Answer 1

I solved it by this:

npm install shelljs

and add code for kill nodejs process before start listen port

var shell = require('shelljs');
shell.exec("pkill nodejs");
shell.exec("pkill node");

/* Make the http server listen on port 3000. */
http.listen(3000, function(){
 console.log('listening on *:3000');
});
