Getting an AngularJS Service Undefined error is frustrating. The message "Unknown provider: $scopeProvider <- $scope"

I've recently delved into learning Angular JS and encountered an issue when trying to inject a service into a controller. My aim is to incorporate the ThreadFactory service into the ThreadController, however, I am facing an undefined error upon calling it. Any assistance would be greatly appreciated. The error message reads as follows:

Unknown provider: $scopeProvider <- $scope <- ThreadService

app.js

angular.module('threadsApp', ['ngRoute']);
angular.module('threadsApp')
    .config(function ($routeProvider, $locationProvider) {
        $routeProvider
            .when('/', {
                templateUrl: 'views/index.html',
            })
            .when('/selected/:topicName', {
                templateUrl: 'views/threads.html',
                controller: 'ThreadController',
            })
            .otherwise({
                redirectTo: "/"
            });
            $locationProvider.html5Mode(true);
    });

ThreadController.js

angular.module('threadsApp').controller("ThreadController",
    ["$scope", "$route", "$routeParams", "ThreadService", function ($scope, $route, $routeParams, ThreadService) {
    $scope.test = "Hello!";
    $scope.test2 = ThreadService.get();
}]);

ThreadService.js

angular.module('threadsApp').service("ThreadService", ["$scope", function ($scope) {
    return {
        get: function() {
            return "Hello";
        }
    }
}]);

Answer №1

Attempting to inject $scope into your ThreadService is not the correct approach. $scope does not function as a typical service when injected into a controller. By removing the $scope injection from Threadservice.js, you may resolve the error.

To avoid repetition, a more detailed explanation can be found at:
