ReactJS setup (unique CSS)

Once you have ejected the project, edit the webpack.config.dev.js file. Search for test: /\.css$/. Under the the use >> options property add the following under the importLoaders: 1,:

modules: true,
localIdentName: '[name]__[local]__[hash:base64:5]'

This allows for setting up unique CSS class names when multiple components are used that might use a similarly named CSS class style.
