The origins of the project began with the need to do a rich JavaScript interface for a ShakaCode's client. The choice to use Webpack and Rails is described in Fast Rich Client Rails Development With Webpack and the ES6 Transpiler.
The gem project started with Justin Gordon pairing with Samnang Chhun to figure out how to do server rendering with Webpack plus Rails. Alex Fedoseev then joined in. Rob Wise, Aaron Van Bokhoven, and Andy Wang did the bulk of the generators. Many others have contributed.
The gem was initially inspired by the react-rails gem.
