SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill addresses critical security vulnerabilities in TypeScript development, helping to prevent common attacks like Cross-Site Scripting (XSS) and ensuring the integrity of your application.

Core Features & Use Cases

Input Validation: Utilizes Zod for robust schema validation of incoming data, preventing unexpected or malicious inputs.
XSS Prevention: Implements sanitization techniques to neutralize harmful HTML/script content.
Dependency Auditing: Guides on using package managers to identify and fix security vulnerabilities in project dependencies.
Sensitive Data Handling: Promotes secure practices for managing API keys and other sensitive information, discouraging hardcoding.

Quick Start

Use the security skill to validate user input against a defined schema and sanitize any potentially harmful HTML.

FAQPage Schema

How do I prevent XSS in TypeScript applications?▼

To prevent XSS in TypeScript, sanitize user-generated HTML content using DOMPurify to neutralize harmful scripts before rendering. This strips malicious code, maintaining DOM integrity and protecting web applications from cross-site scripting attacks.

What's the best way to validate input data in TypeScript?▼

The best way to validate input data in TypeScript is by defining strict schemas with Zod. Zod parses incoming data against your schema, rejecting unexpected inputs and ensuring type safety throughout your application's runtime.

How do I audit dependencies for vulnerabilities using pnpm?▼

To audit dependencies for vulnerabilities using pnpm, run the package manager's audit command to identify security flaws in your project dependencies. This flags known vulnerabilities, allowing you to update packages and mitigate risks.

How to handle sensitive API keys securely in TypeScript?▼

To handle sensitive API keys securely in TypeScript, store them in environment variables rather than hardcoding them into your source files. This prevents accidental exposure in version control and isolates sensitive data from application logic.

Does TypeScript input validation with Zod prevent injection attacks?▼

TypeScript input validation with Zod prevents injection attacks by enforcing strict schema constraints on incoming data. By rejecting malformed payloads at the application boundary, Zod ensures only structurally valid data reaches your logic.
