Summary

RxJS in Action gives you the development skills you need to create reactive applications with RxJS. This book is full of theory and practical examples that build on each other and help you begin thinking in a reactive manner. Foreword by Ben Lesh, Project lead, RxJS 5.

Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications.

About the Technology

On the web, events and messages flow constantly between UI and server components. With RxJS, you can filter, merge, and transform these streams directly, opening the world of data flow programming to browser-based apps. This JavaScript implementation of the ReactiveX spec is perfect for on-the-fly tasks like autocomplete. Its asynchronous communication model makes concurrency much, much easier.

About the Book

RxJS in Action is your guide to building a reactive web UI using RxJS. You'll begin with an intro to stream-based programming as you explore the power of RxJS through practical examples. With the core concepts in hand, you'll tackle production techniques like error handling, unit testing, and interacting with frameworks like React and Redux. And because RxJS builds on ideas from the world of functional programming, you'll even pick up some key FP concepts along the way.

What's Inside

• Building clean, declarative, fault-tolerant applications
• Transforming and composing streams
• Taming asynchronous processes
• Integrating streams with third-party libraries
• Covers RxJS 5

Summary

DESCRIPTION
A growing flood of data is aimed at JavaScript applications, and they
need be ready for it. As more and more data is received, applications
must scale to stay operational. There’s also the problem of latency
when data has to be fetched from remote locations. RxJS, or Reactive
Extensions for JavaScript, is a library for transforming, composing,
and consuming streams of data. RxJS combines reactive and functional
programming to give an extensible, asynchronous event handling
system for JavaScript.

RxJS in Action gives readers the development skills they need to createreactive applications with RxJS. This book is full of theory and
practical examples that build on each other and help readers begin
thinking in a reactive manner. The book begins by teaching the
fundamentals of functional programming, and dives in to the basics of
RxJS and what it means to be reactive. Next, it teaches how to build
real-world applications with RxJS. The last part of the book tackles the
advanced topics to take the reader’s reactive programming skills to the
next level, as they will learn how to deal with error handling, unit
testing, and the role of RxJS when combined with frameworks such as
Angular.js or Cycle.js. Examples in the book use RxJS 5, the latest
version of RxJS built with an eye on performance and simplicity.

KEY FEATURES• Full of practical examples using real-world applications
• Creating readable, easy-to-understand event processing pipelines
• Introduces the fundamentals of functional and reactive programming
• Transforms bulky, untestable code into modular, testable expressions
• Uses the latest version of RxJSAUDIENCE
This book is for readers who are comfortable writing and building
applications in JavaScript.
ABOUT THE TECHNOLOGY
RxJS combines reactive and functional programming to give programmers
an extensible, asynchronous event handling system for JavaScript. RxJS is
ideal for applications with features that have continuous data flows that have
to fetch and combine multiple pieces of remote data, auto-complete text
boxes, drag and drop, process user input, and more.
