Answer 1

First you need to initialise bodyParser like that👇

const bodyParser = require('body-parser')

Then configure it like that 👇

const jsonParser = bodyParser.json()

var urlencodedParser = bodyParser.urlencoded({ extended: true })

So in your url post 👇

app.post("/login", urlencodedParser, (request, response)=>{
const email = req.body.email
//Some code

} )

Answer 2

Express now has its own support

app.use(express.json())
app.use(express.urlencoded({ extended: true }))

And you can access it everywhere directly from the request object. Like so:

req.body
