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 3. Streaming Data Across Nodes and Clients


A jug fills drop by drop.


We now have a clearer picture of how the evented, I/O-focused design ethic of Node is reflected across its various module APIs, delivering a consistent and predictable environment for development. In this chapter we will discover how data, of many shapes and sizes, pulled from files or other sources, can be read, written, and manipulated just as easily using Node. Ultimately we will learn how to use Node to develop networked servers with rapid I/O interfaces that support highly concurrent applications sharing real-time data across thousands of clients simultaneously.

Those who work with Internet-based software will have heard about "Big Data". The importance of I/O efficiency is not lost on those witnessing this explosive growth in data volume.

Implied by this expansion in data is an increase in the size of individual media objects transmitted over the network. The videos being watched are longer. The images...
