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.

Implementing the transaction batch producer


In this section, we will first discuss how to call a REST API to fetch BTC/USD transactions. Then we will see how to use Spark to deserialize the JSON payload into a well-typed distributed Dataset.

After that, we will introduce the parquet format and see how Spark makes it easy to save our transactions in this format.

With all of these building blocks, we will then implement our program in a purely functional way using the Test-Driven-Development (TDD) technique.

Calling the Bitstamp REST API

Bitstamp is a cryptocurrency exchange that people use to trade a cryptocurrency, such as bitcoin, for a conventional currency, such as US dollar or euro. One of the good things about Bitstamp is that it provides a REST API, which can be used to get information about the latest trades, and can also be used to send orders if you have an account.
