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.

Creating child processes

Software development is no longer the realm of monolithic programs. Applications running on networks cannot forego interoperability. Modern applications are distributed and decoupled. We now build applications that connect users with resources distributed across the Internet. Many users are accessing shared resources simultaneously. A complex system is easier to understand if the whole is understood as a collection of interfaces to programs that solve one or a few clearly defined, related problems. In such a system it is expected (and desirable) that processes do not sit idle.

An early criticism of Node was that it did not have multicore awareness. That is, if a Node server were running on a machine with several cores, it would not be able to take advantage of this extra horsepower. Within this seemingly reasonable criticism hid an unjustified bias based on a straw man: a program that is unable to explicitly allocate memory and execution "threads" in order to implement...
