I have a module that has a service defined as
angular.module('mean.system').service('helperService', ['$rootScope', '$q', '$log', function ($rootScope, $q, $log) {
I am defining another module that will use the same service. I want to inject this service into another module, is it valid to do something like
angular.module('mean.system', 'myModule2').service('helperService', ... (etc) ) {
