Overview of this book

Node.js is a modern development stack focused on providing an easy way to build scalable network software. Backed by a growing number of large companies and a rapidly increasing developer base, Node is revolutionizing the way that software is being built today. Powered by Google's V8 engine and built out of C++ modules, this is a JavaScript environment for the enterprise.Mastering Node.js will take the reader deep into this exciting development environment. Beginning with a comprehensive breakdown of its innovative non-blocking evented design, Node's structure is explained in detail, laying out how its blazingly fast I/O performance simplifies the creation of fast servers, scalable architectures, and responsive web applications.Mastering Node.js takes you through a concise yet thorough tour of Node's innovative evented non-blocking design, showing you how to build professional applications with the help of detailed examples.Learn how to integrate your applications with Facebook and Twitter, Amazon and Google, creating social apps and programs reaching thousands of collaborators on the cloud. See how the Express and Path frameworks make the creation of professional web applications painless. Set up one, two, or an entire server cluster with just a few lines of code, ready to scale as soon as you're ready to launch. Move data seamlessly between databases and file systems, between clients, and across network protocols, using a beautifully designed, consistent, and predictable set of tools.Mastering Node.js contains all of the examples and explanations you'll need to build applications in a short amount of time and at a low cost, running on a scale and speed that would have been nearly impossible just a few years ago.

Introducing AJAX

In 2005, Jesse James Garrett published an article in which he tried to condense the changes he had been seeing in the way that websites were being designed into a pattern. After studying this trend, Garrett proposed that dynamically updating pages represented a new wave of software, resembling desktop software, and he coined the acronym "AJAX" to describe the technological concept powering such rapid movement toward "web applications".

This was the diagram he used to demonstrate the general pattern:

The "Ajax engine" Garrett's diagram referred to, had in fact existed in most common browsers by the year 2000, and even earlier in some. JavaScript implementations of the XMLHttpRequest (XHR) object in these browsers gave web pages the ability to request "chunks" of HTML or other data from servers. Partial updates could be dynamically applied to a web page, creating the...
