AngujarJS server-side pagination grand total items using $resource

Question

I'm trying to implement server-side pagination on an AngujarJS app but haven't figured out how to get the grand total (not the per-request total) items in a given JSON response without having to do an additional request:

$scope.books = [];
$scope.limit = 3;
$scope.offset = 0;

$scope.search = function () {
    Books.query({ q: $scope.query, limit: $scope.limit, offset: $scope.offset },
        function (response) {
            $scope.books = response;
        }
    );
};

$scope.previous = function () {
    if ($scope.offset >= $scope.limit) {
        $scope.offset = $scope.offset - $scope.limit;
        $scope.search();
    }
}

$scope.next = function () {
    if ($scope.offset <= $scope.limit) {
        $scope.offset = $scope.offset + $scope.limit;
        $scope.search();
    }
}

I've been looking at great contributed directives such as ng-table and ng-grid which already implement this as well as other useful features but I just want to be able to implement this one functionality from scratch to really learn the basics.

Sounds like you are struggling with your api more than angular.
