Astro Usage Guide
Always consult docs.astro.build for code examples and latest API.
Astro is the web framework for content-driven websites.
Quick Reference
File Location
CLI looks for astro.config.js, astro.config.mjs, astro.config.cjs, and astro.config.ts in: ./. Use --config for custom path.
CLI Commands
npx astro dev - Start the development server.npx astro build - Build your project and write it to disk.npx astro check - Check your project for errors.npx astro add - Add an integration.npx astro sync - Generate TypeScript types for all Astro modules.
Re-run after adding/changing plugins.
Project Structure
Reference project structure docs.
src/* - Project source code (components, pages, styles, images, etc.)src/pages - Required. Defines all pages and routes.src/components - Components (convention, not required).src/layouts - Layout components (convention, not required).src/styles - CSS/Sass files (convention, not required).public/* - Non-code, unprocessed assets (fonts, icons, etc.); copied as-is to build output.package.json - Project manifest.astro.config.{js,mjs,cjs,ts} - Astro configuration file. (recommended)tsconfig.json - TypeScript configuration file. (recommended)
Core Config Options
| Option | Notes |
|---|
site | Your final, deployed URL. Used to generate sitemaps and canonical URLs. |
Example astro.config.ts
import { defineConfig } from "astro/config";
export default defineConfig({
site: "https://example.com",
});
Common Workflows
Creating a Basic Page
Add a file to src/pages/ — the filename becomes the route:
---
// src/pages/index.astro
const title = "Hello, Astro!";
---
<html>
<head><title>{title}</title></head>
<body>
<h1>{title}</h1>
</body>
</html>
Creating a Component
---
// src/components/Card.astro
const { title, body } = Astro.props;
---
<div class="card">
<h2>{title}</h2>
<p>{body}</p>
</div>
Deploying with an Adapter
- Add the adapter:
npx astro add vercel --yes (or node, cloudflare, netlify)
- Run
npx astro check to catch type and configuration errors before building.
- Run
npx astro build to produce the deployment artifact.
- Verify the build output directory (e.g.
dist/) exists and is non-empty before proceeding.
- Deploy the output per the adapter's documentation.
Adapters
Deploy to your favorite server, serverless, or edge host with build adapters. Use an adapter to enable on-demand rendering in your Astro project.
Add Node.js adapter using astro add:
npx astro add node --yes
Add Cloudflare adapter using astro add:
npx astro add cloudflare --yes
Add Netlify adapter using astro add:
npx astro add netlify --yes
Add Vercel adapter using astro add:
npx astro add vercel --yes
