React Native Markdown Renderer

Is a 100% compatible CommonMark renderer, a react-native markdown renderer done right. This is not a web-view markdown renderer but a renderer that uses native components for all its elements. These components can be overwritten when needed as seen in the examples.

To give a summary of the supported syntax react-native-markdown-renderer supports.

• Tables
• Heading 1 > 6
• Horizontal Rules
• Typographic replacements
• Emphasis ( bold, italic, ~~strikethrough~~ )
• Blockquotes
• Lists
  • Ordered
  57. Unordered
  58. foo
  59. bar
• Code Blocks
• Syntax highlighting
• Links
• Images
• Plugins for extra syntax support, see plugins. Because this markdown-renderer uses markdown-it as its base it also supports all its plugins and subsequent extra language support.

tested on:

| [] | react | react-native | | ---- | ---- | ------- | | v | 16.0.0-alpha.12 | 0.45.1 | | v | 16.0.0-alpha.6 | 0.44.0 | | v | ^15.6.1 | ^0.46.4 |

todo

• add styleSheet support
• add styleSheet inheritance support
• ~~adding plugin support~~

How to:

npm

npm install -S react-native-markdown-renderer

yarn

yarn add react-native-markdown-renderer

Example:

Simple example

import react from 'react';
import {View, PureComponent} from 'react-native';
import Markdown from 'react-native-markdown-renderer';

const copy = `# h1 Heading 8-)

| Option | Description |
| ------ | ----------- |
| data   | path to data files to supply the data that will be passed into templates. |
| engine | engine to be used for processing templates. Handlebars is the default. |
| ext    | extension to be used for dest files. |
`;

export default class Page extends PureComponent {

  static propTypes = {};
  static defaultProps = {};

  render() {

    return (
    	<Markdown>{copy}</Markdown>
    );
  }
}

If you want to use your own native elements and styling, and want to add extra plugins:

import react from 'react';
import {View, PureComponent, Text} from 'react-native';
import Markdown, { AstRenderer, defaultRenderFunctions, PluginContainer, blockPlugin} from 'react-native-markdown-renderer';

const copy = `# h1 Heading 8-)

| Option | Description |
| ------ | ----------- |
| data   | path to data files to supply the data that will be passed into templates. |
| engine | engine to be used for processing templates. Handlebars is the default. |
| ext    | extension to be used for dest files. |

[block]
I'm in a block
[/block]
`;

/**
 * i'm overriding the default h1 render function.
 */
const renderer = new AstRenderer({
  ...defaultRenderFunctions,
  h1: (node, children, parents) => {
    return <Text style={{backgroundColor: 'red'}}>{children}</Text>;
  },
  // added custom block element defined by plugin
  block: (node, children, parents) => {
  	return <Text style={{backgroundColor: 'green'}}>{children}</Text>;
  }
});

export default class Page extends PureComponent {

  static propTypes = {};
  static defaultProps = {};

  render() {

  	const plugins = [
  	  new PluginContainer(blockPlugin, 'block', {})
  	];

    return (
    	<Markdown renderer={renderer} plugins={plugins}>{copy}</Markdown>
    );
  }
}

Emphasis

~~Strikethrough~~

Blockquotes

Blockquotes can also be nested...

...by using additional greater-than signs right next to each other...

...or with spaces between arrows.

Lists

Unordered

• Create a list by starting a line with +, -, or *
• Sub-lists are made by indenting 2 spaces:
  • Marker character change forces new list start:
    • Ac tristique libero volutpat at
    • Facilisis in pretium nisl aliquet
    • Nulla volutpat aliquam velit
• Very easy!

Ordered

1. Lorem ipsum dolor sit amet

2. Consectetur adipiscing elit

3. Integer molestie lorem at massa

4. You can use sequential numbers...

5. ...or keep all the numbers as 1.

Start numbering with offset:

57. foo
58. bar

Code

Inline code

Indented code

// Some comments
line 1 of code
line 2 of code
line 3 of code

Block code "fences"

Syntax highlighting

var foo = function (bar) {
  return bar++;
};
