Injecting a controller into an AngularJS module within an anonymous function

Injecting a controller into an AngularJS module within an anonymous function

As a newcomer to the world of javascript and just beginning to work with angular.js, I have a question.

I'm wondering if there is a method for injecting a controller into a module that is declared within an anonymous function.

This is how my code currently appears:

app.js

(function(angular) {
    var app = angular.module('Organizer', ['ngMaterial', 'ngAnimate', 'ngAria']);
})(angular);

siteController.js

(function(angular, app) {
    app.controller('site', function($scope, $mdDialog)
    {
        var alert = $mdDialog.alert({
            title: 'Test',
            content: 'Testing',
            ok: 'Exit'
        });

        $mdDialog.show(alert);
    });
})(angular);

I've attempted to find solutions on whether this is possible, but I am eager to hear explanations from anyone here who may know how to achieve this.

Note: While I have previous experience with angular.js, I wanted to explore a different approach for declaring controllers in order to prevent client modifications.

If you develop a module using Angular, it cannot be obscured in this manner. Users can easily access your app by running angular.module('Organizer') in the console and then executing any desired method.

The issue with your code not functioning as intended is due to the lack of passing the app variable to your unnamed function. To add a controller to the Organizer module, you should follow this pattern:

(function(angular)
{
    angular.
      module('Organizer').
      controller('site', function($scope, $mdDialog)
      {
          ...
      });
})(angular);

There is no necessity to enclose any of this code within self-executing functions in an attempt to prevent variables from polluting the global scope. The sole global object is "angular".

Your app.js file should contain only:

'use strict';
angular.module('Organizer', ['ngMaterial', 'ngAnimate', 'ngAria']);

Your controller file should contain only:

'use strict';
angular.module('Organizer').controller('siteController', function($scope, $mdDialog) {
    var alert = $mdDialog.alert({
        title: 'Test',
        content: 'Testing',
        ok: 'Exit'
    });

    $mdDialog.show(alert);
});

The initial call to module in app.js includes the second parameter that angular utilizes for instantiating your module. Any subsequent calls that do not include the second parameter "retrieve" the module.
