In this talk, I will explain why Spring ❤ Kotlin and how you can leverage Spring official support for Kotlin (in Framework, Boot, Data) to build your next Spring project more efficiently and with more pleasure.

I will describe gradually how you can transform your Spring Boot 1.0 Java + Javascript project into a Spring Boot 2.0 pure Kotlin project running on top of the new WebFlux functional web framework:

Step 1: Why Kotlin and how to use Kotlin instead of Java 8
Step 2: Upgrade to Spring Framework 5 and Spring Boot 2.0
Step 3: Switch from Spring MVC to WebFlux and Reactive APIs
Step 4: Use WebFlux functional API
Step 5: Frontend development with Kotlin instead of JavaScript/TypeScript
