background

State management in React has evolved significantly over the years. With new libraries and patterns emerging, it's essential to understand the landscape and choose the right solution for your project. Having worked with various state management approaches at Dentira and Dentira Labs, I've learned that there's no one-size-fits-all solution—context matters.

The State Management Landscape in 2025

The React ecosystem now offers more choices than ever before. While Redux remains popular, newer solutions like Zustand, Jotai, and React Query have gained significant traction for specific use cases.

Why So Many Options?

Different state management solutions solve different problems:

Global state vs Server state vs Local state
Performance requirements
Developer experience preferences
Bundle size constraints
Team familiarity

1. Zustand - Lightweight and Flexible

Zustand has become my go-to choice for many projects. It's minimal, performant, and incredibly easy to use.

Why Zustand?

import create from 'zustand';

interface StoreState {
  count: number;
  user: User | null;
  increment: () => void;
  setUser: (user: User) => void;
}

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

Advantages:

Minimal boilerplate
No providers needed
Excellent TypeScript support
Small bundle size (~1KB)
Easy to test

When to use:

Medium-scale applications
When you want simplicity without Redux complexity
Team prefers functional programming patterns

Real-World Example

At Dentira Labs, we used Zustand for managing scanner configurations:

interface ScannerStore {
  activeScanner: ScannerType | null;
  scannerConfig: ScannerConfig;
  setActiveScanner: (scanner: ScannerType) => void;
  updateConfig: (config: Partial<ScannerConfig>) => void;
}

export const useScannerStore = create<ScannerStore>((set) => ({
  activeScanner: null,
  scannerConfig: defaultConfig,
  setActiveScanner: (scanner) => set({ activeScanner: scanner }),
  updateConfig: (config) =>
    set((state) => ({
      scannerConfig: { ...state.scannerConfig, ...config },
    })),
}));

2. Redux Toolkit - Still Going Strong

Redux Toolkit (RTK) has modernized Redux, making it more approachable while maintaining its power.

Modern Redux with RTK

import { createSlice, configureStore } from '@reduxjs/toolkit';

const cartSlice = createSlice({
  name: 'cart',
  initialState: { items: [] },
  reducers: {
    addItem: (state, action) => {
      state.items.push(action.payload);
    },
  },
});

export const store = configureStore({
  reducer: {
    cart: cartSlice.reducer,
  },
});

Advantages:

Time-travel debugging
Extensive ecosystem
Predictable state updates
Great for large applications
Excellent DevTools

When to use:

Large-scale applications
Complex state logic
Team already familiar with Redux
Need middleware for async operations

3. React Query / TanStack Query - Server State

React Query revolutionized how we handle server state. It's not a replacement for client state management but complements it perfectly.

Handling Server State

import { useQuery, useMutation, useQueryClient } from '@tanstack/react-query';

function useProducts() {
  return useQuery({
    queryKey: ['products'],
    queryFn: fetchProducts,
    staleTime: 5 * 60 * 1000, // 5 minutes
  });
}

function useAddProduct() {
  const queryClient = useQueryClient();
  
  return useMutation({
    mutationFn: createProduct,
    onSuccess: () => {
      queryClient.invalidateQueries({ queryKey: ['products'] });
    },
  });
}

Advantages:

Automatic caching and synchronization
Background refetching
Optimistic updates
Request deduplication
Error and loading states built-in

When to use:

Any application fetching data from APIs
Real-time data synchronization
Complex caching requirements

4. Context API - Built-in Solution

React's Context API remains useful for certain scenarios, though it has limitations.

When Context Makes Sense

const ThemeContext = createContext<ThemeContextType>({
  theme: 'light',
  toggleTheme: () => {},
});

export function ThemeProvider({ children }: Props) {
  const [theme, setTheme] = useState<'light' | 'dark'>('light');
  
  const value = useMemo(
    () => ({
      theme,
      toggleTheme: () => setTheme((t) => (t === 'light' ? 'dark' : 'light')),
    }),
    [theme]
  );
  
  return (
    <ThemeContext.Provider value={value}>
      {children}
    </ThemeContext.Provider>
  );
}

Advantages:

Built into React
No additional dependencies
Simple for small apps

Limitations:

Performance issues with frequent updates
Not ideal for frequently changing state
Can cause unnecessary re-renders

When to use:

Theme/UI preferences
User authentication context
Simple, rarely-changing values
Small applications

5. Jotai - Atomic State Management

Jotai takes an atomic approach to state management, breaking state into small, independent atoms.

Atomic Pattern

import { atom, useAtom } from 'jotai';

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

function Counter() {
  const [count, setCount] = useAtom(countAtom);
  const [doubled] = useAtom(doubledAtom);
  
  return (
    <div>
      <p>Count: {count}</p>
      <p>Doubled: {doubled}</p>
      <button onClick={() => setCount((c) => c + 1)}>Increment</button>
    </div>
  );
}

Advantages:

Fine-grained reactivity
Automatic code splitting
Composition-friendly
Small bundle size

When to use:

Need granular updates
Want automatic code splitting
Complex derived state
Preference for atomic patterns

Choosing the Right Solution

Decision Framework

Application Size:
- Small: Context API or Zustand
- Medium: Zustand or Redux Toolkit
- Large: Redux Toolkit
State Type:
- Client state: Zustand, Redux, or Context
- Server state: React Query/TanStack Query
- Mixed: Combine solutions
Team Experience:
- Redux experience: Redux Toolkit
- Prefer simplicity: Zustand
- New to React: Context API
Performance Requirements:
- High performance needs: Zustand or Jotai
- Standard requirements: Most solutions work
DevTools Need:
- Critical debugging: Redux Toolkit
- Basic debugging: Most modern solutions

Best Practices for 2025

1. Separate Concerns

Don't use one solution for everything:

// ✅ Good: Separate server and client state
const { data: products } = useQuery(['products'], fetchProducts); // Server state
const cart = useCartStore(); // Client state

// ❌ Bad: Mixing everything in one store
const { products, cart, user } = useEverythingStore();

2. Start Simple

Begin with the simplest solution that works:

Start with Context API or useState
Move to Zustand if you need more
Consider Redux Toolkit for complex scenarios

3. Use TypeScript

Strong typing prevents bugs and improves DX:

// ✅ Typed store
interface AppStore {
  user: User | null;
  setUser: (user: User) => void;
}

// ❌ Untyped store
const useStore = create((set) => ({ ... }));

4. Optimize Re-renders

Use selectors to prevent unnecessary re-renders:

// ✅ Only re-renders when user.name changes
const userName = useStore((state) => state.user?.name);

// ❌ Re-renders on any store change
const { user } = useStore();

5. Keep State Close

Don't lift state too high. Keep state as local as possible:

// ✅ Local state for component-specific data
const [isOpen, setIsOpen] = useState(false);

// ✅ Global state for shared data
const user = useUserStore();

Migration Strategies

If you're working with legacy Redux code, consider these patterns:

Gradual Migration: Use both Redux and Zustand during transition
Slice-by-Slice: Migrate one feature at a time
Adapter Pattern: Create adapters to bridge old and new patterns

Future Trends

Looking ahead, I see these trends:

More Composition: Libraries that compose well together
Better DX: Improved developer experience with better tooling
Performance Focus: Solutions optimized for React 19+ features
Type Safety: Even stronger TypeScript integration

Final Thoughts

The state management landscape in 2025 offers excellent choices for every scenario. The key is understanding your requirements and choosing accordingly. Don't overcomplicate—start simple and scale up when needed.

At Dentira Labs, we've successfully used a combination of Zustand for client state and React Query for server state. This combination provides excellent developer experience while keeping our bundle size reasonable.

Remember: the best state management solution is the one that your team can use effectively and that solves your specific problems. Experiment, learn, and don't be afraid to try new approaches as they emerge.
