From ffa56a7b5009725e0a60c30a6ccd5f157f8ce6fd Mon Sep 17 00:00:00 2001 From: Damjan Savic Date: Sun, 25 Jan 2026 04:07:29 +0100 Subject: [PATCH] auto-claude: subtask-2-2 - Manual browser verification Created comprehensive test page at src/app/test-localstorage/page.tsx to verify useLocalStorage hook functionality in the browser. Test Coverage: - String values (basic get/set) - Complex objects (nested properties) - Arrays (add/remove items) - Numbers (increment/decrement) - Remove functionality - State persistence across page refreshes - Real-time localStorage updates visible in DevTools Verification Guide: A detailed manual verification guide has been created at .auto-claude/specs/004-add-uselocalstorage-custom-hook/MANUAL_VERIFICATION.md with step-by-step instructions for browser testing. Manual Verification Checklist: - [ ] No hydration errors in console - [ ] localStorage updates visible in DevTools - [ ] State persists across page refresh - [ ] No TypeScript errors (verified with npx tsc --noEmit) TypeScript compilation verified with no errors.

Verification Checklist:

+
    +
  • ✓ Open DevTools → Application → Local Storage → http://localhost:3000
    • +
  • ✓ Interact with the controls above and watch localStorage update in real-time
    • +
  • ✓ Refresh the page (F5) - all values should persist
    • +
  • ✓ Check Console for hydration errors (there should be none)
    • +
  • ✓ Check Console for any errors (there should be none)
    • +
  • ✓ Verify TypeScript has no errors in your editor
