@vanilla-extract/vite-plugin@4.0.4 hangs Vite build

[emondpph]

Describe the bug

I am experiencing an issue upgrading the @vanilla-extract/vite-plugin to version 4.

It seems the commit in 4.0.4 creates an issue on my end where Vite build will succeed (generated CSS is OK) but the Vite process itself does not close. I need to force close the Vite process (CTRL-C)

The release which seems to be problematic on my end: https://github.com/vanilla-extract-css/vanilla-extract/releases/tag/%40vanilla-extract%2Fvite-plugin%404.0.4

This bug was not happening in version 3.9 or 4.0.3.

I seem to be able to fix the hanging by adding line 105 within the code of the vite-plugin. My Vite configuration is having two plugin: @rollup/plugin-typescript (for generating DTS files) and Vanilla Extract.

Not sure what is happening here...

Hey @askoufis, sorry about that. It was late and I focused more on finding the issue in the vite-plugin code and which version the problem started to appear. Thanks for creating the repo with reproduction.

I can tell that this seems to be an incompatiblity with @rollup/plugin-typescript, but the why I'm not sure.

Replacing @rollup/plugin-typescript with https://github.com/qmhc/vite-plugin-dts also fixes the hanging.
