dom-exception-modern

Native DOMException migration helpers for JavaScript and TypeScript.

domexception is deprecated because modern runtimes expose DOMException directly. This package default-exports the native constructor for migration compatibility and adds small typed helpers for converting and checking errors.

Install

npm install dom-exception-modern

Usage

import DOMException, { createDOMException, isDOMException } from "dom-exception-modern";

const error = new DOMException("Cannot modify this value", "NoModificationAllowedError");

if (isDOMException(error)) {
  console.log(error.code);
}

createDOMException("Aborted", "AbortError");

Migration Position

dom-exception-modern is an independent alternative or migration helper for projects moving away from domexception. It is not affiliated with the original package maintainers or project.
