Injecting Dependencies in config() modules - AngularJS

Question

Currently in app.js i have the following routes:

var gm = angular.module(\'gm\', [\'gm.services\',\'gm.directives\',\'gm.filters\',\'gm.controllers\',\'ngSan

1. angular.config only accepts Providers
2. every service, factory etc are instances of Provider

So to inject a service in config you just need to call the Provider of the service by adding 'Provider' to it's name.

angular.module('myApp')
  .service('FooService', function(){
    //...etc
  })
  .config(function(FooServiceProvider){
    //...etc
  });

According to the angularjs Provider documentation

... if you define a Factory recipe, an empty Provider type with the $get method set to your factory function is automatically created under the hood.

So if you have a factory (or service) such as:

.factory('myConfig', function(){
  return {
    hello: function(msg){
      console.log('hello ' + msg)
    }
  }
})

You first need to invoke your factory using the $get method before accessing the returned object:

.config(function(myConfigProvider){
   myConfigProvider
     .$get()
     .hello('world');
});
