React Web 中文 npm version

A framework for building web apps with React.



Web Examples

Open with mobile device or emulate mobile in developer tools

Example Source


npm install react-web --save


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:

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

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

Require modules

Two ways to require modules.

The CommonJS way

var React = require('react-native');
var {
} = 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

  1. 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;
  2. Should run application on web platform

    AppRegistry.registerComponent('Game2048', () => Game2048);
    if(Platform.OS == 'web'){
    var app = document.createElement('div');
    AppRegistry.runApplication('Game2048', {
      rootTag: app
  3. Should care about fetch domain on web platform

    var fetch = Platform.OS === 'web'? require('ReactJsonp'): require('ReactFetch');
  4. Component without setNativeProps method on web platform

    var setNativeProps = require('ReactSetNativeProps')
    setNativeProps(, {
    style: {
      top: 0
  5. Without LayoutAnimation on web platform

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


  • Linting - npm run lint - Must run it before commit.
  • Testing - npm test - Run unit testing by jest.
  • Developing - npm start - This will run a server at localhost:3000 and use Hot Module Reloading.
  • Demo deployment - npm run demo - Generate demo assets under pages directory.
