Astro Static Site Generator

Deploy multilingual static websites for free on Cloudflare using Astro framework.

Prerequisites

• Node.js 20+ installed
• Cloudflare account (free)
• Git repository (GitHub, GitLab, or Bitbucket)

Quick Start

1. Create Project

npm create astro@latest my-site -- --template minimal
cd my-site
npm install

2. Configure for Cloudflare

Static Sites (Recommended for most use cases)

No adapter needed. Use default static output:

// astro.config.mjs
import { defineConfig } from 'astro/config';

export default defineConfig({
  site: 'https://your-site.pages.dev',
});

SSR/Edge Functions (Optional)

If you need server-side rendering or edge functions:

npm install @astrojs/cloudflare

// astro.config.mjs
import { defineConfig } from 'astro/config';
import cloudflare from '@astrojs/cloudflare';

export default defineConfig({
  output: 'server',
  adapter: cloudflare(),
  site: 'https://your-site.pages.dev',
});

3. Deploy to Cloudflare

Git Integration (Recommended)

1. Push to GitHub/GitLab
2. Cloudflare Dashboard → Pages → Create project → Connect to Git
3. Configure:
   • Build command: npm run build
   • Build output: dist

Direct Upload

# Deploy (authenticate via Cloudflare dashboard or wrangler)
npx wrangler pages deploy dist

Multilingual Configuration

Astro Config

// astro.config.mjs
export default defineConfig({
  i18n: {
    defaultLocale: 'en',
    locales: ['en', 'es', 'fr', 'de'],
    routing: {
      prefixDefaultLocale: false,  // /about instead of /en/about
    },
  },
});

Routing Modes:

Content Structure

src/content/
├── config.ts          # Content collection schema
└── docs/
    ├── en/
    │   ├── index.md
    │   └── guide.md
    ├── es/
    │   ├── index.md
    │   └── guide.md
    └── fr/
        ├── index.md
        └── guide.md

Content Collection Schema

// src/content/config.ts
import { defineCollection, z } from 'astro:content';

const docs = defineCollection({
  type: 'content',
  schema: z.object({
    title: z.string(),
    description: z.string(),
    lang: z.enum(['en', 'es', 'fr', 'de']),
  }),
});

export const collections = { docs };

Note: Run npx astro sync after adding content collections to generate types.

Language Switcher Component

---
// src/components/LanguageSwitcher.astro
const languages = {
  en: 'English',
  es: 'Español',
  fr: 'Français',
  de: 'Deutsch',
};

const currentPath = Astro.url.pathname;
const currentLang = Astro.currentLocale || 'en';
---

<select = this.value">
  {Object.entries(languages).map(([code, name]) => (
    <option 
      value={`/${code}${currentPath}`} 
      selected={code === currentLang}
    >
      {name}
    </option>
  ))}
</select>

Cloudflare Pages Settings

/old-page  /new-page  301

Commands Reference

Blog with Content Collections

---
// src/pages/blog/[...slug].astro
import { getCollection } from 'astro:content';

export async function getStaticPaths() {
  const posts = await getCollection('blog');
  return posts.map(post => ({
    params: { slug: post.slug },
    props: { post },
  }));
}

const { post } = Astro.props;
const { Content } = await post.render();
---

<article>
  <h1>{post.data.title}</h1>
  <Content />
</article>

Troubleshooting

Build Fails on Cloudflare

Set NODE_VERSION=20 in Cloudflare Pages environment variables.

404 on Nested Routes

// astro.config.mjs
export default defineConfig({
  trailingSlash: 'always',
});

i18n Not Working

Ensure:

1. Locales match folder names exactly
2. Content files have correct lang frontmatter
3. Run npx astro sync after creating content collections

Content Collection Type Errors

Run npx astro sync to generate TypeScript types.
