Node Cookbook

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.

Generating Express scaffolding

Express works both as a Node module and as a command-line executable. When we run express from the command line it generates a project skeleton for us, accelerating the preparation process.

Getting ready

We need to install express using the -g flag (install globally) in order to run the express executable from any directory.

sudo npm -g install express

We use sudo to ensure we get permission to install globally. This doesn't apply under Windows.

How to do it...

First, we decide upon the name of our app. Let's call it nca (Node Cookbook App) and simply do:

express nca

This will generate all of our project files under a new directory called nca. Before we can run our app, we must ensure that all dependencies are installed. We can find app dependencies in nca/package.json:

"name": "application-name"
, "version": "0.0.1"
, "private": true
, "dependencies": {
"express": "2.5.8"
, "jade": ">= 0.0.1"

For portability, it's important to have relevant modules...
