ServiceWorkerContainer.onmessage

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 onmessage property of the ServiceWorkerContainer interface is an event handler fired whenever a message event occurs — when incoming messages are received to the ServiceWorkerContainer object (e.g., via a MessagePort.postMessage() call).

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.)

Syntax

ServiceWorkerContainer.onmessage = function(messageevent) { ... }

Example

// TBD
