benjamingr / cancellation-use-cases Goto Github PK

Add a use case for an SDK maintainer for a cloud provider that needs to use tokens throughout their worker/functions implementation.

Copied from whatwg/dom#920

• Create explainer skeleton. https://github.com/benjamingr/cancellation-use-cases/tree/main/cancellation
• Add example use cases, including simple code samples so that people get the idea, plus a sketch of more complicated real-world situations.
• Add description of the problem clearly as illustrated in the use cases.
• Add comparison with other ecosystems and languages.
• Add discussion of how people solve this today, and what the drawbacks are.
• Add comparison between different APIs and their pros/cons and how they would look with the above use cases. Namely: new AbortController(...signals), new AbortSignal(...signals), AbortSignal.race(signal, otherSignal), signal.follow(otherSignal).
• Add discussion of alternative approaches that would enable implementing this in userland (weak event handlers and dispose on the signal that removes the listener).
• Set up meeting to discuss the above and invite interested parties to solicit feedback.

Also big thanks to @domenic for this list, roughly taken from here.
