Node.js: TypeError: Router.use() requires a middleware function but got a Object

Question

hi m trying to get an index page but it is showing an error: TypeError: Router.use() requires a middleware function but got a Object, structure: views>attendance>index.ejs how can I resolve this error,

controller:

   in controller I write this path:
   router.get('/attendance', (req, res) => res.render('attendance/index'));

app.js

  require('./models/Attendance');

  const attendanceController = require('./controllers/attendanceController');

  app.use('/attendance', attendanceController);

Answer 1

The only reason I can imagine for this not working is incorrect exports/imports.

You need to export the router like this in the controller file:

module.exports = router;

Also, by doing router.get('/attendance'... and applying it app.use('/attendance', , the application will listen for requests directed to /attendance/attendance endpoint. I'd change the controller to:

router.get('/', (req, res) => res.render('attendance/index'));
