@apply not working inside Vue component in Laravel Mix

Question

I am using Tailwind CSS in Laravel with VueJS component like this.

<template>

</template>

<script>

</script>

<style lang="postcss" scoped>

    .day-disabled {

        @apply text-gray-400;
    }

</style>

However it is complaining that

Module parse failed: Unexpected token (685:0)
File was processed with these loaders:
 * ./node_modules/vue-loader/lib/index.js
You may need an additional loader to handle the result of these loaders.

> .day-disabled {
|
|     @apply text-gray-400;

Is there anyway to use @apply directive in VueJS component using Laravel Mix. This is my webpack.mix.js

const mix = require('laravel-mix');
mix.options({ extractVueStyles: true})
   .js('resources/js/app.js', 'public/js')
   .postCss('resources/css/app.css', 'public/css', [
       require('postcss-import'),
       require('tailwindcss'),
       require('postcss-nested'),
       require('postcss-custom-properties'),
       require('autoprefixer')
   ]);

Is there anyway to resolve this issue.

It seems this may be a bug in Laravel Mix, see this issue.

Try adding the following to your Mix config (source):

.webpackConfig({
  module: {
    rules: [
      {
        test: /\.(postcss)$/,
        use: [
          'vue-style-loader',
          { loader: 'css-loader', options: { importLoaders: 1 } },
          'postcss-loader'
        ]
      }
    ],
  },
})
