Getting Started with Astro: A Modern Web Framework
Astro is a modern web framework that allows you to build fast, content-focused websites. It’s designed to give you the best of both worlds: the performance of static sites with the flexibility of dynamic applications.
Why Choose Astro?
Astro stands out from other frameworks for several key reasons:
1. Performance First
Astro ships zero JavaScript by default, resulting in incredibly fast loading times. Only the JavaScript you actually need gets sent to the browser.
2. Component Islands
You can use any UI framework (React, Vue, Svelte, etc.) as “islands” within your Astro pages, giving you the flexibility to choose the right tool for each component.
3. Content-Focused
Built specifically for content-heavy websites like blogs, documentation sites, and marketing pages.
Setting Up Your First Astro Project
Let’s walk through creating a new Astro project:
# Create a new project
npm create astro@latest my-astro-site
# Navigate to the project
cd my-astro-site
# Install dependencies
npm install
# Start the development server
npm run devProject Structure
A typical Astro project has the following structure:
my-astro-site/
├── src/
│ ├── components/
│ ├── layouts/
│ ├── pages/
│ └── content/
├── public/
├── astro.config.mjs
└── package.jsonCreating Your First Page
In Astro, pages are created in the src/pages/ directory. Here’s a simple example:
---
// Frontmatter goes here
const title = 'Hello, Astro!';
---
<html lang="en">
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width" />
<title>{title}</title>
</head>
<body>
<h1>{title}</h1>
<p>Welcome to your first Astro page!</p>
</body>
</html>Using Components
Components in Astro use the .astro extension and can be used in any page:
---
// src/components/Header.astro
const { title } = Astro.props;
---
<header>
<h1>{title}</h1>
<nav>
<a href="/">Home</a>
<a href="/about">About</a>
<a href="/contact">Contact</a>
</nav>
</header>Content Collections
Astro’s content collections provide type-safe content management:
// src/content/config.ts
import { defineCollection, z } from 'astro:content';
const blog = defineCollection({
schema: z.object({
title: z.string(),
author: z.string(),
publishDate: z.date(),
}),
});
export const collections = { blog };Deployment
Astro sites can be deployed to any static hosting service:
- Netlify : Automatic deployments from Git
- Vercel : Optimized for Astro projects
- GitHub Pages : Free hosting for open source projects
