Is there a way to check if user is logged in using express.Router middleware?

Question

How can I insert isLoggedIn as a condition to the get request using router.route?

const controller = require('./controller');
const Router = require('express').Router;
const router = new Router();

function isLoggedIn(req, res, next) {
  if (req.isAuthenticated())
    return next();
  res.redirect('/');
}

router.route('/')
  .get((...args) => controller.find(...args))

I assume that the ...args are (req, res, next) I tried

router.route('/')
      .get(isLoggedIn(...args) => controller.find(...args))

But I get

.get((isLoggedIn(...args)) => controller.find(...args))
                ^

The docs say, that you can assign multiple handlers to one route. Like this:

app.use('/user/:id', function (req, res, next) {
  console.log('Request URL:', req.originalUrl)
  next()
}, function (req, res, next) {
  console.log('Request Type:', req.method)
  next()
})

In your case the coding looks like the following

router.get('/', isLoggedIn, controller.find);
