SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill addresses the critical need for secure coding practices in TypeScript applications, helping developers prevent common vulnerabilities and protect sensitive data.

Core Features & Use Cases

Input Validation: Enforces robust data validation using libraries like Zod or Joi.
XSS Prevention: Guides on sanitizing HTML output to prevent Cross-Site Scripting attacks.
Secure Authentication: Provides patterns for secure password hashing and token management.
Use Case: A developer building a user authentication system can use this Skill to ensure all user inputs are validated, passwords are securely hashed with bcrypt, and JWT tokens are implemented with appropriate security options.

Quick Start

Apply TypeScript security best practices to the provided codebase.

FAQPage Schema

How do I validate user input in TypeScript to prevent vulnerabilities?▼

To validate user input in TypeScript, you should enforce robust data validation using libraries like Zod or Joi. This prevents common vulnerabilities by ensuring all incoming data matches expected schemas before processing.

What's the best way to sanitize HTML output and prevent XSS in TypeScript?▼

The best way to prevent XSS in TypeScript is by sanitizing HTML output using libraries like DOMPurify. This ensures malicious scripts are stripped from the output before rendering in the browser.

How do I implement secure authentication mechanisms in a TypeScript API?▼

Implement secure authentication in TypeScript by using bcrypt for password hashing and managing JWT tokens with appropriate security options. This protects sensitive user credentials during web development.

Can I use Prisma with TypeScript to secure database queries against injection?▼

Yes, Prisma can be used with TypeScript to enforce secure coding standards and protect against database injection. It provides a type-safe query builder that inherently sanitizes inputs when interacting with the database.

Does this TypeScript security guidance align with OWASP guidelines?▼

Yes, this TypeScript security guidance strictly adheres to OWASP guidelines for web development and API security scenarios. It focuses on input validation, output sanitization, and secure authentication to mitigate common risks.

Why do I need a dedicated library for input validation instead of manual checks?▼

You need a dedicated library like Zod or Joi for input validation because manual checks often miss edge cases and lead to vulnerabilities. These libraries enforce robust schemas, ensuring comprehensive data validation for secure applications.
