Create Collection

MongoDB is a NoSQL database so data is stored in collection instead of table. createCollection method is used to create a collection in MongoDB.

Example

Create a collection named "employees".

Create a js file named "employees.js", having the following data:

snippet
var MongoClient = require('mongodb').MongoClient;
var url = "mongodb://localhost:27017/ MongoDatabase";
MongoClient.connect(url, function(err, db) {
if (err) throw err;
db.createCollection("employees", function(err, res) {
if (err) throw err;
console.log("Collection is created!");
db.close();
});
});

Open the command terminal and run the following command:

snippet
Node employees.js
Node.js Create collection 1

Now the collection is created.
