Mastering Node.js

By: Sandro Pasquali

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.

Running multiple Node servers

It is easy to purchase several servers and then to run some Node processes on them. But how can those distinct servers be coordinated such that they form part of a single application? One aspect of this problem concerns clustering multiple identical servers around a single entry point. How can client connections be shared across a pool of servers?

Forward and reverse proxies

A proxy is someone or something acting on behalf of another.

A forward proxy normally works on behalf of clients in a private network, brokering requests to an outside network, such as retrieving data from the Internet. Earlier in this book we looked at how one might set up a proxy server using Node, where the Node server functioned as an intermediary, forwarding requests from clients to other network servers, usually via the Internet. Early web providers such as AOL functioned in the following way:

Network administrators use forward proxies when they must restrict access to the outside world...
