Overview of this book

Kotlin is a powerful language that has applications in a wide variety of fields. It is a concise, safe, interoperable, and tool-friendly language. The Android team has also announced first-class support for Kotlin, which is an added boost to the language. Kotlin’s growth is fueled through carefully designed business and technology benefits. The collection of projects demonstrates the versatility of the language and enables you to build standalone applications on your own. You’ll build comprehensive applications using the various features of Kotlin. Scale, performance, and high availability lie at the heart of the projects, and the lessons learned throughout this book. You’ll learn how to build a social media aggregator app that will help you efficiently track various feeds, develop a geospatial webservice with Kotlin and Spring Boot, build responsive web applications with Kotlin, build a REST API for a news feed reader, and build a server-side chat application with Kotlin. It also covers the various libraries and frameworks used in the projects. Through the course of building applications, you’ll not only get to grips with the various features of Kotlin, but you’ll also discover how to design and prototype professional-grade applications.

Multiplatform Kotlin

A Kotlin multiplatform project allows you to compile the same code for multiple target platforms. Currently, supported target platforms are JVM and JS with Native, which is still under development and will be added later.


Multiplatform Kotlin is still under review, similarly to Kotlin Native.

Project structure

A multiplatform project consists of three types of module—a common module, a platform module, and a regular module. Let's look at them in detail.

Common module

common module contains platform-independent code, meaning it is not specific to any platform, as well as declarations without the implementation of platform-dependent APIs. Those declarations allow common code to depend on platform-specific implementations. This module is shared across other modules and is common between them, hence the name common

A common module can depend only on other common modules and libraries, including the kotlin-stdlib-common Kotlin standard library .
