Node.JS Not working on the internet

问题

This question was migrated from Software Engineering Stack Exchange because it can be answered on Stack Overflow. Migrated 8 years ago.

i have the basic webserver hello world app for nodejs on windows and it works on localhost. But when i test it from the internet it cannot connect. I set up port forwarding in my netgear router. Am i missing a step here to make my nodejs server visible to the outside world?

Thanks.

var http = require('http');
http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('Hello World\n');
}).listen(1337, "127.0.0.1");
console.log('Server running at http://127.0.0.1:1337/');

Make sure you listen on 0.0.0.0 instead of 127.0.0.1

127.0.0.1 is a private network visible only to your computer. 0.0.0.0listens to all interfaces, including both the private and public (as public as it can be behind a NAT).

Looks like you're binding the server to IP Address 127.0.0.1 which is localhost. If you want to access it elsewhere you'll need to set it to it's internet IP. Check out whatismyip.com and use that IP instead.
