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.

In this chapter we've gone over three of the major strategies employed when building real-time applications: AJAX, WebSocket, and SSE. We've shown that non-trivial collaborative applications can be developed with very little code by using Node. We've also seen how some of these strategies enable the modeling of client/server communication as an evented data stream interface. We've considered the pros and cons of these various techniques, and we've gone through some clear examples of the best places to use each one.

Additionally, we've shown how client identifiers and state date can be built and managed within a Node server, such that state changes can be safely encapsulated in a central location and broadcasted out to many connected clients safely and predictably. Demonstrating the quality of the modules being developed with the Node community, we created a collaborative code editing system through the use of operational transformation.

In the next chapter we will be looking at how...
