XMLHttpRequest testing in Jest
The jest api has changed a bit. This is what I use. It doesn’t do anything but it’s enough to render my components. const xhrMockClass = () => ({ open : jest.fn(), send : jest.fn(), setRequestHeader: jest.fn() }) window.XMLHttpRequest = jest.fn().mockImplementation(xhrMockClass) and in the test file: import ‘../../__mock__/xhr-mock.js’
How to set iframe content of a react component
TLDR; If you’re looking for a way to control the contents of an <iframe> via React in a de-facto canonical way, Portals are the way to go. And as with all things Portal: Once you establish a reference to an existing and mounted DOM node (in this case that would be the contentWindow of a … Read more
NETWORK_ERROR: XMLHttpRequest Exception 101
If the url you provide is located externally to your server, and the server has not allowed you to send requests, you have permission problems.

Cross-domain XMLHttpRequest using background pages
You don’t have to mess with iframes. It’s possible to perform cross-domain XMLHttpRequests, using background pages. Since Chrome 13, cross-site requests can be made from the content script. However, requests can still fail if the page is served with a Content Security Policy header with a restricting connect-src. Another reason for choosing the nexy method … Read more
How to send 1000 XHTTP Requests with maximum number of parallel requests
You could try to use RxJS bufferCount and concatMap operators along with forkJoin(). From bufferCount docs: Collect emitted values until provided number is fulfilled, emit as array. So it collects n number of notifications and emit it as an array. We could then pass the array through forkJoin() for n number of parallel requests. Try … Read more

XHR request URL says does not exist when attempting to parse it’s content

XmlHttpRequest.responseText while loading (readyState==3) in Chrome
Chrome has a bug where it will only populate xhr.responseText after a certain number of bytes has been received. There are 2 ways to get around this, Set the content type of the return to “application/octet-stream” or Send a prelude of about 2kb to prep the handler. Either of these methods should make chrome populate … Read more
Adding X-CSRF-Token header globally to all instances of XMLHttpRequest();
I’d recommend to intercept calls to the send method: (function() { var send = XMLHttpRequest.prototype.send, token = $(‘meta[name=csrf-token]’).attr(‘content’); XMLHttpRequest.prototype.send = function(data) { this.setRequestHeader(‘X-CSRF-Token’, token); return send.apply(this, arguments); }; }()); This won’t add the header at instantiation time, but right before the request is sent. You can intercept calls to new XMLHttpRequest() as well, but that … Read more
