angularjs - Injecting a Angular service into controller results in $injector:unpr error (using AngularBooter) -

i using angularbooter angular in app.

here code:

emp.boot();  emp.services.socialservice = ['$http', '$q', function ($http, $q) {      var deferred = $q.defer();      $http.get('/api/feed').then(function (data) {         deferred.resolve(data);     });      this.getstatuses = function ()     {         return deferred.promise;     }  }];  emp.controllers.statusescontroller = ['$scope','socialservice', '$interval',  function($scope, socialservice, $interval) {      var statuses = socialservice.getstatuses();      statuses.then(function(data) {         $scope.statuses = data;         console.log($scope.statuses);     }); }]; 

from understand error: error: [$injector:unpr] sign service isn't being registered or implemented correctly, have tried few things keep running same problem. ideas.

two problems:

1) booting before register stuff (at least in code provided). emp.boot() right @ bottom after has been defined.

2) service not returning anything. instance, if add return {}; @ bottom of service function, should magically not throw error anymore, want return more interesting that.

you can see in action uncommenting line returns object , see angular start working again. http://codepen.io/alex-wilmer/pen/qbwngz?editors=101

i imagine want this:

emp.services.socialservice = ['$http', '$q', function ($http, $q) {   var deferred = $q.defer();    $http.get('/api/feed').then(function (data) {     deferred.resolve(data);   });    return {     getstatuses = function () { // don't mix brace placement!       return deferred.promise;     }   }; }];
