React Authentication: Protected Pages

Create a PrivateRoute Component

Implement a PrivateRoute component that protects a route and redirects unauthenticated users to a login page.

Expected output: A working PrivateRoute component that restricts access based on authentication state.

Hint: Use React Router's Navigate and Outlet components to conditionally render routes.

Manage Authentication State with Context

Create a React Context to hold authentication state and provide login/logout functions.

Expected output: A context provider that allows components to access and update authentication status.

Hint: Use React.createContext and a provider component to share auth state across your app.

Protect Multiple Routes

Use your PrivateRoute component to protect multiple routes like Dashboard, Profile, and Settings.

Expected output: Only authenticated users can access the protected routes; others are redirected.

Hint: Wrap these routes inside the PrivateRoute component in your routing configuration.

Protected routes are implemented by checking the user's authentication status before rendering a route's component. This is commonly done using a wrapper component like PrivateRoute that either renders the component if authenticated or redirects to login otherwise.

Authentication state can be managed using React Context API, Redux, or other state management libraries. The state should reflect whether the user is logged in and provide methods to update this state on login/logout.

Client-side route protection improves user experience but does not guarantee security because users can manipulate client code. Server-side checks and secure APIs are necessary to fully protect sensitive data.
