You can use Mongoose library to connect to MongoDB in Node JS

 var mongoose = require('mongoose');
 mongoose.connect('mongodb://localhost:27017/'+db_to_connect,{ useNewUrlParser: true });

 var db = mongoose.connection;
 db.on('error', function(){             
 });
 db.once('open', ()=> {
 });

index.js

At first, install MongoDB module by running this command.

npm install mongodb --save

Just keep in mind that you can not create the only database. You have to create also the collection to see your new database.

const mongodb = require('mongodb');
const uri = 'mongodb://localhost:27017';
const client = new mongodb.MongoClient(uri);

client.connect((err) => {
    if (!err) {
        console.log('connection created');
    }
    const newDB = client.db("YourNewDatabase");
    newDB.createCollection("YourCreatedCollectionName"); // This line i s important. Unless you create collection you can not see your database in mongodb .

})

Now run this index file by the following command in your terminal

node index.js
