Node.js MongoDB Sort


Sort the Result

Use the sort() method to sort the result in ascending or descending order.

The sort() method takes one parameter, an object defining the sorting order.

Example

Sort the result alphabetically by name:

var MongoClient = require('mongodb').MongoClient;
var url = "mongodb://localhost:27017/";

MongoClient.connect(url, function(err, db) {
  if (err) throw err;
  var dbo = db.db("mydb");
  var mysort = { name: 1 };
  dbo.collection("customers").find().sort(mysort).toArray(function(err, result) {
    if (err) throw err;
    console.log(result);
    db.close();
  });
});
Run example »

Save the code above in a file called "demo_sort.js" and run the file:

Run "demo_sort.js"

C:\Users\Your Name>node demo_sort.js

Which will give you this result:

[
  { _id: 58fdbf5c0ef8a50b4cdd9a86, name: 'Amy', address: 'Apple st 652'},
  { _id: 58fdbf5c0ef8a50b4cdd9a8e, name: 'Ben', address: 'Park Lane 38'},
  { _id: 58fdbf5c0ef8a50b4cdd9a8a, name: 'Betty', address: 'Green Grass 1'},
  { _id: 58fdbf5c0ef8a50b4cdd9a90, name: 'Chuck', address: 'Main Road 989'},
  { _id: 58fdbf5c0ef8a50b4cdd9a87, name: 'Hannah', address: 'Mountain 21'},
  { _id: 58fdbf5c0ef8a50b4cdd9a84, name: 'John', address: 'Highway 71'},
  { _id: 58fdbf5c0ef8a50b4cdd9a88, name: 'Michael', address: 'Valley 345'},
  { _id: 58fdbf5c0ef8a50b4cdd9a85, name: 'Peter', address: 'Lowstreet 4'},
  { _id: 58fdbf5c0ef8a50b4cdd9a8b, name: 'Richard', address: 'Sky st 331'},
  { _id: 58fdbf5c0ef8a50b4cdd9a89, name: 'Sandy', address: 'Ocean blvd 2'},
  { _id: 58fdbf5c0ef8a50b4cdd9a8c, name: 'Susan', address: 'One way 98'},
  { _id: 58fdbf5c0ef8a50b4cdd9a8d, name: 'Vicky', address: 'Yellow Garden 2'},
  { _id: 58fdbf5c0ef8a50b4cdd9a91, name: 'Viola', address: 'Sideway 1633'},
  { _id: 58fdbf5c0ef8a50b4cdd9a8f, name: 'William', address: 'Central st 954'}
]


Sort Descending

Use the value -1 in the sort object to sort descending.

{ name: 1 } // ascending
{ name: -1 } // descending

Example

Sort the result reverse alphabetically by name:

var MongoClient = require('mongodb').MongoClient;
var url = "mongodb://localhost:27017/";

MongoClient.connect(url, function(err, db) {
  if (err) throw err;
  var dbo = db.db("mydb");
  var mysort = { name: -1 };
  dbo.collection("customers").find().sort(mysort).toArray(function(err, result) {
    if (err) throw err;
    console.log(result);
    db.close();
  });
});
