Bakmil Metro Schedule

What it is for

The Bakmil ↔ Nərimanov shuttle runs on its own timetable, and the question anyone standing on the platform has is the same one every time: when does the next one leave? That question deserves an answer in one screen, immediately, on a phone with poor reception — not an app to install, an account to make, or a page that loads a carousel first.

Open it and the next departures are already on screen. That is the entire product.

How the schedule stays current

The timetable is refreshed automatically once a day from Baku Metro’s own scheduling endpoint. That endpoint is undocumented and unofficial — it was found by inspecting the operator’s own site, not published as an API — which shapes how the update is handled.

If the source ever stops returning valid data, the job does not publish what it got. The previously published schedule is left exactly as it was and the failure is recorded separately, so the app keeps showing the last known-good timetable rather than an empty screen or invented times. Stale but true beats fresh and wrong when someone is deciding whether to run for a train.

Built small on purpose

Plain HTML, CSS and JavaScript, with no framework and no build step. The update script has no third-party dependencies at all — it runs on Node’s built-ins — so there is no dependency tree to audit and nothing to go stale in the background. It installs as a progressive web app if you want it on a home screen, and works as an ordinary page if you do not.
