javascript - Attach to a Socket.io server instance in a background task -

i using socket.io in conjunction express in web application this:

var server = express(); var http = require('http').server(server); io = require('socket.io')(http); ... server.set('port', process.env.port || 3000);  http.listen(server.get('port'), function() {     console.log('listening on port ' + server.get('port')); });
