Alpine.js Looks Promising

Alpine.js caught my eye, so I decided to give it a try.

What is this?

It's something like a UI library. It seems to occupy a similar space as React, Vue, Solid, or Svelte.
According to the official website, it's like "jQuery for the modern web."
But it's a bit different from those UI libraries.
It's very lightweight and incredibly simple!

Points that made me think Alpine.js looks awesome!

Here they are.

1. No TypeScript

Alpine.js doesn't have TypeScript.
You can develop casually without worrying about types!

2. Complete with just a <script> tag CDN

You can introduce it with just a <script> tag!

<script src="//unpkg.com/alpinejs" defer></script>

All you have to do is insert this into your HTML.
You don't need npm or anything. You can even complete everything within a single HTML file.

3. Simple

It's extremely simple!

<div x-data="{ open: false }">
  <button @click="open = !open">Toggle</button>
  <span x-show="open">
    Content...
  </span>
</div>

It looks like this. The data can be used within the element where x-data is defined.
It's like Vue.

You might think, "You say it's simple, but aren't there a lot of things starting with x-?"
In reality, that's not the case—there are only 23 attributes and such to use!

There are 15 starting with x-, 6 properties usable within scripts, and 2 methods for the global Alpine variable. Simple, right?

You can check these on the Alpine.js homepage.

What is it best used for?

You might think that things like "No TypeScript" and "completing with just a <script> tag" are convenient but could lead to poor maintainability.
You are right; I believe Alpine.js doesn't offer much in terms of maintainability and is unsuitable for large-scale projects.

However, it is great for when you want something quick and easy!
When you want to build simple tools or just play around with JavaScript.
You can use it casually without having to go through the trouble of setting up an environment with npm.
That, I think, is the beauty of Alpine.js.

Summary

Alpine.js is perfectly suited for small-scale development!
In those cases, I highly recommend it!
