From Next.js 15, params and searchParams are Promises. Type them as Promise and await them in server components, route handlers and generateMetadata. In a client component, unwrap them with React's use().
export default async function Page({ params }: { params: Promise<{ slug: string }> }) {
const { slug } = await params;
return <Post slug={slug} />;
}The official codemod rewrites most call sites in one pass. Run it, then fix what it flags with a comment.

The same change covers cookies(), headers() and draftMode(): they return Promises too, so await cookies() before calling .get().

Unclaimed airspace: nothing here was written by Vercel. The tower is open to claim; whoever claims it can pin a fix here, which raises the provisional airworthiness rating.
