The example that really made sense for me was from "Smooth Coffeescript" in which the author writes an entire nodejs app in one file. Here, I'll show you: http://autotelicum.github.com/Smooth-CoffeeScript/ http://autotelicum.github.com/Smooth-CoffeeScript/ webpage = kup.render -> doctype 5 html -> head -> meta charset: 'utf-8' title 'My drawing | My awesome website' style ''' body {font-family: sans-serif} header , nav, section , footer {display: block} ''' coffeescript -> draw = (ctx, x, y) -> circle = (ctx, x, y) -> ctx.beginPath() ctx.arc x, y, 100, 0, 2*Math.PI, false ctx.stroke() ctx.strokeStyle = 'rgba(255,40,20,0.7)' circle ctx, x, y for angle in [0...2*Math.PI] by 1/3*Math.PI circle ctx, x+100*Math.cos(angle), y+100*Math.sin(angle) window.onload = -> canvas = document.getElementById 'drawCanvas' context = canvas.getContext '2d' draw context , 300, 200 body -> header -> h1 'Seed of Life' canvas id: 'drawCanvas', width: 600, height: 400 http = require 'http' server = http.createServer (req, res) -> show "#{req.client.remoteAddress} #{req.method} #{req.url}" res.writeHead 200, 'Content -Type': 'text/html' res.write webpage res.end() server.listen 3389 show 'Server running at' show server.address() Notice something missing? - There's no separate file for the HTML template - There's no separate file for the javascript inside - There's no separate file for the web server It's just "node circles.coffee" and you're good to go. CoffeeKup makes this sort of one-shot webapp experiment scripts particularly easy. Now you don't need an entire folder for each of your sandbox projects.
