Spring Coroutines official support allows to go Reactive with Kotlin,

Deepdive into Reactive Spring with Coroutines and Kotlin Flow

Deep Dive
Programming languages

Spring Coroutines official support allows to go Reactive with Kotlin, WebFlux, RSocket and R2DBC (Reactive SQL) with a great balance between imperative and declarative programming, and can even be used outside of the JVM.
In this deep dive session, we are going to take a journey across building step by step a distributed chat application with Spring Boot 2.2 for the backend and Kotlin/JS for the frontend to experiment concretely with these topics:

  • Main reasons for switching from Java to Kotlin
  • State of Kotlin support in Spring Boot 2.2
  • The 3 pillars of Coroutines 1.3: suspending functions, structured concurrency and the brand new Flow type
  • Coroutines support in Spring WebFlux with @Controller and the router DSL
  • Using Coroutines in the browser with Kotlin/JS
  • Building a Reactive messaging infrastructure with RSocket
  • Reactive SQL with R2DBC
  • Configuring Spring Boot explicitly with Kofu experimental DSL from Spring Fu incubator
