Best Practices
Structure:
✓ Keep stores focused
✓ Use slices for large stores
✓ Separate actions from state
✓ Use TypeScript for safety
Performance:
✓ Use selectors to minimize re-renders
✓ Use shallow comparison for objects
✓ Subscribe only to needed state
✓ Avoid selecting entire store
Patterns:
✓ Use middleware for cross-cutting concerns
✓ Persist only necessary state
✓ Use immer for complex updates
✓ Reset stores in tests
Conclusion
Zustand provides simple, powerful state management with minimal boilerplate. Use selectors for performance, middleware for persistence and devtools, and slices for organizing larger stores. Its hooks-based API integrates naturally with React while remaining flexible for complex use cases.
