Next.js Best Practices

Apply these rules when writing or reviewing Next.js code.

Note: Next.js 16 renamed middleware.ts to proxy.ts. Verify proxy.ts support in your version; middleware.ts remains the stable API.

File Conventions

See file-conventions.md for:

• Project structure and special files
• Route segments (dynamic, catch-all, groups)
• Parallel and intercepting routes
• Middleware rename in v16 (middleware → proxy)
