Verticles and Handling Requests

Splitting code into verticles in Vert.x

Our current code resides in the App.kt file, which is getting bigger and bigger. We need to find a way to split it. In Vert.x, code is split into classes called verticles.

We can think of a verticle as a lightweight actor.

Let’s see how we can create a new verticle that will encapsulate our server:

class ServerVerticle : CoroutineVerticle() {
    override suspend fun start() {
        val router = router()
        vertx.createHttpServer()
            .requestHandler(router)
            .listen(8081)
        println("open http://localhost:8081")
    }

    private fun router(): Router {
