Last active March 12, 2016 20:33 — forked from webdesserts/Gulpfile.js

Adapt the gulp hot reload file and apply to partial.js directory structure. (ignored public folder at the moment)

	// NOTE: I previously suggested doing this through Grunt, but had plenty of problems with
	// my set up. Grunt did some weird things with scope, and I ended up using nodemon. This
	// setup is now using Gulp. It works exactly how I expect it to and is WAY more concise.
	var gulp = require('gulp'),
	spawn = require('child_process').spawn,
	node;

	/**
	* $ gulp server
	* description: launch the server. If there's a server already running, kill it.
