# Actions

> Mutations for a Next.js 16 site — 'use server' actions validated with zod v4 (the { error } param, message is deprecated), useActionState form wiring per the stable React 19 signature, errors returned as data instead of thrown, optimistic UI with useOptimistic for low-stakes mutations, and a mandatory progressive-enhancement test (the form must work with JavaScript disabled). Invoke during the backend phase when wiring any form submit or write — contact form, newsletter signup, CRUD, settings save, like/toggle — when a form throws opaque errors instead of showing field messages, or when a mutation goes through a client fetch to an API route. Trigger phrases — "wire up the form", "handle the submit", "server action", "form validation", "contact form backend", "optimistic update", "the form errors are ugly".
