This course aims to teach learners how to leverage Spring's official support for Kotlin to build Spring projects more efficiently. By gradually transitioning a Spring Boot Java + Javascript project into a Spring Boot Kotlin project using WebFlux, participants will learn to use Kotlin instead of Java 8, upgrade to Spring Framework 5 and Spring Boot 2.0, switch to WebFlux and Reactive APIs, and develop the frontend with Kotlin. The teaching method includes practical demonstrations, code examples, and explanations. This course is intended for developers familiar with Spring who are interested in using Kotlin to enhance their Spring projects.
