Astro is a modern static site generator that lets you use your favorite framework components, but only sends JavaScript when needed, resulting in exceptional performance.
Why Choose Astro?
Astro’s core advantage lies in its “zero JavaScript” philosophy. By default, Astro renders all components as static HTML and only sends JavaScript when needed. This means:
- Faster page loads: Reduced initial JavaScript bundle size
- Better SEO: All content is pre-rendered HTML
- Lower server costs: Static files can be hosted on any CDN
Getting Started
Installing Astro is simple:
npm create astro@latest
Then follow the prompts to choose your preferred template and configuration.
Component System
Astro supports components from multiple frontend frameworks, including React, Vue, Svelte, and more. You can mix and match components from these frameworks in the same project.
Performance Optimization
Astro provides multiple performance optimization options:
- Partial Hydration: Only hydrate components that need interactivity
- Code Splitting: Automatic code splitting, loading only what’s needed
- Image Optimization: Built-in image optimization
With these optimizations, you can build lightning-fast static sites.
