How to access the request body when POSTing using Node.js and Express?

by

Starting from express v4.16 there is no need to require any additional modules, just use the built-in JSON middleware:

app.use(express.json())

Like this:

const express = require('express')

app.use(express.json())    // <==== parse request body as JSON

app.listen(8080)

app.post('/test', (req, res) => {
  res.json({requestBody: req.body})  // <==== req.body will be a parsed JSON object
})

Note – body-parser, on which this depends, is already included with express.

Also don’t forget to send the header Content-Type: application/json
