angularjs - Issues with Firebase Auth.$requireAuth() -

so reading on firebase's "user authentication" section find way stop un-authenticated users accessing specific pages (i.e. when they're not logged in)

the solution came across, use snipet of code:

resolve: {       // controller not loaded until $requireauth resolves       // auth refers our $firebaseauth wrapper in example above       'currentauth': ['auth', function(auth) {         // $requireauth returns promise resolve waits complete         // if promise rejected, throw $statechangeerror (see above)         return auth.$requireauth();       }]     } 

so after put in , tried access specific page without being logged in, got following error message in console:

error: [$injector:unpr] unknown provider: authprovider <- auth <- currentauth 

if try log in after words, unable navigate specific page.

i've been searching around few hours find solution , people said dependency issue not having "ngroute" included in app.js file. have dependency included know that's not issue.

angular   .module('app', [     'nganimate',     'ngcookies',     'ngresource',     'ngroute',     'ngsanitize',     'ngtouch',     'ui.sortable',     'firebase',     'angular-toarrayfilter'   ])   .constant('fb', {     url: 'https://<url>.firebaseio.com/'   })   .factory('firebaseref', function(fb) {     return new firebase(fb.url);   })   .factory('userauth', function($firebaseauth, firebaseref){     return $firebaseauth(firebaseref);   })   .config(function ($routeprovider) {     $routeprovider       .when('/', {         templateurl: 'views/login.html',         controller: 'loginctrl',         controlleras: 'login_controller'       })       .when('/view_resources', {         templateurl: 'views/view_resources.html',         controller: 'viewresourcesctrl',         controlleras: 'view_resources',         resolve: {           // controller not loaded until $requireauth resolves           // auth refers our $firebaseauth wrapper in example above           'currentauth': ['auth', function(auth) {             // $requireauth returns promise resolve waits complete             // if promise rejected, throw $statechangeerror (see above)             return auth.$requireauth();           }]         }       })       .otherwise({         redirectto: '/'       });   }); 

thanks time.

i think factory

.factory('userauth', function($firebaseauth, firebaseref){     return $firebaseauth(firebaseref);   }) 

should named "auth" follow:

.factory('auth', function($firebaseauth, firebaseref){     return $firebaseauth(firebaseref);   })
