Description #
Alpine.js is a minimal JavaScript framework that uses a declarative syntax embedded directly in HTML to create interactive UIs. Its DSL (domain-specific language) allows developers to write reactive behavior inline using x- attributes.
History #
Alpine.js was created by Caleb Porzio in 2020 as a lightweight alternative to heavy frameworks like Vue or React. It was designed to bring reactivity and interactivity to HTML without leaving the markup or writing JavaScript files.
