SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires firebase-admin, zod, nodemailer.

What problem does it solve?

This Skill provides proven patterns to secure Next.js API routes and Firebase backends by enforcing authentication, input validation, rate limiting, CORS, error handling, and security headers.

Core Features & Use Cases

  • Enforcement of Firebase Admin token verification across routes to ensure only authenticated admins can perform sensitive operations.
  • Input validation with Zod to prevent malformed data, reduce security risks, and improve error handling.
  • Rate limiting, CORS controls, and security headers to mitigate abuse and protect data in transit.
  • Real-world use cases include admin-only user management, order processing notifications, and protected data access.

Quick Start

Use the skill to implement admin token verification and Zod input validation on your API routes to harden your backend.

FAQPage Schema
How do I secure Next.js API routes with Firebase authentication?▼

You can secure Next.js API routes by enforcing Firebase Admin token verification to ensure only authenticated users access sensitive endpoints. This approach validates identity tokens before processing server-side operations.

What is the best way to validate API input in Next.js to prevent malformed data?▼

The best way to validate API input is using Zod schemas to parse and verify request data. This prevents malformed data from reaching your backend logic and improves overall error handling.

How does rate limiting protect Firebase backend operations from abuse?▼

Rate limiting protects Firebase backend operations by restricting the number of requests a client can make in a given timeframe. This mitigates abuse and ensures fair resource allocation across users.

Do I need Firebase Admin to implement security headers and CORS controls in Next.js?▼

You do not need Firebase Admin specifically for security headers and CORS controls in Next.js, as these are configured at the routing level. Firebase Admin is required separately for token verification.

Can I use Zod for input sanitization on admin-protected endpoints?▼

Yes, you can use Zod for input sanitization on admin-protected endpoints to strip invalid data formats. It works alongside Firebase security rules to provide a production-ready protection pattern.
