Opinion about tailwindcss compile by javascript

I saw the windicss. Windi CSS is fully compatible with Tailwind CSS v2.
I read about the compile page. (https://windicss.org/integrations/javascript.html)
I think it’s able to generate the css from db content.
Generate css >> upload by ajax-post >> import css file uploaed

const { Processor } = require("windicss/lib");
const { HTMLParser } = require("windicss/utils/parser");

export function generateStyles(html) {
  // Get windi processor
  const processor = new Processor();

  // Parse HTML to get array of class matches with location
  const parser = new HTMLParser(html);

  // Generate preflight based on the HTML we input
  const preflightSheet = processor.preflight(html, false);

  console.log(preflightSheet);

  const PREFIX = "";
  const outputCSS = [];
  let outputHTML = "";
  let indexStart = 0;

  parser.parseClasses().forEach((p) => {
    // add HTML substring from index to match start
    outputHTML += html.substring(indexStart, p.start);

    // generate stylesheet
    const style = processor.compile(p.result, PREFIX);

    // add the styleSheet to the styles stack
    outputCSS.push(style.styleSheet);

    // append ignored classes and push to output
    outputHTML += [style.className, ...style.ignored].join(" ");

    // mark the end as our new start for next iteration
    indexStart = p.end;
  });

  // append the remainder of html
  outputHTML += html.substring(indexStart);

  // Build styles
  const MINIFY = false;
  const styles = outputCSS
    // extend the preflight sheet with each sheet from the stack
    .reduce((acc, curr) => acc.extend(curr), preflightSheet)
    .build(MINIFY);

  return {
    styles,
    outputHTML
  };
}

const test111 = generateStyles("<div class='p-3'>test</div>");
console.log(test111);
