Why I Migrated to Astro for My Blog

After years of using Jekyll for my blog, I recently migrated to Astro. Here’s why I made the switch and what I learned along the way.

The Problem with Jekyll

Don’t get me wrong—Jekyll is great. But I found myself running into a few issues:

• Ruby dependency management was becoming a pain
• Build times were getting slower as my site grew
• I wanted to use modern JavaScript tooling
• Limited flexibility for interactive components

Why Astro?

Astro caught my attention for several reasons:

1. Zero JavaScript by Default

Astro ships zero JavaScript to the client by default. This means blazing-fast page loads:

---
// This runs at build time, not in the browser
const posts = await fetchPosts();
---

<ul>
  {posts.map(post => (
    <li>{post.title}</li>
  ))}
</ul>

2. Component Islands

When you do need interactivity, Astro’s island architecture is brilliant:

---
import Counter from '../components/Counter.jsx';
---

<div>
  <h1>Static content</h1>
  <Counter client:load />
</div>

3. Bring Your Own Framework

You can use React, Vue, Svelte, or any framework you like—or mix them:

---
import ReactComponent from './React.jsx';
import VueComponent from './Vue.vue';
---

<ReactComponent />
<VueComponent />

4. Content Collections

Astro’s content collections provide type-safe content management:

import { defineCollection, z } from 'astro:content';

const blog = defineCollection({
  schema: z.object({
    title: z.string(),
    date: z.date(),
    tags: z.array(z.string())
  })
});

Migration Process

The migration was surprisingly smooth:

1. Set up a new Astro project
2. Converted Liquid templates to Astro components
3. Moved markdown files (minimal changes needed)
4. Updated frontmatter to match new schema
5. Deployed to Cloudflare Pages

Results

After migration:

• Build time: 45s → 8s (5.6x faster)
• Page load: 2.1s → 0.4s (5.2x faster)
• Lighthouse score: 87 → 100

Conclusion

Migrating to Astro was one of the best decisions I’ve made for my blog. The performance improvements alone were worth it, but the developer experience is what keeps me excited about building with it.

If you’re considering a static site generator for your next project, give Astro a try!
