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.

Spring, history, and origin of Spring

What is Spring? We cannot give a short answer. It's really tough to define Spring in a sentence or two. Many people may say Spring is a framework, but this would be also an understatement for Spring, as it may also be called a framework of frameworks. Spring provides you with a lot of tools, such as DI (dependency injection), IoC (Inversion of Control), and AOP (Aspect-oriented programming). While we can use Spring in almost any type of Java or Kotlin JVM application, it is most useful while developing web applications on top of the Java EE platform. Before moving into the details of Spring, we should first understand from where and why Spring originated and how it has evolved.

The origin and history of Spring

It has been more than two decades (around 22 years) since Java has been around. For enterprise application development, Java introduced a few technologies that were heavyweight and were very complex enough.

In 2003, Rod Johnson created Spring as an...
