How to execute sort and limit query together with mongoose?

Question

I have a method written with node as follows to query from the collection

  query: function (model, conditon, options) {
            console.log(conditon, options);
            return new Promise(function (resolve, reject) {
                options = options || {};

                model.find(conditon, {}, options).exec(function (error, data) {
                    if (error)
                        reject(error);
                    resolve(data);
                })
            })
        }

i want to fetch the data for the following query,

db.getCollection('_event').find({}).sort({'metadata.popularity': 1}).limit(10)

How should i modify the above method to support this query?

This is how i call the query function from another file,

 dbService.query(eventModel, { 'eventId': idRetrieved }, {});
 }).then(data => dbService.disconnectDb(data))
    .then(data => callback(data))
     .catch((error) => {
          dbService.disconnectDb(error).then(error => {
          console.log(error);
          callback({}, error);
})

Just call sort and limit on the Query object returned from the find call.

But you don't need to create your own Promise as exec already returns a promise if you don't provide a callback.

function (model, condition, options, sort, limit) {
    return model.find(condition, {}, options).sort(sort).limit(limit).exec();
}
