angular-q-spread

Add spread method to all promises created by the $q service.

spread can be used as a replacement for then. Similarly, it takes two parameters, a callback when all promises are resolved and a callback for failure. The resolve callback is going to be called with the result of the list of promises passed to $q.all as separate parameters instead of one parameters which is an array.

spread can be chained onto every promise.

#Compatibility This plugin has been tested with Angular 1.2 and 1.3

#Usage Add $q-spread as dependency when creating your angular module.

#Example angular.module('test', ['$q-spread']);

function TestCtrl($scope, $q, MyService) {
    $scope.name = null;

    function firstCallback(firstname, lastname)
    {
        return firstname + ' ' + lastname;
    }

    function anotherCallback(fullname)
    {
        $scope.name = fullname;
    }

    function failureCallback(reason)
    {
        alert('Could not load data: ' + reason);
    }
    
    $q
        .all([
            MyService.getFirstname(),
            MyService.getLastname()
        ])
        .spread(firstCallback)
        .then(anotherCallback)
        .catch(failureCallback);
};

TestCtrl.$inject = ['$scope', '$q', 'MyService'];

angular.module('test').controller('TestCtrl', TestCtrl);
