Today's work centered around developing the Logout Functionality to improve session management and provide users with a seamless experience when they exit the application. This feature is essential for ensuring app security and removing sensitive session information.
The session kicked off with the design of the Logout Component. This included crafting a specific function to manage user logout by erasing the session data stored in both the frontend and backend. Here’s a breakdown:
-
Frontend Adjustments:
- I made use of
localStorageandsessionStorageto keep the user's authentication tokens. The logout function clears these storages, effectively logging the user out by removing any remaining session tokens. - This function was linked to a logout button in the navigation bar for user convenience.
- I made use of
-
Backend Adjustments:
- On the server side, I set up an endpoint to invalidate tokens stored on the backend, preventing any potential misuse. This included clearing token-related information from the database or cache as necessary.
- I also added appropriate response codes to notify the client of a successful logout.
-
Redirect Feature:
- After logging out, users are redirected to the Sign-In Page using React Router's
useNavigatehook, ensuring a smooth transition and preventing access to restricted areas post-logout.
- After logging out, users are redirected to the Sign-In Page using React Router's
-
User Experience Improvements:
- A confirmation modal was introduced to help avoid accidental logouts.
- A toast notification was added to inform users of a successful logout.
Following the TDD approach, I created test cases to verify:
- The session tokens are cleared properly.
- The user is redirected to the sign-in page.
- The backend token invalidation functions correctly.
By the end of the session, the logout functionality was fully integrated and tested, providing a secure and user-friendly method for ending sessions. Next, I plan to look into adding a session expiration log.
