Tasks & Issues

1. Critical Issues

• 1.1 Fix missing del import in store/index.js

  • Line 3 imports get, set from idb-keyval but del is used on line 13
  • Add del to the import statement
  • This will cause a ReferenceError when removeItem is called

• 1.2 Fix hydration flag initialization

  • The onRehydrateStorage callback uses store.setState() before store is fully initialized
  • Creates a circular reference issue preventing app from loading
  • Options:
    • A) Initialize _hydrated: true by default (simplest)
    • B) Use Zustand's persist middleware built-in hydration detection
    • C) Move hydration callback outside store creation

• 1.3 Consolidate duplicate storage implementation

  • Storage is defined in both store/index.js AND store/middleware/persistence.js
  • The middleware file exports idbStorage but it's not being used
  • Decision needed: Use one or the other, not both

2. Architectural Improvements

• 2.1 Add error handling

  • Add try/catch blocks around IndexedDB operations
  • Implement fallback if IndexedDB fails or is unavailable
  • Add user feedback for errors (toast notifications?)

• 2.2 Add partialize option to persist middleware

  • Currently saves ALL state including _hydrated flag and route
  • Should use partialize: (state) => ({ user: state.user, items: state.items })
  • Prevents unnecessary data in IndexedDB

• 2.3 Add basic CSS reset to index.html

  • No base styles, margins, or font settings currently
  • Consider adding minimal reset or normalize.css

• 2.4 Add loading states for async operations

  • No loading indicators for add/remove item operations
  • Consider adding optimistic updates

3. Nice to Have

• 3.1 Add TypeScript types (optional)

  • JSDoc comments for better IDE support
  • Or migrate to .ts files with no-build setup

• 3.2 Add cross-tab synchronization

  • README mentions optional sync.js middleware
  • Implement BroadcastChannel for cross-tab state sync

• 3.3 Add route history management

  • Integrate with browser history API
  • Support back/forward navigation

• 3.4 Add unit tests

  • Test store actions and selectors
  • Test component rendering
  • Test persistence layer
