tomevault-io Backend Node.js Skill
Core Principles
- Create connections once: DB/Redis pools are singletons — never instantiate per request.
- Validate at boundaries: All external input validated with Zod/TypeBox before business logic.
- Catch async errors: Unhandled promise rejections crash Node.js — always handle.
- Fail fast on bad config: Validate all env vars at startup with Zod — exit(1) if invalid.
- Graceful shutdown: SIGTERM handler closes connections, drains in-flight requests.
