State Management in 2025: Beyond Redux

State management has undergone a significant evolution in the React ecosystem. While Redux dominated the landscape for years, a new generation of libraries has emerged, offering more streamlined approaches with less boilerplate and better performance characteristics.

The Redux Era

Redux established itself as the de facto state management solution for React applications by providing:

• A single source of truth (the store)
• Predictable state updates through reducers
• Time-travel debugging and powerful dev tools
• Middleware for handling side effects

However, Redux also became known for:

• Significant boilerplate code
• Steep learning curve with concepts like actions, reducers, and thunks
• Verbose updates for nested state
• Performance challenges in large applications

Modern State Management Approaches

TanStack Query (React Query): Server State Management

TanStack Query has redefined how we think about server state in React applications. It recognizes that much of what we place in global state is actually cached server data.

Key Features:

      const { data, isLoading, error } = useQuery({
        queryKey: ['todos'],
        queryFn: fetchTodos,
        staleTime: 60000,
        cacheTime: 900000,
      });

• Automatic caching and refetching
• Built-in loading and error states
• Background updates and data synchronization
• Pagination and infinite scroll support
• Optimistic updates
• Automatic garbage collection

TanStack Query handles the complex lifecycle of server data, including caching, background refetching, and invalidation, drastically reducing the need for manual state management code.

Zustand: Simplified Global State

Zustand offers a minimalist approach to global state management without the Redux boilerplate:

      import create from 'zustand';

      const useStore = create((set) => ({
        bears: 0,
        increasePopulation: () => set((state) => ({ bears: state.bears + 1 })),
        removeAllBears: () => set({ bears: 0 }),
      }));

Key Features:

• Minimal boilerplate
• No providers needed at the application root
• Compatible with React's Concurrent Mode
• Middleware support (similar to Redux)
• Devtools integration

Zustand simplifies global state by reducing the conceptual overhead while maintaining the capability to handle complex state scenarios.

Jotai: Atomic State Management

Jotai takes inspiration from Recoil and offers atom-based state management:

      import { atom, useAtom } from 'jotai';

      const countAtom = atom(0);
      const doubleAtom = atom((get) => get(countAtom) * 2);

      function Counter() {
        const [count, setCount] = useAtom(countAtom);
        const [doubleCount] = useAtom(doubleAtom);
        
        return (
          <div>
            <h1>{count}</h1>
            <h2>Double: {doubleCount}</h2>
            <button onClick={() => setCount(c => c + 1)}>+1</button>
          </div>
        );
      }

Key Features:

• Atom-based state with derived state
• No context providers needed
• Great for fine-grained state updates
• Works well with React Suspense
• Minimal re-renders

Jotai excels in scenarios requiring fine-grained reactivity with minimal re-renders, making it particularly useful for performance-critical applications.

How to Choose Between Modern Options

When evaluating state management solutions, consider these questions:

1. Is the data from a server?

• If yes, TanStack Query should be your first consideration

2. How complex is your state?

• Simple UI state: React's useState or useReducer
• Moderate global state: Zustand
• Complex interdependent state: Jotai or Recoil

3. Performance requirements?

• Fine-grained updates with minimal re-renders: Jotai
• Simpler global state with good performance: Zustand
• Server data with caching needs: TanStack Query

Migrating from Redux

Many teams are successfully migrating from Redux to these newer solutions:

1. Incremental approach

• Move server state to TanStack Query first
• Gradually replace Redux slices with Zustand stores or Jotai atoms
• Use adapters/middlewares to bridge during transition

2. Benefits of migration

• Reduced boilerplate
• Better performance
• More maintainable codebase
• Improved developer experience

The Future of State Management

Looking ahead, we can expect:

• Continued emphasis on atomic updates for performance
• Better integration with React's Concurrent Features
• More specialized tools separating UI state from server state
• Improved developer experiences with better debugging tools

Conclusion

While Redux served the React community well for many years, the new generation of state management libraries offers more targeted solutions with less boilerplate and better performance characteristics. By understanding the strengths of each approach, developers can choose the right tool for their specific requirements, often combining multiple libraries for different aspects of state management.

The best state management approach is often a combination of:

• TanStack Query for server state
• A lightweight solution like Zustand or Jotai for global UI state
• React's built-in state for component-local concerns

This separation of concerns leads to more maintainable, performant applications with clearer data flow and fewer bugs.
