In this chapter, we learned about creating a REST API quickly with Spring JPA, Hibernate, and Spring Boot. We also learned about Reactor and its use. We created the RESTful API for our project, which we will use in the next chapter while creating the Android app.

The next chapter, which is the last chapter of this book, is about creating an Android App with Kotlin and reactive programming.

You're about to complete this book—complete learning Reactive Programming in Kotlin. Just another chapter is ahead. So, turn the page fast.
