Hands-On Reactive Programming in Spring 5

Explore the reactive system and create efficient microservices with Spring Boot 2.1 and Spring Cloud

Key Features

• Understand the kind of system modern businesses require with Spring
• Gain deeper insights into reactive programming with Reactor and Spring Cloud
• Get in-depth knowledge on asynchronous and nonblocking communication with Spring 5 WebFlux

Book Description

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!

Oleh Dokuka is an experienced software engineer, Pivotal Champion, and one of the top contributors to Project Reactor and Spring Framework. He knows the internals of both frameworks very well and advocates reactive programming with Project Reactor on a daily basis. Along with that, the author applies Spring Framework and Project Reactor in software development, so he knows how to build reactive systems using these technologies.
