const contacForm = () => {

}
module.exports = contacForm ;

const express = require('express');
const mongo = require('connect-to-mongodb');
const app = express();

//root directory path of your project 
const rootDir = process.cwd() ;
// mongoDB path on local system ;
const mongoPath = 'mongodb://localhost:27017/mydbname' ;
const db = mongo( rootDir , mongoPath );

// for read data from mongodb ;
app.get('/get' , async (req , res) => {
    // read data from database ;
