Part 3. Reactive Spring

In part 3, we’ll explore the support for reactive programming in Spring. Chapter 11 discusses the essentials of reactive programming with Project Reactor, the reactive programming library that underpins Spring’s reactive features. We’ll then look at some of Reactor’s most useful reactive operations. In chapter 12, we’ll revisit REST API development, introducing Spring WebFlux, a web framework that borrows much from Spring MVC while offering a new reactive model for web development. Chapter 13 takes a look at writing reactive data persistence with Spring Data to read and write data to Cassandra and Mongo databases. Chapter 14 rounds out part 3 by looking at RSocket, a communication protocol that enables a reactive alternative to HTTP.
