@patak-dev new PR in here🙈

Hi @poyoho,

FYI this PR conflicts with other module loaders such as SystemJS. In my HTML file I have this line -

System.import("/some/other/module.js");

It has nothing to do with Vite, and until 2.8.0 Vite would leave it alone. Starting from 2.8.0, Vite tries to take ownership of that JS file because the line matches the new RegExp from this PR (const inlineImportRE = /\bimport\s*\(("[^"]*"|'[^']*')\)/g). Specifically, the "Word Boundary" \b means the RegExp matches System.import and not just standalone import("..."). This is probably not intentional.

so we need to ignore the . before the import🤔 @eugene1g

[patak-dev]

Thanks for the report @eugene1g, would you create an issue so we can properly track its resolution?
@poyoho maybe instead of the word boundary we could be explicit and use something like ([\s;:\(]|(\*\/))? We could also have issues with "import(, commented code, etc
