Package Exports
- mdns-js
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (mdns-js) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
mDNS-js
Pure JavaScript/NodeJS mDNS discovery implementation.
A lot of the functionality is copied from https://github.com/GoogleChrome/chrome-app-samples/tree/master/mdns-browser but adapted for node.
Install by
npm install mdns-jsFuture
It would be great to have a full implementation of mDSN + DNS-SD in pure JS but progress will be slow unless someone is willing to pitch in with pull requests, specifications for wanted functions etc. Also, as you should avoid to have multiple mDNS stacks on a system this might clash with stuff like avahi and bonjour.
example
var Mdns = require('mdns-js');
var mdns = new Mdns();
mdns.on('ready', function () {
mdns.discover();
});
mdns.on('update', function () {
console.log('ips with _workstation._tcp service', mdns.ips('_workstation._tcp'));
console.log('services on host 10.100.0.61', mdns.services('10.100.0.61'));
});Debugging
This library is using the debug module from TJ Holowaychuk and can be used like this.
DEBUG=mdns* node examples/simple.jsThis will spit out a lot of information that might be useful.
