# react-native-showdown [![Dependency Status][dependency-image]][dependency-url]



[React-native](http://facebook.github.io/react-native/) component which renders markdown into a webview!



Since version 1.0.0 it requires the peer dependency [react-native-webview](https://github.com/react-native-community/react-native-webview).



## Features



* Renders Markdown into a React Native WebView component.

* Pure JavaScript implementation, based on [Showdown](https://github.com/showdownjs/showdown),

  extendable with all (?) [Showdown Extensions](https://github.com/showdownjs/showdown/wiki/Extensions).

* No native code / No react-native link required.

* Customizable with CSS.

* Full TypeScript Support.

* Fully tested. 100% Code Coverage.

* ~~Automatically opens links in the system browser.~~ Supports all React Native WebView props and callbacks!



## Installation



```bash

npm install --save react-native-showdown react-native-webview

```



or



```bash

yarn add react-native-showdown react-native-webview

```



With expo you are done.



With a pure React Native project you need to link react-native-webview:



```bash

react-native link react-native-webview

cd pods && pod install && cd ..

```



## Usage



Full ES6 / TypeScript example:



```jsx

import React from 'react';

import Markdown from 'react-native-showdown';

import { SafeAreaView } from 'react-native';



export default function App() {

  const markdown = `

# Welcome to React Native Showdown!



To get started, edit the markdown in \`App.tsx\`.



| Column 1 | Column 2 |

|----------|----------|

| A1       | B1       |

| A2       | B2       |

`;



  const css = `

h1 { color: red; }

code { font-size: 1.2rem; background-color: lightgray; }

`;



  return (

    

      

    

  );

}

```



## Available props / converter options



* `markdown` String, required;

  Markdown string which will be shown as webview content.

  (Previous prop `body` is also still supported as fallback.)

* `css` String, optional;

  CSS which will be used to style the webview content.

  (Previous prop `pureCSS` is also still supported as fallback.)

* `title` String, optional;

  Sets the HTML title tag.

* `options` ConverterOptions, optional;

  All [Showdown#options](https://github.com/showdownjs/showdown#valid-options). 

  Default is `{simplifiedAutoLink: true, strikethrough: true, tables: true}`.

* All other [react-native-webview](https://github.com/react-native-community/react-native-webview)

  [props](https://github.com/react-native-community/react-native-webview/blob/master/docs/Reference.md#props-index) and callbacks are also supported, expect the `source` prop!

* Notice that the WebView has a default `{ flex: 1 }` style defined.



## Run the example



```bash

git clone https://github.com/jerolimov/react-native-showdown.git

cd react-native-showdown

yarn install

yarn bootstrap   # which is similar to   cd example && yarn install



cd example
