What is Alpine.js?
Alpine.js is a lightweight JavaScript framework for composing behavior directly in your HTML. Think of it as Tailwind CSS for JavaScript - minimal, declarative, and stays in your markup. Perfect for adding interactivity to server-rendered pages without the overhead of larger frameworks. Features include reactive data, event listeners, and transitions. Used by Laravel developers and teams who want jQuery simplicity with modern reactivity.

Alpine.js FAQ
How does Alpine.js enable interactivity in web pages?
Alpine.js allows developers to compose behavior directly within their HTML using a minimal and declarative syntax. It provides features like reactive data, event listeners, and transitions to add interactivity without requiring a complex build step.
Which teams benefit most from using Alpine.js?

Can Alpine.js be used without a build step?
