- Now we will detect what javascript engine user is using and based on that we will generate either `.js` or `.coffee` version of the channel file. - This also needs a change in coffee-rails to override the `js_template` method. Related PR https://github.com/rails/coffee-rails/pull/72. - Currently coffee-rails gem sets `config.app_generators.javascript_engine` to `:coffee` and using this information we override the `js_template` to set the extension as `.coffee` in coffee-rails gem. - Using this approach, we can keep the `channel.js` and `channel.coffee` files in the Rails repository itself. - Additionally the `js_template` method can act as public interface for coffee-rails gem to hook into and change the extension to `.coffee` without maintaining the actual asset files.
