Describe the bug The NODE_DEBUG global is undefined when using a bundler such as Vite which doesn’t support node shimming. A repo with a reproduction of the error is available here.

This issue was originally raised in the Vite repository but I have been advised that the issue is related to how @azure/event-hubs is bundled. See the original issue here.

To Reproduce Steps to reproduce the behavior:

1. Clone the above repo
2. Run yarn install
3. Run yarn start
4. Open the browser console and note the error.

Expected behavior There should be no error.

@andrewcourtice It looks like our dependency rhea requires some shims to work in the browser, so we’ll need to push updates to that before we can fully resolve the issue you’re seeing.

That said, I was able to come up with a workaround for your sample by creating a shims file and importing it in your index.ts.

Here’s what it looks like: npm install --save buffer process src/shims.ts

import * as process from "process";
import { Buffer } from "buffer";
Object.assign(self, {
  process,
  global: self,
  Buffer,
});

src/index.ts

import "./shims";

// rest of code follows

Is this workaround something you’d be able to use until we can update our dependencies/verify we’re not relying on shims in our clients?

@chradek Can we log an issue for rhea regarding this?
