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.

The Node community has embraced testing from the beginning, and many testing frameworks and native tools are made available to developers. In this chapter we've examined why testing is so important to modern software development, as well as something about functional, unit, and integration testing, what they are and how they can be used. With the vm module we learned how to create special contexts for testing JavaScript programs, along the way picking up some techniques for sandboxing untrusted code.

In addition we've learned how to work with the extensive set of Node testing and error-handling tools, from more expressive console logging to Move onto one line tracing and debugging. Through the assert and domain modules we were exposed to error catching and reporting mechanisms, giving us a more robust way to specifically target errors and exceptions, rather than simply catching all in one global handler.

Finally, we learned how to set up a proper build and test system using Grunt and...
