Tokyo NodeFest 2011　(translated by jedschmidt from the original)

I'm a little late to write this, but I presented at and helped run Tokyo NodeFest 2011 on 10/29.

Tokyo NodeFest 2011

My presentation was aimed at beginners, using live-coding to explain how to use Express and Socket.IO to build a simple application. I worked a little bit on the slides, but they paled in comparison to Guillermo "wizard-level hacker" Rauch's awesome session, making me keenly aware of how great these things can be.

The slides I used are below. The HTML I used had a demo embedded, as you can read later. I also uploaded them to SlideShare.

experimenting with a more general way of hashing a namespace, for future javascript golf. the idea is that existing browser objects can be hashed so that wasteful strings like createDocumentFragment can be avoided entirely, and keys from several objects (such as document, window, String, etc.) can be hashed into one namespace.

for example:

d = document
d.body.appendChild(d.createElement("script")).src="URL"

could be shortened to

	// usage: newOperator(constructor, [arg1, arg2, ...])
	// example: newOperator(Date, [1995, 11, 24])
	// => should be identical to new Date(1995, 11, 24)

	function newOperator(constructor, args) {
	var i = args.length + 1
	, params = []
	, fn

	while (i--) params[i] = "$" + i

	HTML lang: en,
	HEAD {},
	TITLE "Hello, world."
	META charset: "utf8"

	BODY {},
	DIV id: "container"
	"Welcome to my website."

	// Usage:
	// function asyncAdd(a, b, cb){ cb(a + b ) }
	//
	// var syncAdd = sync(asyncAdd)
	// , sum = syncAdd(2, 2)
	//
	// assert(sum == 4)
	//
	// NOTE:
	// this only works for functions that execute their callback before returning.

	var url = require("url")
	, https = require("https")

	exports.Application = function(options) {
	if (!options.secret) throw "No application secret provided."
	if (!options.clientId) throw "No application client ID provided."

	return function(req, res) {
	var protocol = res.socket.encrypted ? "https" : "http"
	, uri = protocol + "://" + req.headers.host + req.url
