Missmatch between dev / build for typescript files with ?url

anuejn commented 2 weeks ago

Describe the bug

I am trying to import a typescript file with ?url in my application. I would like to get the file back with already stripped types (so as a js file). This is what happens in dev mode. In production mode, the file is left untouched and I get the raw typescript source.

The documentation is not very clear about what should happen, but I would argue, that this missmatch is a bug.

Reproduction

https://stackblitz.com/edit/vitejs-vite-rdougd?file=main.js,test.ts&terminal=dev

Steps to reproduce

Run npm dev to get the typescript compiled to js.
Run npm build && npm preview to get the typescript in its raw form
Observe, that there is a missmatch
