Securing Pages and Implementing User Context on Frontend

[doziestar]

Description

We need to implement a system for securing pages based on user authentication and authorization, as well as provide a global user context throughout the frontend application.

Tasks

1. Implement a higher-order component (HOC) for protected routes:

   • Create a withAuth HOC that checks for user authentication
   • Implement redirection to login page for unauthenticated users
   • Add support for role-based access control in the HOC

2. Set up user context using React Context API:

   • Create a UserContext with user information and authentication status
   • Implement a UserProvider component to wrap the application
   • Create custom hooks for accessing and updating user context

3. Integrate user context with authentication flow:

   • Update user context on successful login
   • Clear user context on logout
   • Implement automatic context update on token refresh

4. Secure individual pages:

   • Apply the withAuth HOC to pages requiring authentication
   • Implement role-based page access using the Authorization Service

5. Create a navigation guard:

   • Implement a component that checks user permissions before rendering links
   • Hide or disable navigation items based on user roles

6. Implement client-side role-based content rendering:

   • Create a component for conditional rendering based on user roles
   • Use the Authorization Service to check permissions for specific actions

7. Set up persistent authentication:

   • Implement a mechanism to restore user session on page reload
   • Use secure storage (e.g., HttpOnly cookies) for storing authentication tokens

8. Handle authentication timeouts:

   • Implement a mechanism to detect token expiration
   • Show a session timeout modal and prompt for re-authentication

9. Create a user profile page:

   • Implement a page to display user information
   • Add functionality to update user profile information

10. Implement error boundaries:

    • Create error boundary components to catch and display authentication errors
    • Implement graceful error handling for authorization failures

11. Add loading states:

    • Implement loading indicators while checking authentication status
    • Add skeleton screens for protected pages while loading user data

12. Test protected routes and user context:

    • Write unit tests for the withAuth HOC and user context hooks
    • Implement integration tests for protected pages
    • Perform end-to-end testing of the entire authentication flow

Acceptance Criteria

• All pages requiring authentication are properly secured
• Unauthenticated users are redirected to the login page when accessing protected routes
• User context is available throughout the application and updates correctly
• Navigation items and page content are displayed based on user roles and permissions
• User sessions persist across page reloads
• Authentication timeouts are handled gracefully
• Error boundaries catch and display authentication and authorization errors
• Loading states are shown while authentication checks are performed
• Unit tests cover the withAuth HOC and user context hooks
• Integration tests verify the behavior of protected pages
• End-to-end tests cover the entire authentication and authorization flow
