DedicatedWorkerGlobalScope: messageerror event

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

Examples

Listen for messageerror using addEventListener():

// inside worker.js

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

The same, but using the onmessageerror event handler property:

// inside worker.js

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