Serializable errors

The DOMException, Error, EvalError, RangeError, ReferenceError, SyntaxError, TypeError, and URIError objects are serializable. You can call structuredClone() on an error object or pass it to a worker using postMessage().

Error.serializable object

Serializable objects are objects that can be serialized and later deserialized in any JavaScript environment ("realm"). This allows them to, for example, be stored on disk and later restored, or cloned with Window.structuredClone, or shared between workers using DedicatedWorkerGlobalScope.postMessage().

Use cases

  • Using Serializable errors

    The DOMException, Error, EvalError, RangeError, ReferenceError, SyntaxError, TypeError, and URIError objects are serializable. You can call structuredClone() on an error object or pass it to a worker using postMessage().

Cautions

  • Limited browser support. Check compatibility before use.

Accessibility

  • When updating the DOM dynamically, announce important changes to assistive technology with aria-live regions.
