I had a need to connect to websocket via php, send data and immediately disconnect. No need to wait for a response from the socket. I used elefant.io but after updating the libr
var socket = require( 'socket.io' );
var express = require( 'express' );
var http = require( 'http' );
var app = express();
var server = http.createServer( app );
var io = socket.listen( server );
io.sockets.on( 'connection', function( client ) {
console.log( "New client !" );
