Grunt workflow for sass & coffee

Here's my workflow for Grunt for a simple frontend. Can be used with WordPress.

Package.json

{
    "name" : "random-website",
    "version" : "1.0.0",
    "devDependencies" : {
        "grunt" :                       "latest",
        "grunt-contrib-cssmin":         "*",
        "grunt-contrib-sass":           "*",
        "grunt-contrib-uglify":         "*",
        "grunt-contrib-imagemin":       "*",
        "grunt-contrib-watch":          "*",

    }
}

Gruntfile.js

'use strict';

module.exports = function(grunt) {

    // load all grunt tasks
