The order of execution in AngularJS: Understanding the flow

I have taken over the responsibility of managing someone else's website, and while going through the codebase, I came across a snippet that looks like the one below (with some code omitted for simplicity):

    var Application = (function ($, global) {
    'use strict';
    global.site = global.site || {};
    global.site.App = App;

    function App() {
       // code removed
    }

    App.getState = function () {
        return 'standard';
    };

    App.setState = function () {
        // Set current state on load
        site.App.currentState = site.App.getState();
    };

    //a lot of code was removed

    return {
        init:function(){

            global.site.app = new global.site.App();

            // Set browser sate on load
            site.App.setState();
            console.log('Application: site.App.currentState', site.App.currentState);  
        }
    }

}(window.jQuery, window));

$(Application.init);

var siteApp = angular.module('siteApp', []);
siteApp.controller('AppController', function() {
      console.log('AppController: site.App.currentState', site.App.currentState);
});

My main issue is that the angularjs module is executing before the

var Application = (function ($, global) {...}(window.jQuery, window));
line, which I need to run first. Since I'm not fully familiar with the design pattern used in (Application.init) , I have the following questions:

  1. How can I ensure that $(Application.init); runs before anything else?
  2. What type of design pattern is being used in (Application.init), so I can research and understand it better?

Any assistance or guidance on this matter would be greatly appreciated.

Answer №1

If you want to experiment, consider eliminating

$(Application.init)

and instead directly invoking

Application.init() 

Answer №2

A) The code provided is needlessly complex and could benefit from being refactored into an Angular service, value, or factory.

B) For better code organization, consider removing the ng-app="App" directive and manually bootstrapping Angular like so:

angular.element(document).ready(function () {
    Application.init();
    angular.bootstrap(document, ['App']);
}

C) The code demonstrates the use of the module pattern, as discussed in this article: http://example.com/mastering-the-module-pattern
