Provides an abstract Tasker class with sync and async execution variants (e.g., BookingEmailAndSmsTasker, CalendarsTasker, WebhookTasker). Uses a DI container to inject task implementations and supports fallback between direct execution and Trigger.dev tasks. This pattern is reusable for any background job system and demonstrates clean separation of concerns.

Implements a factory for versioned webhook payload builders (e.g., v2021-10-20). Each builder (booking, payment, recording, OOO) extends a base class and implements canHandle/fetchEventData. The factory selects the correct builder based on event type and version. This pattern is reusable for any event-driven webhook system and handles backward compatibility cleanly.

A set of React hooks and UI components (e.g., useBooking, useEventType, useAtomUpdateSchedule, BookerEmbed) that wrap the platform API v2 endpoints. They provide a clean, typed interface for external consumers to embed scheduling functionality. The hooks use TanStack Query for caching and state management, and are designed to be extracted and used in any React application.

A factory that creates singleton adapters for calendar subscription providers (Google Calendar, Office365). It includes logic to filter out generic calendar suffixes (holidays, contacts, etc.) from subscriptions. The DefaultAdapterFactory uses lazy initialization and a get() method, making it easy to extend with new providers. This pattern is reusable for any multi-provider adapter system.
