Scala Design Patterns - Second Edition

By: Ivan Nikolov

Overview of this book

Design patterns make developers’ lives easier by helping them write great software that is easy to maintain, runs efficiently, and is valuable to the company or people concerned. You’ll learn about the various features of Scala and will be able to apply well-known, industry-proven design patterns in your work. The book starts off by focusing on some of the most interesting and latest features of Scala while using practical real-world examples. We will be learning about IDE’s and Aspect Oriented Programming. We will be looking into different components in Scala. We will also cover the popular "Gang of Four" design patterns and show you how to incorporate functional patterns effectively. The book ends with a practical example that demonstrates how the presented material can be combined in real-life applications. You’ll learn the necessary concepts to build enterprise-grade applications. By the end of this book, you’ll have enough knowledge and understanding to quickly assess problems and come up with elegant solutions.

Functional Design Patterns – the Deep Theory

The Scala programming language is a hybrid between a functional and object-oriented language. Most of the object-oriented design patterns are still applicable. However, in order to facilitate the full power of Scala, you also need to be aware of the purely functional aspects of it. When using the language and reading tutorials or best practices, developers will most likely notice terms such as monoids, monads, and functors appearing more often as the problems become harder or the solutions are desired to be more elegant. In this chapter, we will focus on the following functional design patterns:

  • Monoids
  • Functors
  • Monads

There are a lot of resources on the preceding topics all over the internet. The problem is that many of them are extremely theoretical and hard to understand by someone who is not really familiar with mathematics...
