The ServiceWorkerGlobalScope.onmessage event of the ServiceWorkerGlobalScope interface is called whenever incoming messages are received.
Note: Messages sent to service worker contexts (e.g. as the event object of onmessage are represented by MessageEvent objects in modern browsers, for consistency with other web messaging features. (They used to be represented by ServiceWorkerMessageEvent objects, which have now been deprecated.)
ServiceWorkerGlobalScope.onmessage = function(MessageEvent) { ... } self.addEventListener('message', function(messageEvent) {
console.log('Handling message event:', messageEvent);
}
