Core React patterns for component design, state management, and optimization.

Modern React patterns and best practices for production applications. \n \n Covers component design principles, hook extraction patterns, and state management selection across complexity levels from simple useState to global stores like Zustand and Redux Toolkit \n Includes React 19 patterns with new hooks (useActionState, useOptimistic, use) and compiler benefits for automatic memoization \n Provides composition patterns including compound components, render props vs hooks trade-offs, and highe

React and Next.js patterns for component composition, state management, performance, and accessibility. \n \n Covers component patterns including composition, compound components, and render props, plus custom hooks for state, data fetching, and debouncing \n Includes performance optimization techniques: memoization, code splitting with lazy loading, and list virtualization for large datasets \n Provides form handling with validation, error boundaries, and animation patterns using Framer Motion

Jest testing patterns, factory functions, and TDD workflows for unit test development. \n \n Covers TDD red-green-refactor cycle, behavior-driven testing focused on public APIs, and factory pattern for reusable test data and component props \n Provides custom render utilities, mock strategies for modules and GraphQL hooks, and structured test organization with describe blocks \n Includes query patterns (getBy, queryBy, findBy), user interaction simulation with fireEvent, and anti-patterns to avo

FastAPI async patterns for building high-performance, concurrent APIs with optimal resource usage. \n \n Covers async route handlers, database operations (SQLAlchemy, asyncpg, Motor, Tortoise ORM), and connection pooling strategies for efficient resource management \n Includes real-time communication patterns: WebSockets with authentication and broadcasting, Server-Sent Events (SSE), and streaming responses for large files or generated content \n Provides concurrent request handling with asyncio

Performance optimization patterns for Mapbox GL JS applications, prioritized by user impact. \n \n Eliminate initialization waterfalls by loading map data in parallel with map initialization, and set precise viewport to avoid redundant tile fetches \n Use symbol layers for 100+ markers (GPU-accelerated) and clustering for 10,000+ features; avoid HTML markers at scale \n Choose GeoJSON for datasets under 5 MB, vector tiles for 20+ MB; implement viewport-based loading to reduce bandwidth \n Always
