Is there an idiomatic way using ktor native sockets to send over/receive objects?

I’d recommend https://github.com/Kotlin/kotlinx.serialization, perhaps with protobuf support.

@Sam Garfinkel If I send two protobufs over TCP in quick succession, when I read the byte array what I get is the concatenation of both requests. Is there a way to avoid this? (I am flushing)… I am guessing adding a byte specifying the legnth before sending each byte array?

Yeah you’ll need to create a meta-message for serializing your stuff. Protobuf doesn’t handle message delimitation for you.
