Rails Javascript compression/minification on respond_to javascript response?

Question

Greetings Rails and Javascript Gurus!

I have a project where I am returning a large javascript file in a

respond_to do |format|
   format.js
end

block.

I am trying to figure out how I can minify or compress the .js response since the .js.erb view is full of comments and varies in size based on the results from the controller.

Anyone have any ideas?

For Rails 4:

render js: Uglifier.new.compile(render_to_string)
