//require the mongoClient from mongodb module
var MongoClient = require('mongodb').MongoClient;

//mongodb configs
var connectionUrl = 'mongodb://localhost:27017/myproject',
    sampleCollection = 'chapters';

//We need to insert these chapters into mongoDB
var chapters = [{
    'Title': 'Snow Crash',
    'Author': 'Neal Stephenson'
},{
    'Title': 'Snow Crash',
    'Author': 'Neal Stephenson'
}];

MongoClient.connect(connectionUrl, function(err, db) {

  console.log("Connected correctly to server");

  // Get some collection
  var collection = db.collection(sampleCollection);

  collection.insert(chapters,function(error,result){
    //here result will contain an array of records inserted
    if(!error) {
      console.log("Success :"+result.ops.length+" chapters inserted!");
    } else {
      console.log("Some error was encountered!");
    }
    db.close();
  });
});

I needed to create a mongodb atlas database, you can do it for free and create a cluster and you can get the connection by choosing drivers option

const { MongoClient, ServerApiVersion } = require('mongodb');
const uri = "mongodb+srv://username:password@cluster0.lbynzll.mongodb.net/?retryWrites=true&w=majority";
// Create a MongoClient with a MongoClientOptions object to set the Stable API version
const client = new MongoClient(uri, {
  serverApi: {
    version: ServerApiVersion.v1,
    strict: true,
    deprecationErrors: true,
  }
});

var sampleCollection = 'chapters';

var chapters = [{
	'Title': 'Snow Crash',
	'Author': 'Neal Stephenson'
}, {
	'Title': 'Snow Crash',
	'Author': 'Neal Stephenson'
}];
async function run() {
  try {
    // Connect the client to the server	(optional starting in v4.7)
    await client.connect();
    // Send a ping to confirm a successful connection
    await client.db("admin").command({ ping: 1 });
    console.log("Pinged your deployment. You successfully connected to MongoDB!");
    try {
	await client.db("mydb").createCollection("chapters");
        console.log("Collection chapters created succesfully!");
    } catch {
	console.log("Collection chapters already exists!");
    }
    var result = await client.db("mydb").collection("chapters").insertMany(chapters);
    // console.log("Success: " + JSON.stringify(result, null, 4) + " chapters inserted!");
    console.log("insertedIds: " + result.insertedCount);
  } finally {
    // Ensures that the client will close when you finish/error
    await client.close();
  }
}
run().catch(console.dir);
