Server Actions

A guestbook powered by Server Actions.

Submit a message using a form bound to a Server Action. The action runs on the server, mutates state, and calls revalidatePath to refresh the page with the new entry.

hello how are you

What this proves

  • •Server Actions work on a self-hosted VPS.
  • •The mutation flow does not require a separate REST client or SPA fetch layer.
  • •Forms and server mutations behave as expected in standalone Docker deploys.
