Hello, please advise where to start (what web framework) if I want to use asynchronous web server with asynchronous postgres driver (found port from scala). Coming from Scala, new in Kotlin, now in process of selecting the platform. Thanks in advance!

Maybe the Play framework? It has Java APIs after all

Too big and complex for my needs.. Also, it tastes better in Scala.

I used Spark, others use Spring (Boot) and Vertx. Those are Java frameworks, but everything works out-of-the-box with Kotlin

Thanks for vertx link! I'm looking into it now. About web section, it's not clear whether particular framework supports async execution.

ratpack should work fine with kotlin
