ServiceWorkerGlobalScope: push event

The push event is sent to a service worker's global scope (represented by the ServiceWorkerGlobalScope interface) when the service worker has received a push message.

This event is not cancelable and does not bubble.

Syntax

Use the event name in methods like addEventListener(), or set an event handler property.

addEventListener("push", (event) => { })

onpush = (event) => { }

Event type

A PushEvent. Inherits from Event.

Event properties

Inherits properties from its parent, ExtendableEvent. Additional properties:

PushEvent.data Read only

Returns a reference to a PushMessageData object containing data sent to the PushSubscription.

Example

This example sets up a handler for push events that takes JSON data, parses it, and dispatches the message for handling based on information contained within the message.

self.addEventListener(
  "push",
  (event) => {
    let message = event.data.json();

    switch (message.type) {
      case "init":
        doInit();
        break;
      case "shutdown":
        doShutdown();
        break;
    }
  },
  false,
);
