But if you do go ahead and make such a tool, let me know and I’ll use it next time I need to work with SOAP or something. 😉

Spring is far too large and used everywhere (at least in the US) and is up to version 5 and has a lotttt more features. Micronaut's first release was last year. No.

But its WIP

You can just use the same java frameworks you already do, or you can jump to something more focused on kotlin, e.g. ktor, which makes heavy use of coroutines

Any suggestions?

Hey guys, Is there any tool/plugin to auto-generate api documentation that integrates with ktor?

and here is the HelloWorld-project that I created to make the testing of your ideas easy (it simply starts Ktor on port 8090 which replies with "Hello World"): https://github.com/stephan-at-which/gradle-with-kotlindsl-fatjar/tree/problem What am I doing wrong?

When using Kotlin with Spring MVC you can use SpringFox to produce Swagger based on the MVC annotations and controllers and you can add more documentation with SpringFox specific annotations.

What are some key techniques used to troubleshoot SSL connections on the server end? Have a situation where Jetty will often timeout SSL connections (aka close the channel), even with light loads (via HTTPS). Timeouts only occur when using the Android client. Postman works fine without any issues.

Hi folks 👋

sealed class MySealed {
    data class A(val value: String) : MySealed()
    data class B(val value: String) : MySealed()
}

fun reactor() {
    val result: Mono<MySealed> = Mono.just("bla")
        .map { MySealed.A(value = "A") }
        .onErrorResume { Mono.just(MySealed.B("B")) }

    // Compilation ERROR
    // map -> Type mismatch: inferred type is Mono<MySealed.A!> but Mono<MySealed> was expected
    // onErrorResume -> Type inference failed. Expected type mismatch: inferred type is Mono<MySealed.B!> but Mono<out MySealed.A!>! was expected
}

If a just use any other class type (data class, enum, etc), it works.

Yeah, annoyingly casting it to

as MySealed

should fix it

yeah...

.map<MySealed>

solved it 😉

Thank you for answering my questions. Seems like a friendly community which is always a big bonus! 🙂 I’ll try and re-write one of the scala services and see how I like it!

Hi, does anyone use Kmongo library? Documentation says that queries typesafe when used KPropery extensions. But it possible to write collection.find(Some::stringProperty eq 5). Maybe I am doing something wrong?

Hello! I am using Ktor framework to build a web app and I am playing around with the built-in jackson content negotiation, I have data classes that I must respond back to the client side using call.respond(status = HttpStatusCode.OK) {return@respond patientList} where patientList is a list<JSONPatient> and JSONPatient is a data class that has nested data classes but it is all primitive types.I keep getting this error message and i can't figure out why.

ERROR Application - 307:reportUnresolvedClass - This class is an internal synthetic class generated by the Kotlin compiler, such as an anonymous class for a lambda, a SAM wrapper, a callable reference, etc. It's not a Kotlin class or interface, so the reflection library has no idea what declarations does it have. Please use Java reflection to inspect this class: class com.wallscope.casebook.api.routes.patients.PatientsKt$patients$1$1$2

Did you add the kotlin module to your objectmapper? See #ktor and #jackson-kotlin also

I installed jackson through the ktor install mechanism , I managed to get it working by doing call.respond(HttpStatusCode.OK, patientList) without an anonymous block

with the following pom.xml file for a module

To fix it I have to add the following block

to the kotlin-maven-plugin plugin. Could you tell me why it is required?

from IntelliJ IDEA, how would I start a new web app project with Kotlin, which template would I go for?

TechEmpower benchmark Round 18 was published: https://www.techempower.com/benchmarks you can check Kotlin performance on the server there 😉

hey you guys, fairly new to Kotlin. I have some validation logic that is working as expected, but when testing it through Postman, it returns the correct validation but a 500 http response instead of a 404 (since this should be a bad request). any tips on how to change the http response in code?

what are you using for your server framework

many of them have their own exception->status page translation modules
