@astrojs/mdx: What It Is and How It Works in Astro

@astrojs/mdx is an official Astro integration that lets you use MDX files in your Astro projects. MDX combines Markdown with JSX, allowing you to write content with embedded React components inside your Markdown files.

How It Works

@astrojs/mdx acts like a translator between Markdown and Astro components. It lets you write your content in Markdown but also embed interactive components written in JSX, like buttons or custom layouts. Think of it as writing a story (Markdown) where you can drop in pictures or widgets (JSX components) exactly where you want.

When you build your Astro site, this integration processes the MDX files and converts them into Astro components. This means your Markdown content and React components work together seamlessly, making your pages dynamic and easy to maintain.

Example

This example shows an MDX file using Markdown and a React button component inside Astro.

mdx

import { Button } from '../components/Button.jsx';

# Welcome to My Blog

This is a paragraph written in Markdown.

<Button>Click Me!</Button>

Output

<h1>Welcome to My Blog</h1>
<p>This is a paragraph written in Markdown.</p>
<button>Click Me!</button>

When to Use

Use @astrojs/mdx when you want to write content with Markdown but also need interactive or custom components inside that content. It's perfect for blogs, documentation, or marketing pages where you want simple text mixed with buttons, forms, or other UI elements.

For example, if you want to add a signup form or a special call-to-action button inside your blog posts without leaving Markdown, this integration makes it easy and clean.
