Why MDX?

MDX is a special flavor of Markdown that supports embedded JavaScript & JSX syntax. This unlocks the ability to mix JavaScript and UI Components into your Markdown content for things like interactive charts or alerts.

If you have existing content authored in MDX, this integration will hopefully make migrating to Astro a breeze.

Example

Here is how you import and use a UI component inside of MDX. When you open this page in the browser, you should see the clickable button below.
