Markdown for the component era

MDX is a format that lets you seamlessly use JSX in your Markdown documents. You can import components, like interactive charts or notifs, and export metadata. This makes writing long-form content with components a blast πŸš€.

Hello, world!

Here's an example of the Rebass Donut rendered inside an MDX document.

❀️ Powerful: MDX blends markdown and JSX syntax to fit perfectly in React/JSX-based projects.

πŸ’» Everything is a component: Use existing components inside your MDX and import other MDX files as plain components.

πŸ”§ Customizable: Decide which component is rendered for each markdown element ({ h1: MyHeading }).

πŸ“š Markdown-based: The simplicity and elegance of markdown remains, you interleave JSX only when you want to.

πŸ”₯ Blazingly blazing fast: MDX has no runtime, all compilation occurs during the build stage.

β€œIt’s extremely useful for using design system components to render markdown and weaving interactive components in with existing markdown.”

Before MDX, some of the benefits of writing Markdown were lost when integrating with JSX. Implementations were often template string-based which required lots of escaping and cumbersome syntax.

MDX seeks to make writing with Markdown and JSX simpler while being more expressive. The possibilities are endless when you combine components (that can even be dynamic or load data) with the simplicity of Markdown for long-form content.
