Official support for CRA about style9 HOT 3 CLOSED

Yes, the Style9Plugin sorts the generated CSS declarations, as this is required to make the styles deterministic. If you want to avoid this for CSS not generated from style9 you should be able to pass a regex to the plugin: new Style9Plugin({ test: /.../ }). You'll probably also need to look at the splitChunks and virtualFileName options so that you have something to match against.

This doesn't seem to be related to Create React App specifically, it's more about Webpack in general. I don't use CRA or CRACO so it's unlikely that I'll add a specific plugin for that, but the normal Webpack setup should work.

@johanholmerin Could you clarify why it's necessary for style9's styles to be deterministic if webpack generally doesn't care?

Could there be an option for the plugin to only sort it's own CSS by default?

It's to make sure that when pseudo classes and at-rules the order which they are generated doesn't affect what styles are applied.

The plugin already tries to only sort the CSS generated by style9, but since it's done after the files are combined it cannot be 100%. The solution is to separate the CSS generated from style9 from other CSS, as explained above.
