In node you can listen for the response "close" event, and check if .end() has been called.

Is there an equivilent for the bun http server?

You can use AbortSignal

Nice! Does it get passed into the fetch function?

Request: signal property - Web APIs | MDN

The read-only signal property of the Request interface returns the AbortSignal associated with the request.

Web standards, gotta love em.

#

While I'm here, is there a way to detect once the Response has been fully sent?

not sure
perhaps if youre using a ReadableStream, it will call the close handler on it
not 100% sure if this is called on socket end or simply "i read all the data"

Hmm. Basically I want to include bun sending the response in telemetry spans.

This is working, thanks 🙂 (making an offical http integration for the effect-ts ecosystem, and needed to integrate with effect's interruption model)
