Cart Management Skill
Patterns for React cart state: duplicate prevention, persistence, context design.
Duplicate Prevention
Track product IDs in CartContext (separate state or derived from cartItems) Check productIdsInCart.includes(item.id) before add Centralize logic in context, not in ProductCard or child components
Persistence (localStorage)
Initialize cart state from localStorage.getItem('cart') on mount Persist on every add/remove: localStorage.setItem('cart', JSON.stringify(cartItems)) Sync productIdsInCart if used: localStorage.setItem('cart_ids', JSON.stringify(ids)) Prevents duplicates across sessions (refresh, new tab)
CartContext Pattern
const addToCart = (item: CartItem) => { if (!productIdsInCart.includes(item.id)) { setCartItems(prev => [...prev, item]); setProductIdsInCart(prev => [...prev, item.id]); localStorage.setItem('cart', JSON.stringify([...cartItems, item])); } };
Anti-Patterns
Don't add to cart in useEffect on ProductCard mount (causes duplicates) Don't duplicate logic in multiple components β use context Add backend validation as fallback for data integrity
Quantity Updates
For same-product quantity: use cartItems.map() to update item.quantity, don't create duplicate entries.
Category context
Agent frameworks, memory systems, reasoning layers, and model-native orchestration.
