Rails 4 + Sprockets: Allowing the use of js.erb files

I am attempting to use ES6 syntax in my Rails 4 app and have had some success between the use of sprockets-es6 (0.9.2), sprockets-rails (3.0.4) and sprockets (3.6.0).

The only issue I'm having is that my files need to end in .es6 in order to enable proper compilation and I'd like to be able to use a .es6.erb or .js.erb file type to allow me to use embedded ruby <%= foo %>.

Does anyone know of a way around this?

This question is a few years old and the OP specifies Sprockets 3.6. But I'm guessing many will find this question when looking for a solution to using erb files with a more modern version of sprockets.

If you're using Sprockets 4 and want to use .js.erb you'll need to 'register_mime_type'.

e.g. add the following to a new file called ./config/initializer/register_mime_type.rb

Sprockets.register_mime_type 'application/javascript', extensions: ['.js.erb']

This is described in Extending Sprockets.
