How to build nested routes in Ktor?

I defined my routes in the separate file:

PostRoutes.kt:

fun Route.getPostsRoute() {
    get("/posts") {
        call.respondText("Posts")
    }
}

// Some other routes

fun Application.postRoutes() {
    routing {
        getPostsRoute()
        // Some other routes
    }
}

And I setup these routes in Application.kt as it shown below:

fun main(args: Array<String>): Unit = io.ktor.server.netty.EngineMain.main(args)

fun Application.module(testing: Boolean = false) {
    routing { // I want to provide the root endpoint (/api/v1) here
        postRoutes()
    }
}

How can I setup my root endpoint (/api/v1) in this case?

P.S. I've checked their docs, it says to use nested routes but I can't because I need to call routing in postRoutes() that breaks nested routes.

P.P.S. I am a noobie in Ktor and Kotlin.

You can either wrap the getPostsRoute() with the route("/api/v1") inside the postRoutes method or get rid of the postRoutes method and nest your routes inside the routing {}.

import io.ktor.application.*
import io.ktor.response.*
import io.ktor.routing.*
import io.ktor.server.engine.*
import io.ktor.server.netty.*

fun main() {
    embeddedServer(Netty, port = 5555, host = "0.0.0.0") {
        postRoutes()
    }.start(wait = false)
}

fun Route.getPostsRoute() {
    get("/posts") {
        call.respondText("Posts")
    }
}

fun Application.postRoutes() {
    routing {
        route("/api/v1") {
            getPostsRoute()
        }
    }
}
