It is possible to add content to a JSON file using AngularJS $http.post method?

app.controller('MainController', function($scope, $http) {
    // we create an object called formModel and used ngModel="formModel.name/email/password" 
// to create properties inside it
    $scope.formModel = {};
    $scope.jsonStructure = [];
    $scope.submitting = false;

    // function to send data when the button register is clicked
    $scope.onSubmit = function(valid) {

        if (valid) {
            $scope.jsonStructure.push($scope.formModel);

            $scope.submitting = true;
            console.log($scope.formModel);
            // function to post data to a servers using http, the first parameter is the address, the second parameter is the 
// form that we are sending, sucess is the callback to execute when the post method is completed, and error is the callback
// to execute if the post method didnt work https://minmax-server.herokuapp.com/register/
            $http.post('about.json', $scope.jsonStructure).success(function(data){
                console.log($scope.jsonStructure);
                console.log(':)');
                $scope.submitting = false;
            }).error(function(data){
                console.log(':(');
                $scope.submitting = false;
            });

        } else {

            console.log('Invalid');

        };

    };
});
