This Skill helps you migrate and stabilize Next.js 16 apps by mastering async route parameters, proxy-based middleware, and Cache Components.
High-intent search queries and answers about installing and using this skill.
Migrate from Next.js middleware by renaming middleware.ts to proxy.ts and updating the function name to proxy. This proxy migration enables Node.js runtime proxies with explicit network boundaries for predictable server rendering in Next.js 16.
Async route parameters in Next.js 16 app router require awaiting params, searchParams, cookies(), and headers() in route handlers. This pattern ensures predictable server rendering by resolving dynamic data before rendering server components.
Use Cache Components by adding the "use cache" directive to cache components, functions, and pages. Leverage partial prerendering (PPR) and cache APIs like revalidateTag, updateTag, and refresh to control caching lifecycles for predictable server rendering.
Parallel routes break navigation when missing a default.tsx file for a parallel slot. Create default.tsx or default.ts for every parallel route slot to ensure graceful navigation and prevent rendering errors across server/client boundaries.
The best way to upgrade Next.js 15 to 16 is running the codemod npx @next/codemod@canary upgrade latest. This codemod-driven migration handles async parameters, proxy migrations, and Cache Components automatically for predictable server rendering.
Yes, Next.js 16 proxy.ts supports Node.js runtime features for explicit network boundaries. Migrate from middleware.ts to proxy.ts to leverage Node.js runtime proxies and apply proxy.ts templates for predictable server rendering.
