zustand-store

State management with Zustand involves creating a store file with typed state and actions, exporting custom hooks, and using them in components. Define your store using `create()`, add actions for state updates, and export hooks like `useStore` for component access. Zustand automatically handles immutability and re-render optimization.

Yes, Zustand's persist middleware saves store state to localStorage automatically. Configure it when creating your store by wrapping your state with `persist()`, specifying a storage name. State persists across page reloads and syncs seamlessly with your component subscriptions.

Organize large stores using slices—split state and actions into focused modules, then combine them into a single store. Create domain-specific stores (todoStore, uiStore) rather than one monolithic store. Export barrel files and typed hooks from each domain for clean, modular access throughout your application.

Selectors let components subscribe to specific state slices instead of the entire store, preventing unnecessary re-renders when unrelated state changes. Use selector functions to extract only the data your component needs. Combined with TypeScript typing, this pattern reduces render cycles and improves app performance.

Yes, Zustand fully supports TypeScript with type-safe state and actions. Immer integration enables draft-based mutations that feel intuitive while maintaining immutability. Configure Immer middleware in your store to use draft state inside actions, automatically producing immutable updates.

Zustand supports async actions through standard JavaScript async/await within action functions. Middleware composition lets you stack multiple middleware (persist, devtools, Immer) for advanced patterns like versioned migrations. Chain middlewares during store creation to build sophisticated state workflows.
