What is Alpine?
Alpine.js offers you the reactive and declarative nature of big frameworks like Vue or React at a much lower cost. You get to keep your DOM, and sprinkle in behaviour as you see fit.
Alpine’s showstopper is it’s really small 6.4kb file size, with the added bonus of not requiring the use of a bundler or build process. Just load the tiny js file and you’re off.
Naturally this reduced file-size comes at a cost: there is no shadow DOM, and there is a limited set of built-in directives and magic properties to use (14 and 6 respectively). Don’t expect it to be right for every project.
But where Alpine succeeds is its ease of DOM manipulation: showing and hiding elements, binding user input, event listening, setting attributes dynamically.
Obviously this can all be done with an almost limitless number of existing frameworks already in the ecosystem, but again, the overhead with Alpine is miniscule.
What’s more? If you’re already familiar with Vue, you’ll be able to jump into Alpine straight away without any troubles, as the syntax is almost entirely borrowed from Vue (and by extension, Angular).
