The server demonstrates good security practices including password hashing with bcrypt, JWTs for authentication (secrets from environment variables), refresh token management (stored in DB with user agent and IP), HTTP-only and secure cookies, input validation with Zod, rate limiting, and a comprehensive global error handler that specifically catches and processes JWT-related errors. There are no obvious hardcoded secrets or dangerous patterns like 'eval'. The use of `req.ip` for rate limiting and token tracking relies on proper proxy configuration for accurate client IP in production environments.
