SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill provides a robust pattern for handling data mutations in Next.js applications, ensuring security, data integrity, and a seamless user experience.

Core Features & Use Cases

  • Secure Mutations: Implements the 'use server' directive for server-side data operations.
  • Input Validation: Utilizes Zod for strict validation of incoming data.
  • Authentication & Authorization: Integrates with Supabase for user authentication and staff profile checks.
  • Cache Invalidation: Ensures UI consistency by revalidating affected paths after mutations.
  • Use Case: When a user submits a new transaction in the operator dashboard, this pattern ensures the data is validated, saved securely to the database, and the relevant parts of the UI are updated automatically.

Quick Start

Use the server-action skill to insert a new record into the 'table_name' table with 'value1' and 'value2'.

Frequently Asked Questions about server-action

FAQPage Schema
How do I handle secure data mutations in Next.js using Server Actions?▼

Next.js Server Actions handle secure data mutations by running server-side functions marked with 'use server'. This pattern validates inputs with Zod, authenticates users via Supabase, and executes database operations safely.

What is the best way to validate input data in Next.js Server Actions?▼

The best way to validate input data in Next.js Server Actions is using Zod schemas. This ensures strict type checking and validation of incoming data before any database mutation or Supabase authentication logic is executed.

How do I revalidate paths and update the UI after a Supabase database mutation?▼

To revalidate paths after a Supabase database mutation, call Next.js path revalidation functions at the end of your Server Action. This triggers cache invalidation and automatically updates the relevant UI components.

Can I use Supabase authentication to check staff profiles and branch access in Next.js?▼

Yes, you can use Supabase authentication within Server Actions to verify user identities and retrieve staff profiles. This allows you to securely enforce branch access controls before authorizing any data mutations.

When do I need to use Zod validation with Server Actions for data mutations?▼

You need to use Zod validation with Server Actions whenever accepting user input for data mutations. It prevents invalid or malicious data from reaching your Supabase database by enforcing strict schema constraints.
