Here are 6 of my favorite third-party libraries when building CLI applications using #NodeJS

Want to know why?👇🧵 commander ➡️ npm.im/commander

Simple yet powerful command-line argument parser. It automatically generates help messages and can be configured to support multiple commands.

I ❤️ it bc it's not prescriptive, you can organize the code as you want (1 file or more).

"Yo, why are #JavaScript and its ecosystem so messy?!" 😡

Well, I am glad you asked... Let me tell you a story! 🤓

🧵👇 For starting... #JavaScript was not designed to be the language that it is today!

JS was created in 1995 by @BrendanEich for Netscape, a web browser that was trying to come up with a language to make the web more interactive

I have been confused for a while on what's the best way to implement a "to string" functionality for a #Rust struct. 🦀

The reason why this has been confusing to me is that there are indeed many ways to do that and they all have different purposes!

This is what I learned

👇🧵 The first thing that you can do is to just implement a simple `to_string()` function directly on your struct!

Do you know what's in a #JWT token?

Here's a quick thread to learn something about this! 👇 A JWT token (JSON Web Token) is just a string with a well-defined format. A sample token might look like this:

```

@eleven_ty micro tip: Give eleventy some credit by injecting a "generator" meta tag in your HTML! 🔥

Frontpage and Dreamweaver used to get credit this way, why shouldn't we give Eleventy some credit too? 😇

(a short thread in 3 steps 👇) STEP 1. Create a data file in `_data/site.js` with the following content:

✨ Rob Pike's 5 Rules of #programming ✨

#golang #simplicity

🧵👇 1️⃣ You can't tell where a program is going to spend its time. Bottlenecks occur in surprising places, so don't try to second guess and put in a speed hack until you've proven that's where the bottleneck is.

Software engineering #anxiety, let's talk about it. Specifically, let me try to deconstruct my personal anxiety

🧵👇 1️⃣ classic impostor syndrome: it doesn't matter how good I actually am with some technology/tool/technique. Even if I can get the job done, it still feels far from adequate and I feel like I have to rush to get better to defend my job title & credibility...

I spoke about how #JavaScript module bundlers (those things like #Webpack) work under the hood yesterday at @coderful!

🗒Here's a short-ish summary:

1/ TLDR: Module bundlers like Webpack are not "complicated" or "magic" per se, the practice of module bundling is a complicated matter and you need to understand it before you can fully understand what a module bundler does and how to configure it correctly! 🦄

I love to use @StandardJS to enforce consistent code style in all my #JavaScript / #NodeJS projects. You can easily do that with:

```
npx standard
```

But I prefer to setup @geteslint for more extensibility.

🧵 Here's how I do it... 👇 1. Initialize a new project with:

```
mkdir new-project
cd new-project
npm init -y
```

Great #JavaScript array cheatsheet!

One thing that deserves a bit more info is that `.sort()`.

Check out below this tweet for more info if curious!

By default `.sort()` will sort the array items lexicographically (string sorting).

⚛️ Create #React App (CRA) it's a wonderful tool, but IMHO it tries to do too much and tends to give you a bloated setup.

If you are like me and prefer to start simple and build incrementally, here's a React scaffold alternative in just 10 simple-ish steps!

🧵 A thread 👇 1. 🥳 Create and init your project

mkdir my-new-react-project && cd my-new-react-project && npm init -y

What have you learned by using/studying different programming languages?

Here's my personal 🧵thread🧵, but I look forward to seeing your version of this :)

#learning #coding #PHP: sandboxing the lifecycle and data related to every request is often a good idea.

(@official_php)

@nim_lang just did a quick (& stupidly simple) benchmark comparing asyncHttpServer with a plain @nodejs http server. The #Nodejs server seems ~3.5x faster than the #nim one... I did expect opposite results! Am I doing something stupid or is this expected? After setting up the @nim_lang "-d:release" flag and changing the @nodejs implementation to use the cluster module, these are some new results.
