Preface

Spring is the most popular framework for web development and, every year, more and more developers are getting involved in Spring development. Spring Framework makes it possible to develop applications for the web, especially RESTful and other types of services. So far, all development has been undertaken in Java. Recently, Kotlin has become very popular! Due to this, and the huge growth of the Kotlin community, we decided to introduce you to Spring development by using Kotlin as the primary development programming language.

With Kotlin, you can do everything you could do with Java, but with more joy and fun! We will show you how to play with Spring and Kotlin and how to create amazing things! Take your seat and get ready for an amazing journey!
