  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 create

  reactive 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 RxJS

  AUDIENCE

  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.
