Displaying factory variable directly in the view without relying on controller inheritance

Presently, I have a single factory structured as follows:

export function PageFactory() {
    var title = 'default';
    return { 
      title: function() { return title; },
      setTitle: function(newTitle) { title = newTitle }
    };
  }

Within a controller, I am injecting the factory in this manner:

constructor(private $scope:IMainScope, $rootScope, $window, $route, Page) {
    Page.setTitle('home');
}

My objective is to showcase the variable in the view using {{ Page.title }}. However, this approach does not yield the desired outcome. The only way it works is if I inject the factory and assign the title to a variable in the controller like so:

constructor(private $scope:IMainScope, $rootScope, $window, $route, Page) {
    $scope.title = Page.setTitle('home');
}

Subsequently displaying the variable as: {{ title }}. Nevertheless, my preference would be to achieve this without such additional steps.

Answer №1

To access the factory in your view, you can assign $scope.Page = Page; and then refer to it using {{ Page.title }}

Answer №2

When it comes to the coding style of classes, using controllerAs syntax is recommended. The current guidelines suggest limiting the use of $scope to essential operations such as watchers and events.

With the use of controllerAs as $ctrl,

constructor(..., private Page) {}

and

{{ $ctrl.Page.title() }}

Whether or not it is appropriate to expose the entire service to the view depends on each individual case.
