aggregate data into a single response, presenting a simplified view for client applications.
**4. Personalized User Experiences:** Delivering tailored content to users enhances engagement. AppSync, combined with analytics data, powers personalized experiences.
* **Implementation:** Store user preferences and behavior data (e.g., purchase history, browsing patterns) in a database. Leverage AppSync resolvers to dynamically fetch this data and tailor API responses. For example, a "Recommended Products" query could return different results based on user-specific data.
**5. Internet of Things (IoT) Data Management:** Handling real-time data streams from IoT devices is crucial for monitoring and analysis.
* **Implementation:** Use AWS IoT Core to ingest data from devices. Configure AppSync subscriptions to receive real-time updates from IoT Core. Build dashboards or visualizations within your application that react instantly to device data changes. For historical analysis, store the data in a time-series database like Amazon Timestream and query it via AppSync.
### Alternatives to Consider: Expanding the Landscape
While AWS AppSync offers a robust solution, consider these alternatives:
- **Hasura:** Open-source GraphQL engine that connects to your databases and instantly provides a GraphQL API. Focuses on instant setup and ease of use, ideal for rapid prototyping.
- **GraphCMS:** A headless CMS with a built-in GraphQL API, suitable for content-heavy applications requiring flexible content management.
- **Building a Custom GraphQL Server:** Provides maximum flexibility and control, but comes with increased development and maintenance overhead.
### Conclusion: Empowering the Future of Application Development
AWS AppSync empowers developers to build modern, data-driven applications with real-time capabilities, offline functionality, and streamlined data access. Its serverless nature simplifies infrastructure management, enabling you to focus on delivering exceptional user experiences. As we move towards increasingly interconnected and data-rich applications, tools like AppSync will be essential for building the next generation of software.
### Advanced Use Case: Architecting a Real-Time Logistics Platform with AppSync and AWS Services
**The Challenge:** Building a logistics platform that provides real-time tracking of shipments, dynamic route optimization based on traffic conditions and delivery windows, and seamless communication between drivers, dispatchers, and customers.

- **AWS IoT Core:** Ingest data streams from devices, perform initial data processing, and trigger downstream services.
- **AWS Lambda:** Implement custom logic for advanced data transformation and enrichment (e.g., geocoding addresses, calculating estimated arrival times).
- **Amazon Kinesis Data Streams:** Handle high-throughput real-time data streams from IoT devices for tasks like anomaly detection or predictive maintenance.
2. **Real-Time Data Management and Synchronization:**
- **Amazon DynamoDB:** Store shipment details, driver information, customer orders, and real-time location updates for low-latency access.
- **AWS AppSync:**
- Expose a GraphQL API for client applications to interact with real-time data.
- Use subscriptions to push location updates to dispatchers and customers, providing live tracking on maps.
- Allow drivers to receive optimized routes based on real-time traffic conditions (pulled from a service like Google Maps API via Lambda resolvers).
3. **Communication and Collaboration:**
- **Amazon Chime SDK:** Embed real-time chat and video conferencing features into the platform, allowing drivers to communicate with dispatchers and customers directly.
- **AppSync Mutations:** Update shipment statuses in real-time (e.g., "Out for Delivery," "Delivered"), triggering notifications to relevant parties.
4. **Data Analytics and Insights:**
- **Amazon Elasticsearch Service:** Analyze historical location and sensor data for route optimization, driver performance evaluation, and predictive maintenance.
- **Amazon QuickSight:** Build dashboards and visualizations to track key metrics and gain insights into operational efficiency.
**Benefits:**

* `sudo mkfs -t ext4 -N 2000000 /dev/sdb1` - This will manually set the number of inodes to 2,000,000
## Mount disk
* `mount` - Shows what is mounted
* `mkdir /mnt/mydrive`
* `mount -t ext4 /dev/sdb1 /mnt/mydrive`
## Get disk's UUID
`ls -al /dev/disk/by-uuid/`
or
`blkid`
## Mount at boot
Add the following line to your `/etc/fstab` file adjusting the UUID to your device's id and the directory to where you want to mount:
`UUID=811d3de0-ca6b-4b61-9445-af2e306d9999 /mnt/mydrive ext4 defaults 0 0`
`mount -a` - remounts filesystems from `/etc/fstab`

<h2 class="wp-block-heading">What is a Sales Tracking System?</h2>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p>A sales tracking system is a tool that monitors and analyzes your entire sales process. It's like a digital dashboard for your sales team, capturing vital data at every stage - from initial leads to closed deals and follow-ups.</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>This system does more than just count sales. It provides valuable insights into:</p>
<!-- /wp:paragraph -->
<!-- wp:list {"ordered":true} -->
<ol><!-- wp:list-item -->
<li>Who your potential customers are</li>
<!-- /wp:list-item -->
<!-- wp:list-item -->
<li>How they interact with your business</li>
<!-- /wp:list-item -->
<!-- wp:list-item -->
<li>Which products or services are selling best</li>
<!-- /wp:list-item -->
<!-- wp:list-item -->
<li>How your sales team is performing</li>
<!-- /wp:list-item --></ol>
<!-- /wp:list -->
<!-- wp:paragraph -->
<p>By collecting and organizing this data, a sales tracking system helps you spot trends, forecast future sales, and identify areas where you can improve your sales strategy.</p>

<h2 class="wp-block-heading">How to Build a Sales Tracking System</h2>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p>Building a robust sales tracking system doesn't have to be complicated. Here's a step-by-step approach:</p>
<!-- /wp:paragraph -->
<!-- wp:list {"ordered":true} -->
<ol><!-- wp:list-item -->
<li><strong>Use a Centralized System</strong>: Ensure all sales data is captured in a single, centralized system to avoid data silos and ensure data consistency.</li>
<!-- /wp:list-item -->
<!-- wp:list-item -->
<li><strong>Automate Data Entry</strong>: Minimize manual data entry by automating the capture of sales data from various sources like directly from your website.</li>
<!-- /wp:list-item -->
<!-- wp:list-item -->
<li><strong>Track Key Metrics</strong>: Monitor important sales metrics, such as conversion rates, sales cycle length, average deal size, and sales pipeline stages.</li>
<!-- /wp:list-item -->
<!-- wp:list-item -->
<li><strong>Visualize Data</strong>: Use charts, dashboards, and reports to visualize sales data and identify trends and patterns easily.</li>
<!-- /wp:list-item --></ol>
<!-- /wp:list -->

<h2 class="wp-block-heading">How Do You Track Sales Data?</h2>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p>Tracking sales data involves several steps, from capturing data to analyzing it for insights. Here’s a step-by-step guide to building a sales tracking system using Five:</p>
<!-- /wp:paragraph -->
<!-- wp:heading {"level":3} -->
<h3 class="wp-block-heading">Building a Custom Sales Tracking System: Prerequisites</h3>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p>This guide will walk you through the process of building a custom sales tracking system using Five (a rapid application builder). By the end of this tutorial, you'll learn how to develop an external web application that tracks your sales activities. Here’s what you'll need to get started:</p>
<!-- /wp:paragraph -->
<!-- wp:list {"ordered":true} -->
<ol><!-- wp:list-item -->
<li><strong>Five Installation</strong>: Get free access to Five which allows you to build custom online database applications. To get started, sign up <a href="https://five.co/get-started/">here</a>.</li>
<!-- /wp:list-item -->
<!-- wp:list-item -->
<li><strong>Sales Data Source</strong>: Ensure you have access to your sales data, whether it's from an existing CRM, e-commerce platform, or other sales-related tools. <strong>Today we'll be connecting to Shopify.</strong></li>
<!-- /wp:list-item --></ol>
<!-- /wp:list -->
<!-- wp:paragraph -->
<p>Once you are equipped with Five, you will connect it to your sales data source and treat it as a data source for your web app. This enables you to build forms, <a href="https://five.co/blog/how-to-build-charts-using-the-chart-wizard/">charts, dashboards</a>, and <a href="https://five.co/blog/generate-mysql-pdf-report/">reports</a> on top of the data.</p>

<!-- wp:heading -->
<h2 class="wp-block-heading">Step 1: Configuring Your Sales Data Source</h2>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p>To configure your sales data source, follow these steps:</p>
<!-- /wp:paragraph -->
<!-- wp:list {"ordered":true} -->
<ol><!-- wp:list-item -->
<li><strong>Log into Your Sales Platform</strong>: Log into your existing sales platform (such as your CRM or e-commerce platform) and identify the API or data export options available.</li>
<!-- /wp:list-item -->
<!-- wp:list-item -->
<li><strong>Create an API Connection</strong>: If your platform provides API access, create a connection to allow Five to interact with your sales data. Configure the API access scopes for the data you wish to track, such as leads, opportunities, sales transactions, and customer interactions.</li>
<!-- /wp:list-item -->
<!-- wp:list-item -->
<li><strong>Generate API Credentials</strong>: Generate the necessary API credentials (such as an API key or access token) and save them securely for future use.</li>

<hr class="wp-block-separator has-alpha-channel-opacity"/>
<!-- /wp:separator -->
<!-- wp:heading -->
<h2 class="wp-block-heading">Step 2: Configuring The Shopify API</h2>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p>For Shopify users:</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>Log into your Shopify admin dashboard and navigate to Settings -> Apps and Sales Channels. This area shows all the applications currently installed in your store.</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>To create a new custom application, click on the 'Develop apps' button located at the top right of the page.</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>If you're having trouble locating this option, refer to the screenshot of Shopify's backend admin console below.</p>
<!-- /wp:paragraph -->
<!-- wp:image {"id":3100,"sizeSlug":"full","linkDestination":"none"} -->
<figure class="wp-block-image size-full"><img src="https://five.co/wp-content/uploads/2024/06/Frame-64-1024x471-1.png" alt="Using Shopify as the data source for your sales tracking software." class="wp-image-3100"/></figure>
<!-- /wp:image -->
<!-- wp:paragraph -->
<p>Assign a name to the application (for this guide, we’ve named it 'fiveteststore', and we will use this name throughout).</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>Then, go to the 'Configuration' section and specify the API access scopes for the data you want to share with an external system, such as Products, Orders, Inventory, etc.</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>After completing the configuration, go to the 'API Credentials' tab. Shopify will prompt you to install your application. Once installed, Shopify will generate an Admin API access token. This token is only displayed once, so make sure to save it in a secure location for future use.</p>
<!-- /wp:paragraph -->
<!-- wp:image {"align":"center","id":3101,"width":"565px","height":"auto","sizeSlug":"full","linkDestination":"none"} -->
<figure class="wp-block-image aligncenter size-full is-resized"><img src="https://five.co/wp-content/uploads/2024/06/image-removebg-preview-1.png" alt="" class="wp-image-3101" style="width:565px;height:auto"/></figure>

<h3 class="wp-block-heading">Step 2: Integrating Shopify with Five</h3>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p>First, launch Five and click the yellow + button to create a new application. Give it a name and press save. Then, select Manage to start developing your application. This is the starting point for creating your custom app using Shopify data.</p>
<!-- /wp:paragraph -->
<!-- wp:image {"id":3103,"width":"840px","height":"auto","sizeSlug":"full","linkDestination":"none"} -->
<figure class="wp-block-image size-full is-resized"><img src="https://five.co/wp-content/uploads/2024/06/image-1-1024x576-1-1.png" alt="" class="wp-image-3103" style="width:840px;height:auto"/></figure>
<!-- /wp:image -->
<!-- wp:separator -->
<hr class="wp-block-separator has-alpha-channel-opacity"/>
<!-- /wp:separator -->
<!-- wp:paragraph -->
<p>Next we will use the Shopify API that we have just set up.</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>1. Begin by clicking on Data -> Connection Wizard.<br>The Connection Wizard in Five makes it easy to link to REST APIs and set up API endpoint mappings, simplifying your integration tasks.</p>
<!-- /wp:paragraph -->
<!-- wp:image {"id":3104,"sizeSlug":"full","linkDestination":"none"} -->
<figure class="wp-block-image size-full"><img src="https://five.co/wp-content/uploads/2024/06/image-2-1024x190-1.png" alt="" class="wp-image-3104"/></figure>
<!-- /wp:image -->
<!-- wp:paragraph -->
<p>2. Inside the Connection Wizard, click on the Read List Mapping tab. Here, enter the URLs for your API. The URL structure is:</p>
<!-- /wp:paragraph -->
<!-- wp:code -->
<pre class="wp-block-code"><code>https://{your_store_name}.myshopify.com/admin/api/{api_version}/products.json</code></pre>
<!-- /wp:code -->
<!-- wp:paragraph -->
<p>Replace <code>{your_store_name}</code> with the name of your store and <code>{api_version}</code> with the latest version of the API <a href="https://shopify.dev/docs/api/release-notes">which you can find here.</a></p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>(Note: For this guide, we'll be retrieving product details from the store. Make sure you have granted product access to the API during Step 1.)</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>3. Add your URL to Five's Connection Wizard. It should look something like this: Now, add your Admin API access token as a header.</p>

1,898,290 | The Benefits of Galvanized Steel Products for Long-Term Use | Galvanized Steel Products: Your Long-Term Solution Are you looking for a material to utilize for... | 0 | 2024-06-24T03:06:31 | https://dev.to/homans_ropikd_be5c3d3cbbf/the-benefits-of-galvanized-steel-products-for-long-term-use-574p | galvanized | Galvanized Steel Products: Your Long-Term Solution
Are you looking for a material to utilize for long-term tasks Galvanized steel products are the response Galvanized metal is a type of steel that has been coated with a layer of zinc to guard it from corrosion and rust. Here are five factors why Galvanized Steel products are the option that is most useful for long-term usage
Benefits of Galvanized Steel Products
Galvanized steel products have many advantages over other materials. First, it really is more durable, as the zinc coating adds an layer that is extra of to the steel. This will make it resistant to corrosion and rust for very long periods of time. Second, it is affordable, as the method of galvanization is cost-effective and is also environmentally friendly. Lastly, this is certainly versatile, as it can be used in various applications, including construction, automotive, and also in household appliances
Innovation in Galvanized Steel Products
Throughout the full years, there have been innovations in the galvanization procedure. One of these could be the utilization of hot-dip galvanization, a procedure that involves dipping the metal in a bath of molten zinc. This process creates a thicker layer of zinc, making the steel more durable and durable. Another innovation could be the use of galvannealing, a process that produces a material with both the characteristics of zinc and steel. This creates something that is even more resistant and durable to corrosion
Safety in Using Galvanized Steel Products
Galvanized steel products are safe to utilize and manage. It is because the zinc finish is non-toxic and doesn't pose any ongoing health threats. Additionally, galvanised steel sheet includes a melting that is high, which makes it a safe material to make use of in high-temperature environments. Moreover, galvanized metal services and products don't emit any harmful gases, making it a safe material to use inside
How to Use Galvanized Steel Items
Galvanized steel products are user friendly. They can be welded, cut, or drilled just like any other type of metal. However, when using these services and products, it is important to wear gear that is protective such as gloves and goggles, to prevent any injuries. Also, when cutting or grinding steel that is galvanized, proper air flow is necessary to prevent breathing of zinc fumes
Service and Quality of Galvanized Steel Items
Galvanized metal products are known for their durability and quality that is long-lasting. They've been designed to withstand weather that is harsh and resist harm from pests and insects.

1,896,647 | 8 Date Functions You Can Absolutely Write Without a Library | Hi everyone, It's Hudy again Date is one of the most popular object in Javascript that you're... | 0 | 2024-06-24T03:04:16 | https://dev.to/hudy9x/8-date-functions-you-can-absolutely-write-without-a-library-372f | Hi everyone, It's Hudy again
Date is one of the most popular object in Javascript that you're supposed to work with in at least one of your projects. And I'm sure that you also implement these function using the `Date` object for some cases:
- compare two dates
- get the last date of month
- convert date to readable version
- ... many more
So in this post, I'd like to share with you 8 date utilities function that I often use to manipulate the Date object in javascript.
## 1. Convert date to a readable version
If you have a list of activities and you'd like to display a readable version of date (ex: 2 min ago, 10 hours ago, 2 days ago) for straightforward and understandable when an activity happens.
Then you could try this.
```c
function toReadableDate(date) {
const AMIN = 60
const ADAY = AMIN * 24;
const minutes = calculateMinuteFromNow(date)
const isFuture = minutes < 0;
const absMinutes = Math.abs(minutes)
const r = n => Math.round(n)
const addAffix = minStr => {
if (isFuture) return `in ${minStr}`;
return `${minStr} ago`;
}
if (absMinutes < AMIN) {
return addAffix(`${minutes} minutes`)
}
if (absMinutes < ADAY){
return addAffix(`${r(absMinutes/AMIN)} hours`)
}
if (absMinutes === ADAY && !isFuture) {
return `yesterday`
}
if (absMinutes === ADAY && isFuture) {
return `tomorrow`
}
return addAffix(`${r(absMinutes/ADAY)} days`);
}
function calculateMinuteFromNow(date) {
const d1 = new Date(date);
const d2 = new Date();
const diff = d2.getTime() - d1.getTime();
return Math.round(diff / (1000 * 60)); // minutes
}
// Test
toReadableDate(new Date(2024, 5, 12)) // '11 days ago'
toReadableDate(new Date(2024, 5, 28)) // 'in 5 days'
```
## 2. Get the first/last date of month
The second function that I often used for getting first/last date in month. You can write it easily as follow.
```c
function getFirstDateOfMonth(date) {
const d = new Date(date)
d.setDate(1)
return d
}
function getLastDateOfMonth(date){
const d1 = new Date(date)
d1.setMonth(d1.getMonth() + 1)
d1.setDate(1)
d1.setHours(-1)
return d1.getDate()
}
// Test
getFirstDateOfMonth(new Date())
getLastDateOfMonth(new Date())
```
## 3. Compare two dates
There are two case occur in this function. First, you'd like to compare date and the second is you'd like to compare exact date and time.
```c
function compareDate(dateLeft, dateRight) {
const d1 = new Date(dateLeft)
const d2 = new Date(dateRight)
const d1Str = `${d1.getFullYear()}-${d1.getMonth()}-${d1.getDate()}`
const d2Str = `${d2.getFullYear()}-${d2.getMonth()}-${d2.getDate()}`
return d1Str === d2Str
}
```
The above version compares dates only by year, month and day. It doesn't consider hours, minutes and seconds. The following will handle comparisions based on the exact date and time.
```c
function compareExactDate(dateLeft, dateRight){
return new Date(dateLeft).getTime() === new Date(dateRight).getTime()
}
```
## 4. Calculate the duration between two dates
The fourth function will helps you calculate the number of days/hours/minutes between two dates.
```c
function getDuration(dateLeft, dateRight){
const DAY = 24
const HOUR = 60
const MIN = 60
const d1 = new Date(dateLeft);
const d2 = new Date(dateRight);
const diff = d2.getTime() - d1.getTime();
return Math.round(diff / (1000 * MIN * HOUR * DAY));
}
// Test
getDuration(new Date(2024, 5, 11) , new Date(2024, 5, 13))
```
The earlier function only returns the number of days. You can custom the formula to return value in hour, minute as you wish.
## 5. Get list of month/day in alphabet or number
Sometimes, you want to get the list of month or day in alphabet for displaying on a select box or calendar.
```c
function getMonthList(){
const months = ['January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December']
return months
}
function getDayList() {
const days = ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday']
return days
}
function getCompactDayList() {
return getDayList().map(d => d.slice(0,3))
}
function getCompactMonthList() {
return getMonthList().map(m => m.slice(0,3))
}
function getMonthOptions(compact) {
const options = compact ? getCompactMonthList() : getMonthList()
return options.map((v, i) => ({title: v, id: i}))
}
function getDayOptions(compact) {
const options = compact ? getCompactDayList() : getDayList()
return options.map((v, i) => ({title: v, id: i}))
}
```
## 6. Get the first (monday) and last day (saturday) of week
For those unfamiliar with the `Date` object, keep in mind that `Sunday` is assigned `0` and `Saturday` is assigned `6`.
```c
function getFirstDayOfWeek(date) {
const d = new Date(date)
const day = d.getDay()
const currentDate = d.getDate()
d.setDate(currentDate - (day - 1))
return d;
}
// Test
getFirstDayOfWeek(new Date(2024, 5, 22))
```
```c
function getLastDayOfWeek(date) {
const d = new Date(date)
const day = d.getDay()
const currentDate = d.getDate()
d.setDate(currentDate + (6 - day))
return d;
}
// Test
getLastDayOfWeek(new Date(2024, 5, 16))
```
## 7. Get the list of week by a specified date
I often use this function to generate labels for a week's worth of data, which I then use on the x-axis of my visualizations.
```c
function getListOfWeekByDate(date) {
const day = date.getDay()
const week = []
const weekLen = 7
let i = 0
while (i < weekLen) {
const d = new Date(date.getTime())
const distance = day - i
d.setDate(d.getDate() - distance)
week.push(d)
i++
}
return week
}
// Test
getListOfWeekByDate(new Date(2024, 5, 18))
```
## 8. Get all week of month
The last function will return all weeks of month. I ultilize `getLastDateOfMonth`, `getFirstDateOfMonth` and `getListOfWeekByDate` from the above functions to create this function.
```c
// 1. we generate the first week of month
// by using `getFirstDateOfMonth` and `getListOfWeekByDate`
function getFirstWeekOfMonth(d) {
const firstDateOfMonth = getFirstDateOfMonth(d)
return getListOfWeekByDate(firstDateOfMonth)
}
function getFullWeekOfMonth(d) {
const weeks = []
const month = d.getMonth()
const lastDateInThisMonth = getLastDateOfMonth(d)
// 1. get the first week
const firstWeek = getFirstWeekOfMonth(d)
weeks[0] = firstWeek
let going = true
while (going) {
const lastWeek = weeks[weeks.length - 1]
// 5.1 until no week found
if (!lastWeek) {
going = false
break
}
// 2. get the last date of the last week
const lastDate = lastWeek[lastWeek.length - 1]
const ldate = lastDate.getDate()
const lmonth = lastDate.getMonth()
// 5.2 or that last date belongs to next month
if (lmonth > month || ldate === lastDateInThisMonth) {
going = false
break
}
// 3. increase the last date to 1
const nextDate = new Date(lastDate.getTime())
nextDate.setDate(nextDate.getDate() + 1)
// 4. generate the week by a new date
// then keep going
const week = getListOfWeekByDate(nextDate)
weeks.push(week)
}
return weeks
}
```
## Conclusion
So, I hope this post provided you some useful things. If you have a better version of the above functions or want to share yours, go ahead, I'd love to learn from you guys.

This blog will break down the principles of authentication in Next.js applications, walk through the code, and explain new features and APIs. We'll also highlight best practices and common pitfalls to be aware of. Let's get started!
## Getting Started with Authentication
Authentication usually begins with a sign-up process. We need to create a form to capture the user's name, email, and password.
### Step 1: Creating the Sign-Up Form
First, let's create a form to capture user details. When the form is submitted, it invokes a server action.
```jsx
import { useServer } from 'next/server';
import { useActionState } from 'next/action';
function SignUpForm() {
const action = useServer('signupAction');
const { pending, error } = useActionState(action);
return (
<form onSubmit={action}>
<input name="name" placeholder="Name" required />
<input type="email" name="email" placeholder="Email" required />
<input type="password" name="password" placeholder="Password" required />
<button type="submit" disabled={pending}>
{pending ? 'Submitting...' : 'Sign Up'}
</button>
{error && <p>{error.message}</p>}
</form>
);
}
```
### Step 2: Server Action for Sign-Up
In a new file, we'll create the server-side function that handles form submission. We'll validate the incoming fields before performing any authentication logic.
```typescript
import { z } from 'zod';
import { hash } from 'bcryptjs';
import { prisma } from '../lib/prisma';
import { createSession } from '../lib/session';
export const signupAction = async (formData) => {
const schema = z.object({
name: z.string().min(1),
email: z.string().email(),
password: z.string().min(6),
});
const { success, error } = schema.safeParse(formData);
if (!success) {
return { error: 'Invalid input' };
}
const { name, email, password } = formData;
const hashedPassword = await hash(password, 10);
const user = await prisma.user.create({
data: { name, email, password: hashedPassword },
});
const session = await createSession(user.id);
return { session };
};
```
### Step 3: Session Management
To persist user sessions across requests, we'll create a file for session management logic, including utility functions to create, verify, update, and delete sessions.
```typescript
import { sign, verify } from 'jsonwebtoken';
import { serialize, parse } from 'cookie';
const secretKey = process.env.JWT_SECRET;
export const createSession = (userId) => {
const token = sign({ userId }, secretKey, { expiresIn: '1h' });
const cookie = serialize('session', token, { httpOnly: true, maxAge: 3600 });
return { cookie, userId };
};
export const verifySession = (req) => {
const { session } = parse(req.headers.cookie || '');
if (!session) return null;
try {
const payload = verify(session, secretKey);
return payload.userId;
} catch {
return null;
}
};
export const deleteSession = () => {
const cookie = serialize('session', '', { httpOnly: true, maxAge: -1 });
return { cookie };
};
```
### Step 4: Integrating Session Creation in Sign-Up
In the sign-up action, we'll use the `createSession` function to create a session for the user upon successful registration.
```typescript
const { name, email, password } = formData;
const hashedPassword = await hash(password, 10);
const user = await prisma.user.create({
data: { name, email, password: hashedPassword },
});
const { cookie, userId } = await createSession(user.id);
return {
headers: { 'Set-Cookie': cookie },
userId,
};
```
## Authorization: Controlling Access
Next, we need to decide what routes and data a user can access based on their roles or permissions. This is known as authorization.
### Middleware for Authorization Checks
We can handle some authorization logic in middleware, checking if the current route is protected.
```typescript
import { NextResponse } from 'next/server';
import { verifySession } from '../lib/session';
export function middleware(req) {
const userId = verifySession(req);
if (!userId && req.url.pathname.startsWith('/dashboard')) {
return NextResponse.redirect('/login');
}
return NextResponse.next();
}
```
### Protecting Data with a Data Access Layer
It's best practice to keep authorization logic close to where data is fetched using a data access layer. This ensures security and consistency.
```typescript
import { prisma } from '../lib/prisma';
import { verifySession } from '../lib/session';
export const getUser = async (req) => {
const userId = verifySession(req);
if (!userId) throw new Error('Unauthorized');
const user = await prisma.user.findUnique({ where: { id: userId } });
return user;
};
```
### Minimizing Data Exposure
To reduce the risk of data leaks, minimize the data returned from APIs.
```typescript
export const getUser = async (req) => {
const userId = verifySession(req);
if (!userId) throw new Error('Unauthorized');
const user = await prisma.user.findUnique({
where: { id: userId },
select: { name: true, email: true },
});
return user;
};
```
## Conclusion
We've covered the main topics of authentication in Next.js apps, including creating sign-up forms, handling sessions, and authorization. Here are the key takeaways:
- Use middleware for optimistic non-blocking checks.
- Perform data fetching and compute-intensive checks within server actions.
- Keep authorization logic close to data fetching to ensure security.
- Minimize the data returned from APIs to reduce the risk of accidental leaks.

1,898,282 | Crafting a social connector for Logto | Learn how to create a custom social connector for Logto in just a few steps. ... | 0 | 2024-06-24T02:45:06 | https://blog.logto.io/crafting-social-connector/ | webdev, programming, identity, opensource | Learn how to create a custom social connector for Logto in just a few steps.
---
# Background
Social sign-in is a must for modern apps. It simplifies the user registration process, enhances user experience, and increases user engagement and conversion rate. In Logto, we use social connectors to sign in with a third-party social identify provider.
# What is a "connector"?
Connector is a piece of mini-program that connects Logto with a third-party service. It is responsible for handling the sign-in flow, exchanging tokens, and fetching user information from the third-party service.
Logto offers a rich set of official connectors designed to simplify integration for various social platforms. As of today, there are already 30+ connectors in total, within which 10+ connectors are contributed by our open-source community. And we expect the numbers to grow rapidly in the future.
However, we understand that there are still many other platforms that do not have Logto's official support at the moment. Luckily, as an open-source platform, you can always create your own custom connectors with ease. So in this post, let's walk you through how you can create a custom social connector for Logto in just a few steps.
# The sign-in flow
Before we start, let's understand the how the social sign-in flow works in Logto.
# Now let's get started
The fastest way to get yourself started is to copy the code from an existing official connector and modify it to fit your needs. Let's take the GitHub connector as an example.
### Step 1: Clone an existing connector package
In a connector source folder, you will find the following files:
- `index.ts`: The main entry file of the connector.
- `constant.ts`: The constants used in the connector.
- `types.ts`: The TypeScript types used in the connector.
- `index.test.ts`: The test cases for the connector.
- `mock.ts`: The mock data used in the connector test cases.
Besides these files, you will also need to provide a `README.md` file to describe the connector, a `logo.svg` (optionally a `logo-dark.svg` for better dark mode user experience), and a `package.json` file to define the npm package information.
### Step 2: Modify the main entry file (index.ts)
In the `index.ts` file, you will find most of the connector logic. There are typically 4 functions you need to implement:
- `getAuthorizationUri`: Generate the authorization URI for the third-party social platform. For GitHub, it would be: `https://github.com/login/oauth/authorize?client_id={clientId}&redirect_uri={redirectUri}&state={state}`. Refer to the developer documentation of your target social platform to get the correct URI.
- `authorizationCallbackHandler`: Safeguard the returned parameter values in the authorization callback URI, extract the authorization `code` and handle potential errors.
- `getAccessToken`: Exchange the authorization `code` for an access token.
- `getUserInfo`: Fetch user information from the third-party social platform with the access token.
Most of the other common logics have been taken care of in the Logto connector kit, which should make your work easier.
Finally, in the end of the file, you will just need to export the connector object, following the same code structure as the GitHub connector.
```
const createGithubConnector: CreateConnector<SocialConnector> = async ({ getConfig }) => {
return {
metadata: defaultMetadata,
type: ConnectorType.Social,
configGuard: githubConfigGuard,
getAuthorizationUri: getAuthorizationUri(getConfig),
getUserInfo: getUserInfo(getConfig),
};
};
```
### Step 3: Test the connector
**Unit test**
First, write some unit test cases and make sure the basic functionalities work as expected.
**Local test**
- Setup Logto in your local environment: Logto provides several ways to run locally, you can either use CLI, or docker, or even build from source code. Check out the documentations for [more details](https://docs.logto.io/docs/references/using-cli/install-logto/).
- Link your custom connector to your Logto instance: Use the CLI to create a symbolic link of your connector to the Logto instance. [More details](https://docs.logto.io/docs/references/using-cli/manage-connectors/#link-local-connectors).
```
cd logto
npx @logto/cli connector link -p .
```
- After linking the connector, you should see it in the `<logto-root-path>/packages/core/connectors` folder.
- Restart your Logto instance, go to the Logto Admin Console, you should be able to see it in the social connectors list.
- Configure your connector in "Sign-in experience" -> "Sign-up and sign-in" -> "Social sign-in". And try it in our demo app with the "Live preview" feature.
### Step 4 (optional): Publish the connector
You can publish your connector to NPM, and share it with the community. Or even raise a PR and contribute to Logto official GitHub repository to make it an official supported connector. Official connectors will be maintained by Logto dev team and made available to both open-source and Logto Cloud users.
# Summary
Creating a custom social connector for Logto is not as hard as you might think. With the help of the Logto connector kit and good examples of code, you can easily create a connector in just a few steps.
And by contributing your connector, you can help more users to enjoy the social platform you bring in to Logto family.

1,898,277 | HIRE A FAST & QUALIFIED CRYPTOCURRENCY RECOVERY SPECIALIST\\FOLKWIN EXPERT RECOVERY. | Nowadays fortunes are made and lost in the blink of an eye, I found myself in a nightmare of my own... | 0 | 2024-06-24T02:30:47 | https://dev.to/bernhard_dieter_7e4a65f5b/hire-a-fast-qualified-cryptocurrency-recovery-specialistfolkwin-expert-recovery-1ak4 |
Nowadays fortunes are made and lost in the blink of an eye, I found myself in a nightmare of my own making. With $90,000 worth of various Cryptocurrencies held hostage on my Coinbase account, I was thrust into a battle against an unseen adversary—a cunning hacker who sought to strip me of my hard-earned assets. Despite possessing mountains of evidence and a wealth of information detailing the nefarious intrusion into my account, Coinbase proved to be an impenetrable fortress, impervious to my pleas for assistance. Faced with the grim reality that all hope was lost, I turned to unconventional avenues in search of salvation. It was through a chance encounter with a concerned officer from our local police department in Georgetown, Texas, that a glimmer of hope emerged amidst the darkness. Drawing from his own experiences with victims of similar cybercrimes, the officer shared with me a tale of triumph against the odds—a tale of a victim who had enlisted the services of a renowned hacker known as (( FOLKWIN Expert Recovery )). Intrigued by the prospect of turning the tables on my assailant, I reached out to (( FOLKWIN Expert Recovery )) with a mix of apprehension and desperation. Their reputation preceded them, with tales of their unparalleled expertise in countering hackers and reclaiming stolen assets spreading far and wide. Skepticism gnawed at the edges of my consciousness as I awaited their response, unsure if salvation awaited or if my plight would only deepen. To my astonishment, (( FOLKWIN Expert Recovery )) responded with alacrity, extending a lifeline in the form of a sincere contract outlining the terms of our collaboration. With nothing left to lose and everything to gain, I affixed my signature to the document, placing my fate in their capable hands. What followed can only be described as a whirlwind of emotions—a rollercoaster ride of anticipation, anxiety, and ultimately, euphoria. Shock messages flooded my inbox, heralding the miraculous restoration of access to my Coinbase account and the return of my precious crypto investments. With trembling hands, I logged in, scarcely daring to believe that salvation had finally arrived. And there it was, a sight for sore eyes — A digital treasure trove once lost, now miraculously restored. My coins, my lifeline in the volatile world of cryptocurrency, sat proudly in my wallet, a testament to the indomitable spirit of resilience and redemption.

1,898,276 | Rust Core Concepts List | When I first started learning Rust, I was immediately struck by its unique approach to memory safety... | 0 | 2024-06-24T02:30:14 | https://dev.to/ashsajal/rust-core-concepts-list-27of | rust, beginners, programming, coding | When I first started learning Rust, I was immediately struck by its unique approach to memory safety and concurrency. Rust is a systems programming language that aims to provide both performance and safety, making it a powerful tool for developers who want to write efficient and reliable software. To help other beginners navigate the learning curve, I've organized some of the fundamental concepts of Rust into an easy-to-follow guide.
Here's a breakdown of core concepts in Rust, organized for learning:
**1. Ownership and Borrowing**
* **Ownership:** A fundamental concept in Rust. Each value in Rust has a single owner. When the owner goes out of scope, the value is dropped (cleaned up).
* **Borrowing:** Allows you to access data owned by another variable without taking ownership. Borrows have rules to prevent data corruption (e.g., multiple mutable borrows at the same time).
* **References:** Pointers that allow you to access data owned by other variables. They are immutable by default, but you can create mutable references.
**2. Data Types**
* **Scalar Types:** Represent single values:
* **Integers:** `i8`, `i16`, `i32`, `i64`, `i128`, `isize` (signed), `u8`, `u16`, `u32`, `u64`, `u128`, `usize` (unsigned)
* **Floating-Point:** `f32`, `f64`
* **Booleans:** `bool` (true or false)
* **Characters:** `char` (Unicode characters)
* **Compound Types:** Combine multiple values:
* **Tuples:** Fixed-size collections of different data types.
* **Arrays:** Fixed-size collections of the same data type.
* **Slices:** Dynamically sized views into arrays.
* **Strings:** Immutable sequences of characters.
* **Structs:** Custom data structures that group related data together.
* **Enums:** Allow you to define a type that can have a fixed set of values.
**3. Control Flow**
* **`if` Statements:** Execute code blocks conditionally based on a boolean expression.
* **`else` and `else if`:** Provide alternative code blocks to execute if the `if` condition is false.
* **`match` Statements:** Pattern matching, allowing you to compare a value against multiple patterns and execute different code blocks based on the match.
* **Loops:**
* **`loop`:** Executes a block of code repeatedly.
* **`while`:** Executes a block of code as long as a condition is true.
* **`for`:** Iterates over a sequence of values.
* **`for in`:** Iterates over the elements of an array or slice.
**4. Functions**
* **Defining Functions:** Use the `fn` keyword to define functions.
* **Parameters and Arguments:** Functions can take input parameters and return values.
* **Return Values:** Functions can return a single value or a tuple of values.
* **Methods:** Functions associated with a specific data type (structs, enums).
**5. Modules and Crates**
* **Modules:** Organize your code into logical units.
* **Crates:** The building blocks of Rust projects. They can contain multiple modules.
* **`use` Keyword:** Brings items from other modules into scope.
* **`extern crate` (deprecated):** Used to bring external crates into scope.
**6. Error Handling**
* **`Result` Type:** Represents either a successful value or an error.
* **`Option` Type:** Represents either a value or the absence of a value.
* **`unwrap()`:** Retrieves the value from a `Result` or `Option`, panicking if the value is not present.
* **`expect()`:** Similar to `unwrap()`, but allows you to provide a custom error message.
* **`match` for Error Handling:** Use `match` to handle different error cases.
**7. Traits**
* **Traits:** Define shared behavior for different types.
* **Implementing Traits:** Implement traits for your custom types to provide the specified behavior.
* **Generic Functions:** Functions that can work with different types by using traits.
**8. Structs and Enums**
* **Structs:** Custom data structures that group related data together.
* **Enums:** Allow you to define a type that can have a fixed set of values.
* **Pattern Matching with Enums:** Use `match` to handle different enum variants.
**9. Lifetime Annotations**
* **Lifetimes:** Used to specify the duration of a reference's validity.
* **Lifetime Elision:** Rust can often infer lifetimes automatically, but you may need to provide explicit annotations in some cases.
**10. Macros**
* **Macros:** Code that generates other code.
* **Declarative Macros:** Define custom syntax.
* **Procedural Macros:** More powerful macros that can manipulate the Rust compiler's AST.
**11. Asynchronous Programming**
* **`async` and `await`:** Enable asynchronous programming, allowing you to write non-blocking code.
* **Futures:** Represent the eventual result of an asynchronous operation.
* **`tokio`:** A popular asynchronous runtime for Rust.
**12. Memory Management**
* **Stack and Heap:** Rust manages memory automatically, using the stack for local variables and the heap for dynamically allocated data.
* **Automatic Memory Management:** Rust's ownership and borrowing system ensures that memory is freed when it's no longer needed, preventing memory leaks.
**13. Cargo**
* **Cargo:** Rust's build system and package manager.
* **`Cargo.toml`:** A file that defines your project's dependencies and metadata.
* **`Cargo.lock`:** A file that locks down the versions of your dependencies.
**14. Standard Library**
* **`std`:** Rust's standard library, providing a wide range of utilities and data structures.
* **`io`:** Input/output operations.
* **`fs`:** File system operations.
* **`collections`:** Data structures like vectors, hash maps, and sets.
* **`str`:** String manipulation.
**15. Testing**
* **Unit Tests:** Test individual functions or modules.
* **Integration Tests:** Test how different parts of your code interact.
* **`#[test]` Attribute:** Mark functions as unit tests.
* **`cargo test`:** Run tests using Cargo.
**16. Documentation**
* **`#[doc]` Attribute:** Add documentation comments to your code.
* **`cargo doc`:** Generate documentation for your project.
**17. Safety**
* **Memory Safety:** Rust prevents memory leaks and dangling pointers.
* **Data Race Prevention:** Rust's ownership system prevents multiple threads from accessing the same data concurrently without proper synchronization.

## Introduction

[nako_sleep_9h]: https://twitter.com/nako_sleep_9h
When we first learn [Nerves], one of the things we come up with is blinking LEDs on a breadboard.
Today I'd like to try one implementation using GenServer.
This is actually my outcome at this event I participated in last weekend "[Shop for parts in Akihabara and get started on Nerves right away!](https://piyopiyoex.connpass.com/event/317734/)". It was so much fun hanging out in [Akihabara, Tokyo](https://en.wikipedia.org/wiki/Akihabara) with [Nerves] enthusiasts.
Thank you very much to the organizers [myasu] and [nako_sleep_9h]!
[myasu] is very knowledgeable about electric and electronic stuff. I learned tons of pro tips from him, which I might write up as my future posts. He is the author of this book about Nerves.

## Nerves Livebook
There are more than a few ways to get started with [Nerves] IoT projects but one of the easiest is to use prebuild [Nerves Livebook] firmware. [Nerves Livebook] allows us to control our target devices such as Raspberry Pi, doing Elixir coding in a web browser.
https://github.com/nerves-livebook/nerves_livebook/blob/main/README.md
## Blink using Circuits GPIO
[Nerves Livebook] has a nice tutorial notebook about how to use the [circuits_gpio] package to control a [GPIO] as an output, and blink an LED. It shows us what electric parts we need minimally and how we wire them before getting down to business.
https://github.com/nerves-livebook/nerves_livebook/blob/main/priv/samples/basics/blink.livemd
## Wrapping our LED blinking logic in GenServer
When we want to repeat the blinking forever but want to stop at some stage without restarting the device, it is nice to prepare a [GenServer] that manages the LED blinking. There can be many ways to achieve similar effect but here is one implementation using GenServer.
First, let's write a simple module that wraps [GPIO]-related logic within so that we can forget about how exactly we need to communicate with our LEDs.
```elixir
defmodule LedBlink do
def open(led_pin) do
Circuits.GPIO.open(led_pin, :output)
end
def close(led_pin) do
Circuits.GPIO.close(led_pin)
end
def toggle(gpio, 1), do: off(gpio)
def toggle(gpio, 0), do: on(gpio)
def toggle(gpio, _), do: on(gpio)
def on(gpio) do
:ok = Circuits.GPIO.write(gpio, 1)
{:ok, 1}
end
def off(gpio) do
:ok = Circuits.GPIO.write(gpio, 0)
{:ok, 0}
end
end
```
Then next, we make a [GenServer] that lets an LED blink forever.
```elixir
defmodule BlinkServer do
use GenServer, restart: :temporary
require Logger
@run_interval_ms 1000
## Client
@doc """
Start a BlinkServer for the provided GPIO pin. It lets the LED blink forever.
### Examples
iex> BlinkServer.start_link(led_pin: "GPIO17")
"""
def start_link(opts) do
GenServer.start_link(__MODULE__, opts, name: __MODULE__)
end
def stop() do
GenServer.stop(__MODULE__)
end
## Callbacks
@impl true
def init(opts) do
led_pin = Access.fetch!(opts, :led_pin)
initial_state = %{
gpio_ref: nil,
led_state: 0,
led_pin: led_pin
}
{:ok, initial_state, {:continue, :init_gpio}}
end
@impl true
def handle_continue(:init_gpio, state) do
case LedBlink.open(state.led_pin) do
{:ok, gpio_ref} ->
new_state = %{state | gpio_ref: gpio_ref}
send(self(), :toggle_led_state)
{:noreply, new_state}
{:error, error} ->
{:stop, error}
end
end
@impl true
def handle_info(:toggle_led_state, state) do
{:ok, new_led_state} = LedBlink.toggle(state.gpio_ref, state.led_state)
new_state = %{state | led_state: new_led_state}
Logger.debug("toggled LED: #{new_state.led_state}")
Process.send_after(self(), :toggle_led_state, @run_interval_ms)
{:noreply, new_state}
end
@impl true
def terminate(reason, state) do
LedBlink.close(state.gpio_ref)
Logger.debug("terminated: #{reason}")
:ok
end
end
```
Here is how to use our BlinkServer.
When starting BlinkServer, we specify the GPIO pin we use for our LED.
When we are done experimenting, we can stop our running BlinkServer worker.
```elixir
Logger.configure(level: :debug)
BlinkServer.start_link(led_pin: "GPIO17")
Process.sleep(10_000)
BlinkServer.stop()
```
This implementation of BlinkServer is a singleton [GenServer], meaning we are not allowed to start more than one BlinkServer workers. So if we change our mind on the [GPIO] pin we use, for example, we would need to stop the worker and start a new worker with different options.
## circuits_gpio package
[circuits_gpio] is the one that lets us control [GPIO] in our Elixir code.
## Wrapping up
We wrote a simple [GenServer] that lets our LED blink.
Once you get a feel of it, I would like to see your LED blinking logic. Please share!

1,898,262 | How to Seamlessly Integrate OSS with Alibaba Cloud Elasticsearch Using Regular Service Roles | Overview Regular service roles are a type of RAM role that authorizes Alibaba Cloud... | 0 | 2024-06-24T01:46:00 | https://dev.to/a_lucas/how-to-seamlessly-integrate-oss-with-alibaba-cloud-elasticsearch-using-regular-service-roles-59lm | beginners, programming, tutorial, react | ## Overview
Regular service roles are a type of RAM role that authorizes Alibaba Cloud services to access each other securely. This guide provides a step-by-step approach to creating and managing a regular service role for [Alibaba Cloud Elasticsearch](https://www.alibabacloud.com/en/product/elasticsearch) to upload plug-ins or dictionary files from your Object Storage Service (OSS) securely.
<a name="fAR2N"></a>
### What is a Regular Service Role?
A regular service role in Alibaba Cloud is a RAM role authorized to act on behalf of other Alibaba Cloud services. This role ensures seamless and secure integration between two Alibaba Cloud services without changing public read permissions.
<a name="h7wHB"></a>
## Step 1: Create a Regular Service Role
If the regular service role does not exist when you upload a dictionary via an OSS URL, you must create this role and attach the required policy.
1. **Trusted Service Name**: elasticsearch.aliyuncs.com
2. **Role Name**: AliyunElasticsearchAccessingOSSRole
3. **Policy Name**: AliyunElasticsearchAccessingOSSRolePolicy
<a name="DGRuR"></a>
#### Policy Document:
```
1{
2 "Version": "1",
3 "Statement": [
4 {
5 "Action": [
6 "oss:GetObject",
7 "oss:GetObjectMetadata",
8 "oss:GetObjectMeta"
9 ],
10 "Resource": "*",
11 "Effect": "Allow"
12 }
13 ]
14}
```
<a name="s8DFV"></a>
## Step 2: Attach the Policy to the Regular Service Role
Log in to the RAM console and attach the above policy to the AliyunElasticsearchAccessingOSSRole. This enables Elasticsearch to assume this role to access files in the OSS URL and update dictionaries based on the file, ensuring data security.
<a name="pGStV"></a>
### Example of Limiting the Permissions of the Regular Service Role
To create more secure and granulated permissions, you can create a custom RAM policy and attach it to the regular service role.
<a name="rS3D0"></a>
#### Example Custom Policy
```
1{
2 "Version": "1",
3 "Statement": [
4 {
5 "Action": [
6 "oss:GetObject",
7 "oss:GetObjectMetadata",
8 "oss:GetObjectMeta"
9 ],
10 "Resource": [
11 "acs:oss:*:193248xxxxxxx:*"
12 ],
13 "Effect": "Allow",
14 "Condition": {
15 "StringEquals": {
16 "oss:BucketTag/key1":"value1"
17 }
18 }
19 }
20 ]
21}
```
<a name="POGhI"></a>
### Adding Tags to a Bucket
To manage permissions efficiently, you can add tags to buckets and control access based on these tags.
1. Log on to the OSS console.
2. In the left-side navigation pane, click Buckets. Find and click the desired bucket.
3. Choose Bucket Settings > Bucket Tagging from the left-side navigation tree.
4. On the Bucket Tagging page, click Create Tag and add the desired tag to the bucket.
<a name="RNYqh"></a>
### Uploading a Dictionary File
To upload a dictionary file from OSS:
1. Log in to the Elasticsearch console.
2. Use the OSS URL of the file to upload the plug-in or dictionary file.
<a name="wL7TK"></a>
## Deleting the Regular Service Role
If you need to delete the regular service role, you can do so in the RAM console. Note that after deletion, features depending on this role will cease to function.<br />For more detailed information, visit [RAM role overview](https://www.alibabacloud.com/help/doc-detail/116056.htm) and [Alibaba Cloud Elasticsearch](https://www.alibabacloud.com/en/product/elasticsearch).
<a name="mSMMa"></a>
## FAQ

### Q: Why is the ElasticsearchNoPermissionForCurrentBucket error received during operations like UpdateDict or UpdateHotIkDicts?
A: For Elasticsearch clusters using the cloud-native control architecture, only the regular service role for Elasticsearch can enable the clusters to read dictionary files stored in OSS. You must complete the authorization on the authorization page. This role is necessary for scenarios such as updating OSS-based synonym dictionaries, standard rolling updates of IK dictionaries, and dictionary updating for the analysis-aliws plug-in.

#### What is OOP?
Object-Oriented Programming (OOP) is a programming paradigm that uses "objects" to design applications and computer programs. It utilizes several principles such as inheritance, encapsulation, polymorphism, and abstraction to create modular and reusable code.
#### Key Principles of OOP
1. **Encapsulation**
2. **Inheritance**
3. **Polymorphism**
4. **Abstraction**
---
### Basic Definitions of Class and Object
**Class:**
A class in programming is a blueprint or prototype that defines the attributes (data) and methods (functions) that the objects created from the class will have. It is a way to encapsulate data and functionality together. In simpler terms, a class is like a template for creating objects.
**Object:**
An object is an instance of a class. It is a specific implementation of the class template, containing real values instead of variables. Objects are used to interact with the data and functions defined in the class.
In the image, we see a representation of a class and an object using the concept of a Pokémon, specifically Pikachu.
- **Class**: The top part of the image shows a class named "Pokemon." This class defines the structure that all Pokémon objects will follow.
- **Attributes**: These are the properties or data stored in the class. For the "Pokemon" class, the attributes are:
- `Name`: Pikachu
- `Type`: Electric
- `Health`: 70
- **Methods**: These are the functions or behaviors that objects created from the class can perform. The methods in the "Pokemon" class are:
- `attack()`
- `dodge()`
- `evolve()`
- **Object**: On the left side of the image, we have Pikachu, which is an instance of the "Pokemon" class. Pikachu has specific values for the attributes defined in the class:
- `Name`: Pikachu
- `Type`: Electric
- `Health`: 70
This image illustrates the relationship between a class (the blueprint) and an object (the instance). Pikachu, the object, is created based on the "Pokemon" class, inheriting its structure and functionalities.

### Encapsulation
**Definition:**
Encapsulation is the practice of wrapping the data (attributes) and the methods (functions) that operate on the data into a single unit, or class. It also involves restricting direct access to some of the object's components, which can help prevent accidental interference and misuse of the data.
**Daily Life Example:**
Consider a coffee machine. You interact with it by pressing buttons to make coffee, fill the water tank, etc. You don't need to know the internal mechanics of how it heats the water or brews the coffee. The machine encapsulates all the details.
**Python Code Example:**
```python
class CoffeeMachine:
def __init__(self):
self._water_level = 0 # The underscore indicates this attribute is intended to be private.
def fill_water_tank(self, amount):
self._water_level += amount
print(f"Water tank filled. Current level: {self._water_level} ml")
def make_coffee(self):
if self._water_level > 0:
print("Coffee made!")
self._water_level -= 50 # assume each coffee uses 50ml
else:
print("Please fill the water tank.")
def get_water_level(self):
return self._water_level
# Using the CoffeeMachine class
machine = CoffeeMachine()
machine.fill_water_tank(100)
machine.make_coffee()
machine.make_coffee()
print(f"Remaining water level: {machine.get_water_level()} ml")
```
**Explanation:**
- **Class Definition**: We define a class `CoffeeMachine`.
- **Attributes**: `self._water_level` is an attribute that represents the water level in the machine. The underscore (`_`) before `water_level` is a convention indicating that this attribute is intended to be private.
- **Methods**:
- `fill_water_tank(amount)`: Adds the specified amount of water to the tank.
- `make_coffee()`: Makes coffee if there is enough water.
- `get_water_level()`: Returns the current water level.
- **Encapsulation**: The internal state (`_water_level`) is not directly accessible from outside the class, enforcing encapsulation.
### Inheritance
**Definition:**
Inheritance is a mechanism where a new class inherits attributes and methods from an existing class. The new class is called the derived (or child) class, and the existing class is the base (or parent) class.
**Daily Life Example:**
Consider a basic phone and a smartphone. A basic phone can make calls. A smartphone can make calls too, but it can also install apps, browse the internet, etc. The smartphone class can inherit the properties of the basic phone class and add additional features.
**Python Code Example:**
```python
class Phone:
def __init__(self, brand, model):
self.brand = brand
self.model = model
def make_call(self, number):
print(f"Calling {number} from {self.brand} {self.model}")
class Smartphone(Phone):
def __init__(self, brand, model, os):
super().__init__(brand, model) # Call the constructor of the parent class
self.os = os
def install_app(self, app_name):
print(f"Installing {app_name} on {self.brand} {self.model}")
# Using the Phone and Smartphone classes
basic_phone = Phone("Nokia", "3310")
smart_phone = Smartphone("Apple", "iPhone 14", "iOS")
basic_phone.make_call("123456789")
smart_phone.make_call("987654321")
smart_phone.install_app("WhatsApp")
```
**Explanation:**
- **Base Class (Phone)**:
- Attributes: `brand` and `model`.
- Method: `make_call(number)` which prints a calling message.
- **Derived Class (Smartphone)**:
- Inherits from `Phone`.
- Adds a new attribute `os`.
- Adds a new method `install_app(app_name)`.
- Uses `super()` to call the constructor of the `Phone` class.
### Polymorphism
**Definition:**
Polymorphism allows for methods to do different things based on the object it is acting upon, even though they share the same name.
**Daily Life Example:**
Consider a remote control that can work with multiple devices like a TV, DVD player, and sound system. You use the same `power_on` button to turn all these devices on, but the internal implementation for each device is different.
**Python Code Example:**
```python
class TV:
def power_on(self):
print("The TV is now ON")
class DVDPlayer:
def power_on(self):
print("The DVD Player is now ON")
class SoundSystem:
def power_on(self):
print("The Sound System is now ON")
# Function that uses polymorphism
def turn_on_device(device):
device.power_on()
# Using the function with different objects
tv = TV()
dvd_player = DVDPlayer()
sound_system = SoundSystem()
turn_on_device(tv)
turn_on_device(dvd_player)
turn_on_device(sound_system)
```
**Explanation:**
- **Classes (TV, DVDPlayer, SoundSystem)**: Each class has a `power_on()` method.
- **Function (turn_on_device)**: This function takes any device and calls its `power_on()` method.
- **Polymorphism**: The same `turn_on_device()` function works with different types of devices.
### Abstraction
**Definition:**
Abstraction is the concept of hiding the complex implementation details and showing only the essential features of the object.
**Daily Life Example:**
When you drive a car, you use the steering wheel, pedals, and gear shift. You don't need to understand how the engine or transmission system works to drive the car.
**Python Code Example:**
```python
from abc import ABC, abstractmethod
class Vehicle(ABC):
@abstractmethod
def start_engine(self):
pass
@abstractmethod
def stop_engine(self):
pass
class Car(Vehicle):
def start_engine(self):
print("Car engine started")
def stop_engine(self):
print("Car engine stopped")
class Motorcycle(Vehicle):
def start_engine(self):
print("Motorcycle engine started")
def stop_engine(self):
print("Motorcycle engine stopped")
# Using the classes
car = Car()
motorcycle = Motorcycle()
car.start_engine()
car.stop_engine()
motorcycle.start_engine()
motorcycle.stop_engine()
```
**Explanation:**
- **Abstract Base Class (Vehicle)**: Contains abstract methods `start_engine()` and `stop_engine()`.
- **Derived Classes (Car, Motorcycle)**: Implement the abstract methods.
- **Abstraction**: Users interact with the `start_engine()` and `stop_engine()` methods without needing to know how they are implemented.
conclusion
Object-Oriented Programming (OOP) is a programming paradigm centered around the concept of "objects" which can contain data, in the form of fields (often known as attributes), and code, in the form of procedures (often known as methods). The four key principles of OOP are encapsulation, inheritance, polymorphism, and abstraction. Encapsulation refers to bundling the data and methods that operate on the data within a single unit or class, and restricting access to some of the object's components, which helps maintain integrity and prevents unintended interference. Inheritance allows a new class to inherit attributes and methods from an existing class, fostering code reuse and logical hierarchy. Polymorphism enables methods to operate differently based on the object, allowing a unified interface to interact with different data types. Lastly, abstraction simplifies complex systems by exposing only the necessary parts, hiding the intricate details, and thus enhancing code readability and usability. Together, these principles promote modular, reusable, and maintainable code, making OOP a powerful and widely-used programming paradigm.
