How to form data in Express.js?

Forms are widely used in the web to submit or fetch some information for the visitors. Multipart/form-data is a type of encoding. It is important to note that it works only with POST method. This is also important while using uploading files.

// Form Data using GET Method
app.get("/signupdata", (req, res) => { 
     const data = req.query;
     res.render("signupdata", data)
// Form Data using POST Method
const bodyParser = require("bodyParser")
app.use(bodyParser.json())"/signupdata", (req, res) => { 
     res.render("signupdata", req.body)
app.listen{4000, () => {
     console.log('Server Started..!');
