Introduction to Astro

Astro is a modern static site builder that delivers lightning-fast performance with a modern developer experience. Unlike traditional JavaScript frameworks, Astro ships zero JavaScript by default, resulting in incredibly fast page loads.

Why Choose Astro?

**Zero JavaScript by default**: Astro strips away unused JavaScript, shipping only HTML and CSS

**Framework agnostic**: Use React, Vue, Svelte, or any framework you prefer

**Islands Architecture**: Interactive components only hydrate when needed

**Content-focused**: Perfect for blogs, documentation, and portfolio sites

Setting Up Your First Project

Getting started with Astro is straightforward. Open your terminal and run:

```bash

npm create astro@latest my-blog

cd my-blog

npm run dev

```

This will scaffold a new Astro project with all the essential files and configurations.

Project Structure

```

my-blog/

├── src/

│ ├── components/

│ ├── layouts/

│ ├── pages/

│ └── styles/

├── public/

├── astro.config.mjs

└── package.json

```

Creating Your First Page

Astro uses file-based routing. Create a file in the `src/pages/` directory, and it automatically becomes a route:

```astro

---

// src/pages/index.astro

import Layout from '../layouts/Layout.astro'

const title = "My First Astro Blog"

---

Welcome to My Blog

This is my first Astro page!

```

Working with Components

Astro components are reusable UI units. Here's how to create a blog card component:

```astro

---

// src/components/BlogCard.astro

interface Props {

title: string

excerpt: string

date: string

}

const { title, excerpt, date } = Astro.props

---

{title}

{excerpt}

{date}

```

Deploying Your Site

Astro sites can be deployed to various platforms:

**Vercel**: `npm run build` outputs static files

**Netlify**: Drag and drop the `dist/` folder

**GitHub Pages**: Use GitHub Actions for automatic deployment

Conclusion

Astro provides an excellent balance between developer experience and performance. By shipping less JavaScript and focusing on content, your websites load faster and provide better user experiences.
