```fun main() = runBlocking { val httpClient = HttpClient { install(Logging) { ...

# coroutines

[Sourabh Rawat]

fun main() = runBlocking {

    val httpClient = HttpClient {
        install(Logging) {
            level = LogLevel.ALL
        }

        @OptIn(KtorExperimentalAPI::class)
        install(WebSockets)

        expectSuccess = false

        install(JsonFeature) {
            @OptIn(KtorExperimentalAPI::class)
            acceptContentTypes = listOf(ContentType("application", "json-rpc"))
            serializer = KotlinxSerializer()
        }
    }
    val wss =httpClient.webSocketSession(method = HttpMethod.Get, host = "127.0.0.1", port = 6800, path = "/jsonrpc")
    wss.close()
}

this does not stop the program. what am I doing wrong?

shouldn't it just stop the program after wss.close() ?

[Saul Wiggin]

wws.close() closes the websocket. If you want to cancel the coroutine to stop the program then you could use main.cancel()

[Sourabh Rawat]

I mean, I am not asking wss.close to close the coruotune. What I want is that the main finishes which doesn't if I use this wss snippet. If I replace all wss code with just println, then main finishes

[Joris PZ]

Are you sure it's actually connecting at all? The API documentation is practically non-existent, but I think the call to websocketSession suspends until the connection is established, and so main wouldn't finish until it does

[Big Chungus]

you need to close httpClient as well 🙂

[Big Chungus]

Also, instead of doing fun main() = runBlocking{} you can do suspend fun main() {}

[Sourabh Rawat]

thats the fix i needed. thanks. Also, was suspend mani recent feature?

[Big Chungus]

I've discovered it a month or so ago. No idea when it was actually introduced.

wait what? main suspend functions are a thing?
