process.env.NODE_DEBUG is undefined

Describe the bug

This may be my misunderstanding of how env variables are processed in Vite but in my project the value process.env.NODE_DEBUG is undefined when compiling a third-party dependency. The dependency in question is @azure/event-hubs.

This is not an issue when using another bundler such as webpack, parcel, or rollup.

I have attempted this solution: https://github.com/vitejs/vite/discussions/2344 but I couldn’t get it to work…

Reproduction

I have put together a reproduction of the issue here.

However, for clarity here are the steps:

1. Create a blank vite project
2. Add @azure/event-hubs as a dependency
3. Import anything from @azure/event-hubs

@jacobclevenger Thanks for getting back to me. I’m aware of how to use env variables via import.meta in Vite, unfortunately the issue is that a third-party package references process.env.NODE_DEBUG which is out of my control.

This now has a workaround here: https://github.com/Azure/azure-sdk-for-js/issues/14496#issuecomment-808442337

Going to close this as it is an issue with their library and they are working on fixing it
