[mwoodward-atd]

When attempting to instantiate a Client object in a Vite/Vue3 app, the error Uncaught TypeError: util.inherits is not a function is thrown.

Environment

• Node 18.16

Steps to Reproduce

1. Create a new Vite/Vue3 app, install dependencies, and launch app

npm create vite@latest duo-vite-test -- --template vue
cd duo-vite-test
npm install
npm install @duosecurity/duo_universal
npm run dev

2. Instantiate Client in App.vue <script setup> block

import { Client } from '@duosecurity/duo_universal'

const client = new Client({
  clientId: 'theclientid',
  clientSecret: 'theclientsecret',
  apiHost: 'theapihost',
  redirectUrl: 'http://localhost:5173',
})

3. When the app reloads, the following error is thrown:

Thanks @AaronAtDuo ! I'll take a look at that. Appreciate the reference.

[AaronAtDuo]

I'm looking through those myself. I'm not a Node and/or JS dev so bear with me :)

[AaronAtDuo]

It doesn't look like there's a great solution for this, but maybe the best one is to introduce some sort of polyfill to work around this?

Thanks @AaronAtDuo -- that's what we've found so far as well, so we'll dig into that angle a bit more.
