Hello everyone, I curious about chat system, I want to build chat system on Ktor framework.
so Do you think Socket.IO can have powerful to build medium/large chat system.?
Or Can you suggestion some technical to build medium/large chat system ?
Thanks

[gildor]

How socket.io related on Ktor. Isn't it JS-only library for server and client?

[Sam]

I see some guys are using socket IO and kotlin
https://github.com/kolyagithub/kotlin-socketio

[Sam]

or I get wrong somethings?

[gildor]

This is socket.io JVM client

[gildor]

But Ktor is server

[Sam]

OK I got it. Thankssss @gildor
So Which technologies can build chat system base on Ktor?

[gildor]

Ktor can work as Websockets server, nothing more

[gildor]

You of course can implement some chat application with pure websockets and some protocall

[gildor]

But I want to add, that this is too broad task, there are many variables so it’s impossible to answer with no context “what would be better”

We are using socket.io (netty) for a medium-large scale realtime chat backend. Backend-side works fine. I just won’t recommend the android and ios socket.io libraries. In case you don’t need fallback for long-polling, i would suggest you to use just websockets instead of socket.io. In fact we are also planning to migrate from socket.io to ktor.

Thanks for your information. really helpful
we are also planning to migrate from <http://socket.io|socket.io> to ktor. => You mean you are using Socket.IO(with only Netty server framework) for medium-large scale realtime chat backend , right ? and How about communicate between Mobile and Backend without socket.io ?

We are using https://github.com/mrniko/netty-socketio.
With plain websockets.

Thanks @vonox7

If Ktor had first class support for the socket.io protocol that would be pretty awesome, though
