When importing the SFC file in another package from the vite application, the following error is output.

Failed to load module script: The server responded with a non-JavaScript MIME type of "text/html". Strict MIME type checking is enforced for module scripts per HTML spec.

Also, during vite build, an error is output that rollup cannot parse the SFC file. The following is when running it in my local environment.

$ vite build

Work repository https://github.com/ushironoko/vite-playground

The repository consists of mono repos, and another packages can be found in packages / vite-components.

This worked fine when I placed the SFC file in the same workspace. Do you know the cause?

Thank you.

Can you try DEBUG=vite* vite + DEBUG=vite* vite build and provide the logs?

Look caused by compiler ts.We can track here.#6

@underfin, @ushironoko Is Using Version 0.10.2 Which Is Not Typescript Supported. Typescript Support Added In 0.11.0.

@bekalshenoy @underfin Thank you for the review. I raised vite to a TypeScript compatible version and rebuilt it, but the error was not resolved. Also, even if you delete the lang =" ts " and defineComponent of the component to be imported, the build was not successful...

This issue seems to be similar to #74 . When I started the development server with vite, the same console error was output in the browser.

Just realized the build part isn't working yet.

Should work both for dev and build in 12.0.0.

@yyx990803 Thank you for the great work.👍
