SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires next, zod.

What problem does it solve?

This Skill streamlines the communication between Next.js frontend and NestJS backend by generating Server Actions, eliminating the need for explicit API routes for mutations and ensuring consistent data validation and cache management.

Core Features & Use Cases

  • Thin Orchestration Layer: Creates Server Actions ('use server') that act as a minimal bridge, delegating business logic to the NestJS backend.
  • Integrated Cache Management: Utilizes revalidatePath and revalidateTag to automatically update Next.js's data cache after mutations, ensuring UI consistency.
  • Standardized Error Handling: Implements robust error handling for Zod validation, API responses, and network issues, providing user-friendly feedback.
  • Use Case: When a user submits a form to create a new club, use a Server Action to validate the input, call the backend API, and automatically revalidate the cache for the clubs list page, updating the UI without a full page refresh.

Quick Start

To create a new Server Action, define a Zod schema for input validation, implement the action function with 'use server', call your backend API, and use revalidatePath() to update the cache.

Frequently Asked Questions about Server Actions Generator

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I handle form submissions between Next.js frontend and NestJS backend?▼

Server Actions bridge your Next.js frontend to NestJS backend by wrapping API calls in `'use server'` functions. Define a Zod schema for input validation, call your backend endpoint, handle errors, and use `revalidatePath()` to refresh cached data after mutations, keeping your UI synchronized without manual refetching.

What's the best way to validate form inputs before sending to a backend API?▼

Use Zod schemas within Server Actions to validate inputs on the server before calling your NestJS API. This approach provides type safety, catches invalid data early, and delivers user-friendly error messages, eliminating the need for separate client and server validation layers.

How do I keep my Next.js cache in sync after backend mutations?▼

After a Server Action completes a mutation via your NestJS API, call `revalidatePath()` or `revalidateTag()` to invalidate and refresh the Next.js cache. This ensures your UI automatically reflects the latest data without full page reloads or manual state management.

Can I use Server Actions with a NestJS API instead of Next.js API routes?▼

Yes. Server Actions are designed for this pattern. They orchestrate calls to external backends like NestJS, eliminating the need for intermediate Next.js API routes while maintaining type safety, centralized validation via Zod, and automatic cache management through revalidation.

What error handling does a Server Action provide for backend API failures?▼

Server Actions handle Zod validation errors, API response errors, and network failures, returning structured error information to the UI. This standardized error handling lets you display user-friendly messages and retry logic without writing custom error translation layers.

Do I need useTransition for form handling with Server Actions?▼

useTransition is optional but recommended. It tracks Server Action execution state, letting you disable submit buttons, show loading indicators, and handle pending states in real time, improving user feedback during mutations without additional state management.
