To access javascript files from another application

I am trying to access my precompiled files of my application from another. I have a specific architecture. Here is a simplified tree

├── app
│   ├── assets
│   │   ├── javascripts
│   │   │   ├── application.coffee
│   │   │   ├── my_js_file.coffee
├── my-other-app
│   ├── index.html
│   ├── javascript
│   │   ├── anotherJSFile.js

I would like to upload to a index.htmlcompiled file my_js_file.coffee.

my-other-appnot a Rails application. It contains a base file index.htmlthat redirects to a specific url where I try something like:

<script src="http://myapp.com/assets/my_js_file.js"></script>

I defined it in the configuration file Apache(this part is fine).

My problem is that I cannot find a way to access the compiled file my_js_file.js. Access to the file and the file name itself (with a fingerprint). How can i solve this?

Edit: , , , url .
