Timeout/End-user abort

[ahutchings]

How would I implement a timeout similar to jQuery's $.ajax timeout option? The fetch standard mentions an "end-user abort", but I don't see any detail on how it would be triggered.

This is probably a question for the whatwg/fetch repository or the whatwg mailing list. I'm curious about the answer as well. It seems like timeout and abort are outside the scope of the current Fetch API standard.

For what it's worth, XHR has a timeout attribute, so it might be a good idea to propose your idea to whatwg.

Hey fetch community, is there any practice or even proposal to handle timeout/end-user abort using the fetch API?

Not being able to do this there may be memory leaks and inconsistencies.

Anyway thumbs up for fetch, really cool stuff.

FWIW, I've opened an issue whatwg/fetch#951 with a proposal for a timeout option that solves 90% of use cases, in case anyone's interested. I think it's super important to add to make sure calls to fetch (or res.json()) don't hang indefinitely.
