I need to ask @diox's opinion on this...

I'm +1 to LightningCSS — already using it with COMPRESS_PRECOMPILERS.

But I've also been looking at some of the older options (YUI?) and thinking we could trim them out. (Deprecate them)

So... given how small the filter here, is the solution here to document how folks create a filter for any given tool, and then reduce the amount we ship?

🤔

[jeffbowen]

Oh right, guess I could just use COMPRESS_PRECOMPILERS. I'll leave it up to you guys. Yeah, if you do trim out some of the older options it might make it clearer that there's a more preferable approach for using other simple precompilers. Thanks!

[jeffbowen]

Actually, guess I can't use COMPRESS_PRECOMPILERS in my case since I'm using Sass in the project I'm working on. Will stay tuned to hear what you guys think the ideal approach would be.

[diox]

Yeah, I'd rather get rid of these kind of small classes that are wrapper around various command-line libraries. Maybe they could be grouped together in a django-compressor-contrib package or something like that with different maintainers. Or we could improve documentation to encourage users to make their own as needed like @carltongibson is suggesting.

@jeffbowen in the meantime you can use your filter class locally no problem.
