State Management Patterns

Learn best practices and patterns for state management in React applications

80 minBy Priygop TeamLast updated: Feb 2026

When to Use Each Solution

  • useState: Local component state
  • useReducer: Complex local state logic
  • Context API: Shared state across components
  • Redux Toolkit: Large applications with complex state
  • Zustand: Simple global state management
  • Server State: Use React Query or SWR

State Management Best Practices

Example
// 1. Keep state as local as possible
function UserProfile({ user }) {
    const [isEditing, setIsEditing] = useState(false);
    const [localUser, setLocalUser] = useState(user);
    
    // Local state for UI interactions
    const handleEdit = () => setIsEditing(true);
    const handleCancel = () => {
        setIsEditing(false);
        setLocalUser(user); // Reset to original
    };
    
    return (
        <div>
            {isEditing ? (
                <EditForm user={localUser} onSave={handleSave} onCancel={handleCancel} />
            ) : (
                <UserDisplay user={user} onEdit={handleEdit} />
            )}
        </div>
    );
}

// 2. Use custom hooks for state logic
function useUserManagement() {
    const [users, setUsers] = useState([]);
    const [loading, setLoading] = useState(false);
    const [error, setError] = useState(null);
    
    const fetchUsers = async () => {
        setLoading(true);
        try {
            const response = await fetch('/api/users');
            const data = await response.json();
            setUsers(data);
        } catch (err) {
            setError(err.message);
        } finally {
            setLoading(false);
        }
    };
    
    const addUser = async (user) => {
        try {
            const response = await fetch('/api/users', {
                method: 'POST',
                headers: { 'Content-Type': 'application/json' },
                body: JSON.stringify(user)
            });
            const newUser = await response.json();
            setUsers(prev => [...prev, newUser]);
        } catch (err) {
            setError(err.message);
        }
    };
    
    return { users, loading, error, fetchUsers, addUser };
}

// 3. Combine multiple state management solutions
function App() {
    return (
        <Provider store={store}>
            <ThemeProvider>
                <UserProvider>
                    <Router>
                        <Routes>
                            <Route path="/" element={<Home />} />
                            <Route path="/dashboard" element={<Dashboard />} />
                        </Routes>
                    </Router>
                </UserProvider>
            </ThemeProvider>
        </Provider>
    );
}
