Tracks the deployed version of motus.dot.gov — FMCSA's USDOT Registration System — over time, so there's a public, timestamped record of when FMCSA ships new versions and what changed.
A scheduled job checks the site hourly and appends a new entry only when a version changes, so every row below is a real deploy. Liveness of the checker is visible in the Actions tab.
| Field | Where it comes from | Notes |
|---|---|---|
| Build | site footer | Frontend build timestamp (only on the page, not the API) |
| Web Version | site footer | Frontend bundle version (only on the page, not the API) |
| Server Version | site footer + API | Backend version |
| Seeder Version | site footer + API | Data seeder version |
| DB Migration Version | site footer + API | Migration timestamp (migrationTimestamp) |
| Migration # | API only | Numeric migrationVersion — not shown in the footer |
The footer is JavaScript-rendered, so capture uses a headless browser (Playwright). The same run
also reads the public, unauthenticated endpoint GET /api/auth/version for the numeric migration
number and nodeEnv.
data/versions.ndjson— append-on-change log; one JSON record per deploy.data/latest.json— current values + last-checked timestamp + status. Stable file for downstream consumers (e.g. motusbugs.com) to read.data/errors.ndjson— capture failures (site unreachable / footer missing).
