POST request body not available in Express middleware 'req'

I have an odd query that has really stumped me.

I have created this Express middleware:

const express = require('express')
const bodyParser = require('body-parser')
var router = express.Router()
router.use(bodyParser.urlencoded({ extended: false }))
router.use(bodyParser.json())
app.use(router)

router.use((req, res, next) => {
  console.log(req.body)
})

router.post((req, res) => {
  ...
})

Whever I try to log the body in the router.post, it logs the correct body. However, when I try to log it in the router.use (as shown above), it only returns an empty object. Any thoughts of how I can get the body in middleware? Thanks!

Only isssue I see according to the official documentation is that you've to set the router to the app after declaring all the middlewares as said in the below attached image,

enter image description here

which means you code should be changed to

const express = require('express')
const bodyParser = require('body-parser')
var router = express.Router()
router.use(bodyParser.urlencoded({ extended: false }))
router.use(bodyParser.json())

router.use((req, res, next) => {
  console.log(req.body)
})

router.post((req, res) => {
  ...
})

//setting the router as a middleware after declaring all the routes and middleware functions.
app.use(router)
