In React, protecting routes ensures that only authenticated users can access certain pages. This is typically done using React Router along with authentication state management.

Steps to protect routes:

1. Maintain Auth State – Store the user’s authentication status (from login) in state, context, or a global store like Redux.

2. Create a PrivateRoute Component – A wrapper that checks if the user is logged in:

   • If authenticated, render the requested component.

   • If not authenticated, redirect to the login page.

3. Token Verification – Check the presence and validity of a token (e.g., JWT) in cookies or localStorage. Optionally verify it with the backend.

4. React Router Setup – Use <Route> for public pages and your PrivateRoute for secure ones.

5. Logout Handling – Clear auth state and redirect to login.

Best Practices:

• Use HTTP-only cookies for tokens to prevent XSS.

• Double-check authorization on the backend (frontend checks can be bypassed).

In short, React route protection involves checking authentication state and redirecting unauthenticated users to safe entry points.
