Can't use shared vite.config.ts in monorepo

[Rusinas]

Describe the bug

I have a monorepo (turborepo), where I've got a bunch of Vue apps and I want to share vite.config.ts across all of them. The problem is that I am getting tons of errors and I can't figure it out.

When I try to export shared config and use it, I get the following error:

failed to load config from C:\Users\andre\Desktop\Code\Stuff\vite-shared-config\apps\vue-project\vite.config.ts
error when starting dev server:
TypeError [ERR_UNKNOWN_FILE_EXTENSION]: Unknown file extension ".ts" for C:\Users\andre\Desktop\Code\Stuff\vite-shared-config\packages\vite-config\src\index.ts

Interestingly enough that if I change the import statement from import { ViteConfigBase } from 'vite-config' to import { ViteConfigBase } from '../../packages/vite-config/src/vite.config.base', everything will work just fine. But that's only for dev. If I want to build it inside of a Docker container, it will fail.

Changing the file extension to .js is not helping too.

I don't know if the problem is with Vite or Turborepo, but I am kinda desperate right now and will appreciate any help.
