const count = useStore((state) => state.count) const increase = useStore((state) => state.increase) const useStore = create((set) => ({ user: null, fetchUser: async (id) => { const response = await fetch(`/api/user/${id}`) const userData = await response.json() set({ user: userData }) }, })) 6. Middleware (Persistence) import { persist } from 'zustand/middleware' const useStore = create( persist( (set) => ({ count: 0, increase: () => set((state) => ({ count: state.count + 1 })) }), { name: 'counter-storage' } // auto-saves to localStorage ) ) 7. TypeScript Support interface StoreState { count: number increase: () => void } const useStore = create<StoreState>((set) => ({ count: 0, increase: () => set((state) => ({ count: state.count + 1 })), })) If you meant something else by "Zust2help" (maybe a typo for a different library, tool, or internal project name), please clarify and I’ll give you a targeted answer.
Here’s a concise, solid, practical guide to using Zustand in a React project: npm install zustand 2. Create a Store // store.js import { create } from 'zustand' const useStore = create((set) => ({ count: 0, increase: () => set((state) => ({ count: state.count + 1 })), decrease: () => set((state) => ({ count: state.count - 1 })), reset: () => set({ count: 0 }), })) 3. Use in Components function Counter() { const { count, increase, decrease, reset } = useStore() return ( <div> <span>{count}</span> <button onClick={increase}>+</button> <button onClick={decrease}>-</button> <button onClick={reset}>Reset</button> </div> ) } 4. Selectors for Performance Only re-render when a specific piece of state changes:
