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.

Summary

In this chapter, we discussed what the Akka Toolkit is and its features and benefits. We developed a couple of simple examples.

We also discussed how the Akka Toolkit eases the development of Reactive systems. Akka is an open source runtime and middleware framework designed to develop distributed and Reactive System, easily.

Akka is a toolkit, not a framework. By design, it supports distributed and Reactive features. It is not just an implementation of the Actor Model. It supports many other features, in terms of Akka Modules or Akka Extensions.

Let's continue our journey into building a WF Reactive System using the Lightbend Reactive Ecosystem in the coming chapters.
