javascript - typescript + angular: factory with dependencies error -

i'm migrating angular app typescript. i've got following ts code:

/// <reference path="../../../typings/tsd.d.ts" />  class uiroutinghelper {   constructor(public $state: any) {};    reloadcurrentview() {     return this.$state.go(this.$state.current.name, this.$state.params, {       reload: true     });   }; }  mp.core.coremodule.factory('uiroutinghelper', ['$state', uiroutinghelper]); 

which compiles correctly. whole application build process builds correctly well. in runtime following error:

error: [$injector:undef] provider 'uiroutinghelper' must return value $get factory method. http://errors.angularjs.org/1.3.15/$injector/undef?p0=uiroutinghelper     @ angular.js:63     @ object.enforcedreturnvalue [as $get] (angular.js:4058)     @ object.invoke (angular.js:4203)     @ angular.js:4021     @ getservice (angular.js:4162)     @ object.invoke (angular.js:4194)     @ extend.instance (angular.js:8493)     @ angular.js:7739     @ foreach (angular.js:331)     @ nodelinkfn (angular.js:7738) 

please advice me on doing wrong.

typings//tsd.d.ts bootstrap file, loads predefined interfaces. mp.core.coremodule has been declared before (it's available typescript).

don't use factory class. use service. code:

class uiroutinghelper {   constructor(public $state: any) {};    reloadcurrentview() {     return this.$state.go(this.$state.current.name, this.$state.params, {       reload: true     });   }; }  mp.core.coremodule.service('uiroutinghelper', ['$state', uiroutinghelper]);
