I understand XMLHttpRequest doesn't work with service worker (Chrome Extension manifest v3) so I need replacement of it for the following upload functionality. I am not sure how standard fetch how can be used for uploading with events like onreadystatechange and onprogress. Any example of fetch for upload purpose with events would be appreciated

var request = self.uploadXHR[index] = new XMLHttpRequest();
request.onreadystatechange = function () {
    
};

request.upload.onprogress = function (e) {
    
};

request.open('PUT', url, true);

request.send(blob);

Use the standard [fetch](https://developer.mozilla.org/en-US/docs/Web/API/fetch). – wOxxOm Mar 05 '22 at 21:43
@wOxxOm does fetch offer onreadystatechange and onprogress events? – Farukh Zahoor Mar 05 '22 at 21:45
No, it doesn't but there is a workaround for uploading, which you can find yourself. – wOxxOm Mar 05 '22 at 21:45
@wOxxOm Any example of it would be appreciated – Farukh Zahoor Mar 05 '22 at 21:46
Yeah, there should be lots of examples around, it's a popular demand, keep searching. – wOxxOm Mar 05 '22 at 21:52

@wOxxOm http://devdoc.net/web/developer.mozilla.org/en-US/docs/Web/API/FetchObserver.html Check the browser compatibility for it. Are you sure it works? – Farukh Zahoor Mar 05 '22 at 22:11
The observer isn't yet implemented. The topic I've linked contains examples of workarounds. You can find more yourself, if you don't like these – wOxxOm Mar 05 '22 at 22:14
