Questions about vite-plugin-ssr-css

[silvenon]

I've been trying out your plugin for providing SSR CSS developer experience on Vite v6.0.0-beta.5, and have run into several problems, assuming that the plugin is intended to be used by adding it to my Vite config and nothing else.

• the source in resolveId never starts with just the virtual module name, it starts with \0 because it's linked in the HTML with /@id/__x00__, I'm not sure what's the intention there
• why does the load hook have this?

  if (!url.searchParams.has("direct")) {
    code = `export default ${JSON.stringify(code)}`;
  }

  why is it export default instead of just the content of the CSS? I haven't been able to get the injected link to actually produce the collected content, though, even though it manages to collect the CSS successfully…
• this plugin should produce the collected CSS during dev, but Vite's <style> tags still get injected, no? doesn't that result in duplicate styles? or is that not considered problematic?
• traversing modules also traverses Sass partials for me, so ?direct requests were failing for those because they were missing context, I've modified the traverse function to exit upon hitting a Sass file

I've tried to adapt the plugin to my Environment API setup, but since I don't really understand all of the plugin and that part of Vite deeply enough (despite your helpful comments) I didn't manage to succeed.

I can create a repro if it will help. I was just tired and wanted to write down everything that I can remember.
