[Bug]: dist CSS is not mapped in package.json

[Jean85]

Bug description

I'm trying to use this package with the Symfony Asset Mapper, which leverages ESM loading to avoid Node/npm as a requirement. This seems to work well with your package, except for the fact that the CSS dist file is not mapped in the package.json, so ESM does not see that.

Expected behavior

CSS is included in the package, so that CDNs like jsDelivr will consider it and add to the needed files.

Steps to reproduce

1. Go to jsDelivr
2. Click on ESM mode button
3. See that only the JS file is imported:

<script type="module"> 
    import tomSelect from 'https://cdn.jsdelivr.net/npm/[email protected]/+esm'
</script>

Additional context

The Symfony docs refer to the package.json configuration file as a way to fix this; we probably need to add keys like sass or style to the root of the package.json, like Bootstrap does: https://github.com/twbs/bootstrap/blob/e3e00b5002139adb0d5dadd6002e15b7b6cd371f/package.json#L40

I'm not understanding the relationship between jsDelivr and Symphony Asset Mapper. Can you explain more?

You cite Bootstrap as an example of something that's working correctly. However, the ESM "type" on jsDeliver (https://www.jsdelivr.com/package/npm/bootstrap) also doesn't include any CSS:

I'm happy to add a "style" property to package.json if you think that'll fix things.

The Symfony Asset Mapper uses jsDelivr to download precompiled ESM assets, hence avoiding the need for NodeJS locally.

For Bootstrap, there's no explicit CSS import, but I can add it manually into the Symfony Asset Manager configuration, importing dist/css/bootstrap.min.css, which is present inside the compiled package. For your package, you have the SCSS inside src/scss, but since it's not exposed in the package.json, is not compiled by jsDelivr.

As of now, I'm using your package without CSS, but if I would want to add it, I would need it; I don't know how to handle the different versions though...

If manually adding a path is an option, have you tried that with tom-select? They're all available on jsDelivr, there's no need for jsDelivr to "compile" them on its own: https://www.jsdelivr.com/package/npm/tom-select?path=dist%2Fcss&tab=files

Given that we added a style property to package.json in #810 as requested above, I'm going to close this issue. Feel free to comment if something is still not working quite right!
