HttpClient extends CoroutineScope. Is it safe and recommended to use this scope to launch coroutines, e.g. to implement logic tied to the client's lifecycle?

I would assume so, based on the ktor server application documentation:

https://github.com/ktorio/ktor/blob/a2e934dc42553da4a43d4bb1c1806cfaeed5fa93/ktor-server/ktor-server-core/jvmAndNix/src/io/ktor/server/application/Application.kt#L82-L83

It is also the application coroutine scope that is cancelled immediately at application stop so useful for launching background coroutines.

My assumption is that the design of the HttpClient being a CoroutineScope behaves similarly: as long as its scope isn't cancelled, it could actually be the best place to launch your coroutines?

Yes.

Thanks!

I had this approach working, but I wondered if it was good practice
