# ShadowRootRegistryChangeEventRootsEvent

typedef

Fired when the [event roots](module_utils_dom_shadowrootregistry-ShadowRootRegistry.md#function-getEventRoots) of the registered nodes change: a shadow root or a document starts or stops hosting a registered node. Fired once per change, after any [event-add](module_utils_dom_shadowrootregistry-ShadowRootRegistry.md#event-add) and [event-remove](module_utils_dom_shadowrootregistry-ShadowRootRegistry.md#event-remove) events, so read the current roots with [`getEventRoots`](module_utils_dom_shadowrootregistry-ShadowRootRegistry.md#function-getEventRoots).
