MongoDB, the most popular NoSQL database, is an open-source document-oriented database. The term ‘NoSQL’ means ‘non-relational’. It means that MongoDB isn’t based on the table-like relational database structure but provides an altogether different mechanism for storage and retrieval of data. This format of storage is called BSON ( similar to JSON format).

MongoDB Module: This module of Node.js is used for connecting the MongoDB database as well as used for manipulating the collections and databases in MongoDB. The mongodb.connect() method is used for connecting the MongoDB database which is running on a particular server on your machine. (Refer to this article). 

Installing module:

npm install mongodb
    Project Structure:

  1. Create a new folder, let’s name it ‘NODE-MONGO’.
    mkdir NODE-MONGO
  2. Move to this directory.
  3. Let’s create a new NPM package for our project.
    npm init

Running the server on Local IP: data is the directory where MongoDB server is present.

Output of ‘show databases’



const MongoClient = require("mongodb"); 
const databasename = "GFG";// database name 
MongoClient.connect(url).then((client) => { 
    //use admin request
    const connect = client.db(databasename).admin(); 
    if(!err) {
            var arr=[]; //creating an empty array  
            db.databases.forEach(element => {
                arr.push( //push the name in the array
            arr.sort() //sort the array
            console.log(arr); //printing the array
.catch((err) => { 
    // Printing the error if there's any 

Run index.js file using below command:

node index.js

Console Output: (Sorted databases according to the ASCII values)
