In Mongoose, how do I sort by date? (node.js)

Sorting in Mongoose has evolved over the releases such that some of these answers are no longer valid. As of the 4.1.x release of Mongoose, a descending sort on the date field can be done in any of the following ways:

    Room.find({}).sort('-date').exec((err, docs) => { ... });
    Room.find({}).sort({date: -1}).exec((err, docs) => { ... });
    Room.find({}).sort({date: 'desc'}).exec((err, docs) => { ... });
    Room.find({}).sort({date: 'descending'}).exec((err, docs) => { ... });
    Room.find({}).sort([['date', -1]]).exec((err, docs) => { ... });
    Room.find({}, null, {sort: '-date'}, (err, docs) => { ... });
    Room.find({}, null, {sort: {date: -1}}, (err, docs) => { ... });

For an ascending sort, omit the - prefix on the string version or use values of 1, asc, or ascending.

The correct answer is:

Blah.find({}).sort({date: -1}).execFind(function(err,docs){

});

Been dealing with this issue today using Mongoose 3.5(.2) and none of the answers quite helped me solve this issue. The following code snippet does the trick

Post.find().sort('-posted').find(function (err, posts) {
    // user posts array
});

You can send any standard parameters you need to find() (e.g. where clauses and return fields) but no callback. Without a callback it returns a Query object which you chain sort() on. You need to call find() again (with or without more parameters -- shouldn't need any for efficiency reasons) which will allow you to get the result set in your callback.

Post.find().sort({date:-1}, function(err, posts){
});

Should work as well

EDIT:

You can also try using this if you get the error sort() only takes 1 Argument :

Post.find({}, {
    '_id': 0,    // select keys to return here
}, {sort: '-date'}, function(err, posts) {
    // use it here
});

I do this:

Data.find( { $query: { user: req.user }, $orderby: { dateAdded: -1 } } function ( results ) {
    ...
})

This will show the most recent things first.

All the anwsers here are factually correct, however I am writing my anwser to make it clear that sometimes writing '-date' or date: -1 won't work if you either don't have a field named 'date' in your model, or if you passed the option: timestamps: true in options when creating your model. If you are using timestamps: true then you need to type: sort({createdAt: -1}) and this will work then.

Short solution:

const query = {}
const projection = {}
const options = { sort: { id: 1 }, limit: 2, skip: 10 }

Room.find(query, projection, options).exec(function(err, docs) { ... });

This one works for me.

`Post.find().sort({postedon: -1}).find(function (err, sortedposts){
    if (err) 
        return res.status(500).send({ message: "No Posts." });
    res.status(200).send({sortedposts : sortedposts});
 });`

ES6 solution with Koa.

  async recent() {
    data = await ReadSchema.find({}, { sort: 'created_at' });
    ctx.body = data;
  }

You can also sort by the _id field. For example, to get the most recent record, you can do,

const mostRecentRecord = await db.collection.findOne().sort({ _id: -1 });

It's much quicker too, because I'm more than willing to bet that your date field is not indexed.
