Add the ability to prevent transforming some assets files

[CGNonofr]

Description

In my app, I use the new URL('...', import.meta.url) syntax to get some assets URLs, including some CSS files. I then reference that asset in a document inside an iframe.

The problem is: vite is transforming my css files to resolve image references (url(<image path>)). While it's fine and expected in most cases, it's a big problem in my specific case, because the content of the css file is then digested by some code that already tries to resolve the real image urls inside the css at runtime.

I didn't find any way currently, even hacky, to prevent vite from trying to transform some asset files using the new URL(..., import.meta.url) syntax (except renaming the file to change its extension)

There is an assetsInclude option that seems to do what I want, but it doesn't seem to support the new URL(...) syntax as it seems to transform my asset to an html page displaying a Unexpected end of input error 🤔

Suggested solution

I see 2 possible solutions:

• add a query parameter on asset urls (like new URL('./myImage.png?raw', import.meta.url))
• make assetsInclude work with new URL(...) syntax if it's relevant, or add another option

Just realized the build behavior is different than the dev behavior: in build mode, asset loaded with the new URL(...) syntax never get transformed, so a third solution can be to homogenize behaviors and consider it as a bug?
