Virtual Hosts on nginx (CSC309)

When hosting our web applications, we often have one public IP address (i.e., an IP address visible to the outside world) using which we want to host multiple web apps. For example, one may wants to host three different web apps respectively for example1.com, example2.com, and example1.com/images on the same machine using a single IP address.

How can we do that? Well, the good news is Internet browsers

A quick overview of the node.js streams interface with basic examples.

Overview

Streams are a first-class construct in Node.js for handling data.

Think of them as as lazy evaluation applied to data.

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.

	#!/usr/bin/env node

	'use strict';

	var spawn = require('child_process').spawn;

	// Then use the JS Date function and its "parse" method to get a number (of milliseconds) to be able to compare dates.

	startBookDateObj = Date.parse( parseDate(startBookDate) );
	endBookDateObj = Date.parse( parseDate(endBookDate) );
