+# DOMException
+An implementation of the DOMException class from NodeJS
+
+This package implements the [`DOMException`](https://developer.mozilla.org/en-US/docs/Web/API/DOMException) class, from NodeJS itself.
+NodeJS has DOMException built in, but it's not globally available, and you can't require/import it from somewhere.
+
+The only possible way is to use some web-ish tools that have been introduced into NodeJS that throws an error and catch the constructor.
+This way you will have the same class that NodeJS has and you can check if the error is a instance of DOMException.
+The instanceof check would not have worked with a custom class such as the DOMexception provided by domenic which also is much larger in size.
+
+```js
+import DOMException from 'node-domexception'
+
+hello().catch(err => {
+  if (err instanceof DOMException) {
+    ...
+  }
+})
+
+const e1 = new DOMException("Something went wrong", "BadThingsError");
+console.assert(e1.name === "BadThingsError");
+console.assert(e1.code === 0);
+
+const e2 = new DOMException("Another exciting error message", "NoModificationAllowedError");
+console.assert(e2.name === "NoModificationAllowedError");
+console.assert(e2.code === 7);
+
+console.assert(DOMException.INUSE_ATTRIBUTE_ERR === 10);
+```
+
+## APIs
+
+This package exposes two flavors of the `DOMException` interface depending on the imported module.
+
+### `domexception` module
+
+This module default-exports the `DOMException` interface constructor.
+
+### `domexception/webidl2js-wrapper` module
+
+This module exports the `DOMException` [interface wrapper API](https://github.com/jsdom/webidl2js#for-interfaces) generated by [webidl2js](https://github.com/jsdom/webidl2js).
