Here in this code, I have created two pages with the URL ” /new-product” and “/product”. In a new-product page, there will be a form created through a method req.send() using HTML syntax. After submitting the form this website will redirect to a new page that has URL “/product” and data of webpage is print to console.

const express = require('express');
const app = express();
const bodyParser = require('body-parser');
app.use(bodyParser,urlencoded({extended :true});
     console.log("You are into /new-product");
     req.send("<form method="Post", action="/product"> <input type="text" name="msg"><br><button type ="submit">Click Here </button></form>")
     console.log("You are into /new-product");
     req.send("The submission has done successfully");
