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

Video Tutorial

For a video introduction, see this egghead tutorial by @andrewdelprete.

Usage

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>

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.

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 + P (Alt + P) key 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>

Keyboard Shortcuts

Key	Description
Left Arrow	Go to previous slide
Right Arrow	Go to next slide
Space	Go to next slide
Option + P	Toggle Presenter Mode
Up Arrow	Hide current step in Appear component
Down Arrow	Show next step in Appear component

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"
}

PDF Export

Presentations can be exported as PDF using the CLI. This works well as a backup option for any unforeseen technical difficulties.

"script": {
  "pdf": "mdx-deck pdf deck.mdx"
}

CLI Options

-p --port     Dev server port
--no-open     Prevent from opening in default browser
-d --out-dir  Output directory for exporting
--title       Title for the HTML document
