Very interesting. I'm curious as to why it is easier in Kotlin. Are there fewer choices? Does the community rally around one stack?

Not sure, but with Spring Boot it's as simple as adding a dependency at annotating one class. Writing a RESTful controller is again just annotating one class (with one annotation).

Create a Resource Controller

That's actually quite long winded, with Kotlin, it's a lot smaller codebase.

Here's an example I put together in 5 minutes

https://github.com/dharrigan/simple-rest-kotlin/blob/master/src/main/kotlin/com/example/demo/DemoApplication.kt

That is all that is required.

cool!

thanks for this example, I'll check it out and see if I can understand it

I've only read the main kotlin website page

but I have been meaning to learn it more thoroughly to understand why people like it

There is another library that we are looking to use

https://ktor.io/

This is even more lightweight that Spring (a lot!)
