Getting Started

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

# This is the title of my deck

---

# About Me

---

```jsx
<CodeSnippet />
```

---

import Demo from './components/Demo'

## <Demo />

# The end

Add a run script to your package.json with the mdx-deck CLI pointing to the .mdx file to start the dev server:

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

Start the dev server:

npm start

Quick Start

To create a new presentation with zero-configuration, run the following command to generate a presentation deck in a new folder:

npm init deck my-presentation-name

Using MDX

MDX can use Markdown syntax and render React components with JSX.

Imports

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

import { Box } from 'grid-styled'

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

Read more about MDX syntax in the MDX Docs.

Theming

mdx-deck uses styled-components for styling, making practically any part of the presentation themeable.

Built-in Themes

mdx-deck includes several built-in themes to change the look and feel of the presentation. Export theme from your MDX file to enable a theme.

export { dark as theme } from 'mdx-deck/themes'

# Dark Theme

MDX uses exports as a way for files to communicate with their parent components. For a list of available themes see the Themes Docs.

Custom Themes

A custom theme can be provided by exporting theme from the MDX file.

export { default as theme } from './theme'

# Hello

The theme should be an object with fields for fonts, colors, and CSS for individual components. It's recommended that all custom themes extend the default theme as a base.

// example theme.js
import theme from 'mdx-deck/themes'

export default {
  // extends the default theme
  ...theme,
  // add a custom font
  font: 'Roboto, sans-serif',
  // custom colors
  colors: {
    text: '#f0f',
    background: 'black',
    link: '#0ff',
  },
}

Read more about theming in the Theming docs

Components

mdx-deck includes built-in components to help with creating presentations, including a full screen Image component, the Appear component that allows stepping through parts of a single slide, and the Notes component for adding speaker notes.

Read more in the components docs.

Libraries

These third-party libraries are great 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.

Layouts

Each slide can include a custom layout around its content. This can be used as a substitute for slide templates found in other presentation apps and libraries.

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

export default ({ children }) => (
  <div
    style={{
      width: '100vw',
      height: '100vw',
      backgroundColor: 'tomato',
    }}>
    {children}
  </div>
)

import Layout from './Layout'

# No Layout

---

export default Layout

# Custom Layout

The layout component will wrap the MDX elements within that slide, which means you can use a nested ThemeProvider or target elements with CSS-in-JS.

Built-in Layouts

mdx-deck includes some built-in layouts for inverting theme colors and changing the layout of a slide. Read more about built-in layouts.

Presenter Mode

mdx-deck includes a built-in presenter mode, with a preview of the next slide and a timer.

To use presenter mode:

• Open two windows in the same browser, with the same URL on two different screens. (this should work in both development and exported presentations)
• In your window, press the Option/Alt + P keys (or add ?mode=presenter to the URL) to enter presenter mode.
• Display the other window on the screen for the audience to see.
• Control the presentation from your window by using the left and right arrow keys; the other window should stay in sync

Speaker Notes

Notes that only show in presenter mode can be added to any slide. Speaker notes can be added in one of the following two ways:

Markdown: Use the notes language attribute in a fenced code block to add speaker notes.

# Slide Content

```notes
These are only visible in presenter mode
```

Notes Component: Use the Notes component to create more complex speaker notes.

import { Notes } from 'mdx-deck'

# Slide Content

<Notes>Only visible in presenter mode</Notes>

Overview Mode

When editing a slide deck, toggle overview mode with Option + O or add ?mode=overview to the URL. This shows a list of all slides on the left and a preview of the current slide on the right.

Keyboard Shortcuts

Key	Description
Left Arrow	Go to previous slide (or step in Appear)
Right Arrow	Go to next slide (or step in Appear)
Space	Go to next slide (or step in Appear)
Up Arrow	Hide current step in Appear component without navigating slides
Down Arrow	Show next step in Appear component without navigating slides
Option + P	Toggle Presenter Mode
Option + O	Toggle Overview Mode
Option + G	Toggle grid view mode

Exporting

Add a build script to your package.json to export a presentation as HTML with a JS bundle.

"scripts": {
  "build": "mdx-deck build deck.mdx"
}

See more exporting options in the Exporting Documentation
