Reactive Streams in Java

Introduction to Reactive Streams in Java 8, 9, and Beyond

About the Book

This book is now for sale on Apress and will be published early 2019!

Reactive Streams are a standard approach to handling concurrency in modern applications. The Java 9 release includes new support for reactive streams. This book attempts to provide an easy introduction to Reactive Streams in Java including in depth introductions to RxJava, Akka Streams, and Reactor and how they can be used. It covers:

  • Building apps for Android with RxJava
  • Spring Boot with Reactor and reactive-mongo
  • Build a websocket-based chat server with Akka HTTP with Akka Streams

This book will cover everything you need to know about existing projects and how they translate in Java 9, 10 and 11.

This book uses a progressive publishing model. As the book grows, so does the price. This encourages early adopters.

When our freedoms in the networked world come under attack, the Electronic Frontier Foundation (EFF) is the first line of defense. EFF broke new ground when it was founded in 1990—well before the Internet was on most people's radar—and continues to confront cutting-edge issues defending free speech, privacy, innovation, and consumer rights today. From the beginning, EFF has championed the public interest in every critical battle affecting digital rights.
