?? bug report

Importing and using some components from the FluentUI component library result in the app crashing as described in this issue . A Microsoft MVP Hotell replied to that issue suggesting it has to do something with how parcel bundles things.

?? Possible Solution

?? Context

I was just starting a React app that was using Fluent UI and as soon as I started building the application layout and added a the top navigation the app started crashing.

?? Code Sample

I've cloned your repo and tried both yarn start and yarn build but both worked fine in the browser

tpalacino · 2023-09-27T19:36:09Z

I've cloned your repo and tried both yarn start and yarn build but both worked fine in the browser

Are you suggesting it's an issue with npm?

mischnic · 2023-09-27T19:39:00Z

Are you sure it's failing for you? (Delete node_modules and run npm ci) And if yes, is it with yarn start or yarn build

tpalacino · 2023-09-27T19:53:59Z

Apparently I committed the workaround to that repo. I just removed it and now if you pull the latest, the issue can be reproduced.

tpalacino · 2023-11-08T15:34:39Z

@mischnic Is there any update you can provide here?

tpalacino · 2024-05-07T00:36:48Z

@mischnic is anybody looking into this bug?

mischnic · 2024-05-09T09:51:55Z

I can reproduce it now. This does seem like a Parcel bug, but do note that upgrading fluentui also happens to fix it (by coincidence at least in your reproduction)
