if you are starting new with Node JS, you will probably face this problem, while submitting the form to a post URL.

The problem you will face is getting a empty req.body in-spite of sending the form properly. To resolve this issue, you have make two change in your current system.

Add the following to the form element

enctype="application/x-www-form-urlencoded"

The second thing, in your index.js in root add the following lines to unable the form.

app.use(express.urlencoded({
    extended: true
