WebView #

WebView renders web content in a native view.

import React, { Component } from 'react'; import { WebView } from 'react-native'; class MyWeb extends Component { render() { return ( <WebView source={{uri: 'https://github.com/facebook/react-native'}} style={{marginTop: 20}} /> ); } }

You can use this component to navigate back and forth in the web view's history and configure various properties for the web content.
