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.

Building a collaborative document editing application


Now that we've examined various techniques to consider when building a collaborative application, let's put together a collaborative code editor using one of the most exciting contributions to Node to arrive in the last year: Operational transformation (OT).

For our discussion here, OT will be understood as a technology that allows many people to edit the same document concurrently—collaborative document editing. Google described their (now defunct) Wave project in the following way:

Collaborative document editing means multiple editors are able to edit a shared document at the same time. It is live and concurrent when a user can see the changes another person is making, keystroke by keystroke. Google Wave offers live concurrent editing of rich text documents.

One of the engineers involved in the Wave project was Joseph Gentle, and Mr. Gentle was kind enough to write a...
