🔑 Key Features
Astro offers a variety of features that make it a powerful tool for front-end development:
Zero JavaScript by Default
Astro's unique approach is to deliver minimal JavaScript by default. This means that unless you explicitly include JavaScript, your site will be static HTML, resulting in faster load times and better performance.
Component Agnostic
Astro allows you to use components from your favorite frameworks together in a single project. Whether you prefer React, Vue, Svelte, or any other framework, Astro has you covered.
Island Architecture
Astro introduces the concept of "islands" where JavaScript is only loaded for specific interactive parts of the page. This ensures that your site remains fast while still providing a rich user experience.
Built-In Optimizations
Astro comes with a range of built-in optimizations, including automatic image optimization, CSS minification, and more. These features help ensure that your site performs well out of the box.
🚀 Building a Simple Project
Let's walk through building a simple Astro project to see these features in action.
Step 1: Create a New Page

// src/pages/index.astro
---
import HelloWorld from '../components/HelloWorld.astro';
---
<html lang="en">
<head>
<title>My Astro Site</title>
</head>
<body>
<h1>Welcome to Astro!</h1>
<HelloWorld />
</body>
</html>
Step 2: Create a Component
Create a new component in the src/components directory:
// src/components/HelloWorld.astro
---
export const prerender = true;
---
<p>Hello, world! This is an Astro component.</p>
Step 3: Run the Development Server
Start the development server to see your site in action:
npm start
Visit http://localhost:3000 to see your new Astro site!
