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.
Table of Contents (16 chapters)


In this chapter, we have discussed the Play Framework basics, looking at its benefits and features. We have discussed the Play MVC components, such as Views, Controllers, Models, Routes, and more.

We started with the basic Play HelloWorld web application and extended it to different Play features, such as DI, Forms, file upload, and more.

As we discussed in Chapter 3, Asynchronous Programming with Scala, Play Framework applications use Scala Futures extensively. We have converted our simple example to use Futures.

We have discussed Play Framework and its component architecture in detail with some simple diagrams, and we have also explained the Play Framework SBT project structure.

So far, in this book, we have discussed many concepts, such as Scala Functional Programming, Asynchronous Programming, Akka Toolkit, and Play Framework. It's good to start building our Weather...
