The Fetch API might seem new to some, but it’s already five years old with browsers rolling out support in 2015. It was a replacement for the dated XMLHttpRequest which was tedious to work with and a relic of the yesteryear of internet.

Still, all of these years one feature that is available in XMLHttpRequest is the ability to handle file upload progress, missing from the Fetch specification and we are now in the year 2020, almost 2021 and still, there is no across the board way to handle file upload progress. This is the last missing piece before Fetch can truly replace XMLHttpRequest.
