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.

In this chapter, we learned about Lightbend's Development Environment—ConductR Sandbox. ConductR is a RAM (Reactive Applications Manager). It provides a CLI (Command-Line Interface) to create our services bundles, and load and run those bundles in the Sandbox environment.

We discussed how to set up the local ConductR Sandbox environment and its main components.

Lightbend ConductR supports two kinds of APIs—the Bundle API and Control API.

We converted our WF Reactive System components to match the ConductR Sandbox environment, then created bundles and deployed them into Sandbox successfully. Finally, we tested our WF Reactive System.

In the next chapter, we are going to discuss the Reactive design principles, patterns, and some of the useful best practices.
