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.

Creating an HTTP server

HTTP is a stateless data transfer protocol built upon a request/response model: clients make requests to servers, which then return a response. Facilitating this sort of rapid patter network communication is the sort of I/O Node is designed to excel at, it has unsurprisingly become identified as primarily a toolkit for creating servers—though it can certainly be used to do much, much more. Throughout this book we will be creating many implementations of HTTP servers, as well as other protocol servers, and will be discussing best practices in more depth, contextualized within specific business cases. It is expected that you have already had some experience doing the same. For both of these reasons we will quickly move through a general overview into some more specialized uses.

At its simplest, an HTTP server responds to connection attempts, and manages data as it arrives and as it is sent along. A Node server is typically created using the createServer method of the...
