Add React With Webpacker To A New Rails App

Webpacker makes it easy to manage app-like JavaScript in the context of a Rails app. React is a great candidate for this kind of webpack-powered JavaScript processing pipeline.

To set up a new Rails project with Webpack and React wired up, add the --webpack=react flag:

$ rails new rails-react-app --webpack=react

As part of the generated app, you will get a app/javascript/packs directory with a hello_react.jsx file that has a really basic React component.
