EventRepository

@webda/models


Class: EventRepository<T>

Defined in: packages/models/src/repositories/event.ts:26

Repository decorator that wraps another repository with event emission.

Emits "before" events (Create, Update, Patch, Delete, PartialUpdate, Query) before delegating to the underlying repository, then emits "after" events (Created, Updated, Patched, Deleted, PartialUpdated, Queried) on success.
