Can't connect to a MongoDB using Node.js

Can't connect to a MongoDB using Node.js.

This is my code (mdb.js):

var MongoClient = require('mongodb').MongoClient, format = require('util').format;

MongoClient.connect('mongodb://localhost:3000', function(err,db){

    if(err){
         throw err;
    } else {
         console.log("Connected");
    }
    db.close();
});

node mdb.js prints MongoError:

First of all please verify that have you changed your default database port from 27017 to 3000 or not. If not changed then please try the below code it's working for me

 const { MongoClient } = require("MongoDB");

 // Connection URL
 const url = "mongodb://localhost:27017";
 const client = new MongoClient(URL);

 // Database Name
 const dbName = "myProject";

 async function main() {
    // Use connect method to connect to the server
    await client.connect();
    console.log("Connected successfully to server");
    const db = client.db(dbName);
    const collection = db.collection("documents");

    // return "done.";
 }

main()
  .then(console.log)
  .catch(console.error)
  .finally(() => client.close());

Also here is I attached a my screenshot with the output Sample output example

Your error explaining itself. Mongo cant find default db path B:/data/db.

Create this folder or on start up choose another DB directory 

mongod --dbpath yourPath(C:\myDb)

Also default mongo port is 27017 so you need to change connection string like this "mongodb://@localhost:27017/dbYouWant"

Hope this helps.
