Reactive Programming in Kotlin

By: Rivu Chakraborty

Overview of this book

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.

In this chapter, we learned about what reactive programming is and the reasons we should learn it. We also started with coding. The reactive coding pattern may seem new or somehow uncommon, but it is not that hard; while using it, you just need to declare a few more things.

We learned about observable and its use. We also got introduced to subject and map, which we will learn in depth in the later chapters.

We will continue with ReactiveCalculator example in the later chapters and see how we can optimize and enhance this program.

The three examples presented in this chapter may seem a bit confusing and complex at first, but they're really simple, and they will become familiar to you as you proceed with this book.

In the next chapter, we will learn more about functional programming and functional interfaces in RxKotlin.
