React Native Web Extended

"React Native Web Extended" is a fork of React Native Web, with more components migrated from React Native.

Patch for React Native Web is available in the patch/react-native-web branch.

Get Started

Install using npm:

npm install react-native-web-extended --save

Boilerplate is coming soon.

Extended components

Currently 3 more components from React Native are added.

Navigator

Navigator from React Native is re-implemented with react-router.

Usage:

render() {
  const routes = [
    {index: 0, title: 'Page 1'},
    {index: 1, title: 'Page 2'},
  ];
  return (
    <Navigator
      initialRoute={routes[0]}
      renderScene={(route, navigator) =>
        <TouchableHighlight onPress={() => {
          if (route.index === 0) {
            navigator.push(routes[1]);
          } else {
            navigator.pop();
          }
        }}>
        <Text>Hello! Route index is {route.index}, title is {route.title}</Text>
        </TouchableHighlight>
      }
      style={{padding: 100}}
    />
  );
}

Note:

• Currently supported props: initialRoute, renderScene.
• index key in the route object is required.
• initialRouteStack prop is not supported, as we can't push multiple history states when the webpage loads.

TabBarIOS

Usage:

'use strict';

var React = require('react');
var ReactNative = require('react-native');
var {
  StyleSheet,
  TabBarIOS,
  Text,
  View,
} = ReactNative;

var base64Icon = 'data:image/png;base64,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';
