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.

At some point, we will need to have a class that is responsible for the workflow of the user experience. For example, when a user clicks on the Add to cart button, the product has to be added to the cart at the server level and the user interface has to be updated.

The UI manager takes responsibility for managing the workflow of the user experience, handling all communication with the server when needed, and is used as an entry point to start the Scala.js code. This is the main entry point of our client application when the application is executed in the browser.

For communicating with the server, we are going to use jQuery. This JavaScript library is widely used and is a reference in the JavaScript world.

This is one of the advantages of Scala.js. We can use existing JavaScript libraries, such as jQuery, from Scala. To use existing JavaScript libraries, we only need to define an interface, which is called a facade in Scala.js. The facade can be seen as an interface...
