Klass for Laravel
=================

[](#klass-for-laravel)

Klass extracts your dynamic classes in your Blade components to a file that PurgeCSS can process.

Installation
------------

[](#installation)

> Requires [PHP 8.0.0+](https://php.net/releases)

You can install the package via composer:

```
composer require felixdorn/klass
```

Usage
-----

[](#usage)

```
// app/View/Components/Button.php
class Button extends Component {
    public string $color;

    public function __construct(string $color = 'blue') {
        $this->color = $color;
    }

    public function render() {
        return view('components.button');
    }
}
```

```

    {{ $slot }}

```

```

```

```
php artisan klass:extract
```

```
// storage/framework/extracted-classes.txt
bg-red-500 bg-blue-500

```

You can now add that file to PurgeCSS, or a similar tool to include those classes in your final CSS build.

Configuration
-------------

[](#configuration)

You can publish the config file with:

```
php artisan vendor:publish --provider="Felix\\Klass\\KlassServiceProvider" --tag="klass-config"
```

This is the contents of the published config file:

```
return [
    'components_paths' => [
        resource_path('views/components'),
        base_path('vendor'),
    ],

    'views_paths' => [
        resource_path('views'),
    ],

    'output' => base_path('storage/framework/extracted-classes.txt'),
];
```

Tailwind & JIT compilation
------------------------------

[](#tailwind--jit-compilation)

Klass works well with the old Tailwind workflow aka use a build with a ton of classes in development and then remove all of the unused classes in production. However, recently, Tailwind got a JIT compiler to have a production-like css in development.

Klass could work quite easily with the JIT compiler. At compile time, `php artisan klass:extract` should be called but I have yet to figure out how to do that in a smart way.

Livewire
--------

[](#livewire)

Blade components used in a Livewire component are analyzed. However, we do not support Livewire components in itself. I have no plans to support it before traditional Blade components edge cases are resolved. I'd merge a PR adding support for it, if you feel like contributing.

Testing
-------

[](#testing)

```
composer test
```
