express body-parser deprecated

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

                                    /** @format */

const express = require("express");
const app = express();
const mongoose = require("mongoose");
const bodyParser = require("body-parser");
const PORT = process.env.PORT || 3000;

// parse application/x-www-form-urlencoded
app.use(bodyParser.urlencoded({ extended: false }));

// parse application/json
app.use(bodyParser.json());

//connecting to db
try {
    mongoose.connect('mongodb://localhost/YOUR_DB_NAME', {
        useNewUrlParser: true,
        useUnifiedTopology: true,
      	useCreateIndex: true,
      }, () =>
      console.log("connected"));
  } catch (error) {
    console.log("could not connect");
  }

app.get("/", (req, res) => {
  res.send("home");
});

app.listen(PORT, () => console.log(`Server is listening on port ${PORT}`));

                                    const express = require('express');

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

                                    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 }));

                                    If you are using the latest express module use this:

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