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.

Configurating Akka applications

There are many properties that need to be set in the Akka application, either programmatically or via configuration. Configuration is the recommended approach to set the properties in the Akka application.

Getting ready

To step through this recipe, we just need to import the Hello-Akka project; other prerequisites are the same as earlier. By default, configuration is read from application.conf, but it can be read from any .conf file. Usually, we put all conf files in the project resources folder. 

How to do it…

  1. Create a conf file, say, akka.conf, in the project's src/main/resources folder.



  1. For example, add the following properties to akka.conf:
        myactor {
  1. Create an ActorWithConfig.scala file in the com.packt.chapter5 package.
  2. Add the following import to the top of the file:
        import{Props, Actor, ActorSystem}
        import com.typesafe.config.Config
        import com.typesafe...
