In this part of the mongodb operations using node.js tutorial series , we will create a database
demo_db
in MongoDb
using Node.js
We will start by installing mongodb
package
from the node package manager npm
as shown below
npm install mongodb --save
var mongo = require('mongodb');
Establish a connection between the mongoDb database and our node.js app using the following :
var new_db = "mongodb://localhost:27017/demo_db"
Connect()
is an inbuilt method used to create connection to a mongodb
instance and returns the reference to the database. It instantiates a new connection to the mongodb
instance running on the localhost
interface and returns a reference to demo_db
:
//create-db.js
var mongo = require('mongodb');
var new_db = "mongodb://localhost:27017/demo_db";
mongo.connect(new_db ,(error , db) => {
if (error){
throw error;
}
console.log("Database demo_db created successfully");
//To close the connection
db.close();
});
>node create-db.js
Database demo_db created successfully
In this article we learned about

package from npm.
