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.

Deploying the WF Reactive System on ConductR

In this section, we will discuss how to start the ConductR Sandbox environment and how to bundle, load, and run our Reactive System components, such as wf-producer-impl, wf-consumer-impl, and wf-frontend.

Do we need to bundle and deploy only our Impl components into the ConductR Sandbox environment? How about the API components? The answer is yes, we need to deploy only Impl components into the ConductR Sandbox environment, but not the API components.

Starting ConductR Sandbox with multinodes

ConductR Sandbox runs the following command syntax:


We have already discussed how to start Sandbox in the previous section, using the following...
