Error first callback for listening on the server.
This module is born out of an annoyance with the Node core. Every method that
receives a callback is called using an error first callback. But this is not the
case with servers. When you tell the server to start listening on the given port
it can will
error event when it failed.
npm install connected --save
var connected = require'connected'http = require'http';var app = httpcreateServerresend'wobble wobble';;connectedapp 80// Received an error because we are not allowed to listen on port 80;
And thats it.
