Provides comprehensive security coding guidelines to preempt common vulnerabilities in both frontend (XSS, sensitive data exposure) and backend (injections, authentication/authorization, CORS) and to guide secure code reviews, secure implementations, and safe input handling.
Review these guidelines during code development and code reviews to ensure security by default.

To prevent XSS and injection vulnerabilities, apply secure coding guidelines for safe input validation, robust authentication, and proper CORS configuration across frontend and backend contexts. These rules encode security requirements directly into your development workflows.
Secure authentication and authorization practices involve enforcing robust backend access controls, preventing SQL or NoSQL injection, and safely handling environment variables. Following structured coding guidelines ensures security by default and reduces production risks during feature design and review.
Safe user input validation requires checking and sanitizing all inputs before rendering on the frontend to prevent XSS and sensitive data exposure. Secure coding rules provide actionable steps to ensure safe input handling and reduce vulnerability risks.
Proper CORS configuration prevents unauthorized cross-origin requests and sensitive data exposure in production systems. Backend security guidelines define actionable coding rules for safe environment variable usage and secure error handling to mitigate these risks.
No specific frameworks are required to apply these secure coding guidelines. They provide general actionable rules and review practices for preventing common frontend and backend vulnerabilities, ensuring security by default across any development workflow.
You should refer to secure coding rules when designing, implementing, or reviewing features to ensure security by default. Applying these guidelines during code development and code reviews helps preempt common vulnerabilities and reduce risk in production systems.
