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);
