Create collection in MongoDB using node.js

In this part of the mongodb operations using node.js tutorial series , we will create a collection details in MongoDb using Node.js

We will start by including mongodb npm package as shown below :

												
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"
												
											

• demo_db is the name of the database. You can change it in accordance with your database name.
• 27017 is the port where mongoDb is running.
• Localhost i.e. 127.0.0.1 is the local IP.

createCollection() is an inbuilt method which is used to create a new collection in mongodb database as shown below:

											
//create-collection.js
var mongo = require('mongodb');
var new_db = "mongodb://localhost:27017/demo_db";

mongo.connect(new_db , (error , db) => {
	if (error){
		throw error;
	}
		
	//CREATING A COLLECTION IN MONGODB USING NODE.JS
	db.createCollection("details" , (err , collection) => {
		if(err) throw err;
		
		console.log("Details collection created successfully");
		
	});
});
											
										

											
>node create-collection.js
Details collection created successfully
