The official documentation can be found here.

Nothing happens when trying to create a MongoDB database through a Node.js file

I am following W3Schools.com’s ‘Node.js MongoDB’ tutorial. My action.js file contains the following code:

var mongo = require('mongodb').MongoClient;
var url = "mongodb://localhost:27017/mydb";

mongo.connect(url, function (err, db) {
  if (err) throw err;
  console.log("Database created!");
  db.close();
});

When I try to run the file using node action.js, nothing happens. Even after going through several forums I can’t figure out what is going on.
This is the same question but at least that person is getting some error, which I’m not.

Terminal screenshot after executing Node.js command

mongod --version
db version v8.0.1
Build Info: {
    "version": "8.0.1",
    "gitVersion": "fcbe67d668fff5a370e2d87b9b1f74bc11bb7b94",
    "modules": [],
    "allocator": "tcmalloc-gperf",
    "environment": {
        "distmod": "windows",
        "distarch": "x86_64",
        "target_arch": "x86_64"
    }
}
mongosh --version
2.3.2

I tried changing the //localhost:27017 to 127.0.0.1:27017 as lots of other solutions have mentioned but it didn’t make any difference.

    Try instead this script which works:

    
const { MongoClient } = require('mongodb');

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

// Database Name
const dbName = 'mydb';

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');

    // the following code examples can be pasted here...

    return 'done.';
}

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

    Did you start the server mongodb before all?
    Below is the string to start the server on my linux machine

    sudo mongod –noauth –port 27017 –dbpath /var/lib/mongodb
