PurgeCSS wrapper for Laravel Mix

This package adds a purgeCss option to Laravel Mix, which installs PurgeCSS for you with a set of sensible defaults for Laravel applications.

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

// ...

mix.js('resources/js/app.js', 'public/js')
   .sass('resources/sass/app.scss', 'public/css')
   .purgeCss();

Installation

Before you get started, make sure you're using laravel-mix version 5.0.0 or higher.

You can install the package with yarn or npm:

yarn add laravel-mix-purgecss --dev

npm install laravel-mix-purgecss --save-dev

Then install the extension by requiring the module in your Mix configuration.

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

// ...

PurgeCSS can be enabled by calling .purgeCss() in your Mix chain.

mix.js('resources/js/app.js', 'public/js')
   .sass('resources/sass/app.scss', 'public/css')
   .purgeCss();

By default, PurgeCSS only works when building assets for production. You can override this behaviour by specifying the enabled option.

mix.js('resources/js/app.js', 'public/js')
   .sass('resources/sass/app.scss', 'public/css')
   .purgeCss({
       enabled: true,
   });

Important notice for mix.postCss or postcss.config.js users

When you use mix.postCss() or a seperate postcss.config.js file, Mix overrides all other PostCSS plugins, including the PurgeCSS instance added by this plugin.

To work around this issue, either:

1) Include your PostCSS plugins with mix.options()

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

  mix.js('resources/js/app.js', 'public/js')
-     .postCss('resources/sass/app.css', 'public/css', [
-         require('tailwindcss')(),
-     ])
+     .postCss('resources/sass/app.css', 'public/css')
+     .options({
+         postCss: [require('tailwindcss')]
+     })
      .purgeCss();

2) Don't use this package, and use postcss-purgecss-laravel instead

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

  mix.js('resources/js/app.js', 'public/js')
      .postCss('resources/sass/app.css', 'public/css', [
          require('tailwindcss')(),
+         require('postcss-purgecss-laravel')({ /* ... */ }),
      ])
      .purgeCss();

PurgeCSS customization

Custom options can be passed when calling PurgeCSS if necessary. Visit PurgeCSS' docs to learn more about the available options.

mix.js('resources/js/app.js', 'public/js')
   .sass('resources/sass/app.scss', 'public/css')
   .purgeCss({
       content: [path.join(__dirname, 'vendor/spatie/menu/**/*.php')],
       safelist: { deep: [/hljs/] },
   });

Passing options will override the package defaults. If you want to extend the package defaults, wrap them in an extend object.

mix.js('resources/js/app.js', 'public/js')
   .sass('resources/sass/app.scss', 'public/css')
   .purgeCss({
       extend: {
           content: [path.join(__dirname, 'vendor/spatie/menu/**/*.php')],
           safelist: { deep: [/hljs/] },
       },
   });

This package uses postcss-purgecss-laravel under the hood, which has the following defaults:

const defaultConfig = {
    content: [
        "app/**/*.php",
        "resources/**/*.html",
        "resources/**/*.js",
        "resources/**/*.jsx",
        "resources/**/*.ts",
        "resources/**/*.tsx",
        "resources/**/*.php",
        "resources/**/*.vue",
        "resources/**/*.twig",
    ],
    defaultExtractor: (content) => content.match(/[\w-/.:]+(?<!:)/g) || [],
    safelist: { standard: [/-active$/, /-enter$/, /-leave-to$/, /show$/] },
}
