dns Then

Thin wrapper arround Node's dns module that makes the async functions promise aware. The wrapped methods return a promise the represents the value of the async operation. Traditional callbacks still work, allowing for a transparent drop-in for dns. Sync methods, classes and other helpers are not modified.

Example

Traditional Async

var dns = require('dns-then');
dns.lookup('cujojs.com', function (err, address) {
   ...
});

With Promises

var dns = require('dns-then');
dns.lookup('cujojs.com').then(...);
