Kotlin Design Patterns and Best Practices - Second Edition: Build scalable applications using traditional, reactive, and concurrent design patterns in Kotlin

by Alexey Soshin, Anton Arhipov (Foreword)

Future-proof your applications with best practices and design patterns in Kotlin This book shows you how easy it can be to implement traditional design patterns in the modern multi-paradigm Kotlin programming language, and takes you through the new patterns and paradigms that have emerged. This second edition is updated to cover the changes introduced from Kotlin 1.2 up to 1.5 and focuses more on the idiomatic usage of coroutines, which have become a stable language feature. You'll begin by learning about the practical aspects of smarter coding in Kotlin, as well as understanding basic Kotlin syntax and the impact of design patterns on your code. The book also provides an in-depth explanation of the classical design patterns, such as Creational, Structural, and Behavioral families, before moving on to functional programming. You'll go through reactive and concurrent patterns, and finally, get to grips with coroutines and structured concurrency to write performant, extensible, and maintainable code. By the end of this Kotlin book, you'll have explored the latest trends in architecture and design patterns for microservices. You'll also understand the tradeoffs when choosing between different architectures and make informed decisions. This book is for developers who want to apply design patterns they've learned from other languages in Kotlin and build reliable, scalable, and maintainable applications. You'll need a good grasp on at least one programming language before you get started with this book. Java or design patterns will be particularly useful, but you'll still be able to follow along if you code in other languages.

The book is easy to read and presents many important aspects of kotlin language and how they apply to programming scenarios. I consider it an interesting read for someone, like me, that already knows the language and it's trying to improve.
Still, some examples were too simple or not really well formulated, in my opinion. Especially the part about the classic design patterns risks to result confusing to someone that doesn't have experience with the actual patterns, especially because the patterns are described in a confusing way.
There are other code examples as well that are not always great or not optimal.
Overall, a good book to read.

The last two chapters were kind of meh but I enjoyed the rest and learned a lot

I'm sure the author has put some effort into this. Had he put it up as a blog post, or distributed it for free, I would not say what I'm about to say: This book is basically bad. It's hardly even formatted. I found it really hard to turn the pages because it lacked good examples, decent writing and it was a serious eye sore. I'm sorry, but this should have been out there for free. Not worth my time or money.
