商品描述

Discover how project Reactor enhances the reactive programming paradigm and allows you to build scalable asynchronous applications

Key Features

  • Use reactive APIs, Flux, and Mono to implement reactive extensions
  • Create concurrent applications without the complexity of Java's concurrent API
  • Understand techniques to implement event-driven and reactive applications

Book Description

Reactor is an implementation of the Java 9 Reactive Streams specification, an API for asynchronous data processing. This specification is based on a reactive programming paradigm, enabling developers to build enterprise-grade, robust applications with reduced complexity and in less time. Hands-On Reactive Programming with Reactor shows you how Reactor works, as well as how to use it to develop reactive applications in Java.

The book begins with the fundamentals of Reactor and the role it plays in building effective applications. You will learn how to build fully non-blocking applications and will later be guided by the Publisher and Subscriber APIs. You will gain an understanding how to use two reactive composable APIs, Flux and Mono, which are used extensively to implement Reactive Extensions. All of these components are combined using various operations to build a complete solution.

In addition to this, you will get to grips with the Flow API and understand backpressure in order to control overruns. You will also study the use of Spring WebFlux, an extension of the Reactor framework for building microservices.

By the end of the book, you will have gained enough confidence to build reactive and scalable microservices.

What you will learn

  • Explore benefits of the Reactive paradigm and the Reactive Streams API
  • Discover the impact of Flux and Mono implications in Reactor
  • Expand and repeat data in stream processing
  • Get to grips with various types of processors and choose the best one
  • Understand how to map errors to make corrections easier
  • Create robust tests using testing utilities offered by Reactor
  • Find the best way to schedule the execution of code

Who this book is for

If you're looking to develop event- and data-driven applications easily with Reactor, this book is for you. Sound knowledge of Java fundamentals is necessary to understand the concepts covered in the book.
