Webpack 5 Tailwind bundle too large


This Content is from Stack Overflow. Question asked by Jnr

I have a stand-alone webpack application who’s only job is to bundle s|css. The output javascript file acts as the main style for the rest of the micro-service architecture.

webpack config:

const { merge } = require("webpack-merge");
const singleSpaDefaults = require("webpack-config-single-spa");

module.exports = webpackConfigEnv => {

  const defaultConfig = singleSpaDefaults({
    orgName: "stt",
    projectName: "styleguide",

  return merge(defaultConfig, {
    module: {
      rules: [
          test: /.(s(a|c)ss)$/,
          use: ['style-loader', 'css-loader', 'sass-loader', 'postcss-loader']

I have imported a minified version of tailwind from my .scss (about 3MB in size) using npx tailwindcss -o build.css --minify.

@import "tailwind.min.css";


module.exports = {
  plugins: [

After bundling, the ouput javascript is over 7MB in size.

How do I get the bundle size smaller?
