SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Build secure server-side APIs in Next.js using Server Actions and API routes.

Core Features & Use Cases

Server Actions: handle mutations securely on the server with validation (Zod) and safe error handling.
API Routes & Route Handlers: expose endpoints for external services, webhooks, and data fetching.
Architectural Best Practices: guidance on server components, secrets management, and revalidation to ensure data consistency.

Quick Start

Use the backend-api skill to create a sample server action that processes a form submission and updates a resource via an API route.

FAQPage Schema

How do I build secure server-side APIs in Next.js using Server Actions?▼

To build secure server-side APIs in Next.js, use Server Actions for mutations and Route Handlers for external interfaces. Enforce server-side validation with Zod, manage server-bound secrets securely, and implement robust error handling with data revalidation.

When should I use Next.js Server Actions versus API Route Handlers?▼

Use Next.js Server Actions for secure server-side mutations like form submissions, and use API Route Handlers to expose endpoints for external services, webhooks, and data fetching. Both require server-side validation with Zod.

How do I validate mutations in Next.js App Router projects?▼

Validate mutations in Next.js App Router projects by enforcing server-side validation with Zod. Apply Zod schemas within your Server Actions to ensure data integrity before processing secure server-side mutations and safe error handling.

What is the best way to handle external webhooks in a Next.js application?▼

The best way to handle external webhooks in a Next.js application is by using Route Handlers. Configure Route Handlers as endpoints for external interfaces, apply Zod validation, manage server-bound secrets, and implement robust error handling.

How does data revalidation work with Next.js Server Actions?▼

Data revalidation with Next.js Server Actions ensures data consistency after server-side mutations. After a Server Action processes a secure mutation, trigger revalidation to refresh the cached data fetched by your server components.

Can I manage server-bound secrets securely with Next.js Server Components?▼

Yes, you can manage server-bound secrets securely with Next.js Server Components. Architectitectural best practices dictate using server components and server actions to keep secrets isolated from the client while enforcing validation with Zod.
