Description

For developers who are working with design patterns in Kotlin, this practical guide offers an opportunity to put their knowledge into practice. The book covers classical and modern design patterns, and provides a hands-on approach to implementation, along with associated methodologies. The third edition stays current with Kotlin updates, spanning from version 1.6 onwards, and offers in-depth insights into topics like structured concurrency and context receivers. The book starts by introducing essential Kotlin syntax and the significance of design patterns, covering classic Creational, Structural, and Behavioral patterns. It then progresses to explore functional programming, Reactive, and Concurrent patterns, including detailed discussions on coroutines and structured concurrency. As you navigate through these advanced concepts, you'll enhance your Kotlin coding skills. The book also delves into the latest architectural trends, focusing on microservices design patterns and aiding your decision-making process when choosing between architectures. By the end of the book, you will have a solid grasp of these advanced concepts and be able to apply them in your own projects.

Who is this book for?

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. Familiarity with classical design patterns from your language of choice would be helpful, but you'll still be able to follow along if you code in other languages

What you will learn

Utilize functional programming and coroutines with the Arrow framework

A recent project change has required me to learn Kotlin over the last couple of months. I'm experienced with languages such as C, C++, Java, Swift, and Python, and wanted a book that didn't waste time explaining to me what loops are, but instead showed me how the unique language features could be used to implement an impressively large number of software design patterns.The first chapter gives a good overview of the everyday elements of the language, like how to define vals and vars, functions, classes, create controls flows and loops, and assignments. The following chapters then dive into how to use Kotlin exclusive features to implement design patterns ranging from the original selection from the Gang of Four's book to more modern ones.The examples used throughout the book are interesting and entertaining, often showing multiple ways of implementing a pattern in Kotlin.Overall an excellent book that has furthered my understanding better and quicker than any other resource I've found.

Having delved into Kotlin a few years ago, I was excited to get back into the language with the help of "Kotlin Design Patterns and Best Practices." This book has proven to be an invaluable resource, especially with its comprehensive showcase of the latest developments in Kotlin.The book starts with a concise refresher on Kotlin basics, which is perfect for someone like me who needed to brush up on the essentials. It quickly transitions from the fundamentals to an in-depth exploration of design patterns, tailored specifically for Kotlin. This approach ensures that you're not bogged down with unnecessary basics, making it an excellent resource for those already familiar with other programming languages.One of the standout features of this book is its practical approach to design patterns. Each pattern is introduced with clear explanations and illustrated with engaging examples. I appreciated how the authors didn't just present a one-size-fits-all solution but instead explored multiple ways to implement each pattern in Kotlin. This method not only solidified my understanding of design patterns but also showcased the unique features of Kotlin that make these implementations more efficient and elegant.What sets this book apart is its focus on best practices. The authors delve into the reasoning behind each best practice, explaining the trade-offs and benefits. This thorough examination helped me understand why certain approaches are favored in Kotlin, which has greatly improved my coding practices.The book doesn't just stop at traditional design patterns; it also covers modern patterns and practices. The sections on functional programming and concurrency were particularly enlightening. Learning how to effectively use Kotlin's coroutines for managing concurrent tasks has been a game-changer for me. The final chapters on building microservices using popular frameworks provided a practical perspective on how to apply these patterns in real-world applications.Overall, "Kotlin Design Patterns and Best Practices" is an excellent resource for both revisiting and advancing your Kotlin skills. It has equipped me with a deeper understanding of how to leverage Kotlin's features to write more robust and maintainable code. Whether you're getting back into Kotlin or looking to enhance your knowledge, this book is a highly recommended read.

Despite having no professional programming experience (yet) and having mostly programmed with Python, when I got an opportunity to get an early review copy of 3rd edition of Alexey Soshin’s book in exchange for a little review, I decided to jump in. Kotlin is enticing after all: it’s a bit functional and it targets the JVM! Design Patterns -tag in the book’s title almost sells the book short as the book is about much more than just the classic Gang of Four methods. After launching with Kotlin fundamentals recap, the book is in (roughly) equal parts about the classical design patterns (Section 1), functional and concurrent patterns (Section 2) and practical applications of all of them (Section 3). The Kotlin fundamentals -part has a specific approach of comparing Kotlin’s syntax to Java. Java comparisons don’t necessarily feel helpful for a person with most experience with Python, but they do make me appreciate Kotlin’s more concise syntax. For me, the most interesting part of this section were the serious considerations about immutability. Kotlin has strong ties to two worlds, OOP because of connection to Java and functional paradigm because of languages philosophy and this shows in the approach. The classic Gang of Four design patterns are examined in the book thoroughly and with good examples. As expected, specific Kotlin methods are described in conjunction with use of each design pattern. Alexey Soshin has clearly worked with each of the design patterns in order to break through levels of abstraction which easily make programming concepts feel disconnected from reality. I am no expert in using design patterns, but this section seems solid and worth studying with an actual project at hand. Section 2 starts with a practical observation that functional programming patterns are particularly adept at handling parallel tasks. I think this is a good take and it’s a smart idea to learn using immutable structures and other functional programming tools from the start when learning parallel and concurrent programming. Multithreaded design is explained with practical examples of potential pitfalls such as heavy memory usage and slow processes when concurrency is not sufficient. One chapter is dedicated to enhancing coroutines with reactive principles, higher-order functions and concurrent data structures. Concurrent design patterns explored in this section include: deferred value, barrier, scheduler, pipeline, fan-out, fan-in, racing, mutex and sidekick. Section 3 dives deep into idioms and anti-patterns as well few specific libraries. Functional library Arrow gets its own chapter as well as more hands-on chapters with Ktor and Vert.x. Book ends with Assessments -chapter which presents FAQ of topics presented in the book. All in all the book seems to be a well thought out exploration into its topics!
