Build a Nextcloud app on the Conduction stack — Part 3: Schema-driven integrations
· 7 min read
This is Part 3 of the nine-part app-building tutorial series. Part 2 wired the pet and order schemas. Part 3 makes those orders appear in every user's Nextcloud Calendar (without writing a controller, an event listener, or any per-app calendar glue).
The trick: OpenRegister already ships an ICalendarProvider (RegisterCalendarProvider) that exposes any schema with a calendarProvider block as a virtual calendar. You declare the block on the order schema. NC Calendar shows the events. That's the whole story.
