Question

I discoverd recently chunked response. I agree that most of the time we want to work on a full response. But what if I want to work on a chunked response.

How would

Answer 1

You can define a function with the angularjs promise $q wrapping the XMLHttpRequest.

var chunkedRequestWithPromise = function () {
  var deferred = $q.defer();
  var xhr = new XMLHttpRequest()
  xhr.open("GET", 'https://yoururl.com/chunked', true)
  xhr.onprogress = function () {
    deferred.notify(xhr.responseText);
  }
  xhr.onreadystatechange = function (oEvent) {
    if (xhr.readyState === 4) {
        if (xhr.status === 200) {
            deferred.resolve('success');
        } else {
            deferred.reject(xhr.statusText);
        }
    }
  };
  xhr.send();
  return deferred.promise;
};

and use it:

chunkedRequestWithPromise().then(successFn,errorFn,notifyFn);
