# Getting Started with Astro Content Collections

Astro Content Collections provide a **type-safe** way to manage your content files. Let's explore how they work!

## What are Content Collections?

Content Collections are directories of content files that Astro:

- ✅ Validates your frontmatter against a schema
- ✅ Provides TypeScript types for your content
- ✅ Enables performance optimizations
- ✅ Supports various file formats (MD, MDX, JSON)

## Example Frontmatter

The frontmatter of this file is automatically validated:

<Code code={`---
title: "Getting Started with Astro Content Collections"
description: "Learn how to use Astro's Content Collections"
pubDate: 2024-01-15
tags: ["astro", "content-collections"]
---`} />

## Working with Collections

You can query collections in your Astro pages:

\```astro
---
import { getCollection } from 'astro:content';

const posts = await getCollection('blog', ({ data }) => {
  return !data.draft && data.pubDate <= new Date();
});

const featuredPosts = posts.filter(post => post.data.featured);
---

<h1>Featured Posts</h1>
{featuredPosts.map(post => <article>{post.data.title}</article>)}
\```

## Benefits

1. **Type Safety**: Catch errors at build time
2. **Performance**: Optimized content loading
3. **Developer Experience**: Autocomplete and validation
4. **Flexibility**: Support for multiple content types

*Happy coding with Astro! 🚀*
