I think you might find caolan/async useful. Look especially into async.waterfall. It will allow you to pass results from a callback from another and when done, do something with the results.

Example:

async.waterfall([
    function(cb) {
        request.get({
            url: 'aaa.com'
        }, function(err, res, body) {
            if(err) {
                return cb(err);
            }

            cb(null, JSON.parse(body).id);
        });
    },
    function(id, cb) {
        // do that otherFunc now
        // ...
        cb(); // remember to pass result here
    }
], function (err, result) {
   // do something with possible error and result now
});
