Schnack is a minimal Node.js comment service. Because it is commonly deployed for static sites with small teams, practical hardening focuses on basic auth controls, abuse throttling, and dependency hygiene.
¶ 1) Protect admin actions and deployment secrets
- keep admin credentials and JWT or session secrets in environment secret storage
- avoid exposing management functions on public interfaces without authentication
- rotate secrets after server migration or staff changes
- enforce reverse-proxy TLS and rate limiting
- moderate first-time or anonymous comments before publishing
- cap request body size and reject malformed payloads early
¶ 3) Maintain Node.js runtime and dependency security
- pin npm dependencies and audit for known vulnerabilities
- patch Node.js runtime on supported LTS releases
- run the service as non-root user with least-privilege file permissions
