bodyparser is deprecated

                                    app.use(bodyParser.urlencoded({ extended: true }))

                                    body-parser has been deprecated from express v4.* 
Use body-parser package instead.
npm i body-parser

import bodyParser from "body-parser";//for typscript code only, use require for js
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));

                                    const express = require('express');

app.use(express.urlencoded({ extended: true }));

                                    const express = require('express');

app.use(express.urlencoded({ extended: true }));
app.use(express.json());

                                    // bodyParsor is deprecated, most of the functionality is included in express
// on epxress 4.16 and above just replace bodyParser with express
// e.g 
const express = require('express')
app.use(express.urlencoded({extended: true}));
