Creating a expressjs middleware that accepts parameters

Question

I am trying to create a middleware that can accept parameters. How can this be done?

example

app.get(\'/hasToBeAdmin\', HasRole(\'Admin\'), function(         


        

Answer 1

app.get('/hasToBeAdmin', (req, res, next) => {
  hasRole(req, res, next, 'admin');
}, (req,res) => { 
    // regular route 
});

const hasRole = (req, res, next, role) => {
   if(role != user.role){
      res.redirect('/NotInRole');
   }
   next();
};
