react-native-markdown-package

Node Module Package for implementing markdown syntax in React Native. I knew this is not a perfect library, so your contribution, Pull Request, or anything else from you guys will be really appreciated. :)

Getting started

To install this library, you can do in two different ways. Check this out :

1. Run this command in your project folder.

   npm i react-native-markdown-package --save

2. OR Update manually your dependencies in package.json by adding this following line, afterwards run npm install 

   "react-native-markdown-package": "git+https://github.com/andangrd/react-native-markdown-package.git"

Usage

What you need to do is import the react-native-markdown-package module and then use the <Markdown/> tag.

How to use?

Here we are, take a look at this simple implementation:

/**
 * Sample React Native App
 * https://github.com/facebook/react-native
 * @flow
 */

import React, { Component } from 'react';
import Markdown from 'react-native-markdown-package';
import {
  AppRegistry,
  StyleSheet,
  Text,
  View
} from 'react-native';

export default class AwesomeProject extends Component {
  render() {
    return (
      <View style={styles.container}>
        <Text style={styles.welcome}>
          Welcome to React Native!
        </Text>
        <Markdown styles={styles.markdown} >
          # This is Heading 1{'\n\n'}
          ## This is Heading 2{'\n\n'}
          1. List1 {'\n'}
          2. List2 {'\n'} 
          {'\t'}1. sublist1{'\n'}
          {'\t'}description sublist1.{'\n'}
          {'\t'}2. sublist2{'\t\t'}{'\n'}
          * List3{'\n'}
          * List4{'\n'}
          {'\t'}1. **bold text** {'\n'}
          {'\t'}2. this line contain * and should not be a new sublist{'\t\t'}{'\n'}
          5.  Last list{'\n\n'}
          Some *really* basic **Markdown**.{'\n\n'}


          ## this is header {'\n\n\n\n'}
          {'this is _italic_ '}
          {'this is **strong**'}

          {'\n\n'}
          | # | Name   | Age |{'\n'}
          |---|--------|-----|{'\n'}
          | 1 | John   | 19  |{'\n'}
          | 2 | Sally  | 18  |{'\n'}
          | 3 | Stream | 20  |{'\n'}
        </Markdown>
      </View>
    );
  }
}

const styles = {
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    backgroundColor: '#F5FCFF',
  },
  welcome: {
    fontSize: 20,
    textAlign: 'center',
    margin: 10,
  },
  instructions: {
    textAlign: 'center',
    color: '#333333',
    marginBottom: 5,
  },
  markdown: {
    heading1: {
      color: 'red'
    },
    heading2: {
      color: 'green'
    },
    strong: {
      color: 'blue'
    },
    em: {
      color: 'cyan'
    },
    text: {
      color: 'magenta',
    }
  }
};

AppRegistry.registerComponent('AwesomeProject', () => AwesomeProject);

Properties

styles

Default style properties will be applied to the markdown. You will likely want to customize these styles, the following properties can be used to modify the rendered elements:

Note: The text inside the parentheses denotes the element type.

• autolink (<Text>) - WIP
• blockQuote (<Text>) - WIP
• br (<Text>)
• codeBlock (<View>) - WIP
• del (<Text>)
• em (<Text>)
• heading (<Text>) - Also heading1 through heading6
• hr (<View>)
• image (<Image>) - Implemented but size is fixed to 50x50 until auto width is supported by React Native.
• inlineCode (<Text>)
• link (<Text>) - WIP
• list (<View>) - Also sublist (<View>), listItem (<View>), listItemBullet (<Text>) and listItemNumber (<Text>)
• sublist (<View) - Also listItem (<View>), listItemBullet (<Text>) and listItemNumber (<Text>)
• mailto (<Text>) - WIP
• newline (<Text>) - WIP
• paragraph (<View>)
• plainText (<Text>) - Use for styling text without any associated styles
• strong (<Text>)
• table (<View>)
• tableHeader (<View>)
• tableHeaderCell (<Text>)
• tableRow (<View>)
• tableRowCell (<View>)
• tableRowLast (<View>, inherits from tableRow)
• text (<Text>) - Inherited by all text based elements
• u (<View>)
• url (<Text>)
• view (<View>) - This is the container View that the Markdown is rendered in.

Thanks To

this project was actually forked from lwansbrough , gijoehosaphat and imported a parser library which forked from Khan with some enhancements below :

1. Styling method.

   Now you can easily add styling on each syntax, e.g. add different color either in strong, header, or another md syntax. All default styles in this package is also already moved to new file styles.js.

2. Refactoring some codes to adopt ES6 style.

   Refactor index.js using ES6. :)

3. Support Sublist.

   In the previous library, you couldn't add sublist. It was not supported. But now, this feature already added here. Please follow the instruction above...

4. Latest release, add Proptypes Support.

Happy Coding... ;)
