Overview of this book

The principles of asynchronous event-driven programming are perfect for today's web, where efficient real-time applications and scalability are at the forefront. Server-side JavaScript has been here since the 90's but Node got it right. With a thriving community and interest from Internet giants, it could be the PHP of tomorrow. "Node Cookbook" shows you how to transfer your JavaScript skills to server side programming. With simple examples and supporting code, "Node Cookbook" talks you through various server side scenarios often saving you time, effort, and trouble by demonstrating best practices and showing you how to avoid security faux pas. Beginning with making your own web server, the practical recipes in this cookbook are designed to smoothly progress you to making full web applications, command line applications, and Node modules. Node Cookbook takes you through interfacing with various database backends such as MySQL, MongoDB and Redis, working with web sockets, and interfacing with network protocols, such as SMTP. Additionally, there are recipes on correctly performing heavy computations, security implementations, writing, your own Node modules and different ways to take your apps live.

Preface

Implementing a virtual hosting paradigm


If we wish to host multiple sites on one server, we can do so with virtual hosting. Virtual hosting is a way to uniquely handle multiple domain names according to their name. The technique is surprisingly simple: we just look at the incoming Host header and respond accordingly. In this task, we're going to implement simple name based virtual hosting for static sites.

Getting ready

We'll create a folder called sites, with localhost-site and nodecookbook as subdirectories. In localhost-site/index.html we'll write the following:

<b> This is localhost </b>

And in nodecookbook/index.html we'll add the following code:

<h1>Welcome to the Node Cookbook Site!</h1>

For local testing, we'll want to configure our system with some extra host names so we can point different domains to our server. To do this, we edit /etc/hosts on Linux and Max OS X, or %SystemRoot%\system32\drivers\etc\hosts for Windows systems.
