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.

Summary


In this chapter, we learned about Observables and Observers and how to use them. We worked with several examples to get our grips strong on them. We learned that there are two categories of ObservablesHot Observables and Cold Observables. We also learned about several Subject and its variant. Several Subject are basically a combination of Observables and many Observer.

While Observables provide us with great flexibilities and power, it too has some disadvantages, such as backpressure. Curious about it? Want to know more about the disadvantages of Observables and how to overcome them? Rush to the fourth chapter then.
