Failed to instantiate module maq - angularjs

Question

I can't figure out what I'm doing wrong here.
//app.js
'use strict';
var app = angular.module('maq', [
'ui.router',
'maq.home.controller'
]).run([
'$rootScope',
'$state',
'$stateParams', function($rootScope, $state, $stateParams){
$rootScope.$state = $state;
$rootScope.$stateParams = $stateParams;
}])
.config([
'$stateProvider',
'$urlRouterProvider', function($stateProvider, $urlRouterProvider){
$urlRouterProvider.otherwise('/');
$stateProvider
.state('home', {
url: '/',
templateUrl: 'views/home.html',
controller: 'maq.home.controller'
})
}]);
//controller
'use strict';
app
.controller('maq.home.controller', [function(){
}]);
//error
Uncaught Error: [$injector:modulerr] Failed to instantiate module maq due to:
Error: [$injector:modulerr] Failed to instantiate module maq.home.controller due to:
Error: [$injector:nomod] Module 'maq.home.controller' is not available! You either misspelled the module name or forgot to load it. If registering a module ensure that you specify the dependencies as the second argument.

Answer 1

You actually do not have a module called maq.home.controller Instead your registration is in such a way that it is the controller name.
If you want to separate your controller to another module (as what you are trying to do)
try:-
angular.module('maq.controller', []); //<-- Module creation
//...
angular.module('maq.controller')
.controller('HomeController', [function() { //<-- Controller registration
}]);
and in your app:-
var app = angular.module('maq', [
'ui.router',
'maq.controller' //<-- Controller mmodule
]);
Or just remove the dependency on the module that does not exist:-
angular.module('maq', [
'ui.router',
//'maq.home.controller' <-- Remove this
])

Answer 2

You are trying to depend on another module named maq.home.controller when it is not a module, it is a controller. You do not need to list controllers as dependencies in your module declaration. So just take that dependency out like so:
var app = angular.module('maq', [
'ui.router'
])
