Hybrid Application Developer Interview Question:

Explain me how do you pass data from one view to another in Ionic applications?

Submitted by: Muhammad

Ionic uses AngularJS and UI-router. It means you can use Angular services or UI-router's state resolve to pass data from one view to another. Since Angular services are singletons, data stored in services can be accessed across other Angular controllers.

As mentioned, UI-router provides a resolve configuration. For example:

$stateProvider
.state('todos', {
url: '/todos',
controller: 'TodosCtrl',
templateUrl: 'todos.html',
resolve: {
todos: function(TodosService) {
return TodosService.getTodos()
}
}
})
One advantage of resolve over stateful services is better testing: as resolve injects dependencies in the controller, it is easy to test them.
