Entry Points and Globally Exposing Objects

You should ensure you configure the entry points correctly for webpack.

When using React 0.14 and greater

You need both include react-dom/server and react as values for entry, like this:

  entry: {

    // See use of 'vendor' in the CommonsChunkPlugin inclusion below.
    vendor: [
      'babel-core/polyfill',
      'react',
      'react-dom',
    ],

and you need to expose them:

      // React is necessary for the client rendering:
      {test: require.resolve('react'), loader: 'expose?React'},
      {test: require.resolve('react-dom'), loader: 'expose?ReactDOM'},

and use this line rather than {test: require.resolve('react-dom'), loader: 'expose?ReactDOM'},:

   {test: require.resolve('react-dom/server'), loader: 'expose?ReactDOMServer'},

When you use React 0.13

You don't need to put in react-dom.
