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.

Chapter 7. Utilizing Multiple Processes


"It is a very sad thing that nowadays there is so little useless information."

 --Oscar Wilde

The importance of I/O efficiency is not lost on those witnessing the rapidly increasing volume of data being produced within a growing number of applications. User-generated content (blogs, videos, tweets, posts) is becoming the premier type of internet content, and this trend has moved in tandem with the rise of social software, where mapping the intersections between content generates an exponential rise in yet another level of data.

A number of data silos, such as Google, Facebook, and hundreds of others, expose their data to the public through an API, often for free. These networks each gather astounding volumes of content, opinions, relationships, and so forth from their users, data further augmented by market research and various types of traffic and usage analysis. Most of these APIs are two-way, gathering and storing data uploaded by their members as...
