Kotlin is a perfect replacement for Java on the server-side. People tend to use lots of additional frameworks/libraries/utilities when coding in Java. On the contrary, Kotlin provides a very lean standard library and language features that make most of the popular dependencies unnecessary or obsolete. During the last couple of years I have explored the possibilities of going with very few dependencies in real production projects, coding things like very lightweight DB access, dependency injection, and the likes that do only what you need and consume only a handful lines of code in your project, making the code easier to reason about, debug and change. During the talk, I am going to explain the code of my latest server-side app template based on Jooby and coroutines and explain how various Kotlin language features help to drastically reduce the amount of code needed on the server-side.
