Integrate NowJS with Express and Passport

gistfile1.js

var express = require('express')
  , passport = require('passport')
  , sessionStore = new express.session.MemoryStore()

  , app = module.exports = express.createServer()

  , nowjs = require('now');

app.configure( function () {
	app.use(express.bodyParser());
	app.use(express.methodOverride());
	app.use(express.cookieParser('connect'));
	app.use(express.session({ secret : "connect", store : sessionStore }));
	
	app.use(passport.initialize());
  	app.use(passport.session());

	app.use(express.errorHandler({dumpExeptions: true, showStack : true}));

	app.use(app.router);
});

nowjs.on('connect', function() {
        var self = this;

        if ( this.user.cookie && this.user.cookie['connect.sid'] ) {
		var sid = decodeURIComponent( this.user.cookie['connect.sid'] );	
		sessionStore.get( sid, function( err, session ) {
		    if ( session ) {
			passport.deserializeUser(session.passport.user, function(err, user) {
			     self.user.session.passport = user;
			});
                    }
    		});
	};
});

var everyone = nowjs.initialize(app);
app.listen(3000);
console.log('app is listening');

everyone.now.getUsername( function (cb) {
    if ( this.user.session && this.user.session.passport && this.user.session.username ) cb(this.user.session.username);
});

Of course you should have written your passport Strategy file and authentication mechanism.
