- Serve the app over HTTPS so the httpOnly authentication cookies remain secure, matching the expectations codified in
lib/auth-server.ts. - Update any environment variables (such as
NEXT_PUBLIC_SITE_URL, if you introduce one) in both the deployment platform and the App Router metadata for accurate links. - Coordinate DNS records (A, CNAME, or ALIAS) with the guidance from your platform—Vercel, for example, exposes automated certificate management that works well with the Starter Kit.
