api like this:

function map(doc) {
  // sort by last name, first name, and age
  emit([doc.lastName, doc.firstName, doc.age]);
}
db.query(map).then(function (result) {
  // handle result
}).catch(function (err) {
  console.log(err);
});

but i want to sort data desc or asc

use sql like this:

select * from table order by lastName desc

When you query, you can do descending: true or descending: false. There' s a blog post on it here: https://pouchdb.com/2014/04/14/pagination-strategies-with-pouchdb.html

And a guide here: https://pouchdb.com/guides/queries.html
