Hands-On Reactive Programming in Spring 5

By: Oleh Dokuka, Igor Lozynskyi

Overview of this book

These days, businesses need a new type of system that can remain responsive at all times. This is achievable with reactive programming; however, the development of these kinds of systems is a complex task, requiring a deep understanding of the domain. In order to develop highly responsive systems, the developers of the Spring Framework came up with Project Reactor. Hands-On Reactive Programming in Spring 5 begins with the fundamentals of Spring Reactive programming. You’ll explore the endless possibilities of building efficient reactive systems with the Spring 5 Framework along with other tools such as WebFlux and Spring Boot. Further on, you’ll study reactive programming techniques and apply them to databases and cross-server communication. You will advance your skills in scaling up Spring Cloud Streams and run independent, high-performant reactive microservices. By the end of the book, you will be able to put your skills to use and get on board with the reactive revolution in Spring 5.1!

Summary

In this chapter, we have revisited a few well-known design patterns by GoF—including Observer, Publish-Subscribe, and Iterator to build the basis of reactive programming. We have written a few implementations to review both the strong and weak sides of the instruments we already have for asynchronous programming. We have also leveraged Spring Framework support for Server-Sent Events, WebSockets, and also played with Event-Bus provided by Spring. Also, we have used Spring Boot and start.spring.io for fast application bootstrapping. Even though our examples were pretty simple, they demonstrated the potential issues that arise from immature approaches that are used for asynchronous data processing.

We also looked at reactive programming's history to highlight architectural problems, which reactive programming was invented to fight against. In this context...
