Error: Route.get() requires a callback function but got a [object Undefined] while using imported function

I am checking if a user is logged in a route called forum. I am importing it like this. The file is routes/forum.js

const isloggedinimport = require('../index')

I have the function on index.js

const isloggedin = (req,res,next) => {
  if(req.user) {
    next()
  }
  else {
    res.render('loginerror',)
  }
}

I am exporting with

module.exports = isloggedin

When I try to run this


router.get('/', isloggedinimport.isloggedin, (req, res) => { 
    res.render('monitors/monitorhome')
});


module.exports = router

I get the error that Route.get() requires a callback function but got a [object Undefined]

The error is on this line

router.get('/', isloggedinimport.isloggedin, (req, res) => {

How do I fix this?

Had the same problem and fixed it by adding brackets around the function you want to export:

module.exports = {isloggedin};

When exporting the function, try using the following code:

module.exports.isloggedin = isloggedin

This will set the property isloggedin to the function so that when you call isloggedinimport.isloggedin, it will access the function properly. Alternatively, you could use the following code to export your function:

module.exports = isloggedin

and then use this code to import the function:

const isloggedin = require('../index')

...

router.get('/', isloggedin, (req, res) => { 
    res.render('monitors/monitorhome')
});
