cannot read property of 'get' undefined in the express router

Question

My code is as shown below: app.js ``` const app = express(); const itemsRouter = require('./routes/items.js'); app.use(bodyParser.urlencoded({ extended: true })); app.use('/items', itemsRouter); ``` items.js ``` const router = require('express').router; router.get('/itemTest', (req, res) => { res.json({ sucess: true }); console.log(`the parametrs are ${req.body.item_name} ${req.body.item_post}`); }); module.exports = router; ``` But here somehow, I am not able to get the router working and it says that can not read property 'get' of undefined. the error stack is as shown below: ``` TypeError: Cannot read property 'get' of undefined at Object. (C:\Users\anand\quFlipApi\routes\items.js:5:7) at Module._compile (module.js:570:32) at Object.Module._extensions..js (module.js:579:10) at Module.load (module.js:487:32) at tryModuleLoad (module.js:446:12) at Function.Module._load (module.js:438:3) at Module.require (module.js:497:17) at require (internal/module.js:20:19) at Object.

Accepted Answer

There are two problems here:

- It's `express.Router` and not `express.router`.

- You need to create a new instance of `express.Router` (e.g. `var router = new express.Router()`) instead of trying to using the constructor directly as an instance.
