将JavaScript转换为Coffee？

Question

In a Rails project with only a Coffee file, can I add a JavaScript file?

If not, am I supposed to convert each JavaScript file to Coffee?

Answer 1

You may use both JavaScript and Coffee files side-by-side in a Rails 3/4 app.

Coffee files are just a convenience. They are all compiled to browser-compatible JavaScript files when the application is run.

So, using a JavaScript file is acceptable. The Asset pipeline will know how to handle both appropriately.

This depends on the 'coffee-rails' gem being present in your Gemfile.
