It used to work with the older versions of MongoDb client ~ 2.2.33
Option 1: So you can either use the older version
npm uninstall mongodb --save
npm install [email protected] --save
Option 2: Keep using the newer version (3.0 and above) and modify the code a little bit.
let MongoClient = require('mongodb').MongoClient;
MongoClient.connect('mongodb://localhost:27017', function(err, client){
if(err) throw err;
let db = client.db('myTestingDb');
db.collection('customers').find().toArray(function(err, result){
if(err) throw err;
console.log(result);
client.close();
});
});
