Astro JS

Astro is a modern web framework designed to build fast, content-focused websites by minimizing unnecessary JavaScript. Its core purpose is to return to a performance-first model of the web, where HTML is delivered as static content by default and interactivity is added only where it is actually needed.

Astro introduces an “islands architecture”, which allows developers to render most of a page as static HTML while selectively hydrating individual components on the client. This approach significantly reduces JavaScript payloads, improves loading times, and enhances overall user experience.

By supporting multiple UI frameworks side by side and emphasizing build-time rendering, Astro enables developers to create scalable, maintainable, and performant websites without sacrificing modern development ergonomics.
