Scala Reactive Programming

By: Rambabu Posa

Overview of this book

Reactive programming is a scalable, fast way to build applications, and one that helps us write code that is concise, clear, and readable. It can be used for many purposes such as GUIs, robotics, music, and others, and is central to many concurrent systems. This book will be your guide to getting started with Reactive programming in Scala. You will begin with the fundamental concepts of Reactive programming and gradually move on to working with asynchronous data streams. You will then start building an application using Akka Actors and extend it using the Play framework. You will also learn about reactive stream specifications, event sourcing techniques, and different methods to integrate Akka Streams into the Play Framework. This book will also take you one step forward by showing you the advantages of the Lagom framework while working with reactive microservices. You will also learn to scale applications using multi-node clusters and test, secure, and deploy your microservices to the cloud. By the end of the book, you will have gained the knowledge to build robust and distributed systems with Scala and Akka.

Reactive System's best practices and tools

In this section, we will briefly discuss a couple of useful best practices and tools we need to consider in designing and developing Reactive Systems.


Use Akka Toolkit, Play Framework, and/or Lagom Framework to develop your Reactive Systems (Reactive Microservices or Reactive Web Applications) because they are Reactive by design.

Akka Toolkit supports Reactive Design Patterns by design. Play Framework is developed using Akka Toolkit under the hood. In the same way, Lagom Framework is developed by using Akka Toolkit and Play Framework under the hood.

Akka Toolkit supports the Akka Streams API (which implements Reactive Streams), for data streaming.
