    Try this code once :

    var express = require('express');
var router = express.Router();
const { MongoClient } = require('mongodb');

// Define MongoDB URL and Database Name
const url = 'mongodb://localhost:27017';
const dbName = 'your_database_name'; //Enter your database name here

// Function to establish connection
async function connectToDB() {
  try {
    const client = await MongoClient.connect(url);
    console.log("Connected to MongoDB");
    return client.db(dbName);
  } catch (err) {
    console.error("Error connecting to MongoDB:", err);
    throw err;
  }
}

// Establish MongoDB connection when the server starts
connectToDB()
  .then(() => console.log("Backend connected to MongoDB"))
  .catch(err => console.error("Error connecting to MongoDB during server start:", err));

// GET home page
router.get('/', function (req, res, next) {
  res.render('index', { title: 'Express' });
});


router.post("/signup", async function (req, res) {
  console.log("first_name: " + req.body.first_name);
  console.log("last_name: " + req.body.last_name);



  res.send("User signed up successfully");
});
