Processing CSSStyleDeclaration'esq css

[Juice10]

I'm trying to process CSS supplied as json, eg. {backgroundImage: 'url(./image.png)', color: 'yellow'}.

const cssSyntax = {backgroundImage: 'url(./image.png)', color: 'yellow'};
const result = await postcss(plugins).process(cssSyntax);

This doesn't work as-is, does anyone know how I could do this?

You need to use this parser https://github.com/postcss/postcss-js/

But your CSS must have selector, not just property list.

Thanks @ai!
I can wrap it in a selector, and afterwards unwrap it, and postcss-js should totally work for my use case, thanks!
