Describe the Bug

It`s not working https://github.com/vercel/turbo/tree/main/examples/with-tailwind#building-packagesui
Without assembly, the prefix for the ui library does not rebate and as a consequence styles are not applied when using the prefix in className

Expected Behavior

Prefixes must be worked

To Reproduce

1. Uncomment line https://github.com/vercel/turbo/blob/b1b74d78de1d1a6d8dce9f1f98e768c8274023f2/examples/with-tailwind/packages/tailwind-config/tailwind.config.js#L8

Hey @tknickman, i'm running into the same issue. When not bundling the UI package, the Tailwind prefixes do not work. In VSCode, it picks up the ui- prefix which I have set in the ui package's tailwind.config.js:

import sharedConfig from 'web-tailwind'

const config = {
  presets: [sharedConfig],
  prefix: 'ui-',
}

However, when importing a component into an app, the prefix classes are not applied. I've spent the day looking into it and haven't figured out a solution. Is this not possible without bundling the ui package?
