express js body parser deprecated code example

Example 1: express bodyparser deprecated

The package bodyParser is deprecated. You will get this warning with these lines of code:

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

If you are using Express 4.16+ you can now replace those lines with:

app.use(express.json()); 
app.use(express.urlencoded()); //Parse URL-encoded bodies

Example 2: express bodyparser deprecated

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 }));

Example 3: body parser deprecated

// 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}));
