Demo blog project using Kotlin and Spring Boot

Demo Kotlin application regarding the tutorial https://spring.io/guides/tutorials/spring-boot-kotlin/

Pros and cons

Pros

  • language is short and concise -> maintenance easier?
  • language has many nice features (see https://dev.to/martinhaeusler/kotlin---the-good-the-bad-and-the-ugly-3jfo):
    • NULL is a separate type
    • Extension functions
    • Flow Typing & Type Inference
    • Final made easy
    • Streams, streamlined
    • Iterable and Streams interoperability
    • ...
  • 100% interoperable with Java
  • translates to JVM byte code, as well as JavaScript

Cons

  • seems to be used primarily for Android development -> using Kotlin for Java / Spring web apps is an end in itself?
  • language peculiarities
    • All classes in Kotlin by default are final
    • In Kotlin, there is no static keyword
    • the primary constructor must always list (and assign) all fields
    • data classes cannot extend any base class, and are final themselves (nope, you can't use open here either)
    • abundance of Keywords
