MY CODE :-
connection.js

import { MongoClient } from "mongodb"


const state={
    db:null
}
export const connectToDb = async (cb) => {
    const url='mongodb://localhost:27017'
    const dbName='techtrinkets'

    MongoClient.connect(url,(err,client)=>{
        if(err) return cb(err)
        state.db=client.db(dbName)
        console.log(state.db);
    })
    cb();
}

export const getDB = () => {
    return state.db
}

inde.js

import express from "express";
import dotenv from "dotenv"
import { connectToDb } from './db/connection.js'

const app = express()
dotenv.config()

//Database Connection
connectToDb((err)=>{
    if(err) return console.log("Database Error");
    console.log("Database Connected");
})

app.listen(process.env.PORT, () => {
    console.log("Server Started port:"+process.env.PORT);
})

Try with 127.0.0.1 in your uri instead of localhost
