The big idea
Server Actions in Next.js let you write a function with `'use server'` and call it from a form — no fetch, no API route. AI explains when to use them, how to pass FormData, and how to handle errors.
Some examples
- Ask AI: 'Convert this fetch-to-API-route form into a Server Action.'
- AI shows you how to revalidate a cache tag after a mutation.
- AI catches when you forget `'use server'` at the top.
- AI writes a useFormState wrapper for inline error messages.
Try it!
Build a one-field 'add a todo' form using a Server Action. Have AI add input validation with Zod.
