Environment Variables in JS/Coffeescript

Question

Is there anyway I can get an environment variable (like an API key) to appear inside JS/Coffee using Rails 3.1?

The given answer is good, but you can also set a global JS variable from your view like (HAML): :javascript \n window.API_KEY = '#{ENV['API_KEY']}'; — Chloe

You can rename your file.js to file.js.erb and use ruby to access ENV:

<% do_something_with ENV['key'] %>
some_js_code

Should work if properly named. See guides.rubyonrails.org/… section 2.2.3
