Adding web to an existing React Native project

If you already have a React Native project and want to add web support, you need to execute the following commands in your existing project directory:

Install npm install react-web-cli -g
Execute react-web init <ExistedProjectDir>. That install react-web and devDependencies to your project and make a web directory with webpack.config.js file under your project
Register your app into a web platform. To do so, add the code from Fix platform differences. 2. Should run application on web platform to your index.ios.js file
Execute npm start
Execute react-web start that starts the web dev server
Execute react-web bundle that builds the output

Getting Started

Install

npm install react-web --save

Add Webpack configuration

Inside your webpack configuration, alias the react-native package to the react-web package, then install and add haste-resolver-webpack-plugin plugin.

// webpack.config.js
var HasteResolverPlugin = require('haste-resolver-webpack-plugin');

module.exports = {
  resolve: {
    alias: {
      'react-native': 'react-web'
    }
  },
  plugins: [
    new HasteResolverPlugin({
      platform: 'web',
      nodeModules: ['react-web']
    })
  ]
}

See more detail of the webpack.config.js from React Native Web Example

What does HasteResolverPlugin do?

When using components of react-web, just require('ReactActivityIndicator'), and Webpack will build a bundle with ActivityIndicator.web.js for web platform.

HasteResolverPlugin will do the following for you:

Walk over all components and check out the @providesModule info.
When webpack build bundle, it makes your components recognised rather than throwing an error.
It will help webpack build bundle with correct file depending on the tar* platform.

You can find something like @providesModule ReactActivityIndicator on react-web component's comment, yes, it's for HasteResolverPlugin.

Require modules

The CommonJS way

var React = require('react-native');
var {
  AppRegistry,
  StyleSheet,
  View,
  Platform,
} = React;

This reference method looks like we're in the way of using the native react-native way:

Like the require module in Node.js, and through Destructuring assignment, allows some components to be referenced in the scope of the current file.

But in fact it is quite different in React Web. When require('react-native'), in the construction of the webpack will be renamed, equivalent to require('react-web').

At the same time, this form of writing will put all the components into at one time, including ReactAppRegistry ReactView and so on, even some components the you did not use.

The Haste way

var AppRegistry = require('ReactAppRegistry');
var View = require('ReactView');
var Text = require('ReactText');
var Platform = require('ReactPlatform');

In this way, we load our components on demand, such as ReactAppRegistry or ReactView and so on.

Packaged components so that we no longer need to care about the differences between the platform.

As mentioned above, the HasteResolverPlugin plugin will help webpack to compile and package the code.

Fix platform differences

Native events without direct pageX/pageY on web platform

if (Platform.OS == 'web') {
  var touch = event.nativeEvent.changedTouches[0];
  pageX = touch.pageX;
  pageY = touch.pageY;
} else {
  startX = event.nativeEvent.pageX;
  startY = event.nativeEvent.pageY;
}

Should run application on web platform

AppRegistry.registerComponent('Game2048', () => Game2048);
if(Platform.OS == 'web'){
  var app = document.createElement('div');
  document.body.appendChild(app);
  AppRegistry.runApplication('Game2048', {
    rootTag: app
  })
}

Should care about fetch domain on web platform

var fetch = Platform.OS === 'web'? require('ReactJsonp'): require('ReactFetch');

Without some APIs like LayoutAnimation on web platform

var LayoutAnimation = require('ReactLayoutAnimation')
if(Platform.OS !== 'web'){
  LayoutAnimation.configureNext(...)
}

Should manually specify the height of ScrollView

<ScrollView style={{height: 235}} horizontal={true} />
