This book is all about how to develop Reactive systems using the Functional Reactive Programming (FRP) style. It is a combination of both Functional Programming (FP) and Reactive Programming(RP) styles.
Scala is a multi-paradigm language that supports both FP and RP very well. It also has an AP (Asynchronous Programming) API. It supports Concurrency and true Parallelism using the Future API and Akka's Actor Model.
We will develop a couple of Reactive microservices using Lightbend's Reactive Platform, that is, Scala, Akka, Akka Streams, Play Framework, and Lagom Framework. We will deploy and test our Reactive system into Lightbend's ConductR sandbox environment.
