“`javascript
const MongoClient = require(‘mongodb’).MongoClient;
// Connection URL
const url = ‘mongodb://localhost:27017’;
// Database name
const dbName = ‘myDatabase’;
// Create a new MongoClient
const client = new MongoClient(url, { useNewUrlParser: true, useUnifiedTopology: true });
// Connect to the server
client.connect(function (err) {
if (err) {
console.error(‘Error connecting to MongoDB:’, err);
return;
}
console.log(‘Connected successfully to localhost MongoDB server’);
// Use the specified database
const db = client.db(dbName);
// Perform operations on your database…
// Close the connection
client.close();
});
“`
Replace `myDatabase` with the name of the database you want to connect to or create.
8. Run your client application: In your terminal, run `node index.js` (or the name of your JavaScript file) to execute the script and establish a connection to your localhost MongoDB server.
After completing these steps, you will have successfully created a MongoDB connection to localhost.
