This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
The ServiceWorkerGlobalScope.onmessage event of the ServiceWorkerGlobalScope interface is called whenever incoming messages are received.
ServiceWorkerGlobalScope.onmessage = function(MessageEvent) { ... } self.addEventListener('message', function(messageEvent) {
console.log('Handling message event:', messageEvent);
}
