Getting Started

npm i -D mdx-deck

Create an MDX file and separate each slide with ---.

# Hello


## This is my deck


## The End

Add a run script to your package.json with the MDX Deck CLI pointing to the .mdx file to start the development server:

"scripts": {
  "start": "mdx-deck deck.mdx"

Start the development server:

npm start

Use the left and right arrow keys to navigate through the presentation.

Using MDX

MDX uses Markdown syntax and can render React components inline with JSX.


To import components, use ES import syntax separated with empty lines between any markdown or JSX syntax.

import { Box } from 'theme-ui'

<Box color="tomato">Hello</Box>

Read more about MDX syntax in the MDX Docs.


MDX Deck uses Theme UI and Emotion for styling, making practically any part of the presentation themeable. It also includes several built-in themes to change the look and feel of the presentation.


MDX Deck includes built-in components to help with creating presentations, a Notes component for adding speaker notes, a Head component for the document head, Header and Footer components for persistent header and footer content, and a Steps component for adding multiple intermediate steps in a single slide.

Read more in the Components docs.

Third-Party Components

These optional libraries are intended for use with MDX Deck.

  • CodeSurfer: React component for scrolling, zooming and highlighting code.
  • mdx-code: Runnable code playgrounds for MDX Deck.
  • mdx-deck-live-code: Live React and JS coding in slides.

Note: please check with version compatibility when using these libraries.


Each slide can include a custom layout around its content, which can be used as a template for visually differentiating slides.

// example Layout.js
import React from 'react'

export default ({ children }) => (
      width: '100vw',
      height: '100vh',
      backgroundColor: 'tomato',
import Layout from './Layout'

# No Layout



# Custom Layout


The layout component will wrap the MDX elements within that slide, which means you can add custom layout styles or style child elements with CSS-in-JS.

Presenter Mode

Press Option + P to toggle Presenter Mode, which will show a preview of the next slide, a timer, and speaker notes.
