var ws = new WebSocketServer({port: 8080, path: "OptionalPathName"});A Simple WebSocket Server Example
var WebSocketServer = require('ws').Server
, wss = new WebSocketServer({ port: 8080 }); // If you want to add a path as well, use path:
"PathName"
wss.on('connection', function connection(ws) {
ws.on('message', function incoming(message) {
console.log('received: %s', message);
});
ws.send('something');
});
