Building a Modern Blog with Astro

Astro is an ideal framework for content-focused websites. Thanks to its zero JavaScript by default approach, it delivers flawless performance.

Why Astro?

What sets Astro apart from other frameworks:

1. Zero JS by default: Your pages are served as pure HTML
2. Island Architecture: Only the interactive parts load JS
3. Content Collections: Type-safe content management
4. Multi-framework support: React, Vue, and Svelte can be used together

Project Setup

Creating a new Astro project is very simple:

npm create astro@latest my-blog
cd my-blog
npm install
npm run dev

Content Collections

One of Astro’s most powerful features is Content Collections:

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

const blog = defineCollection({
  loader: glob({ pattern: '**/*.mdx', base: './src/content/blog' }),
  schema: z.object({
    title: z.string(),
    description: z.string(),
    publishDate: z.coerce.date(),
    tags: z.array(z.string()),
  }),
});

export const collections = { blog };

With this structure, all your content is validated at build time.

Deploying to Cloudflare Pages

To deploy your Astro project to Cloudflare Pages:

1. Push to GitHub
2. Create a new Pages project in the Cloudflare Dashboard
3. Set the build command to npm run build
4. Specify the build output directory as dist

# wrangler.toml
name = "my-blog"
pages_build_output_dir = "./dist"
