Support AbortSignal.timeout()

[johanneswuerbach]

Suggestion

Add support for whatwg/dom#1032 to the AbortSignal types.

🔍 Search Terms

AbortSignal, abort signal, timeout

✅ Viability Checklist

My suggestion meets these guidelines:

• This wouldn't be a breaking change in existing TypeScript/JavaScript code
• This wouldn't change the runtime behavior of existing JavaScript code
• This could be implemented without emitting different JS based on the types of the expressions
• This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, new syntax sugar for JS, etc.)
• This feature would agree with the rest of TypeScript's Design Goals.

⭐ Suggestion

📃 Motivating Example

The implementation in NodeJS nodejs/node#40899

💻 Use Cases

I think it is the same issue as #48444, looks like AbortSignal.timeout hasn't made it to the major browsers yet.

Here are the implementation tickets from the browsers:

• https://bugs.chromium.org/p/chromium/issues/detail?id=1181925
• https://bugzilla.mozilla.org/show_bug.cgi?id=1753309
• https://bugs.webkit.org/show_bug.cgi?id=236039 (seems to be resolved)

This feature has now shipped in (at least) Chrome, Firefox & Safari: https://chromestatus.com/feature/5768400507764736.

This is now supported by all major browsers across the board. It's time to add the type.

[saschanaz]

The type has been there for a while in https://github.com/microsoft/TypeScript-DOM-lib-generator/, the remaining work is to fetch that lib here.

If you are in hurry, you can try https://www.npmjs.com/package/@types/web instead of waiting for a new TS release.

[ianschmitz]

This is in the latest TypeScript. It appears to have been introduced in 4.9.5. See example: https://www.typescriptlang.org/play?ts=4.9.5#code/IIIw9gTgLgyglgcwHYEMA2A6KcC2BTMAVygAoBWABioEog

I think this ticket can be closed as completed.
