Accepted Answer

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).

Sorting by date doesn't require anything special. Just sort by the desired date field of the collection.

Updated for the 1.4.28 node.js native driver, you can sort ascending on datefield using any of the following ways:

collection.find().sort({datefield: 1}).toArray(function(err, docs) {...});
collection.find().sort('datefield', 1).toArray(function(err, docs) {...});
collection.find().sort([['datefield', 1]]).toArray(function(err, docs) {...});
collection.find({}, {sort: {datefield: 1}}).toArray(function(err, docs) {...});
collection.find({}, {sort: [['datefield', 1]]}).toArray(function(err, docs) {...});

'asc' or 'ascending' can also be used in place of the 1.

To sort descending, use 'desc', 'descending', or -1 in place of the 1.
