Node.js MongoDB Create a Database
When working with Node.js and MongoDB, creating a new database is a simple and straightforward process. You only need to connect your Node.js application to MongoDB using the MongoClient object. Once the connection is established, MongoDB will automatically create the database if it doesn’t already exist.

Steps to Create a Database in MongoDB Using Node.js
1. Create a Folder
Create a new folder on your desktop and name it MongoDatabase. This folder will contain your database creation script.
2. Create a JavaScript File
Inside the MongoDatabase folder, create a file named createdatabase.js and add the following code:

var MongoClient = require('mongodb').MongoClient;
var url = "mongodb://localhost:27017/MongoDatabase";
MongoClient.connect(url, function(err, db) {
if (err) throw err;
console.log("Database created!");
db.close();
});
Explanation:
- MongoClient is used to connect to the MongoDB server.
- The url variable defines the connection string, which includes the server location (localhost), port number (27017), and database name (MongoDatabase).
- When the connection is successful, MongoDB automatically creates the database if it doesn’t exist, and the message “Database created!” will be displayed in the console.

3. Run the Script
Open your command prompt or terminal, navigate to the MongoDatabase folder, and execute the following command:
node createdatabase.js
After running the command, you will see the message:
Database created!
This confirms that the connection was successful and the MongoDB database has been created.
