How do I migrate my Next.js app from version 15 to 16?▼

Next.js 16 migration requires updating async route parameters to use await, converting middleware.ts to proxy.ts, and adding explicit default.js files in parallel routes. This Skill automates these breaking changes and prevents common mistakes during the upgrade process.

What is the proxy.ts migration and why is it required in Next.js 16?▼

The proxy.ts migration replaces the older middleware.ts pattern in Next.js 16. This Skill handles the conversion automatically, including updating route handlers and ensuring compatibility across Vercel, Cloudflare Workers, AWS, and self-hosted deployments.

What are Next.js 16 cache components and how do I use them?▼

Next.js 16 introduces the 'use cache' directive and updated caching APIs like revalidateTag, updateTag, and refresh for granular cache control. This Skill implements these patterns and shows how to configure caching for server components and actions.

Can I use this for projects deployed on Cloudflare Workers or AWS?▼
