State Management Patterns

Redux Pattern


// Action Types
const ADD_TODO = 'ADD_TODO';

// Action Creator
const addTodo = (text) => ({
    type: ADD_TODO,
    payload: { text }
});

// Reducer
const todoReducer = (state = [], action) => {
    switch (action.type) {
        case ADD_TODO:
            return [...state, action.payload];
        default:
            return state;
    }
};

// Store Usage
store.dispatch(addTodo('Learn Redux'));

Context API Pattern


// Create Context
const TodoContext = React.createContext();

// Provider Component
const TodoProvider = ({ children }) => {
    const [todos, setTodos] = useState([]);
    
    const addTodo = (text) => {
        setTodos([...todos, { text }]);
    };
    
    return (
        
            {children}
        
    );
};

Performance Optimization

Caching Strategies


// Redis Caching Example
const getUser = async (userId) => {
    // Try cache first
    const cachedUser = await redis.get(`user:${userId}`);
    if (cachedUser) return JSON.parse(cachedUser);
    
    // Database query if cache miss
    const user = await db.users.findById(userId);
    await redis.set(`user:${userId}`, JSON.stringify(user));
    return user;
};
