I am currently working mongodb and nodejs from w3schools website. I have seen an error in a code.
https://www.w3schools.com/nodejs/nodejs_mongodb_create_db.asp
In this website there is a code for creating website. :
var MongoClient = require('mongodb').MongoClient;
var url = "mongodb://localhost:27017/mydb";
MongoClient.connect(url, function(err, db) {
if (err) throw err;
console.log("Database created!");
db.close();
});
When I run this, I see this on the terminal:
(node:26812) DeprecationWarning: current Server Discovery and Monitoring engine is deprecated, and will be removed in a future version. To use the new Server Discover and Monitoring engine, pass option { useUnifiedTopology: true } to the MongoClient constructor.
Database created!
I needed to change 3rd line.
old 3rd line:
MongoClient.connect(url, function(err, db) {
new 3rd line:
MongoClient.connect(url, {useUnifiedTopology: true}, function(err, db) {
