Ionic auto caching


#1

I have a use case where there the users will be greeted by -LoginPage (LoginController)

On login, login details & user information are added to the factory called UserData. The app will be directed to a tabbed controller. Information from UserData will be used to provide personalization, fill out $scope.displayName etc,.

.controller('DashCtrl', function($scope, userData) {
    $scope.name = userData.data.name; 
})

As caching is enabled, the respective tab dashboard controller is not getting fired.

It took a while to figure out that caching is enabled by default and had to be turned off

  .state('tab.dash', {
    url: '/dash',
    cache: false,
    views: {
      'tab-dash': {
        templateUrl: 'templates/tab-dash.html',
        controller: 'DashCtrl'
      }
    }
  })
  1. Is it a good approach from IonicFramework to turn on caching by default? It might inconvenience the new users as they need to figure out why controller is not firing. I understand the trade-off : better performance

  2. What are the the recommended coding approaches to make use of caching and pass data from login controller to tab based controllers through factories or other means.

  3. Will the following code snippet benefit from caching as it will enter the watch cycle again

    $scope.$on(’$ionicView.afterEnter’, function(){
    // Any thing you can think of
    });
