Question from the Ionic Framework test

Using resolve in the configuration of an ui-router state:

$stateProvider
  .state('todos', {
    url: '/todos',
    controller: 'TodosCtrl',
    templateUrl: 'todos.html',
    resolve: {
      todos: function(TodosService) {
        return TodosService.getTodos()
      }
    }
  })

Using the localStorage

Using AngularJS services which are singletons

Using AngularJS events:

scope.$broadcast('event', ...);
