Chapter 1, The Power of Kotlin, is the introductory chapter. It covers why Kotlin is quickly becoming a force to reckon with. Kotlin positions itself as the smart choice to the various stakeholders, such as the programmer, the manager, and the businesses. The chapter looks at the technology and business reasons that fuel the adoption of Kotlin. Chapter 2, Geospatial Messenger – Spring Boot, covers the use of Spring Boot technology to create robust server-side applications. Spring is one of the most well-known and well-respected server-side frameworks in the Java space, and Spring Boot is its less verbose and more powerful version. This chapter covers how a Geospatial Messenger application is created with Spring Boot technology using the Kotlin language. Chapter 3, Social Media Aggregator Android App, is using Kotlin to create native Android apps. With Google officially recognizing Kotlin's use to develop Android apps, this is the most widespread application to use the Kotlin language. Today's mobile apps hardly work in isolation. They work with a server. This common scenario is illustrated with a social media aggregator app. Chapter 4, Weather App Using Kotlin for JavaScript, explores the use of Kotlin to create rich internet apps that work within the browser. JavaScript is clearly the de facto standard language that works across all the browsers. However, Kotlin is clearly superior to JavaScript in many ways. This chapter shows how one can have the best of both worlds by doing the coding in Kotlin and, then, transpiling the code to JavaScript so that it works with the browsers seamlessly. The example that we will build is a simple weather application. Chapter 5, Chat Application with Server-Side JavaScript Generation, explores how the same facility of transpiling Kotlin to Javascript can be used on the server side. JavaScript is used on the server side within the popular and fast Node.js framework. Kotlin can be used to create Node.js applications, as the JavaScript code that runs with Node.js can be generated from it. This chapter shows how to do so by creating a simple chat application. Chapter 6, News Feed – REST API, covers the use of Kotlin specifically to create REST services. We will develop a News Feed application with the Ktor framework, which is a leading Kotlin-only framework used for server-side applications. Chapter 7, CSV Reader in Kotlin Native, explores a bleeding edge technology—Kotlin Native—which is about compiling Kotlin code directly to platform-specific executables. Although not mature, Kotlin Native is worth watching as it quickly marches to its promise of becoming the only language to create native applications across disparate platforms such as iOS and Raspberry Pi. In this chapter, a small CSV reader utility is built with Kotlin/Native. Chapter 8, Dictionary Desktop Application - Tornado FX, is about using Kotlin to create a cross-platform desktop application based on Java technology. Tornado FX is a Kotlin-specific framework, which is based on the most advanced Java GUI framework, that is, Java FX. This chapter illustrates the power of Tornado FX with a dictionary application.

Mobile DevOps is the future of continuous integration and continuous delivery for mobile application development, and is a very important requirement of today's fast-paced development culture. While DevOps has been implemented and adopted by most fast-growing development teams today, mobile DevOps is yet to be used by the majority of the mobile development world. It is something that can improve integration and delivery, as well as provide a greater feedback mechanism and early defect capturing tools. Mobile DevOps comes with its own implementation challenges, and with various mobile platforms out there on millions of devices and with different aspect ratios, it is only becoming more important to use tools that streamline testing on physical devices and delivery to customers while providing a quick feedback mechanism to developers. In this book, we'll be using Xamarin to explore mobile application development fundamentals and tools. Xamarin is a cross-platform mobile application development framework from Microsoft that can be used to create iOS, Android, and Windows apps using a shareable code base and design. Apart from Xamarin, we'll be using other tools from Microsoft's tool belt, such as Xamarin Test Cloud and Visual Studios Team Services, to dive deep into the different phases of mobile DevOps. The main motivation to use Xamarin is its ability to develop cross-platform applications and applications with great integration with Microsoft's other widely used tools for different phases of the application development cycle. By the end of this book, you should not only be accustomed with mobile DevOps and mobile application development, but you should also be able to implement, configure, and troubleshoot each and every step involved in the mobile DevOps life cycle in your new and/or existing mobile application projects using the popular tools that are available.
