1# DOMException2An implementation of the DOMException class from NodeJS3 4NodeJS has DOMException built in, but it's not globally available, and you can't require/import it from somewhere.5 6This package exposes the [`DOMException`](https://developer.mozilla.org/en-US/docs/Web/API/DOMException) class that comes from NodeJS itself. (including all of the legacy codes)7 8<sub>(plz don't depend on this package in any other environment other than node >=10.5)</sub>9 10```js11import DOMException from 'node-domexception'12import { MessageChannel } from 'worker_threads'13 14async function hello() {15  const port = new MessageChannel().port116  const ab = new ArrayBuffer()17  port.postMessage(ab, [ab, ab])18}19 20hello().catch(err => {21  console.assert(err.name === 'DataCloneError')22  console.assert(err.code === 25)23  console.assert(err instanceof DOMException)24})25 26const e1 = new DOMException('Something went wrong', 'BadThingsError')27console.assert(e1.name === 'BadThingsError')28console.assert(e1.code === 0)29 30const e2 = new DOMException('Another exciting error message', 'NoModificationAllowedError')31console.assert(e2.name === 'NoModificationAllowedError')32console.assert(e2.code === 7)33 34console.assert(DOMException.INUSE_ATTRIBUTE_ERR === 10)35```36 37# Background38 39The only possible way is to use some web-ish tools that have been introduced into NodeJS that throws a DOMException and catch the constructor. This is exactly what this package dose for you and exposes it.<br>40This way you will have the same class that NodeJS has and you can check if the error is a instance of DOMException.<br>41The instanceof check would not have worked with a custom class such as the DOMException provided by domenic which also is much larger in size since it has to re-construct the hole class from the ground up.42 43The DOMException is used in many places such as the Fetch API, File & Blobs, PostMessaging and more. <br>44Why they decided to call it **DOM**, I don't know45 46Please consider sponsoring if you find this helpful47
