    Hey There.

    New to Web API and am stuck for about a week now.

    I am following this article

    The author is using Angular for his client controller and is fetching records from a database, and I have implemented something similar:

    //define angularJS module
    var app = angular.module('FFPA', []);
    app.controller('myCtrl', function ($scope, $http, EmployeesService) {
        var data;
        $scope.employeesData = null;
        //Fetches records from the factory at bottom of script file
        EmployeesService.GetAllRecords().then(function (d) {
            $scope.employeesData = d.data;      //success.
            data = d.data;
        }, function () {
            alert('Error Occurred!')            //failed.

    And then there's a factory implemented outside the Angular controller:

    app.factory('EmployeesService', function ($http) {
        var fac = {};
        fac.GetAllRecords = function () {
            return $http.get('api/Employee/GetAllEmployeesByFloor?Floor=3');
        return fac;

    The problem is that I need to wait until data is returned to do any work, so how can I implement a promise to wait until data is returned from my service?

    For example:

    //need to wait until service returns data to do this or I get an error when data.filter executes..
    groups.each(function(i,d){ var thisData = data.filter(function (d) { Do some stuff.. } }); });
