Two cleanups in one pass for the v1.14.0 'works on any platform' theme:
1. Response helpers — merged src/utils/responses.js and the root-level
response-helpers.js into a single module at src/utils/responses.js.
The old module had a richer set (created, noContent, validationError,
unauthorized, forbidden, notFound, conflict) and is now re-exported
from the new location. Updated 15 routes to import from
src/utils/responses and deleted the root response-helpers.js.
2. Error logger — error-handler.js now uses the unified
src/utils/logging.js#logError (same one src/app.js uses), so all errors
go to one log file with one rotation policy. Removed the dead
asyncHandler export (the real one is in src/utils/async-handler.js
and is used everywhere). Deleted the legacy error-logger.js.
Both are invisible to users — same HTTP response shapes, same log file
path, same error format. Internal-only refactor.
The readiness probe was using asyncHandler directly, but this codebase's
asyncHandler has signature (logError, fn, context) — first arg is the logger.
Switched to boundAsyncHandler which is what every other route in src/app.js
uses. Verified working on both DNS2 (Docker) and Contabo (systemd).
8 new tests in __tests__/health-endpoints.test.js verify both endpoints.
The readiness probe was crashing with 'res.status is not a function' because
asyncHandler(async (req, res) => {...}, 'health-ready') was called directly,
but asyncHandler's signature is (logError, fn, context) — first arg is the
logger, not the handler. The fix uses boundAsyncHandler like all other routes
in the file do.
Added 8 unit tests for both /health/live and /health/ready:
- live always 200 (liveness ≠ readiness)
- ready returns 503 when config/services/docker fail
- no 'res.status is not a function' crash when dependencies fail
- all 4 check keys present in response
Also added MONITORING_PUBLIC env var (defaults true) and the new health
endpoints to PUBLIC_ROUTES so k8s probes can hit them without auth.
