问题 I am working on a NextJS site that has some custom styling that is being applied via MaterialUI's makeStyles. It works fine on the first load and then undoes all of the custom work on the second.

问题 What's the best way to prevent a particular user from accessing a route and any of its subroutes in react-router ? e.g. I have a route /admin/ and it has many other subroutes like /admin/create-user , /admin/settings , etc. Is there another way of preventing users from accessing these routes without indicating on each component some condition like so? if (user.role.name !== "Admin") { return ( <div className="error-page"> <h1>Sorry, you don't have rights to access this page.</h1> </div> ); }
