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.

Possible solutions

Add a submodule

git submodule add https://github.com/janjarfalk/canvasrunner.git components/canvasrunner/

Update all submodules

git submodule foreach git pull origin master
cd ..
git commit . -m "Updated submodules"

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

Setting up a local DNS server with bind on OSX Mavericks

This is really just an approach for locally testing DNS changes, which can easily be done with a HOSTS file if the change involves an IP address, but gets a bit trickier when things like CNAMEs are involved. This is only meant to test locally off a single machine.

Install bind using homebrew

brew install bind
Follow the installation steps to start up bind
