Reactor for Reactive Programming on the JVM

Cause and effect is a process that is generally missing from many of the applications we write. In a typically application, if a value needs to be calculated or some data needs to be moved from one part of the code to another, we call a method. Consequently, we find ourselves writing synchronous and highly-coupled code.

Reactive programming, on the other hand, allows you to develop code in as asynchronous streams of data, listening for data events and reacting to them asynchronously. Reactive code is generally cleaner, more concise, and involves less coupling.

In this session, we'll explore Reactor, a foundation for reactive programming on the JVM. We'll see how to write reactive code with Reactor in both Java and Groovy as well as look at how to inject Reactor into Spring applications.
