Zustand best practices

Use when using Zustand for client-side global or shared state.

Store shape

• Keep stores small and focused by domain or feature.
• Split large global state into multiple stores instead of one giant store.

Updates and API

• Prefer actions inside the store for state updates (clear entry points).
• Keep business rules in store actions, not scattered across components.

Selectors and renders

• Use selectors to avoid unnecessary re-renders.
• Use shallow comparison when selecting multiple fields as an object.
