Hi @Aaron Todd, there are no public API for that. You can create wrapper writer coroutine with joinTo inside and put in finally block the logic you need

Hey @e5l thanks for the response. Can you elaborate a bit? I'm looking at joinTo now but there isn't any documentation on it.

Based on the API surface it just looks like it's copying to another channel?

Sure: https://api.ktor.io/1.3.2/io.ktor.utils.io/join-to.html here is joinTo

[e5l]

It moves the content from one channel to another

thanks, I'll see if it satisfies my needs.
