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 notifications, and export metadata. This makes writing long-form content with components a blast. 🚀

See MDX in action:

import { Chart } from '../components/chart'

# Heres a chart

The chart is rendered inside our MDX document.

<Chart />


MDX is markdown for the component era. It lets you write JSX embedded inside markdown. That’s a great combination because it allows you to use markdown’s often terse syntax (such as # heading) for the little things and JSX for more advanced components.

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

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

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

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

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

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 […] is extremely useful for using design system components to render markdown and weaving interactive components in with existing markdown.”


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. A nice example of this is mdx-deck, a great way to create slides with MDX.
