Accessing Store Outside React // In a utility function or plain JS module import useStore from './store' // Get current state const currentState = useStore.getState()

// Example: Only persist on client side const useStore = create( persist( (set) => ( /* state */ ), name: 'my-store', getStorage: () => if (typeof window !== 'undefined') return localStorage return dummyStorage , ) ) 1. Splitting Stores Avoid one giant store. Split by domain. Split by domain

const useStore = create((set) => ( count: 0, increment: () => set((state) => ( count: state.count + 1 )), decrement: () => set((state) => ( count: state.count - 1 )), )) Using Redux DevTools Wrap your store with devtools() : ( count: 0

Use persist with a skipHydration option or conditionally access storage.

// Bad — re-renders on any state change const count, increment, user = useStore() // Good — re-renders only when count changes const count = useStore((state) => state.count) const increment = useStore((state) => state.increment) Issue: Event handlers or useEffect closures capture old state.
