As part of my React learning journey, I built a simple yet powerful password generator app during Days 6 and 7. This project was not just a UI exercise: it was an immersion into React hooks like useCallback, useEffect and useRef, applied to achieve a fast, reliable and easy-to-use experience.
Main features: password length control · enable or disable numbers and special characters · copy to clipboard with one click · auto-generate when options change
useCallback: I memoized the password generation logic to avoid unnecessary re-renders and optimize the app's performance, which is essential when handling functions derived from options that change frequently.
useEffect: I orchestrated the side effects that need to run when password settings change to trigger automatic regeneration and keep the UI synchronized with the state.
useRef: I used references to get the generated value and copy it to the clipboard directly and cleanly, avoiding unnecessary re-renders and ensuring a smooth interaction.

Proposed improvements and security considerations: add a strength meter with entropy calculation, unit and integration tests, avoid persistent storage of sensitive passwords, offer options to exclude ambiguous characters and validate generation in high-security contexts. I would also recommend reviewing clipboard behavior across different browsers and ensuring the app is served in a secure HTTPS context.
