// If you are using Express 4.16+ you don't have to import body-parser anymore. 
// You can do it just like this:

app.use(express.urlencoded({extended: true}));
app.use(express.json()) // To parse the incoming requests with JSON payloads

const express = require('express');

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

If you are using the latest express module use this:

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

// 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}));

app.use(bodyParser.urlencoded());

app.use(bodyParser.json());

// on the js code, its as follows:
var bodyParser = require('bodyParser');

// Body 
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
