[nodejs] mDNS/zeroconf/bonjour service discovery add-on

[David Siegel]

Hi everyone.
I'm absolutely new to node.js. Nevertheless, last weekend i somehow
found myself hacking on a mDNS add-on. Although it is quite
unfinished, lacking error handling, tests and documentation it already
does something (useful). To advertise a service do:

var mDNS = require('./mDNS');
var ad = mDNS.createAdvertisement('http', 4321, mDNS.TCP);
ad.start();

To browse for a service do:

var browser = mDNS.createBrowser('http', mDNS.TCP);
browser.addListener('serviceUp', function(info) { p('found', info); });
browser.addListener('serviceDown', function(info) { p('gone', info); });
browser.start();

The source code is available here:

http://github.com/agnat/node_mDNS

Comments, suggestions and patches are more than welcome.

Cheers,
David

Hey, that's really cool.  Thanks for making that.

Awesome, get this production quality and it will be super useful!

HI - trying to run this (super-useful), but getting an error when
I start my node.js server.

I'm including:

var mdns = require('../agnat/node_mdns/lib/mdns');

the error is below - stats that the load cannot find the 'binding.js' file.
I have none. As well, your README.textile file states:

node-waf configure build && ./run_tests

I only see a 'run_tests' script, no configure or build.

Thanks.
