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:
- Node createdatabase.js
