Is there a way to prevent the page from loading before the data is ready, avoiding the view updating while the page is still loading?
I have been successful in using a 'resolve' in UI-router to run a method and fetch data before loading the page, but I am restricted to only using one method. Is it possible to run multiple methods in a resolve prior to loading the page?
It is worth noting that resolve can also accept an object. Each property within the object must be resolved before the controller is instantiated, thereby allowing the desired state to be achieved.
In the example below, all objects listed in the resolve section must be resolved (using
deferred.resolve()if they are promises) prior to the instantiation of thecontroller. It is important to observe how each resolve object is injected as a parameter into the controller (UI-Router documentation on resolve).
Here is an example to demonstrate:
$stateProvider.state('myState', {
resolve: {
resolve0: function () { // resolve with a plain value
return 'somedata';
},
resolve1: function ($q) { // resolve with a promise
return $q.resolve('somedata');
},
resolve2: function ($q) { // reject with a promise, preventing the state from completing the change
return $q.reject('some error');
}
}
}
