Hello everyone, I am trying to implement websocket feature with ktor, but I only get 404 for the http://localhost:8080/ request in browser. Could you, please, tell me what can be wrong?

Here is my websocket implementation:

webSocket("/") {
    while (true) {
        delay(3000)
        outgoing.send(Frame.Text("hi"))
    }
}

Hitting that from the browser isn't making a websocket request, it's an http request. They are fundamentally different. You'd have to use a web socket client to make the request there, AFAIK

I also tried to use chrome extentions to make that call with ws:// scheme. But it still not found

What's your main config look like? Do you have the right port?

[Kirill Prybylsky]

ktor {
    application {
        modules = [com.pinkydev.server.MainAppKt.main]
    }
}

This is the config file

But what port is that listening on? If you make an http get handler at / does that work on port 8080?

[Kirill Prybylsky]

From the console output it runs on localhost:8080/

Also, I notice you aren't using the incoming receive channel at all in your handler. Perhaps that's the problem? I think this code might just get stuck in q loop since it's not using for (frame in incoming)

I thought it isn’t required to use. I only need output one.🤔

I installed intellij idea and ktor plugin (previously was android studio)
and there was some websocket config so it seems to work with this setup, but only with generated client (not in browser)
