Worker: error event
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
Note: This feature is available in Web Workers, except for Service Workers.
The error event of the Worker interface fires when an error occurs in the worker.
Syntax
Use the event name in methods like addEventListener(), or set an event handler property.
js
addEventListener("error", (event) => { })
=> { }
Event type
A generic Event.
Example
The following code snippet creates a Worker object using the Worker() constructor and sets up an onerror handler on the resulting object:
js
const myWorker = new Worker("worker.js");
myWorker. => {
console.log("There is an error with your worker!");
};
