Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.
Warning: In modern browsers, this property has been deprecated. Service worker messages will now use the MessageEvent
interface, for consistency with other web messaging features.

object instance.
var mySWME = new ServiceWorkerMessageEvent(type, init);

data
: The event's data — this can be any type.origin
: A DOMString
that defines the origin of the corresponding service worker's environment settings object. lastEventId
: A DOMString
that defines the last event ID of the event source. source
: The ServiceWorker
or MessagePort
that sent the message. ports
: An array containing the MessagePort
objects connected to the channel sending the message. var init = { data : 'hello message', source : MessagePortReference, ports : MessagePortListReference } var mySWME = new ServiceWorkerMessageEvent('message', init);
