Does kotlin have framework/built in lib for creating tcp server

[asad.awadia]

<https://www.bogotobogo.com/Java/tutorials/tcp_socket_server_client.php> you can use this but in Kotlin

[Zdziszkee]

Thanks, now i have to figure out how to send objects though it

[asad.awadia]

Serialise the object into bytes
Or convert it to json and send it

[Matteo Mirk]

TCP is just a transport layer, so you can put anything into its packets: it’s just byte chunks to the protocol. The meaning you give to those bytes depends on your application layer. Performance-wise, I’d recommend going with binary serialization, like Asad suggested.

As for TCP sockets I would recommend using those exposed by Ktor and not the JDK ones: https://ktor.io/docs/servers-raw-sockets.html#sockets

[Zdziszkee]

Ktor do not support async sockets so u can not create non blocking network if im right

[Matteo Mirk]

I don’t know these details, you should try to ask in #ktor directly to project maintainers

@Zdziszkee I used Kotlin's / Java's built-in sockets for a project:
