-### Populate body property

-Without the use of body parsing middleware `req.body` will return undefined. To get express to populate `req.body` you need to use middleware within server.js:
-
-```js
-app.prepare().then(() => {
-  const server = express()
-  server.use(express.urlencoded({ extended: true }))
-  server.use(express.json())
-})
-```
