NodeJS - Error: listen EADDRNOTAVAIL: address not available

Question

I am running a Node app that should be hosted on a local server. At the moment, I am sending just a plaintext response.

const http = require('http');

var server = http.createServer(function(req, res) {
  res.writeHead(200, {ContentType: 'text/plain'});
  res.end("test");
});

When I listen to the localhost everything works fine and I am able to send the request from my browser.

server.listen(3000, '127.0.0.1'); // works fine, on the same machine

However, if I try to listen to a port on my LAN network by typing the router's IP, I get an error.

server.listen(3000, '192.168.0.1'); // causes an error

Error: listen EADDRNOTAVAIL: address not available 192.168.0.1:3

I have tried this with my public IP address unsuccessfully. Is there any way to listen to a port on a LAN server so that I can send requests from any computer on the network?
Also, I would later like my application to run on any computer on any LAN network. How can I dynamically add my host?

Answer 1

Try this

server.listen(3000, '0.0.0.0');

you can access your node application from other machine

e.g

your lan ip is 192.168.0.101 then you can browse 192.168.0.101:3000 from other machine

Answer 2
