Conversation
The bull-board router is mounted at `/`, which means it answers every path nothing else claimed. Two consequences: it was open to anyone who could reach the worker's HTTP port, and because it was mounted before `/metrics` and the health routes, it also sat in front of them. The dashboard now only mounts when BULLBOARD_USERNAME and BULLBOARD_PASSWORD are both set, behind basic auth with a constant-time credential compare, and read-only unless BULLBOARD_READONLY=0. Metrics and health are registered first so they keep answering with no credentials, whatever the dashboard is doing. The Coolify template gave opworker a public hostname it has no use for; it is dropped, and the dashboard is off there by default. Express app construction moves to app.ts so the routes can be tested without booting workers, cron or the datastore clients. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

| If you want the queue dashboard, set `BULLBOARD_USERNAME` and `BULLBOARD_PASSWORD`, remove `DISABLE_BULLBOARD`, and reach it through your own proxy or an SSH tunnel. Basic auth is a thin lock, so do not put it on a public hostname on its own. The dashboard is read-only unless you also set `BULLBOARD_READONLY=0`. |

Encrypt the worker dashboard hop.
Caddy terminates external TLS but forwards requests to op-worker:3000 over HTTP. An observer on that internal network can capture the dashboard Authorization header. Use an encrypted upstream or prevent dashboard exposure outside a trusted, isolated network.

Send a valid metrics failure response.
When register.metrics() rejects with an Error, res.end(error) passes an unsupported body type to Node.js ServerResponse.end(). The handler can throw before the scrape receives a response. Log the error with logger.error({ err: error }, ...) and end with a generic string or JSON body.

What changed
The bull-board router is mounted at
/. An Express router mounted at the root answers every path that nothing registered before it claimed, so two things followed from it being mounted first:/metrics,/healthcheck,/healthz/liveand/healthz/ready, so any middleware put in front of the dashboard would also have covered them.This PR:
/metricsand the three health routes before the dashboard, so they answer with no credentials regardless of how the dashboard is configured. This is the part most worth not regressing, and the test covers it in every dashboard configuration.BULLBOARD_USERNAMEandBULLBOARD_PASSWORDare set. With no credentials there is nothing to mount it behind, so it is not mounted at all and/and/api/queuesfall through to Express' 404.DISABLE_BULLBOARDstill works as an additional off switch.serverAdapter.getRouter(). Missing or wrong credentials get a 401 withWWW-Authenticate: Basic. Username and password are compared withcrypto.timingSafeEqual, and both comparisons always run so a wrong username costs the same as a wrong password.{ readOnlyMode: true, allowRetries: false }. SetBULLBOARD_READONLY=0(orfalse) to get the write actions back.SERVICE_FQDN_OPBULLBOARDfromopworkerin the Coolify template and setsDISABLE_BULLBOARD=1there. The service healthcheck talks tolocalhost:3000, so it is unaffected.Express app construction moves from
index.tsinto an exportedcreateApp()inapps/worker/src/app.ts. That is what makes the routes testable:app.test.tsboots the app on port 0 and drives it over a real socket without starting workers, cron or any datastore client. The route handler bodies are moved verbatim.This changes defaults
Worth calling out in the changelog. Operators who currently open the dashboard with no credentials will get a 404 until they set
BULLBOARD_USERNAMEandBULLBOARD_PASSWORD. Once they do, it is read-only unless they also setBULLBOARD_READONLY=0.Evidence (line numbers as of 2d4f21e, before this change)

What I left out
supertestdev dependency. The test listens on port 0 and usesfetch, which avoids touching the lockfile.self-hosting/anddocker/were not changed. Only the Coolify template gave the worker a public hostname; the others do not expose the worker port outside the compose network.apps/worker/src/app.tsstill has fourreqparameters that biome flags as unused, in the moved route handlers. They are pre-existing and I moved the handler bodies unchanged rather than mixing a rename into this diff.Summary by CodeRabbit
