Nextjs Production · eponymousbearer bundle Production-grade engineering standards for Next.js (App Router), React, and TypeScript. Use this whenever writing, reviewing, refactoring, scaffolding, or debugging any Next.js, React, or TypeScript code — components, Server/Client Components, route handlers, Server Actions, data fetching, forms, auth, or API routes — even when the user does not explicitly say "production". Apply it before claiming a feature is "done", and especially when the user asks to "build", "add a feature", "fix", or "ship". The goal is code that survives real users, not code that merely runs in a demo.
