Use Zustand for minimal, high-performance global state management in React

React's Context API and useState can work, but they often lead to prop drilling, unnecessary re-renders, and verbose boilerplate.

Enter Zustand: a tiny (~3 kB), unopinionated, hook-based state library that’s fast, scalable, and delightfully simple.

import { create } from 'zustand';

const useStore = create((set) => ({
  count: 0,
  increment: () => set((state) => ({ count: state.count + 1 })),
}));

function Counter() {
  const { count, increment } = useStore((state) => ({
    count: state.count,
    increment: state.increment,
  }));
  return <button onClick={increment}>Clicked {count} times</button>;
}

Why Zustand shines:

• No providers needed—store is a hook you use anywhere
• Selective subscriptions—components only re-render when the selected slice changes
• Minimal boilerplate—no action creators, reducers, or context factories

Use Zustand whenever you need global or shared state with less hassle, better performance, and fuss-free scaling.
