Separate AngularJS Frontend from SlimPHP Backend

Hi, I have the following sample webapp angularjs/slim which works fine on Linux Server (A)
I need to separate backend slim php api and frontend angularjs app into two different webservers.
How do I adjust which files to accomplish this? It should look like this on the application server (B)

app.factory("Data", ['$http', '$location',
    function ($http, $q, $location) {

        var serviceBase = 'api/v1/';

        var obj = {};

        obj.get = function (q) {
            return $http.get(serviceBase + q).then(function (results) {
                return results.data;
            });
        };
        obj.post = function (q, object) {
            return $http.post(serviceBase + q, object).then(function (results) {
                return results.data;
            });
        };
        obj.put = function (q, object) {
            return $http.put(serviceBase + q, object).then(function (results) {
                return results.data;

        };
        obj.delete = function (q) {

}]);
