If you think about Kotlin you could probably think about Android and mobile development.
It’s true. When Google announced Kotlin as the preferred language for the Android platform, its overall popularity increased sharply.
According to The State of Developer Ecosystem 2019, the survey made by JetBrains (Kotlin language creators), 62% of Kotlin-based apps were mobile. But 41% of Kotlin projects were related to web back-end development.
Indeed, Kotlin may be a good choice for server-side development. Among other frameworks, Kotlin is one of the officially supported languages of the Spring Framework.
In this text, I’d like to show you how easy it is to create a Spring application using Kotlin. I’m going to implement a simple CRUD REST API with Spring Boot and MongoDB as a database using Kotlin as a language.
So, get started with implementation and try it yourself.
