Design review: AbortSignal.any()

[shaseley]

Braw mornin' TAG!

I'm requesting a TAG review of AbortSignal.any(signals).

AbortSignal.any(signals) returns a signal that is aborted when any of the source signals are aborted. Developers can use this to combine independent abort sources, e.g. timeouts specified with AbortSignal.timeout() and signals associated with user input, and pass them to async APIs like fetch().

• Explainer: https://github.com/shaseley/abort-signal-any/blob/main/README.md
• User research: N/A
• Security and Privacy self-review: https://github.com/shaseley/abort-signal-any/blob/main/tag-questionnaire.md
• GitHub repo (if you prefer feedback filed there): https://github.com/shaseley/abort-signal-any/
• Primary contacts (and their relationship to the specification):
  • Scott Haseley (@shaseley), Google, designing/specifying/implementing in Chrome
• Organization/project driving the design: This is in response to an open WHATWG DOM issue
• External status/issue trackers for this feature (publicly visible, e.g. Chrome Status): https://chromestatus.com/feature/5202879349522432

Further details:

• I have reviewed the TAG's Web Platform Design Principles
• The group where the incubation/design work on this is being done (or is intended to be done in the future): The explainer will likely stay in a personal repo, with conversation moving to a WHATWG (DOM) PR.
• The group where standardization of this work is intended to be done ("unknown" if not known): WHATWG
• Existing major pieces of multi-stakeholder review or discussion of this design: Consider adding AbortController.prototype.follow(signal) whatwg/dom#920 (comment)
• Major unresolved issues with or opposition to this design: None we're aware of
• This work is being funded by: Google

We'd prefer the TAG provide feedback as (please delete all but the desired option):

🐛 open issues in our GitHub repo for each point of feedback

Hi there,

We looked at this during a breakout today and we think this is ok — the addition does not introduce any new issues to the AbortSignal API.

Thank you for working with us!

Thanks all!

FYI: this feature has been merged into the dom spec (with no changes to the API since TAG review).
