# mdx-deck

[MDX][]-based presention decks

**Beta**

```sh
npm i mdx-deck
```

- :spiral_note_pad: Write presentations in markdown
- :atom_symbol: Import and use React components
- :nail_care: Customizable themes and components
- :zero: Zero-config CLI

## Getting Started

Create an [MDX][] file and separate each slide with `---`.

````mdx
# This is the title of my deck
---
# About Me
---
```jsx
<CodeSnippet />
```
---
import Demo from './components/Demo'

<Demo />
---
# The end
````

Run the CLI pointing to the `.mdx` file to start the dev server:

```sh
mdx-deck deck.mdx
```

## 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.

```mdx
import { Box } from 'grid-styled'

<Box color='tomato'>
  Hello
</Box>
```

### Theming

mdx-deck uses [styled-components][] for styling.

### Built-in Themes

mdx-deck includes several built-in themes to change the look and feel of the presentation.

```mdx
export { dark as theme } from 'ok-cli/themes'

# Dark Theme
```

The following themes are available:

- `theme`: default theme with white background
- `dark`: black background dark theme
- `future`: dark theme with Avenir Next
- `condensed`: dark theme with Roboto Condensed

### Custom Themes

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

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

# Hello
```

The theme should be an object based on [styled-system][]'s theme schema.

```js
// example theme.js
export default {
  font: 'Georgia',
  monospace: 'Menlo, monospace',
  fontSizes: [
    16, 24, 32, 48, 64, 96, 128
  ],
  colors: {
    text: '#000',
    background: 'transparent',
    link: '#07c',
    heading: '#000',
    quote: '#000',
    pre: '#f0f',
    preBackground: '#333',
    code: '#f0f',
    codeBackground: 'transparent',
  },
  css: {
    // apply any styles to the root element
  },
  // custom CSS can be provided to any of the default components:
  heading: {
    fontWeight: 400
  },
  link: {
    textDecoration: 'none',
    '&:hover': {
      textDecoration: 'underline',
    }
  }
}
```

### Custom Components

mdx-deck includes default components for MDX, but to provide custom components to the [MDXProvider][], export a `components` object.

```mdx
export { default as components } from './components'

# Custom Components
```

### Layouts

Each slide can include a custom layout around its content.

```mdx
import Layout from './Layout'

# No Layout

---
export default Layout

# Custom Layout
```

### Custom Provider

A custom Provider component can be exported to wrap the entire application.
This is useful for adding custom context providers, such as a ThemeProvider.

```mdx
export { default as Provider } from './Provider'

# Hello
```

## Exporting

Run the `build` command to export a presentation as HTML with a JS bundle.

```sh
mdx-deck build deck.mdx
```

## React API

mdx-deck components can also be used in any React application, such as [create-react-app][] or [next.js][].

### Webpack Loader

mdx-deck uses a custom webpack loader to split MDX files into an array of slides. Use this loader to import mdx files in a webpack application.

```js
// example webpack.config.js
module.exports = {
  module: {
    rules: [
      {
        test: /\.mdx$/,
        ignore: /node_modules/,
        use: [
          'babel-loader',
          'mdx-deck/loader'
        ]
      }
    ]
  }
}
```

### SlideDeck Component

```js
import React from 'react'
import { SlideDeck } from 'mdx-deck'
import slides from './deck.mdx'
import theme from './theme'
import components from './components'

export default () =>
  <SlideDeck
    slides={slides}
    theme={theme}
    components={components}
    width='100vw'
    height='100vh'
  />
```
