React UI patterns for loading states, error handling, and async data in components. \n \n Three core patterns: show loading indicators only when data is absent, always surface errors to users, and disable buttons during async operations to prevent duplicate submissions \n Includes decision trees and component examples for skeleton vs. spinner selection, error state hierarchy (inline, toast, banner, full screen), and empty state requirements for all collections \n Covers form submission workflows

Build smooth 60fps animations combining Reanimated 3, Gesture Handler, and layout transitions. \n \n Master Reanimated's shared values, animated styles, and timing functions (withSpring, withTiming, withDecay) for declarative animations \n Handle complex gestures like pan, pinch, and rotation using Gesture Handler, then synchronize them with animations via shared values \n Implement entering/exiting animations and layout transitions using FadeIn, FadeOut, and Layout.springify() for dynamic lists

Type-safe React 18–19 patterns with compile-time guarantees for components, hooks, events, and routing. \n \n Covers React 19 breaking changes: ref as prop (no forwardRef), useActionState for forms, use() for promise unwrapping, and Server Components with async data fetching \n Specific event typing (MouseEvent, ChangeEvent, KeyboardEvent, etc.) and discriminated unions for variant props eliminate runtime surprises \n Generic component patterns with constrained types for reusable Tables, Lists,

Modern React 19 patterns for Server Components, Actions, concurrent features, and TypeScript development. \n \n Covers core hooks (useState, useEffect, useRef, useMemo, useCallback) with TypeScript typing and custom hook extraction patterns \n Includes React 19 features: use() hook, useOptimistic, useFormStatus, useFormState, Server Actions, and Server Components with mixed architecture examples \n React Compiler automatic optimization eliminates manual memoization; includes setup, configuration

Comprehensive performance optimization and best practices for React applications, designed for AI agents and LLMs working with React code.
