Please have a look at the piece of code below. Now suppose i'll have hundreds of entity like "person". How would you code such a thing to get it clean, concise, efficient, well structured ? Tx
class HttpEntryPoint : CoroutineVerticle() {
private suspend fun person(r: RoutingContext) {
val res = vertx.eventBus().requestAwait<String>("/person/:id", "1").body()
r.response().end(res)
}
override suspend fun start() {
val router = Router.router(vertx)
router.get("/person/:id").coroutineHandler { ctx -> person(ctx) }
vertx.createHttpServer()
.requestHandler(router)
.listenAwait(config.getInteger("http.port", 8080))
}
fun Route.coroutineHandler(fn: suspend (RoutingContext) -> Unit) {
handler { ctx ->
launch(ctx.vertx().dispatcher()) {
try {
fn(ctx)
} catch (e: Exception) {
e.printStackTrace()
ctx.fail(e)
}
}
}
}
}

You're looking for subrouter
.
https://vertx.io/docs/vertx-web/java/#_sub_routers
From the top of my head:
override suspend fun start() {
router.mountSubrouter("/person", personRouter(vertx))
// x100 if you'd like
}
Then in your PersonRouter.kt
:
fun personRouter(vertx: Vertx): Router {
val router = Router.router(vertx)
router.get("/:id").coroutineHandler { ctx -> person(ctx) }
// More endpoints
return router
}
