Generate, configure, and deploy content-driven websites using the Astro web framework.

  • Build components, manage routes, and set up static site generation for content projects.
  • Interacts with the Astro CLI and project structure, including `astro.config.js`.
  • Detects mentions of `.astro` files, SSG, islands architecture, or deployment needs.
  • Provides command execution guidance and structural advice for the development workflow.

# Astro Usage Guide

**Always consult [docs.astro.build](https://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](https://docs.astro.build/en/basics/project-structure).

- `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`

```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:

```astro
---
// src/pages/index.astro
const title = 'Hello, Astro!';
---
<html>
  <head><title>{title}</title></head>
  <body>
    <h1>{title}</h1>
  </body>
</html>
```

### Creating a Component

```astro
---
// src/components/Card.astro
const { title, body } = Astro.props;
---
<div class="card">
  <h2>{title}</h2>
  <p>{body}</p>
</div>
```

### Deploying with an Adapter

1. Add the adapter: `npx astro add vercel --yes` (or `node`, `cloudflare`, `netlify`)
2. Run `npx astro check` to catch type and configuration errors before building.
3. Run `npx astro build` to produce the deployment artifact.
4. Verify the build output directory (e.g. `dist/`) exists and is non-empty before proceeding.
5. 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](https://docs.astro.build/en/guides/integrations-guide/node) adapter using astro add:**
```
npx astro add node --yes
```

**Add [Cloudflare](https://docs.astro.build/en/guides/integrations-guide/cloudflare) adapter using astro add:**
```
npx astro add cloudflare --yes
```

**Add [Netlify](https://docs.astro.build/en/guides/integrations-guide/netlify) adapter using astro add:**
```
npx astro add netlify --yes
```

**Add [Vercel](https://docs.astro.build/en/guides/integrations-guide/vercel) adapter using astro add:**
```
npx astro add vercel --yes
```
