16-38: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick winRun the independent health checks concurrently.
checkS3Bucket(),checkRequestApi(),checkDatasette(), and (conditionally)checkRedis()are awaited sequentially inside the array/object literals. Each is an independent network call, so this PR adds a fourth serialized round trip to/health, multiplying worst-case latency for a route that's typically polled with tight timeouts.♻️ Proposed fix using Promise.all
router.get('/', async (req, res) => { - const dependencies = [ - { - name: 's3-bucket', - status: await checkS3Bucket() ? 'ok' : 'down' - }, - { - name: 'request-api', - status: await checkRequestApi() ? 'ok' : 'down' - }, - { - name: 'datasette', - status: await checkDatasette() ? 'ok' : 'down' - } - ] + const [s3Ok, requestApiOk, datasetteOk] = await Promise.all([ + checkS3Bucket(), + checkRequestApi(), + checkDatasette() + ]) + const dependencies = [ + { name: 's3-bucket', status: s3Ok ? 'ok' : 'down' }, + { name: 'request-api', status: requestApiOk ? 'ok' : 'down' }, + { name: 'datasette', status: datasetteOk ? 'ok' : 'down' } + ] if (config.redis) { dependencies.push({ name: 'redis', status: await checkRedis() ? 'ok' : 'down', required: false }) }🤖 Prompt for AI Agents

Description
Adds Datasette to the
/healthendpoint dependency checks and introduces an overall health status.The endpoint now reports
ok,degraded, ordownat the top level. Required dependencies such as S3, request API, and Datasette returningdowncause the endpoint to return HTTP 500. Redis is marked asrequired: false, so if Redis is down the top-level status becomesdegradedwhile the endpoint still returns HTTP 200.Related Tickets & Documents
QA Instructions, Screenshots, Recordings
Run the focused health tests and lint:
Expected result: all tests pass and lint returns no errors.
No screenshots or recordings are included because this is a backend health endpoint change.
Added/updated tests?
[optional] Are there any post deployment tasks we need to perform?
Configure monitoring, such as Upptime, to treat HTTP 500 responses as down and top-level
{"status":"degraded"}responses as degraded.[optional] Are there any dependencies on other PRs or Work?
None.
