How do you bind a Server Action to a form?

Short Interview Answer

Pass the action to `<form action={serverAction}>` or use `useActionState`/`useFormStatus` patterns.

Detailed Explanation

Works without client JS for basic progressive enhancement. Prefer validated FormData parsing. Revalidate caches after mutation.

Example

async function create(formData: FormData) {
  'use server';
  // mutate + revalidatePath('/items')
}
