Is it okay to change the loading order of JavaScript files in Rails 4?

In my application.js.coffee I define some overarching functions which I use in my other JavaScript files. So far this was no problem, because except in application.js.coffee most of the code was wrapped in document ready $ ->

Now I am optimizing loading time, for instance running AJAX requests outside of $ -> to start the data loading beforehand.

Now I need the functions I have defined, which are of course not available since application.js.coffee is loaded at the very end. To solve this I replaced

 #= require_tree .

with

 #= require_self
 #= require_tree .

Is this the way to do it, or is that proscribed?

That's how it's usually done. You'd have to require application.js.coffee before requiring your other custom javascript files(which are loaded with require_tree). Make sure though that application.js.coffee's plugin dependencies are loaded before the require_self.

For example, if you use jQuery, you'd do it this way in your application.js.coffee 

#= require jquery
#= require_self
#= require_tree .
