body-parser node

1. Import the Express module:

const express = require('express');

1. Create an instance of the Express application:

const app = express();

1. Import and use the body-parser middleware:

const bodyParser = require('body-parser');
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));

Explanation:

• express is imported to access the functionalities provided by the Express.js framework.
• An instance of the Express application is created using express().
• The body-parser middleware is imported to handle parsing of incoming request bodies in different formats such as JSON and URL-encoded data.
• bodyParser.json() is used to parse incoming requests with JSON payloads.
• bodyParser.urlencoded({ extended: true }) is used to parse incoming requests with URL-encoded payloads, allowing for nested objects in the encoded data by setting the extended option to true.
