AAA - Authentication Authourization Accounting -Front End

[aadeaina]

Front-End (React) Responsibilities:

1. User Interface:

   • Present the login and registration forms to users and handle form validation before submitting requests to the back-end.
   • Store authentication tokens (e.g., JWTs) securely in the client (e.g., in localStorage or sessionStorage) and send them in API requests.
   • Manage user sessions on the client side, including handling token expiration and refreshing tokens if necessary.

2. Conditional Rendering:

   • Control which parts of the UI are visible based on the user's authentication state and permissions. For example, hide or disable certain features for unauthorized users.
   • Show appropriate messages or redirect users if they try to access restricted areas without proper authorization.

3. Request Handling:

   • Attach authentication tokens to API requests made to the Django back-end.
   • Handle errors returned by the back-end, such as unauthorized or forbidden errors, and guide the user accordingly (e.g., redirect to the login page, show error messages).

4. Local State Management:

   • Maintain the user's authentication state (e.g., logged-in user data) and keep it in sync with the back-end's state.
   • Implement logout functionality that clears the authentication token and local state related to the user session.

Security Considerations:

• Do not trust the front-end with sensitive data or authorization logic: The front-end can be easily manipulated by users or attackers, so all critical security checks must happen on the back-end.
• Token Expiration and Refresh: Implement token expiration policies on the back-end and provide mechanisms to refresh tokens securely. The front-end should manage the token lifecycle and handle token refresh requests.
• HTTPS: Ensure that all communication between the front-end and back-end happens over HTTPS to protect data in transit.

By following this distribution of responsibilities, you ensure that your application is both secure and user-friendly, with the front-end handling user interactions and the back-end enforcing strict security controls.
