DedicatedWorkerGlobalScope: messageerror event

Note: This feature is only available in Dedicated Web Workers.

The messageerror event is fired on a DedicatedWorkerGlobalScope object when it receives a message that can't be deserialized.

This event is not cancellable and does not bubble.

Syntax

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

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

onmessageerror = (event) => { }

Listen for messageerror using addEventListener():

// worker.js

self.addEventListener("messageerror", (event) => {
  self.postMessage("Error receiving message");
  console.error(event);
});

The same, but using the onmessageerror event handler property:

// worker.js

self.onmessageerror = (event) => {
  self.postMessage("Error receiving message");
  console.error(event);
};
