The previous handler opened a fresh postgres client (max: 1) on every call to /api/health and tore it down in the finally block. Under the prod monitoring cadence (probes every few seconds), that's a fresh TCP + TLS + auth handshake on every probe, plus connection-table churn on the Postgres side — fine for the trickle of curl-ish manual checks, slow-bleed under blackbox monitoring. Now we cache a module-level singleton postgres client dedicated to /api/health (max: 2, idle_timeout: 30) and reuse it across calls. Separate from the app's main DB pool (via @trails-cool/db's createDb) on purpose — so a starvation event on the main pool doesn't fail the liveness check and trigger a restart loop. Full repo: pnpm typecheck, pnpm lint, pnpm test all green. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> |
