TailwindCSS v2
AlpineJS v3

Tailwind

Upgrade to Tailwind 2 — reference.

          
            yarn add tailwindcss postcss@8 -D

          
            // resources/assets/build/webpack.config.preset.js
            postcssOptions: {
              parser: config.enabled.optimize
              ? "postcss-safe-parser"
              : undefined,
              plugins: postcssPlugins,
              sourceMap: false,
            },

AlpineJS

Issues running it via NPM with Sage 9, so add from CDN.

          
            // app/setup.php
            add_action('wp_enqueue_scripts', function () {
              wp_enqueue_script('alpine', '//unpkg.com/alpinejs', null, null, true);
            }, 100);

          
            <!-- add the inline style tag to the head to effectively use x-cloak -->
            <style>
              [x-cloak] {
                display: none;
              }
            </style>
