Answer 1

This the approach that worked for me.

var ObjectId = require('mongodb').ObjectID;

var get_by_id = function(id, callback) {
  console.log("find by: "+ id);
  get_collection(function(collection) {
    collection.findOne({"_id": new ObjectId(id)}, function(err, doc) {
       callback(doc);
    });
  });
}
