A CSS parser, transformer, and minifier written in Rust.
Nice. The CSS world could use a little processing shake up like this.
It looks like it doesn’t do bundling (standalone anyway). I suppose it would have to just invent a syntax for that, as I think Sass somewhat regrets the ambiguity of how it uses @import just like native CSS does and I wouldn’t blame anyone for not wanting to go down that road. It’s tricky territory, for sure, as inventing syntax kinda puts it into a different category of tool. I think it would be worth it though, as breaking up CSS into smaller files but bundling them in development is like… a thing people do.
So why run your CSS through this thing? From the docs, it looks like you’d wanna do that because…
it’s a minifier (looks like it’s cssnano under the hood),it does vendor prefixing (looks like it’s Autoprefixer under the hood),it can process as CSS modules (the classic library, not the native ones), andyou get sourcemaps.
Parcel CSS is fast and outputs small files. (Source: @devongovett)
I have no idea what powers Parcel CSS. though it feels similar in spirit to postcss-preset-env. I’m unsure if that’s what’s being leveraged or not. I guess PostCSS is required for Autoprefixer which is being used, so maybe? I just don’t see it in the package.json.
Will Parcel CSS become an ecosystem?
So I guess the big question is: If Parcel CSS becomes the CSS parser of choice, will we get plugins? And if we do, will it become a robust ecosystem like PostCSS plugins?
