AngularJS module doesn't work - javascript

So I've been looking at this for way too long. Really hope someone could help me out :) I'm just trying to create a module that creates a directive and controller for my site header in AngularJS. I don't get any error and the log in my code won't show up. This is the code related to the header module:
header/header.js
'use strict';
angular.module('myApp.header', [])
.directive("headerBar", [function(){
return {
restric: "E",
templateUrl: "header/header.html",
controller: 'HeaderCtrl'
};
}])
.controller('HeaderCtrl', ['$log', function($log) {
$log.log('test header controller');
}]);
app.js
angular.module('myApp', [
'ngRoute',
'myApp.header'
]).
config(['$routeProvider', function($routeProvider) {
$routeProvider.otherwise({redirectTo: '/'});
}]);
index.html
<script src="header/header.js"></script>
<header-bar></header-bar>

I see a typo on your directive definition:
Should be restrict: "E", you're currently missing the 't'

You need to call the app.js and angular.js reference scripts in your index page
Some think like below
//Jquery Scripts
//Angular.js library scripts
<script src="header/header.js"></script>
**<script src="app.js"></script>**// Please refer here your app.js script
<header-bar></header-bar>

This works for me.Please check that you are including all files.
<html>
<head>
<title>test</title>
<link rel="stylesheet" href="styles.css">
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js"></script>
<script src="header/header.js"></script>
<script src="app.js"></script>
</head>
<body ng-app="myApp.header" ng-controller="HeaderCtrl">
<header-bar></header-bar>
</body>
</html>

routeProvider doesn't work and controller undefined using angularjs 1.5

I'm working on my first app. When I open it in the webbrowser I get this error: Uncaught ReferenceError: controller is not defined
at app.js:3
at app.js:15
I got this error after I created the app.js file and tried to link my controller.js to it. Also the routeProvider doesn't seem to work yet. And my placeholders stopt working, which did work before.
I simplified my code to keep it readable. I've got more html files and use bootstrap in combination with JQuery and CSS. Does someone know what's going wrong here?
app.js
(function(){
var myApp = angular.module('myApp', ['ngRoute']).controller('controller', controller)
.config(function($routeProvider, $locationProvider){
$locationProvider.html5Mode(true);
$routeProvider
.when('/main', {
templateUrl: '../main.html',
controller: 'controller'
})
.otherwise({redirectTo: '../main'});
});
})();
controller.js
(function() {
angular.module('controller', ['ngRoute'])
.controller('controller', ['$scope', function ($scope) {
}]);
})();
index.html
<!DOCTYPE html>
<html data-ng-app = "myApp">
<head>
<meta charset="utf-8"/>
<title> Who Brings What </title>

There are few issues with your code,
(i)Since you have defined controller separately in a single file, you can safely remove it from the initial module.
function(){
var myApp = angular.module('myApp',['ngRoute'])
myApp.config(function($routeProvider, $locationProvider){
$locationProvider.html5Mode(true);
$routeProvider
.when('/main', {
templateUrl: './main.html',
controller: 'controller'
})
.otherwise({redirectTo: '/main'});
});
})();
(ii) You do not need to have ngRoute injected twice, You can just use the globally declared module
(function() {
app.controller('controller', ['$scope', function ($scope) {
}]);
})();

Does not show the view AngularJS

I try to show a view with angular paths. the console does not throw any error or warning.
But equally the view is not displayed.
What am I doing wrong?
index.html
<!DOCTYPE html>
<html lang="en" ng-app="app">
<head></head>
<body>
<ng-view></ng-view>
<!-- build:js bower/vendor -->
<script type="text/javascript" src="../bower_components/angular/angular.min.js"></script>
<script src="../bower_components/angular-route/angular-route.min.js"></script>
<!-- endbuild -->
<script src="./routes.js"></script>
<!-- build:app scripts/js || CUSTOMER -->
<script src="./components/customer/customerService.js"></script>
<script src="./components/customer/customerController.js"></script>
<!-- endbuild-->
</body>
</html>
routes.js
var _templateBase = './components';
angular.module('app', [
'ngRoute'
])
.config(['$routeProvider', function ($routeProvider) {
$routeProvider
.when('/', {
templateUrl: _templateBase + '/customer/customer.html' ,
controller: 'customerController',
controllerAs: '_ctrl'
})
.otherwise({
redirectTo: '/'
});
}
]);
costomerService.js
angular.module('app', [])
.factory('customerService', function() {
});
costomerController.js
angular.module('app',[])
.controller('customerController', ['$scope', function($scope, customerService) {
//
}]);
It's wrong? Because the view is not displayed? I'm using obsolete mertodos, guide me lleguar many tutorials there.
Thanks so they can help.
This creates your app because you have included the second parameter (an array of dependencies to inject):
angular.module('app', [
'ngRoute'
])
Remove the second parameter on your other angular.module() definitions because that is causing a new app to be created each time.
angular.module('app') <-- no second parameter tells it to use the existing 'app' module
.factory('customerService', function() {
});
angular.module('app') <-- no second parameter tells it to use the existing 'app' module
.controller('customerController', ['$scope', 'customerService', function($scope, customerService) {
//
}]);
I added customerService to your injection array on your controller definition because the array elements have to match up exactly to your function parameters.
Also, if you are using controllerAs syntax as you have done on your route definition then you may not want to inject $scope into your controller.

Template not loading under component design

I am trying to make a single page application while using components since my company will be moving to using components in the future and I am trying to follow the angular-phonecat tutorial. The problem I'm having is that for some reason in my app.config.js file, the template for the home page is not being recognized (the home-page portion) and I can't figure out why. If I replace that with a simple string of 'hello', it displays just fine, so it has to be somewhere in my components but I can't track down why it's not recognizing it.
Relevant code:
app.config.js:
angular.
module('newSpa').
config(['$locationProvider', '$routeProvider',
function config($locationProvider, $routeProvider){
$locationProvider.hashPrefix('!');
$routeProvider.
when('/home',{
template: '<home-page></home-page>'
}).
when('/contacts', {
template:'<contacts></contacts>'
}).
otherwise('/home');
}]);
app.module.js:
angular.module('newSpa', [
'ngRoute',
'homePage',
'contacts'
]);
home-page.template.html:
<div>
<p>{{message}}</p>
</div>
home-page.module.js:
angular.module('homePage', []);
home-page.component.js:
angular.module('homePage').component('homePage', {
templateUrl: 'home-page/home-page.template.html',
controller: 'homeCtrl'
});
controllers.js:
angular.module('homePage', []).controller('homeCtrl', ['$scope', function($scope){
$scope.message = 'hello';
}]);
index.html:
<!DOCTYPE html>
<html lang="en" ng-app="newSpa">
<head>
<meta charset="UTF-8">
<title>SPA Contacts</title>
<script src="bower_components/angular/angular.js"></script>
<script src="bower_components/angular-route/angular-route.js"></script>
<script src="app.module.js"></script>
<script src="app.config.js"></script>
<script src="home-page/home.module.js"></script>
<script src="home-page/home.component.js"></script>
<script src="contacts/contacts.module.js"></script>
<script src="contacts/contacts.component.js"></script>
<script src="controllers/controllers.js"></script>
</head>
<body>
<div ng-view></div>
</body>
</html>
My app.config.js file is in the root "app" directory, and my home files are all in the "/app/home-page" directory. Link to angular-phonecat: https://docs.angularjs.org/tutorial/step_03
So my previous solution was still incorrect. The real solution is that my controller was redefining the 'home' module because I had square brackets. Here is the old controller:
angular.module('homePage', []).controller('homeCtrl', ['$scope', function($scope){
$scope.message = 'hello';
}]);
So as you can see, when I have square brackets in the module definition, I am redefining the module, thereby overwriting all previous definitions of the module. When I removed those brackets:
angular.module('homePage').controller('homeCtrl', ['$scope', function($scope){
$scope.message = 'hello';
}]);
Everything displays properly. So the issue was I was making a new module with just the controller, so it didn't have the template to push to the view to update.
You seem to have named your component 'home' but are using 'home-page' in your template.

Getting Started With Angular Routing

I'm just getting started with Angular and seem to have fallen down at the first hurdle. I wanted to build a simple skeleton app to start with. I pretty much copied the code of the angularjs.org site and am getting an error talking about injection... Sorry to code dump, but I have no clue where the bug is.
<!DOCTYPE html>
<html ng-app="triangular">
<head>
<title>Angular Skeleton</title>
<link rel="stylesheet" href="/style/bootstrap.css" type="text/css" />
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.0-rc.2/angular.min.js" type="text/javascript"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular-route-segment/1.3.0/angular-route-segment.min.js" type="text/javascript"></script>
<script type="text/javascript">
var a = angular;
var t = a.module('triangular', ['ngRoute']);
t.config(['$routeProvider',
function($routeProvider) {
$routeProvider.
when('/page1', {
templateUrl: 'app/modules/test/partials/partial1.html',
controller: 'Page1Ctrl'
}).
when('/page2', {
templateUrl: 'app/modules/test/partials/partial2.html',
controller: 'Page2Ctrl'
}).
otherwise({
redirectTo: '/page1'
});
}]);
t.controller('Page1Ctrl', ['$scope', '$http', function($scope, $http)
{
$scope.placeholder = 'Test';
}]);
t.controller('Page2Ctrl', ['$scope', '$http', function($scope, $http)
{
$scope.placeholder = 'Test2';
}]);
</script>
</head>
<body>
<div ng-view=""></div>
</body>
</html>
I'm getting this error: Error: [$injector:modulerr].
The link it's providing isn't that useful. It told me to include the route segment js file, which I did, but the error persisted.
try adding:
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.0-rc.2/angular-route.min.js" type="text/javascript"></script>
to your head right below where you include angular. I had a similar issue and this fixed it right away.

angularjs not loading partials

I'm trying to put together a basic angularjs web page through django (but not really using django for this example). I tried to copy an example exactly, but it's not working. The partial and the controller are not loading. The url is updated, so I know the app is loading. But I don't see it hitting my web server at all for the partial or the data. Help would be appreciated.
Here is the simplest code I could put together.
test.html:
<!doctype html>
<html ng-app="ciqApp">
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.14/angular.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.14/angular-route.js"></script>
<script type="text/javascript" src="js/app.js"></script>
<script type="text/javascript" src="js/controllers.js"></script>
</head>
<body>
TEST
<div ng-view>
</div>
</body>
</html>
js/app.js
var ciqApp = angular.module('ciqApp', [
'ngRoute',
'ciqControllers'
]);
ciqApp.config(['$routeProvider',
function($routeProvider){
$routeProvider.
when('/questions', {
templateURL: '/static/partials/question-list.html',
controller: 'QuestionListCtrl'
}).
otherwise({
redirectTo: '/questions'
});
}]);
js/controllers.js
var ciqControllers = angular.module('ciqControllers', []);
ciqControllers.controller('QuestionListCtrl', ['$scope', '$http',
function ($scope, $http) {
$http.get('/get_questions').success(function(data) {
$scope.questions = data;
});
}]);
TemplateURL should be TemplateUrl. Also, you can try to remove the first slash from your templateUrl path and see if that makes a difference: So:
templateURL: '/static/partials/question-list.html',
becomes:
templateUrl: 'static/partials/question-list.html',
