currentUser()

The currentUser helper returns the Backend API User object of the currently active user. It can be used in Server Components, Route Handlers, and Server Actions.

Under the hood, this helper:

• calls fetch(), so it is automatically deduped per request.
• uses the GET /v1/users/me endpoint, so it is subject to rate limits.

import { currentUser } from '@clerk/nextjs';

export default async function Page() {
  const user = await currentUser();

  if (!user) return <div>Not signed in</div>;

  return <div>Hello {user?.firstName}</div>;
}
