⚠️ This is a Major update Since version 3.0.0 this package is using a Typescript Implementation and it is fully tested on Mac OS 13.2 and windows 11 and ubuntu If you have any issue feel free to open an issue here

Advanced mDNS Listener to add and listen .local hostnames in your network compatible with zeroconf, bonjour, avahi

I recommand using python publisher https://github.com/aminekun90/python_zeroconf_publisher since this code is fully compatible with it, if you dont have access to it you can contact me further bellow 😉 I can make you an offer.

Note: The original idea was from @Richie765 https://github.com/Richie765/mdns-listener and got updated and enhanced, few parts of the original code still exist, recently updated to typescript.

npm install mdns-listener-advanced

Fully tested on windows 11, ubuntu 18 and Mac OS 13.

var mdnsListenerAdvanced = require("mdns-listener-advanced");
const mdns = new mdnsListenerAdvanced.Core(['MyDevice2']);
const event = mdns.listen();
event.on('response', (found_hostnames) => {
  console.log('found_hostnames', found_hostnames);
  // mdns.stop();// To stop the listener
});
event.on('error', (error) => {
  console.log('error', error);
  // mdns.stop();// To stop the listener
});

✅ Fully tested

import { Core } from "mdns-listener-advanced";
const mdns = new Core(['MyDevice2']);
const event = mdns.listen();
event.on('response', (found_hostnames) => {
  console.log('found_hostnames', found_hostnames);
  // mdns.stop();// To stop the listener
});
event.on('error', (error) => {
  console.log('error', error);
  // mdns.stop();// To stop the listener
});

• To Stop listening to the event use :

mdns.stop();

Provide hostnames list in the constructor like this :

var mdnsListenerAdvanced = require("mdns-listener-advanced");
const mdns = new mdnsListenerAdvanced.Core(['MyDevice1','MyDevice2']);

The file .mdns-hosts is created automatically.

Add and Edit the file named .mdns-hosts, this file must be in your HOME directory for windows [HDD]:\Users\<username>\.mdns-hosts and for linux/Mac ~/.mdns-hosts, place hostnames ending on separate lines like so:

myhost1
myhost2

You can specify the hostnames that you want to detect !

Whenever you change this file, you should restart the service.
