🧹 Refactor useCardSettings hook to remove set-state-in-effect directive by is0692vs · Pull Request #498 · Hiroki-org/github-user-summary

is0692vs · 2026-07-17T06:51:41Z

🎯 What: Removed hydration state and useEffect initialization from useCardSettings hook. \n\n💡 Why: Simplifies the hook by allowing the initial state values to be returned directly from the loadCardSettings function without triggering unnecessary cascading renders from a hydration effect. This allows the removal of eslint-disable-next-line react-hooks/set-state-in-effect directives.\n\n✅ Verification: Verified npm run test passes locally. Confirmed the initial server render matches with typeof window !== 'undefined' check within the initialization callbacks.\n\n✨ Result: A cleaner and more optimized React hook implementation without eslint disable directives.

No security issue was identified in the changed code.

src/hooks/useCardSettings.ts

Important Files Changed

Filename	Overview
src/hooks/useCardSettings.ts	The hook no longer waits for client-side storage hydration before persisting settings, so SSR defaults can overwrite saved user settings.
src/components/CardGeneratorModal.tsx	The modal now calls `useCardSettings` without a mounted gate, while still invoking the hook before the closed-modal early return.

### Issue 1 of 1
src/hooks/useCardSettings.ts:19-21
**Hydration Defaults Overwrite Storage**

SSR initializes this hook with default settings because `window` is unavailable, and this effect now saves those defaults as soon as the client hydrates. Since `CardGeneratorModal` calls the hook before returning `null`, an existing localStorage customization can be overwritten before the user opens the modal.

Warning

Review limit reached

@is0692vs, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 42 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.
