Pull request overview
This PR aims to prevent rapid repeated clicks on the “Draw Next Quote” button from triggering overlapping drawNextCard executions, reducing redundant incrementQuotesDiscovered calls and avoiding UI race conditions during the flip animation.
Changes:
- Add an early return in
drawNextCardwhenisFlippingis already true. - Update the
useCallbackdependency array to includeisFlipping.
💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.

The useCallback dependency list still doesn’t include everything used inside drawNextCard (notably userId and fetchQuoteDeck). This can leave the callback capturing stale values (e.g., userId after login/logout), which can cause incrementQuotesDiscovered / deck refresh behavior to run against the wrong user or not run when it should. Suggest memoizing fetchQuoteDeck with useCallback and adding userId/fetchQuoteDeck to the dependencies (or refactor to avoid closing over them).

This change optimizes the
drawNextCardfunction inapp/affirmations/page.tsxby adding a check for theisFlippingstate. Previously, rapid clicking on the "Draw Next Quote" button would trigger multiple overlapping executions, leading to redundant database calls (incrementQuotesDiscovered) and potential race conditions.The fix ensures that the function returns early if an animation is already in progress (throttled by the 600ms flip duration), effectively reducing database load and ensuring consistent UI behavior.
Measured impact: In a simulated benchmark of 10 rapid clicks, database calls were reduced from 10 to 1.
