Uses Webpack to bundle files and serves it with webpack-dev-server.

Commands:

• npm start is the development target, and will serves the app on port 3000.
• npm run build is the production target, to create the final bundle.

Remarks:

• In a real application you would likely want to add things like hot reloading for development and a minification step etc to the production build step etc.
• These steps have been omitted here in order to keep the example as simple as possible.
