ktor-http-api-sample's Issues

weird configutation files in resources folder

It took me a while to figure out how fun Application.module() was being called. Turrns out it is written in application.conf.

What is the reason it was added? problem is that it has barely working automcomplete, ctrl+q doesnot work, no syntax check... What does it exactly solve, lets say it was a kotlin file with DSL code, what drawback would it have?

SerializationException

I get this exception when trying to manually test with Postman.

IDEA reports an error

When I am copying CustomerRoutes.kt:

       delete("{id}") {
            val id = call.parameters["id"] ?: return@delete call.respond(HttpStatusCode.BadRequest)
            if (customerStorage.removeIf  ({ it.id == id }) {
                             //‘removeIf' unresolved;‘it.id' unresolved
                call.respondText("Customer removed correctly", status = HttpStatusCode.Accepted)
            } else {
                call.respondText("Not Found", status = HttpStatusCode.NotFound)
            }
        }

into my project my IDE reports an error said:
Unresolved reference: removeIf
Unresolved reference: id

Could you tell me how to fix?

Sample should use Kotlin gradle (kts) over Groovy for consistency

I would expect that most Kotlin developers are more familiar with the Kotlin variant of gradle build files. To reduce unnecessary complexity, the sample build file should be provided in Kotlin rather than Groovy.
