Building with Astro

Astro is a modern static site builder that offers incredible performance out of the box. Let’s explore some of its key features.

Why Astro?

Astro’s component islands architecture allows you to build interactive components while shipping zero JavaScript by default.

---
// Example Astro component
const greeting = "Hello, Astro!";
---

<div class="greeting">
  <h1>{greeting}</h1>
  <style>
    .greeting {
      color: red;
    }
  </style>
</div>

Performance Comparison

Here’s a simple performance comparison using JavaScript:

// Traditional SPA approach
const loadFullApp = () => {
  // Loads entire application
  import('./app').then(app => app.init());
}

// Astro's approach
const loadIsland = () => {
  // Loads only what's needed
  import('./component').then(comp => comp.mount());
}

The difference in initial JavaScript payload can be significant!
