Angular.js ng app is known for much more than just its controllers

I'm a beginner in Angular.js and facing an issue with setting up the controllers. When I try to run my code in the browser, I encounter an error

'uncaught referenceError: myappApp is not defined'
for
myappApp.controller('HomeController'...)
. It's puzzling because ng-app='myappApp' is properly set and functioning, as well as being defined in angular.module('myappApp'...). Everything else seems to load fine.

one@localhost ~/angular.js-project/myapp/app $ cat scripts/app.js 
'use strict';

angular
  .module('myappApp', [
    'ngCookies', 'ngRoute'
  ]).config(function($routeProvider) {
      $routeProvider.when('/home', {
      templateUrl: 'views/home.html',
      controller: 'HomeController'
      });

      $routeProvider.when('/first', {
      templateUrl: 'views/first.html',
      controller: 'FirstController'
      });



      $routeProvider.otherwise({ redirectTo: '/home'});
  });


myappApp.controller('HomeController', function($scope, $location, $anchorScroll) {
    $scope.scrollTo = function(id) {
    $location.hash(id);
    $anchorScroll();
    }
});

myappApp.controller('FirstController', function($scope, $location, $anchorScroll) {
    $scope.scrollTo = function(id) {
    $location.hash(id);
    $anchorScroll();
    }
});

Answer №1

To accomplish this task, you have two options:

var myappApp = angular
  .module('myappApp', [
    'ngCookies', 'ngRoute'
  ])

Alternatively, you can also use:

angular.module('myappApp').controller(...)

If you use myappApp.controller, the code will look for a variable named myappApp which has not been defined anywhere in the script. Therefore, either assign the result of angular.module to it or continue using angular.module as shown above.
