calendar-station

Provider-agnostic calendar-watch core. Outbox commit, trigger worker, Store interface, handler interface. Promise + Result API by default; /effect subpath for Effect-TS users.

import { createStation, ok, UserId } from "calendar-station"
import { googleCalendarProvider } from "google-calendar-station"

const station = createStation({
  store,                       // your StoreAdapter implementation
  handler: async (event) => {  // your business logic per change
    console.log(event.summary, event.status)
    return ok(undefined)
  },
  providers: { google: googleCalendarProvider({ /* ... */ }) },
})

await station.start()

Sibling to mailbox-station — same architecture (commit-then-trigger, branded ids, tagged errors), different upstream. Webhooks instead of Pub/Sub, syncToken instead of historyId, calendar events instead of mail messages.
