Anyone know how I can expose members to routes / application?

[cy]

Could you please explain? What exact members are you talking about?

[jkbbwr]

fun Application.main() {
    install(CallLogging)

    routing {
        get("/") {
            call.respondText("""Hello, world!<br><a href="/bye">Say bye?</a>""", ContentType.Text.Html)
        }
        get("/bye") {
            call.respondText("""Good bye!""", ContentType.Text.Html)
        }
    }
}

fun Http(host: String, port: Int) = embeddedServer(Netty, host = host, port = port, module=Application::main)
`

I have a SendChannel<Any> that I want exposed to routes. so I can then call
channel.send("test") for example

Why can't you simply capture it inside of routing lambda?

[jkbbwr]

because its defined outside of application and used elsewhere in the project

[cy]

Don't you start the relevant component inside of the module start function?
val facade = startEventConsumer(this)

[cy]

The other alternative is to make a feature that could be installed to the application via install(MyEventBus) and that could be retrieved via application.feature(MyEventBus)

[jkbbwr]

Because the consumer is shared between multiple components, ktor for http and zmq for wire transport

Found a way to achieve what I want.

fun Http(host: String, port: Int) = embeddedServer(Netty, host = host, port = port) {
    install(CallLogging)
    
    routing {
        get("/") {
            call.respondText("""Hello, world!<br><a href="/bye">Say bye?</a>""", ContentType.Text.Html)
        }
        get("/bye") {
            call.respondText("""Good bye!""", ContentType.Text.Html)
        }
    }
}
