What problem does it solve?

Server Actions streamline handling server-side form submissions, data mutations, and post-mutation cache updates in Next.js App Router, removing boilerplate for sending form data to the server and keeping rendered pages in sync.

Core Features & Use Cases

  • Server-side Mutations: Define async actions with the use server directive to perform CRUD operations from forms or programmatic calls.
  • Robust Form Handling: Integrate useFormState and useFormStatus for validation feedback, loading states, and returning structured error/success state to the client.
  • Cache Revalidation & Redirects: Use revalidatePath, revalidateTag, and redirect to update server-rendered pages after mutations.
  • Optimistic UI & Transactions: Support optimistic updates, bound actions, file uploads, multi-step transactions, and safe error handling with examples for common mutation patterns.
  • Use Case: Implement a signup form that validates input with Zod, creates a user record on the server, revalidates relevant pages, and returns structured form state to the client.

Quick Start

Use the server-actions skill to create a 'use server' action that validates form input, saves a new post, revalidates /posts, and returns success or field errors.

FAQPage Schema
How do I handle form submissions and data mutations in Next.js App Router?▼

Next.js Server Actions handle form submissions and data mutations by using the 'use server' directive to perform CRUD operations and return structured state to the client without manual API boilerplate.

How do I use useFormState and useFormStatus for form validation feedback in Next.js?▼

useFormState and useFormStatus manage form validation feedback and loading states in Next.js by capturing structured error or success states returned from server actions and reflecting them in the client UI.

How do I revalidate cached data and redirect after a server mutation in Next.js?▼

Revalidate cached data and redirect after Next.js server mutations by calling revalidatePath or revalidateTag to sync server-rendered pages, followed by the redirect API to navigate the user.

Can I validate server action input with Zod and return field errors to the client?▼

Yes, server actions can validate form input with Zod to ensure data integrity, returning specific field errors to the client via useFormState to display validation feedback directly under inputs.

What is the best way to implement optimistic UI updates during Next.js server mutations?▼

Implement optimistic UI updates during Next.js server mutations by applying optimistic update patterns within your server actions to instantly reflect expected changes before the server response completes.

Do Next.js server actions support multi-step transactions and file uploads?▼

Next.js server actions support multi-step transactions, file uploads, and bound action patterns, enabling complex mutation workflows with safe error handling for common data operations.
