import mapcss from "https://deno.land/x/postcss_mapcss@VERSION/mod.ts";
import {
  bracketExtractor,
  Config,
  simpleExtractor,
} from "https://deno.land/x/mapcss@$VERSION/core/mod.ts";
import { presetTw } from "https://deno.land/x/mapcss@$VERSION/preset_tw/mod.ts";

const config: Config = {
  extractor: [simpleExtractor, bracketExtractor],
  preset: [presetTw()],
};

const css = `body {
  @apply antialiased text-gray-800
}
`;

const result = await postcss([mapcss(config)]).process(css);
