Akka Cookbook

By: Vivek Mishra, Héctor Veiga Ortiz

Overview of this book

Akka is an open source toolkit that simplifies the construction of distributed and concurrent applications on the JVM. This book will teach you how to develop reactive applications in Scala using the Akka framework. This book will show you how to build concurrent, scalable, and reactive applications in Akka. You will see how to create high performance applications, extend applications, build microservices with Lagom, and more. We will explore Akka's actor model and show you how to incorporate concurrency into your applications. The book puts a special emphasis on performance improvement and how to make an application available for users. We also make a special mention of message routing and construction. By the end of this book, you will be able to create a high-performing Scala application using the Akka framework.

Building JSON support with Akka HTTP

As seen in the previous recipes, Akka HTTP has great integration for marshaling and unmarshaling. This is especially true if we want to serialize and deserialize JSON entities. Akka HTTP was initially developed under a different project named Spray. Spray had similar modules as Akka HTTP does. However, Spray had a JSON serialization library called spray-json. This module was not ported to Akka HTTP and stayed spray-json. This was because the Akka team did not want to own a serialization library, but provide means to integrate any marshaling library into Akka HTTP.

In this recipe, we will see how to easily integrate spray-json into our application to serialize and deserialize classes into and from JSON.

Getting ready

To step through this recipe, we need to import the Hello-Akka project and the required Akka HTTP dependency we added in the previous recipe. Also, we will include the required spray-json dependency.
