A module to query SRV records from DNS servers

Usage: To query the _xmpp-client._tcp SRV record of gmail.com.

var srv = require('dns-srv');
var net = require('net');

var sock = new net.Stream();
srv.connect(sock // This socket will become connected if everything goes well
         , ['_xmpp-client._tcp'] // The SRV record to query
         , "gmail.com" // The domain whose DNS SRV we are interested in
         , 5222 // Default fallback port to connect to in case SRV lookup failed
);

sock.on('error', function() { console.error('meh...'); })
    .on('connect', function() { console.log('yeah baby!!'); });
