Tailwindcss2 @apply directive doesn't work inside vue component

• Laravel Mix Version: “^6.0.6”
• Node Version: 14.4.0
• NPM Version: 6.14.5
• OS: windows

I create a laravel application with jetstream and inertia-vue stack for my new project problem is Tailwindcs version 2 using postCss and it doesn’t support @apply directive inside vue components but inside .css file it works fine I don’t want that because that css file will load my every page I just want short inline utility classes with @apply directive but I can’t, How Can I achieve that.?

inside my vue template

<template>
 <div class="mt-4">
  <label for="hello">Hello</label>
  <input id="hello" class="input"/>
 </div>
</templete>

<style scoped>
    .input {
        @apply bg-gray-200 border h-10
    }
</style>

output inside browser like this

webpack.mix.js

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

mix.js('resources/js/app.js', 'public/js').vue()
    .postCss('resources/css/app.css', 'public/css', [
        require('postcss-import'),
        require('tailwindcss'),
        require('autoprefixer'),
    ])
    .webpackConfig(require('./webpack.config'));

if (mix.inProduction()) {
    mix.version();
}

webpack.config.js

const path = require('path');

module.exports = {
    resolve: {
        alias: {
            '@': path.resolve('resources/js'),
        },
    },
};

tailwind version : “^2.0.1”,

laravel version : 8.x,

jetstream version : 2.x,

inertiajs version: “^0.8.2”

A workaround that can temporarily solve this problem without using laravel-mix-tailwind:

In webpack.mix.js:

const mix = require('laravel-mix')

/*
 |--------------------------------------------------------------------------
 | Mix Asset Management
 |--------------------------------------------------------------------------
 |
 | Mix provides a clean, fluent API for defining some Webpack build steps
 | for your Laravel applications. By default, we are compiling the CSS
 | file for the application as well as bundling up all the JS files.
 |
 */

mix.ts('resources/js/app.ts', 'public/js').vue()
  .postCss('resources/css/app.css', 'public/css')
  .webpackConfig(require('./webpack.config'))
  .sourceMaps()

if (mix.inProduction()) {
  mix.version()
}

In webpack.config.js:

const path = require('path')

module.exports = {
  resolve: {
    alias: {
      '@': path.resolve('resources/js')
    }
  },
  module: {
    rules: [
      {
        test: /\.(postcss)$/,
        use: [
          'vue-style-loader',
          { loader: 'css-loader', options: { importLoaders: 1 } },
          'postcss-loader'
        ]
      }
    ]
  }
}

In postcss.config.js:

module.exports = {
  plugins: [
    require('postcss-import'),
    require('tailwindcss')('./tailwind.config.js'),
    require('autoprefixer')
  ]
}

Now I can use:

<style lang="postcss">
.input-form {
  @apply block w-full mt-1 border-gray-300 rounded-md shadow-sm focus:border-indigo-300 focus:ring focus:ring-indigo-200 focus:ring-opacity-50;
}
</style>

The solution on the fresh install is as simple as putting a bare config file on the root of the project. Source.

// postcss.config.js
module.exports = {
    plugins: {
        tailwindcss: {},
        autoprefixer: {},
    },
}
