hey peeps, I'm working on a noddy project for my own learning and I need to create a websocket connection (as a client) to a home assistant instance. I need bi-directional, asynchronous communication and I've got it working, but I think I'm being an idiot 🧵

class CommonHaService {
    val json = Json {}
    private val client = HttpClient {
        install(WebSockets)
    }

    var commandId = 1

    private val commandChannel = Channel<HAServiceCall>()
    private val commandFlow: Flow<HAServiceCall> = flow {
        while (true) {
            // Forward received commands to command flow collector
            emit(commandChannel.receive())
        }
    }

    val eventFlow = flow<HaServiceEvent> {
        var authed = false

        client.webSocket("...") {
            async {
                commandFlow.collect {
                    // Handle sending data
                }
            }

            incoming.receiveAsFlow().catch {
                emit(HaServiceEvent.Disconnected)
            }.collect {
                // Handle receiving data
            }
        }
    }
}

cheers Adel, I'll have a look, thanks for the links!

[czuckie]

I've had a quick look, are you using websockets?

[czuckie]

I can't seem to find any references 😞

[Adel Ayman]

Yeah
