mongoose: find most recent document

Question

I have mongoose schema which has a day attribute which is just

Math.floor((new Date()).getTime() / (24 * 3600 * 1000))

and I want to find

Answer 1

In the shell it would be:

db.test.find({day: {$lt: 16085}}).sort({day: -1}).limit(1)

Which finds all the docs where day is less than 16085, sorts them on day descending, and then takes the first one.

In Mongoose it would be something like:

MyModel.find({day: {$lt: 16085}}).sort({day: -1}).limit(1).exec((err, docs) => { ... });
