Frontend Security Coder

This one's built for frontend developers who need to ship secure client-side code without becoming security experts overnight. It covers the practical stuff: preventing XSS with proper DOM manipulation, configuring Content Security Policy headers, sanitizing user-generated content with tools like DOMPurify, and handling authentication tokens safely. The scope is clearly defined too, focusing on hands-on implementation rather than audits or architecture reviews. What I like is the context-aware approach, like knowing when to use textContent over innerHTML, or how to implement clickjacking protection that doesn't break your dev environment. It's comprehensive enough to handle OAuth flows and WebAuthn while staying focused on the browser security model.
