Zustand offers minimal API state management for React. No providers wrap your app. Stores are hooks. Subscriptions are automatic and performant. This simplicity makes Zustand attractive for projects not needing Redux complexity.
Store Creation
Create stores with simple functions returning state and actions. Use selectors to access specific state slices. Multiple stores separate concerns cleanly. Middleware adds persistence, devtools, and more.
- Create stores with create() returning state and actions
- Use selectors to minimize re-renders from state changes
- Implement middleware for persistence and logging
- Split stores by domain for better organization
- Combine with React Query for server state
Performance Patterns
Zustand re-renders components only when selected state changes. Use shallow equality for object comparisons. Slice selectors prevent unnecessary updates. These patterns maintain performance at scale.
