Description
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.
