How to sort a collection by date in MongoDB?

db.getCollection('').find({}).sort({_id:-1}) 

This will sort your collection in descending order based on the date of insertion

Just a slight modification to @JohnnyHK answer

collection.find().sort({datefield: -1}, function(err, cursor){...});

In many use cases we wish to have latest records to be returned (like for latest updates / inserts).
