currentUser()

The currentUser helper returns the Backend 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/{user_id} endpoint.
• counts towards the Backend API Request Rate Limit.

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

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

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

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