What problem does it solve?

This Skill addresses critical security vulnerabilities in web applications, particularly those built with Next.js and React, by enforcing best practices for input validation, XSS prevention, and secret management.

Core Features & Use Cases

• Input Validation: Ensures all data from client requests is rigorously validated on the server-side using Zod.
• XSS Prevention: Protects against Cross-Site Scripting attacks by sanitizing user-generated content.
• Security Headers: Configures essential HTTP security headers to mitigate various web vulnerabilities.
• Rate Limiting: Implements rate limiting to prevent abuse and denial-of-service attacks.
• Secret Management: Enforces the principle of keeping sensitive information server-only.
• CSRF & Cookie Security: Guides the secure handling of session cookies.
• Use Case: When deploying a new Next.js application that handles user-submitted data, use this Skill to ensure all API routes are protected against common web exploits.

Quick Start

Apply security best practices to the Next.js application by configuring security headers and implementing server-side validation with Zod.
