Example of protected route

// Test authenticated route
// Use this route to test if the front-end is able to access this route 
// Front-end needs to pass the token in the request header (header name: "Authorization")
router.get('/authenticated/test', passport.authenticate('jwt', { session: false }), (req, res) => {
    console.log('Authentication successful');
    res.json({
        message: 'Successfully authenticated',
        user: req.user
    });
});
