React Zustand State Management

What is Zustand State Management in React?

Zustand is a very small state library with no provider and no boilerplate. You create a store with a hook, and components subscribe to exactly the slice they select.

Zustand State Management example

import { create } from 'zustand';

export const useCart = create(set => ({
  items: [],
  add: item => set(s => ({ items: [...s.items, item] })),
  remove: id => set(s => ({ items: s.items.filter(i => i.id !== id) })),
  clear: () => set({ items: [] }),
}));

// component — subscribes only to the count
const count = useCart(s => s.items.length);
const add = useCart(s => s.add);

Key points to remember

• No Provider component is required anywhere in the tree.
• Selecting a narrow slice means only components that use it re-render.
• Middleware adds persistence to localStorage and Redux DevTools support.
