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.

Routing requests

HTTP is a data transfer protocol built upon a request/response model. Using this protocol many of us communicate our current status to friends, buy presents for family, or discuss a project over e-mail with colleagues. A staggering number of people have come to depend on this foundational Internet protocol.

Typically, a browser client will issue an HTTP GET request to a server. This server then returning the requested resource, often represented as an HTML document. HTTP is stateless, which simply means that each request or response maintains no information on previous requests or responses—with each back and forward movement through web pages the entire browser state is destroyed and rebuilt from scratch.

Servers route state change requests from clients, ultimately causing new state representations to be returned, which clients (often browsers) redraw or report. When the WWW was first conceived this model made sense. For the most part this new network was understood as a...
