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.

Reasons to use libraries

Writing software applications will inevitably bring developers to the point where they will have to implement something that already exists. Reinventing the wheel is generally a bad idea unless we have some extremely specific and strict requirements that no library in the world satisfies, or if there is good reason not to include a specific dependency in our project.

People write libraries to deal with all kinds of problems in software. In a community such as the open source community, libraries are shared and everyone can use or contribute to them. This brings a lot of benefits, and the main benefit is that code becomes more mature, better tested, and more reliable. However, sometimes this also makes things harder—many people will create the same library and it becomes difficult to understand which one is the most suitable.
