Accessing the app module in separate files is not possible for Angular and Coffeescript

Question

Accessing the app module in separate files is not possible for Angular and Coffeescript

As I work on managing and refactoring my Angular code in a Rails project with CoffeeScript, I am facing issues accessing Angular objects between multiple files. Here is the current file structure:

javascripts
|-Angular
  |-controllers
  | |-search_strl.js.coffee
  |-main.js.coffee
|-application.js

In application.js: //= require_tree ./angular

In main.js.coffee:


'use strict'; 
copassApp = angular.module 'copassApp', []

In search_ctrl:

copassApp.controller('SearchCtrl', ['$scope', 'Cospace', 'Copasser', '$location', ($scope, Cospace, Copasser, $location) -> ...more code...

Console error: Uncaught ReferenceError: copassApp is not defined

I'm unsure if this issue stems from a missing required file or a problem with how I've structured my Angular module and CoffeeScript setup across files. Any guidance would be appreciated.

Edit

After implementing the suggested solution, here is the compiled JS:

main.js.coffee:

(function() {
  'use strict';
  var copassApp, root;

  copassApp = angular.module('copassApp', ['copassApp.SearchCtrl']);
  root = $('html');
  angular.bootstrap(root, ['copassApp']);
}).call(this);

search_strl.js.coffee:

(function() {
  angular.module('copassApp.SearchCtrl', ['$scope', 'Cospace', 'Copasser', '$location', function($scope, Cospace, Copasser, $location) {}]);
}).call(this);

When troubleshooting javascript code, it is important to consider the loading order of your scripts. One common issue could be that search_ctrl.js is loading before main.js, causing errors. It is also advisable to avoid declaring global variables and instead utilize angular.module() in separate files to access existing modules.

If we were to translate this code snippet into plain javascript, it might look like:

main.js:

(function() {
  'use strict';
  var copassApp = angular.module('copassApp', []);
})();

search_ctrl.js:

(function() {
  'use strict';
  angular.module('copassApp').controller('SearchCtrl', function($scope)) {
    ...more code...
  });
})();

Remember, it is crucial for main.js to load before search_ctrl.js.

Alternatively, you can use separate modules and require them in main.js to ensure file loading order does not pose an issue.

main.js:

(function() {
  'use strict';
  var copassApp = angular.module('copassApp', ['copassApp.SearchCtrl']);
})();

search_ctrl.js:

(function() {
  'use strict';
  angular.module('copassApp.SearchCtrl', []).controller('SearchCtrl', function($scope)) {
    ...more code...
  });
})();

Everything is now functioning correctly. I want to express gratitude to @theJoeBiz for helping me correct my previous code that was not properly structured. Although my file structure remains the same, here are the updated files:

main.js.coffee:

copassApp = angular.module 'Copass', ['Factories', 'Controllers', 'Directives']
factories = angular.module 'Factories', ['Cospace', 'Copasser', 'HtmlViewService']
...

search_ctrl.js.coffee

angular.module('Search', []).controller('Search', [... ->

I initially misunderstood angular.module as a getter and setter, but it is actually only for initialization purposes. Hopefully this clears up any confusion for others as well.
