Learn Kotlin Programming - Second Edition

By: Stephen Samuel, Stefan Bocutiu

Overview of this book

Kotlin is a general-purpose programming language used for developing cross-platform applications. Complete with a comprehensive introduction and projects covering the full set of Kotlin programming features, this book will take you through the fundamentals of Kotlin and get you up to speed in no time. Learn Kotlin Programming covers the installation, tools, and how to write basic programs in Kotlin. You'll learn how to implement object-oriented programming in Kotlin and easily reuse your program or parts of it. The book explains DSL construction, serialization, null safety aspects, and type parameterization to help you build robust apps. You'll learn how to destructure expressions and write your own. You'll then get to grips with building scalable apps by exploring advanced topics such as testing, concurrency, microservices, coroutines, and Kotlin DSL builders. Furthermore, you'll be introduced to the kotlinx.serialization framework, which is used to persist objects in JSON, Protobuf, and other formats. By the end of this book, you'll be well versed with all the new features in Kotlin and will be able to build robust applications skillfully.

Why microservices?

While you might have been put off by the list of drawbacks presented earlier, you should keep in mind that there are real benefits for taking this approach; if it wasn't paying off, people wouldn't do it.

One of the main benefits of a design like this is breaking down the complexity of a monolithic application. It will end up providing a finite set of services, allowing one to achieve the same functionality while having code that is easier to understand, maintain, and evolve.

You will find that, with the microservices approach, you are not restricted to a specific technology and language. Because a service can be developed independently by one team, its members get to decide on the tech stack that makes the most sense for the problem at hand. How many times did you want to use a newer framework and/or language because it adds value, but you have been...
