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.

Chapter 8. Online Shopping - User Interface

In this chapter, we are going to use Scala.js to build the user interface. In this interface, you can select a product to add to your cart, update the number of products that you wish to buy, and remove them from the cart if needed.

Scala.js is a project initiated by Sebastien Doeraene back in 2013. This project is mature and provides a clean way to build frontend applications. Indeed, you can code with a strongly-typed system to avoid stupid mistakes, but this is not only for strong typing; the code—written in Scala—is compiled into a highly efficient JavaScript. It can interoperate with all of the JavaScript frameworks. Moreover, the code can be shared between the front-end and the back-end developers. This feature simplifies communication between developers, as they are using the same concepts and classes.

Thanks to its interoperability, there are multiple ways to use Scala.js. You can use an HTML template and adapt it to interoperate with Scala...
