Reactive Programming with RxJS: Untangle Your Asynchronous JavaScript Code

by Sergi Mansilla

Reactive programming is revolutionary. It makes asynchronous programming cleaner, intuitive, and robust. Discover how to use the RxJS library to write programs in a simpler way, unifying asynchronous mechanisms such as callbacks and promises into a single, powerful construct. Learn to think about your programs as streams of data that you can transform by expressing what should happen, instead of having to painstakingly program how it should happen. You'll be able to handle real-world concurrency and write complex flows of events in your applications with ease.

Create highly concurrent applications while writing simpler code using the Reactive Extensions for JavaScript (RxJS), a set of libraries for event composition. Programming real-world applications in JavaScript involves lots of asynchronous events--you might end up spending more time coordinating asynchronous code in your program than writing its actual functionality. This book introduces concepts and tools from reactive programming that will help you write cleaner and more robust asynchronous programs.

Find out about Observable sequences, a unifying data type to write highly concurrent code. Discover Schedulers and change the concept of time in your applications, making asynchronous testing sane again. Along the way you'll see real-world examples for the browser and Node.js, including a real-time earthquake visualization in 20 lines of code and a frantic shoot-'em-up space videogame. You'll also use Cycle.js - a modern, fully reactive web framework - to make a whole new breed of web applications.

By the end of the book, you'll know how to apply reactive programming to solve complex problems, build efficient programs with reactive user interfaces, and write your code more declaratively.

This is an excellent introduction to RxJS. Written very clearly, it provides compelling reasons why you should consider reactive extensions (Rx) with great examples using RxJS to show why its useful. Unlike some other books, it tries to be short and to the point. If you just read the preface, and first two or three chapters you will be have a basic understanding of the point of RxJS - the rest is really just (important) sugar on top if decide to start really using it.

Read it a while ago, but still hold the opinion that this book is almost like a reference for Rx library.

Concise, accurate, examples are mostly real-life applications of RxJs and/or games that you can build on. This makes the book even more useful.

One of the greatest programming books I've ever read. Short, not complicated, everything to the point.

Well written introductory book to power of Rx with well formed examples in RxJs. Style is clean and clear, which helps a lot with getting through the presented material, good for getting started by providing the right practical purposes to illustrate the power of Reactive extensions.

Good one evening intro into RxJs. I'd like to see more advice on how to tame and till make sense of streams when they infest a larger application. If you new to rxjs and Observable pattern in general - do read the book. If you more on the advanced side - chapter on Schedulers could be interesting.
