Rails - activate javascript

Question

Is there any chance to display a precompiled javascript file? A simple file has no problems with:

def iframe_communication
  render file: "/app/assets/javascripts/iframe_communication_module.js"
end

I tried assets_pathor included it in javascript_include_tagthe view, but failed.

For clarification, I do not want to add a script to my view. I am trying to display a javascript file for external access (tagging <script>from other domains).

Refresh

• render file: "..." shows file as expected but not compiled version
• assets_path "/app/assets/javascripts/iframe_communication_module.js"returns "/app/assets/javascripts/iframe_communication_module.js", not the path to the compiled resource
• javascript_include_tag loads the script as expected (no rendering)

The Rails 4 resource pipeline compiles everything into a single file, is there any chance of getting one file from it?
Or is this the best way to compile it manually?

this: assets_path , . :

asset_path "application.js" # => /application.js  
asset_path "application", type: :javascript # => /javascripts/application.js

apps/assets/javascript/application.js.

config.assets.precompile += %w( iframe_communication_module.js )
