Next.js › State Management in Next.js Apps

When would you reach for a dedicated state management library, like Zustand or Redux, instead of just using React Context?

Answer

You typically reach for a dedicated library when your application's shared state becomes complex, needs to be updated frequently from many different places, or requires more advanced features like middleware, persistence, or fine grained performance optimizations that plain React Context does not handle as efficiently at a large scale.

import { create } from 'zustand';

export const useCartStore = create((set) => ({
  items: [],
  addItem: (item) => set((state) => ({ items: [...state.items, item] }))
}));

Real-world example A complex dashboard application with many interconnected pieces of shared state adopts Zustand to keep state updates organized and performant, avoiding the unnecessary re-renders that a large context object might cause.
