Node.js MongoDB Create Database

To create a database in MongoDB, First create a MongoClient object and specify a connection URL with the correct ip address and the name of the database which you want to create.

Note: MongoDB will automatically create the database if it does not exist, and make a connection to it.

Example

Create a folder named “MongoDatabase” as a database. Suppose you create it on Desktop. Create a js file named “createdatabase.js” within that folder and having 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();  

});

Now open the command terminal and set the path where MongoDatabase exists. Now execute the following command:PlayNextMute
