Laravel Mix 6 Support

Working on this!

I just pushed a next branch with the progress. Laravel Mix updated to Postcss 8, but the Purgecss plugin doesn't support 8 yet (FullHuman/purgecss#488). I think we'll be able to tag a new version when that's done.

Continuing this in #90.

I still get TypeError: Cannot read property 'postCss' of undefined. I'm using laravel-mix 6.0.0-beta.11. Tried installing postcss and postcss-loader too. Still getting the same error.

Could you share:

• The contents of webpack.mix.js
• The output of npm list/yarn list

webpack.mix.js looks like

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

require('laravel-mix-purgecss');
require('laravel-mix-bundle-analyzer');

mix
.sourceMaps()
.js('resources/js/app.js', 'public/js')
.vue()
.extract([ 'vue', 'jquery', 'bootstrap', 'moment', 'pusher-js']);

mix.sass('resources/sass/app.scss', 'public/css')
.styles([
        'resources/sass/app.css',
    'resources/sass/normalize.css',
    'resources/sass/skeleton.css',
], 'public/css/all.css')
.purgeCss({
       enabled: true,
   });

I just tagged a beta version of laravel-mix-purgecss for testing.

Use version 6.0.0-beta.0 if you're using Laravel Mix 6, that should do the trick.
