Add Documentation for Using Server Actions with react-hook-form

[sadik-malik]

Many developers are starting to adopt Server Actions in Next.js App Router and Astro, but there is currently no official guidance on how to integrate this approach with react-hook-form.

As an open-source user of this library, I’ve found it challenging to find reliable patterns for combining react-hook-form with the new server-side form submission approach.

Describe the solution you'd like

I’d love to see an official guide or example on how to:

• Use react-hook-form with a <form action={serverAction}> pattern.
• Handle validation (client + server) using libraries like zod.
• Return and display errors on the client.
• Use server responses for success messages or revalidation.

Additional context

This kind of guide would be very helpful for those using the Server Actions, particularly with Next.js or Astro where Server Actions are becoming more stable and widely adopted.

If maintainers are open to this, it could be a valuable addition to the docs, even under an “experimental” section.

I completely agree we use react-hook-form + Zod with Next.js Server Actions for onboarding and profile forms, and it's been difficult to find a simple, type-safe integration strategy. An official example of <form action={serverAction}> use, client-server validation, and error handling would be quite helpful. As Server Actions become common in Next.js and Astro, it would greatly facilitate the adoption of react-hook-form.
