Subpath imports

[kocv59]

Add https://nodejs.org/api/packages.html#subpath-imports to package.json then in the main css file import @import "#cssfiles/includes.css. There will be a SyntaxError Failed to find '#cssfiles/includes.css'.

"imports": {
  "#cssfiles/*.css": "./cssfiles/*.css"
}

We depend on resolve for this functionality. The upstream issue can be followed here: https://github.com/browserify/resolve/issues/327
