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.

Managing Microservices in ConductR

In this chapter, we will discuss one of the important tools of Lagom Reactive Platform. It has two kinds of environments:

  • The Lagom Production Environment
  • The Lagom Development Environment

If we want to use the Production Environment, we need Lightbend's paid license. As it's just for experimental and educational purposes, we will use the Development Environment in this chapter.

Lagom Reactive Platform's Development Environment is ConductR sandbox. In this chapter, we will set up our ConductR Sandbox Local Development Environment and deploy our WF Reactive System into this environment and test it.

Refer to ConductR's documentations at for more information.

As of now, we have ConductR 2.2.x as the latest and the most stable version of ConductR.

In this chapter, you will learn...
