react-hot-loader incompatible with react 15.4.1

In watch mode react pack throws Module not found: Error: Cannot resolve module 'react/lib/ReactMount' to fix this you can add an alias to webpack config like so:

    resolve: {
        alias: { 'react/lib/ReactMount': 'react-dom/lib/ReactMount' }
    }
