React Rails
Integrate React.js with Rails views and controllers
...Therefore the pre-bundled version of react no longer has an addons version, if you need addons still, there is the 2.3.1+ version of the gem that still has addons. React-Rails supports plenty of file extensions such as: .js, .jsx.js, .js.jsx, .es6.js, .coffee, etcetera! Sometimes this will cause a stumble when searching for filenames. The require.context inserted into packs/application.js is used to load components. The component name tells react-rails where to load the component.
