webpack.mix.js

let mix = require("laravel-mix");
let tailwindcss = require("tailwindcss");
let glob = require("glob-all");
let PurgecssPlugin = require("purgecss-webpack-plugin");

/**
 * Custom PurgeCSS Extractor
 * https://github.com/FullHuman/purgecss
 * https://github.com/FullHuman/purgecss-webpack-plugin
 */
class TailwindExtractor {
  static extract(content) {
    return content.match(/[A-z0-9-:\/]+/g);
  }
}

mix.postCss("./src/styles.css", "public/css", [tailwindcss("./tailwind.js")]);
mix.webpackConfig({
  plugins: [
    new PurgecssPlugin({
      paths: glob.sync([
        path.join(__dirname, "resources/views/**/*.blade.php"),
        path.join(__dirname, "resources/assets/js/**/*.vue")
      ]),
      extractors: [
        {
          extractor: TailwindExtractor,
          extensions: ["html", "js", "php", "vue"]
