▶Book Description
In today’s app-driven era, when programs are asynchronous, and responsiveness is so vital, reactive programming can help you write code that’s more reliable, easier to scale, and better-performing. Reactive programming is revolutionary.
With this practical book, Kotlin developers will first learn how to view problems in the reactive way, and then build programs that leverage the best features of this exciting new programming paradigm. You will begin with the general concepts of Reactive programming and then gradually move on to working with asynchronous data streams. You will dive into advanced techniques such as manipulating time in data-flow, customizing operators and provider and how to Use the concurrency model to control asynchronicity of code and process event handlers effectively.
You will then be introduced to functional reactive programming and will learn to apply FRP in practical use cases in Kotlin. This book will also take you one step forward by introducing you to spring 5 and spring boot 2 using Kotlin. By the end of the book, you will be able to build real-world applications with reactive user interfaces as well as you’ll learn to implement reactive programming paradigms in Android.
▶What You Will Learn
⦁ Learn about reactive programming paradigms and how reactive programming can improve your existing projects
⦁ Gain in-depth knowledge in RxKotlin 2.0 and the ReactiveX Framework
⦁ Use RxKotlin with Android
⦁ Create your own custom operators in RxKotlin
⦁ Use Spring Framework 5.0 with Kotlin
⦁ Use the reactor-kotlin extension
⦁ Build Rest APIs with Spring,Hibernate, and RxKotlin
⦁ Use testSubscriber to test RxKotlin applications
⦁ Use backpressure management and Flowables
▶Key Features
⦁ Learn how to solve blocking user experience with Reactive Programming and get deep insights into RxKotlin
⦁ Integrate Reactive Kotlin with Spring and build fantastic Android Apps with RxKotlin and RxAndroid
⦁ Build reactive architectures that reduce complexity throughout the development process and make your apps(web and Android) scalable
▶Who This Book Is For
This book is for Kotlin developers who would like to build fault-tolerant, scalable, and distributed systems. A basic knowledge of Kotlin is required, but no prior knowledge of reactive programming.
▶What this book covers
⦁ Chapter 1, A Short Introduction to Reactive Programming, helps you understand the context, thinking pattern, and principles of reactive programming.
⦁ Chapter 2, Functional Programming with Kotlin and RxKotlin, chapter walks you through the essential concepts of functional programming paradigms and their possible implementations on Kotlin so that you can understand functional reactive programming easily.
⦁ Chapter 3, Observables, Observers, and Subjects, enables you to gain a grip on the base of RxKotlin—.Observables, Observers, and Subjects lay at the core of RxKotlin.
⦁ Chapter 4, Introduction to Backpressure and Flowables, introduces you to Flowables, which enable you to use Backpressure—.a technique in RxKotlin that prevents producers from outpacing consumers.
⦁ Chapter 5, Asynchronous Data Operators and Transformations, introduces you to operators in RxKotlin.
⦁ Chapter 6, More on Operators and Error Handling, gets your grip stronger on operators, and introduces how to combine producers and how to filter them with operators. This chapter will also help you handle errors more efficiently in RxKotlin.
⦁ Chapter 7, Concurrency and Parallel Processing in RxKotlin with Schedulers, enables you to leverage the benefits of Schedulers to achieve concurrent programming.
⦁ Chapter 8, Testing RxKotlin Applications, walks you through the most crucial part of application development—.testing—.which is a bit different in RxKotlin as reactive programming defines behaviors instead of states. This chapter starts with the basics of testing, enabling you to learn testing from scratch.
⦁ Chapter 9, Resource Management and Extending RxKotlin, helps you learn how to manage resources in Kotlin—.resources could be database instances, files, HTTP accesses, or anything that needs to be closed. You will also learn how to create your own custom operators in RxKotlin in this chapter.
⦁ Chapter 10, Introduction to Web Programming with Spring for Kotlin Developers, gets you started with Spring and Hibernate so that you can leverage its benefits while writing APIs in Kotlin.
⦁ Chapter 11, REST APIs with Spring JPA and Hibernate, introduces you to the Reactor framework, the reactor-kotlin extension, so that you can apply reactive programming with Spring in Kotlin.
⦁ Chapter 12, Reactive Kotlin and Android, the last chapter of this book, gets you started with reactive programming in Android with Kotlin.
