I am surprised that Fetch doesn’t yet have a way to track upload progress — you have to go back (20+ years) to XMLHttpRequest! There’s a nice observer proposal linked here though. jakearchibald.com/2025/fetch-s...

jakearchibald.comFetch streams are great, but not for measuring upload/download progressThey're inaccurate, and there are better ways.
