How to return multiple Mongoose collections in one get request?

Question

I am trying to generate a response that returns the same collection sorted by 3 different columns. Here\'s the code I currently have:

var findRoute = router.

Crete an object to encapsulate the information and chain your find queries, like:

var findRoute = router.route("/find");
var json = {};

findRoute.get(function(req, res) {
  Box.find(function(err, boxes) {
    json.boxes = boxes;

    Collection2.find(function (error, coll2) {
      json.coll2 = coll2;

      Collection3.find(function (error, coll3) {
        json.coll3 = coll3;

        res.json(json);
      }).sort("-size");
    }).sort("-name");
  }).sort("-itemCount");
});

Just make sure to do the appropriate error checking.

This is kind of uggly and makes your code kind of difficult to read. Try to adapt this logic using modules like async or even promises (Q and bluebird are good examples).
