AngularJS Question

AngularJS - getting "Uncaught Error: [$injector:modulerr]" message on a simple app

I'm following along with Linkster's online tutorial that shows how to make a reddit clone using the MEAN stack. (https://thinkster.io/mean-stack-tutorial#angular-routing)

I've gotten to a point where I've tried everything, but nothing seems to be working. Any ideas what's wrong? Any help/ideas are appreciated :)

var app = angular.module('flapperNews', ['ui-router']);
app.config([
'$stateProvider',
'$urlRouterProvider',
function($stateProvider, $urlRouterProvider){

$stateProvider
.state ('home', {
url: "/home",

// .state('posts', {
// url: '/posts/{id}',
// templateUrl: '/posts.html',
// controller: 'PostsCtrl'
// });

$urlRouterProvider.otherwise('home');
}])

app.factory('posts', [function(){
var o = {
posts: [{title: 'hello post1', link: '', upvotes: 0 }]
};
return o;
}])

app.controller('MainCtrl', [
'$scope',
'posts',
function($scope, posts){
$scope.test = 'Hello world!';

$scope.posts = posts.posts;

$scope.addPost = function(){
if(!$scope.title || $scope.title === '') { return; }
$scope.posts.push({
title: $scope.title,
link: $scope.link,
upvotes: 0});
$scope.title = '';
$scope.link = '';
}

$scope.incrementUpvotes = function(post) {
post.upvotes += 1;
}
}]);

Answer

Try var app = angular.module('flapperNews', ['ui.router']); instead of var app = angular.module('flapperNews', ['ui-router']);
