gistfile1.txt

const mix = require('laravel-mix');
const tailwindcss = require('tailwindcss');
require('laravel-mix-purgecss');

mix.setPublicPath('./web')
    .postCss('src/css/main.css', 'css')
    .options({
        postCss: [tailwindcss('tailwind.config.js'), require('autoprefixer')],
        processCssUrls: false,
    })

    .js([
        'src/js/main.js',
    ], 'js')

    .browserSync({
    proxy: 'http://example.test',
    browser: 'firefox',
    files: ['templates/*.twig','templates/**/*.twig','web/css/*.css','web/js/*.js']
});

mix.disableSuccessNotifications();


if (mix.inProduction()) {
    mix.purgeCss({
        enabled: true,
        globs: [
            path.join(__dirname, 'templates/*.twig'),
            path.join(__dirname, 'templates/**/*.twig'),
            path.join(__dirname, 'templates/**/**/*.twig'),
            path.join(__dirname, 'src/js/*.js'),
        ],
        extensions: ['html', 'js', 'twig', 'vue'],
        whitelist: [

        ],
        folders: ['src', 'templates'],
    })
        .version();
};

I am using Twigpack https://plugins.craftcms.com/twigpack

Let me know if you can't get it to work.

Wow, this is cool! Thanks.
