I'm working on enhancing the security of my Next.js application by implementing protected routes. I'd like to hear about different strategies or approaches that developers have found successful when using the Next.js app router. I understand that the "best" approach can be subjective and may vary depending on the project's requirements. However, I'm interested in learning about various perspectives and experiences. If you've dealt with protected routes in Next.js, could you please share the approach you found effective and the reasons behind your choice? Your insights would provide valuable guidance as I make decisions about securing routes in my application.

Create a Higher-Order Component (HOC): You can create a HOC that wraps your pages to handle the authentication logic, which will check if the user is authenticated before rendering the page. If the user is not authenticated, you can redirect them to the login page:

import { useRouter } from 'next/router';
import { useEffect } from 'react';

const RequireAuth = (WrappedComponent) => {
  return (props) => {
    const router = useRouter();

    // Check if user is authenticated, if not, redirect to login
    useEffect(() => {
      if (!userIsAuthenticated) {
        router.push('/login');
      }
    }, []);

    return <WrappedComponent {...props} />;
  };
};

export default RequireAuth;

Use the HOC for Protected Routes: Wrap your protected pages with the RequireAuth HOC to ensure that they are accessible only to authenticated users.

import RequireAuth from '../components/RequireAuth';

const ProtectedPage = () => {
  return <div>This is a protected page.</div>;
};

export default RequireAuth(ProtectedPage);

Define Protected Routes: You can create a configuration file where you define the protected routes. This way, you can manage them centrally and reduce redundancy.

export const protectedRoutes = [
  '/protectedPage1',
  '/protectedPage2',
  // Add more protected routes here
];

Apply Route Protection in App Router: In your Next.js app router, you can loop through the protected routes and apply the RequireAuth HOC to them.

import { protectedRoutes } from '../utils/routes';

function MyApp({ Component, pageProps }) {
  const isProtectedRoute = protectedRoutes.includes(router.pathname);

  return isProtectedRoute ? <RequireAuth Component={Component} {...pageProps} /> : <Component {...pageProps} />;
}

export default MyApp;

Using a HOC and a configuration file, you can easily manage protected routes and keep your codebase more maintainable.

  • If I intend to verify user authentication through Redux or a context API, I'm seeking clarification on whether this method operates on the client-side or the server-side of the application architecture. In other words, I would like to understand whether the authentication check occurs within the user's browser environment or if it involves communication with the server. Any insights provided regarding the nature and implementation of this approach would be greatly appreciated. Thanks for your valuable time. – Ehtisham Ali Aug 25 '23 at 16:29
