What problem does it solve?
Zustand 5 patterns reduce boilerplate and prevent inefficient re-renders by providing clear, reusable approaches to local state management in React applications.
Core Features & Use Cases
- Typed stores: TypeScript examples for counters, todos, user and settings stores.
- Persistence & Middleware: Guidance for using persist, immer, and devtools middleware to maintain state across sessions and enable safe mutations and debugging.
- Selectors & Performance: Techniques to select specific fields or shallowly pick multiple fields to avoid unnecessary re-renders.
- Slices & Composition: Patterns for composing independent slices (user, cart, etc.) into a single unified store.
- Async and External Usage: Examples for async actions (fetching) and accessing or subscribing to the store outside React components.
Quick Start
Create a typed counter store with increment, decrement, and reset methods, enable persistence for settings, and demonstrate a selector-based React component that reads only the count.
