Angular's alternative to jQuery deferred.always() callback

Question

Angular's alternative to jQuery deferred.always() callback

Utilizing the .always() callback function in jQuery allows us to manage responses, regardless of whether they are successful or not.

Is there a similar functionality in AngularJS that serves the same purpose?

//jQuery
$.get( "test.php" ).always(function() {
  alert( "$.get completed with success or error callback arguments" );
});

//AngularJS
$http({
  method: 'GET',
  url: '/someUrl'
}).then(function successCallback(response) {
    //success
  }, function errorCallback(response) {
    //error
  });

//How can the 'always' scenario be handled in AngularJS?

Answer 3

Answer №2

Utilizing the finally() method in the context of the $q service serves the following purpose:

$http({
  method: 'GET',
  url: '/someUrl'
}).then(function successCallback(response) {
    //perform actions on success
}).catch(function errorCallback(response) {
    //handle errors
}).finally(function() {
    //Callback method
    //Executed regardless of success or failure
});

A crucial point to note when dealing with promises returned from the finally() callback:

The finally method returns a promise that will be resolved with the same result or error as the initial promise. However, if the callback function returns a promise, the resolution of the overall promise will be delayed until the returned promise from the callback function is completed.
