Next.js App Router
Builds production-grade Next.js 16 applications using the App Router, React 19.2 Server Components, Server Actions, and modern caching patterns.
Equips Claude Code with expert-level knowledge of Next.js 16 and React 19.2, streamlining the implementation of App Router architectures, Server Actions, and Cache Components with the 'use cache' directive. It actively prevents common upgrade pitfalls such as unawaited async route parameters, legacy middleware usage in favor of proxy.ts, and missing parallel route default templates, while providing battle-tested patterns for streaming SSR, Route Handlers, and performance optimization.
