Session Proposal: Support Cancellation (AbortController) in Node.js core

[benjamingr]

Proposal

Topic of the session Landing AbortController and probably also EventTarget in Node Core.

Related to the fetch in core topic from last year (cc @MylesBorins @mcollina)

Related to other parties interested in cancellation or that I recall having said interesting things to me about it (cc @benlesh @littledan @jakearchibald @devsnek @ljharb @BridgeAR @nodejs/open-standards @felixfbecker )

Type of the session

• Collaborate
• Workshop
• Talk

Timezone of facilitator GMT+2 but I will make myself flexible to other participants.

Estimated duration of the session 2 hours

Follow-up / Set-up sessions (if any) probably background in nodejs/node#19393 https://docs.google.com/document/d/1tn_-0S_FG_sla81wFohi8Sc8YI5PJiTopEzSA7UaLKM/edit and others.

Participants will be able to contribute and we want opinions even if you were not involved at all until this point.

Level

• Beginner
• Intermediate
• Advanced

Pre-requisite knowledge

To best collaborate people should be familiar with AbortController EventTarget and EventEmitter.

Describe the session

Do we want to include AbortController in core? Does that mean we also have to include EventTarget?

How should core handle cancellation? What should the user stories be?

Session facilitator(s), Github handle(s) and timezone(s)

Benjamin Gruenbaum - @benjamingr - GMT + 2

I am fine with anyone else facilitating this although I am also fine with facilitating this myself.
I would be happy to attend the promises session as well.

Additional context (optional)

This section is for contributors handling Collaborator Summit logistics

Track

• New Contributor Orientation Track (see New Contributor Orientation Track #251)
• Regular Track
• Cross-Project Track

Triage

• Track chosen
• Scheduled

Note: @littledan pointed out that it would be very useful to have some DOM people in the meeting to provide feedback from that perspective and I agree. If anyone can invite some relvant parties that would be helpful.

I forgot to ping a bunch of people who are really smart and have a lot to contribute on the topic - as usual - I hope I am forgiven and they still show up for the session :]

[MylesBorins]

I'm not sure this project makes sense for season of docs... The focus is supposed to be technical writing.

[devsnek]

@MylesBorins the focus of the entire collab summit is technical writing?

[benjamingr]

I'm a bit confused, the collab summit is the one space we get together and discuss these issues. If there is another more appropriate space or if in particular this year this session isn't a good fit that's fine.

Of course: this is a session proposal, I promise to still collaborate in good faith in the project if this session proposal gets rejected though this is like... the one time a year we take part of these
sort of discussions as a project.

[ljharb]

I think it would be a very bad idea for language-level cancellation (there remains a proposal) if there was further proliferation of cancellation mechanisms in platforms, beyond fetch in browsers.

[MylesBorins]

Apologies, I looked at this right after waking up and read the repo wrong. Please ignore my comment

[benjamingr]

@ljharb that's a good point - Maybe @rbuckton could attend this and help provide feedback from the TC39 proposal PoV?

[devsnek]

I'll also be there and I'm happy to wear my delegate hat if we can't get one of the champions of that proposal.
