react-native-web: React Native (Web) components not resolving

Do you want to request a feature or report a bug? Bug (possibly?)

What is the current behavior? I’m following the documentation at https://github.com/necolas/react-native-web/blob/master/website/guides/getting-started.md#web-packaging-for-existing-react-native-apps and using the webpack.config there as a template. I’m not sure if react-native-web is replacing react-native properly. It can’t resolve basic components such as ActivityIndicator.

./node_modules/.bin/webpack-dev-server -d --config ./web/webpack.config.js --inline --hot --colors

The relevant changes to the webpack.config (I placed it under the web/ subdir):

const babelLoaderConfiguration = {
  test: /\.js$/,
  // Add every directory that needs to be compiled by Babel during the build.
  include: [
    path.resolve(appDirectory, 'web/index.web.js'),
    path.resolve(appDirectory, 'app'),
    // ... other node_modules packages
  ],
  use: {
    loader: 'babel-loader',
    options: {
      cacheDirectory: true,
      // Babel configuration (or use .babelrc)
      // This aliases 'react-native' to 'react-native-web' and includes only
      // the modules needed by the app.
      plugins: ['react-native-web'],
      // The 'react-native' preset is recommended to match React Native's packager
      presets: ['react-native']
    }
  }
};

Dependencies babel-core, babel-loader, babel-plugin-react-native-web, babel-preset-react-native, babel-preset-react-native-stage-0, babel-preset-stage-0, react-dom, react-native-web are installed. I’m stumped!

What is the expected behavior?

No errors 😃
