Node.js Best Practices

Quality patterns for Node.js services in production: observability, security, reliability, and operational readiness. Complements the nodejs skill (which covers runtime and module syntax).

When to Use

• Reviewing a Node.js service for production readiness
• Evaluating logging and observability strategy
• Auditing security posture (secrets, headers, rate limiting)
• Designing startup/shutdown lifecycle

Don't use for:

• Express route design (use express)
• npm dependency management (use nodejs)
• TypeScript configuration (use typescript)
