Have you ever been to a website that loads super fast? Chances are it uses an SSG (Static Site Generator). It’s a tool that builds your site ahead of time, so when someone visits, they get the page instantly. No waiting around for things to load it’s just there.
What is Astro?
Astro is a modern Static Site Generator that focuses on delivering faster websites by sending as little javaScript as possible.
Unlike traditional javaScript frameworks, Astro renders pages at build time, creating static HTML that gets served directly to users.
One of its standout features is the island architecture, which lets you selectively hydrate only the parts of the page that need interactivity means you only load javaScript when it’s absolutely necessary.
