Getting Started with Astro: A Modern Static Site Generator

Astro has quickly become one of the most popular static site generators in the web development community. In this post, we’ll explore why Astro is gaining so much traction and how you can get started with it.

What is Astro?

Astro is a modern static site generator that allows you to build faster websites using your favorite JavaScript frameworks. It’s designed with a “content-first” mindset and introduces an innovative “Islands Architecture” that helps deliver exceptional performance out of the box.

Key Features

1. Component Islands

One of Astro’s most distinctive features is its component islands architecture. This approach allows you to:

  • Ship zero JavaScript by default
  • Hydrate only the interactive components
  • Keep the rest of your site as static HTML
  • Achieve incredible performance metrics

2. Framework Agnostic

With Astro, you can:

  • Use React, Vue, Svelte, or any other framework
  • Mix and match different frameworks in the same project
  • Write components in pure HTML and CSS if you prefer

3. Built-in Performance

Astro automatically:

  • Bundles and minifies your JavaScript
  • Optimizes your images
  • Inlines critical CSS
  • Removes unused CSS

Getting Started

Here’s how to create your first Astro project:

# Create a new project with npm
npm create astro@latest

# Navigate to your project
cd your-project-name

# Install dependencies
npm install

# Start the development server
npm run dev

Project Structure

Creating Your First Page

---

<html lang="en">
  <head>
    <title>My First Page</title>
  </head>
  <body>
    <h1>{greeting}</h1>
