Key Features of Astro

Astro ships only the JavaScript needed for interactive components, keeping page loads ultra‑light.
It uses an island architecture that isolates interactive parts, allowing the rest of the page to be static HTML.
Developers can write pages in Markdown, MDX, or any templating language while still leveraging component frameworks.
Astro’s built‑in adapter system lets you deploy to Netlify, Vercel, Cloudflare Pages, or any Node.js server with a single command.
The framework supports TypeScript out of the box, providing type safety without extra configuration.
You can import React, Vue, Svelte, or Solid components side‑by‑side in the same project.
Astro’s dev server offers hot‑module replacement and fast rebuilds, speeding up the development cycle.
