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: 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();
});
});
