How to fix: Express.js request body is undefined.

Node.js / February 25, 2023 / TopCode / 0

Introduction

If you are using the latest express version in Node.js then you may face the above exception while accessing HTTP request body. In the earlier versions of express, there was no such type of issue in the library.

In the update of July2020, express.bodyParser() is no longer bundled as part of express. Therefore User need to install this dependency separately before accessing the body.

body-parser

Body-parser is a middleware and it parses incoming HTTP request bodies in a middleware before your handlers, available under the req.body property.

You can install it using following command

npm install body-parser

The following code shows how you can include body-parser before accessing the request body. Make sure you are loading body-parser before its access.

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

app.post('/home' (res, req) => {
  console.log('body: ', req.body)
  console.log('query: ', req.query) 
})

app.listen(3000)

Conclusion

Hope your error will be solved by applying the given solution. #Happy Coding #TopCode
