State Management in 2025: Beyond Redux and Context

The state management conversation has changed. Redux is no longer the default answer, Context is understood to have real performance limits, and a new generation of tools has made it genuinely easier to manage both client and server state. Here's how I think about the decision in 2025.

The Core Distinction: Server vs. Client State

The most important architectural decision is separating server state from client state. Server state — data that lives on a server and needs to be fetched, cached, and synchronized — should almost always be handled by a dedicated tool like TanStack Query or SWR. Client state — ephemeral UI state that does not persist — can often live in component-local state or Zustand.

When Zustand Wins

Zustand wins when you need global client state with minimal boilerplate. Its store model is simpler than Redux and more explicit than Context, and it doesn't require a provider wrapper. For things like user preferences, shopping cart state, or UI mode toggles, Zustand is often the simplest correct answer.

import { create } from 'zustand';

interface CartStore {
  items: CartItem[];
  add: (item: CartItem) => void;
  remove: (id: string) => void;
}

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

When Context Is Actually Fine

Context is fine for low-frequency updates to large subtrees — things like theme, locale, or user authentication. The performance concerns with Context are real, but they only materialize when the context value changes frequently and there are many expensive components subscribed to it.
