Overview of this book

Scala Programming Projects is a comprehensive project-based introduction for those who are new to Scala. Complete with step-by-step instructions and easy-to-follow tutorials that demonstrate best practices when building applications, this Scala book will have you building real-world projects in no time. Starting with the fundamentals of software development, you’ll begin with simple projects, such as developing a financial independence calculator, and then advance to more complex projects, such as a building a shopping application and a Bitcoin transaction analyzer. You’ll explore a variety of Scala features, including its OOP and FP capabilities, and learn how to write concise, reactive, and concurrent applications in a type-safe manner. You’ll also understand how to use libraries such as Akka and Play. Furthermore, you’ll be able to integrate your Scala apps with Kafka, Spark, and Zeppelin, along with deploying applications on a cloud platform. By the end of the book, you’ll have a firm foundation in Java programming that’ll enable you to solve a variety of real-world problems, and you’ll have built impressive projects to add to your professional portfolio.

Summary


In this chapter, you learned how to create a WebSocket communication between the server and the browser.

An important piece of the system is the actor model, defined at the server level. We learned that the actor model programming paradigm is adequate as soon as we have an interaction between asynchronous systems.

You learned that a diagram of the interactions between Actors can be helpful as your system is growing. It is particularly useful when someone needs to go back to the code after being away for a while. As we are not calling methods but sending messages to ActorRef, the navigation in the IDE is not easy, so it is difficult to understand the flow just by reading the code.

Once the first steps in this framework are made, development is natural and close to real-world interaction.

We also introduced Akka. Akka is a complete framework, separated into different...
