My current webpack.mix.js configuration is:
mix.js('resources/js/app.js', 'public/js')
.postCss('resources/css/app.css', 'public/css', [
require('postcss-import'),
require('tailwindcss'),
]).extract();
If I have another CSS, let's say 'plugin-1.css', how can I merge both so that I get an output of one app.css?
I tried ['resources/css/app.css', 'plugin-1.css'] but that's not an option.
