```bash
composer test
```

--------------------------------

### Publish GTM settings migration

Source: https://github.com/jeffersongoncalves/laravel-gtm/blob/master/README.md

Publish the settings migration if you need to customize it. This is optional.

```bash
php artisan vendor:publish --tag=gtm-settings-migrations
```

--------------------------------

### Access GTM settings via helper, facade, DI, and app container

Source: https://github.com/jeffersongoncalves/laravel-gtm/blob/master/resources/boost/skills/gtm-development/SKILL.md

Shows four ways to retrieve the GTM ID: using the global helper gtm_settings(), the facade Gtm::gtm_id, dependency injection of GtmSettings, and the app container.

```php
use JeffersonGoncalves\Gtm\Settings\GtmSettings;

// Via global helper
$settings = gtm_settings();
$gtmId = $settings->gtm_id;

// Via facade
$gtmId = \JeffersonGoncalves\Gtm\Facades\Gtm::gtm_id;

// Via dependency injection
public function show(GtmSettings $settings)
{
    return $settings->gtm_id;
}

// Via app container
$settings = app(GtmSettings::class);
```

--------------------------------

### Run Pest tests for GTM package

Source: https://github.com/jeffersongoncalves/laravel-gtm/blob/master/resources/boost/skills/gtm-development/SKILL.md

Execute the test suite using Pest with Orchestra Testbench. Run this command from the package root to verify the GTM head script rendering behavior.

```bash
php vendor/bin/pest
```

--------------------------------

### Define GtmSettings class extending Spatie Settings

Source: https://github.com/jeffersongoncalves/laravel-gtm/blob/master/resources/boost/skills/gtm-development/SKILL.md

The GtmSettings class extends Spatie\LaravelSettings\Settings and defines a public string property 'gtm_id' with a default empty string. The group() method returns 'gtm'.

```php
namespace JeffersonGoncalves\Gtm\Settings;

use Spatie\LaravelSettings\Settings;

class GtmSettings extends Settings
{
    public string $gtm_id = '';

    public static function group(): string
    {
        return 'gtm';
    }
}
```

--------------------------------

  2026_02_20_000000_create_gtm_settings.php  # Settings migration
```

--------------------------------

### Create Filament settings page for GTM

Source: https://github.com/jeffersongoncalves/laravel-gtm/blob/master/resources/boost/skills/gtm-development/SKILL.md

Use this Filament SettingsPage class to manage the GTM container ID in the admin panel. It binds to the GtmSettings class and provides a text input for the GTM ID with a placeholder and max length of 20 characters.

```php
use Filament\Forms\Components\TextInput;
use Filament\Pages\SettingsPage;
use JeffersonGoncalves\Gtm\Settings\GtmSettings;

class ManageGtmSettings extends SettingsPage
{
    protected static string $settings = GtmSettings::class;

    protected static ?string $navigationIcon = 'heroicon-o-code-bracket';

    public function form(Form $form): Form
    {
        return $form->schema([
            TextInput::make('gtm_id')
                ->label('GTM Container ID')
                ->placeholder('GTM-XXXXXXX')
                ->maxLength(20),
        ]);
    }
}
```

--------------------------------

### Update GTM settings via app container

Source: https://github.com/jeffersongoncalves/laravel-gtm/blob/master/resources/boost/skills/gtm-development/SKILL.md

Retrieves the settings instance from the app container, sets the gtm_id property to 'GTM-XXXXXXX', and saves it.

```php
$settings = app(GtmSettings::class);
$settings->gtm_id = 'GTM-XXXXXXX';
$settings->save();
```

--------------------------------

### Pest tests for GTM head script rendering

Source: https://github.com/jeffersongoncalves/laravel-gtm/blob/master/resources/boost/skills/gtm-development/SKILL.md

These Pest tests verify that the GTM head script renders when a GTM ID is set and does not render when the ID is empty. They use the GtmSettings class and assert on the view output.

```php
use JeffersonGoncalves\Gtm\Settings\GtmSettings;

it('renders gtm head script when id is set', function () {
    $settings = app(GtmSettings::class);
    $settings->gtm_id = 'GTM-TEST123';
    $settings->save();

    $view = $this->blade("@include('gtm::head')");

    $view->assertSee('GTM-TEST123');
    $view->assertSee('googletagmanager.com/gtm.js');
});

it('does not render when gtm_id is empty', function () {
    $settings = app(GtmSettings::class);
    $settings->gtm_id = '';
    $settings->save();

    $view = $this->blade("@include('gtm::head')");

    $view->assertDontSee('googletagmanager');
});
```

--------------------------------

### Set GTM ID via helper function

Source: https://github.com/jeffersongoncalves/laravel-gtm/blob/master/README.md

Set the GTM ID at runtime using the gtm_settings() helper function.

```php
$settings = gtm_settings();
$settings->gtm_id = 'GTM-XXXXXX';
$settings->save();
```

--------------------------------

### Read current GTM ID

Source: https://github.com/jeffersongoncalves/laravel-gtm/blob/master/README.md

Read the current GTM ID using three approaches: the gtm_settings() helper, the container, or the Gtm facade.

```php
// Via helper
$gtmId = gtm_settings()->gtm_id;

// Via container
$gtmId = app(\JeffersonGoncalves\Gtm\Settings\GtmSettings::class)->gtm_id;

// Via Facade (resolve the underlying settings instance first)
$gtmId = \JeffersonGoncalves\Gtm\Facades\Gtm::getFacadeRoot()->gtm_id;
```

--------------------------------

### Update GTM ID at runtime

Source: https://github.com/jeffersongoncalves/laravel-gtm/blob/master/README.md

Update the GTM ID at runtime using the gtm_settings() helper.

```php
$settings = gtm_settings();
$settings->gtm_id = 'GTM-NEWID';
$settings->save();
```

--------------------------------

### Include GTM head script

Source: https://github.com/jeffersongoncalves/laravel-gtm/blob/master/README.md

Add the GTM head script inside your <head> tag, as high as possible. The script is only rendered when a valid GTM ID is configured (pattern GTM-XXXXXXX).

```blade
@include('gtm::head')
{{-- or use the Blade directive --}}
@gtmHead
```

--------------------------------

### Set GTM ID via dependency injection

Source: https://github.com/jeffersongoncalves/laravel-gtm/blob/master/README.md

Set the GTM ID at runtime using dependency injection. The GTM ID is stored in the database via spatie/laravel-settings.

```php
use JeffersonGoncalves\Gtm\Settings\GtmSettings;

$settings = app(GtmSettings::class);
$settings->gtm_id = 'GTM-XXXXXX';
$settings->save();
```

--------------------------------

### Include GTM body noscript

Source: https://github.com/jeffersongoncalves/laravel-gtm/blob/master/README.md

Add the GTM body noscript immediately after the opening <body> tag. The script is only rendered when a valid GTM ID is configured.

```blade
@include('gtm::body')
{{-- or use the Blade directive --}}
@gtmBody
```

--------------------------------

### Include gtm::head in Blade layout

Source: https://github.com/jeffersongoncalves/laravel-gtm/blob/master/resources/boost/skills/gtm-development/SKILL.md

Include the GTM head view in your layout's <head> section. The view renders the GTM JavaScript snippet only when the gtm_id setting is non-empty.

```blade
<head>
    @include('gtm::head')
    <!-- other head content -->
</head>
```

```html
<!-- Google Tag Manager -->
<script>(function(w,d,s,l,i){w[l]=w[l]||[];w[l].push({'gtm.start':
    new Date().getTime(),event:'gtm.js'});var f=d.getElementsByTagName(s)[0],
    j=d.createElement(s),dl=l!='dataLayer'?'&l='+l:'';j.async=true;j.src=
    'https://www.googletagmanager.com/gtm.js?id='+i+dl;f.parentNode.insertBefore(j,f);
})(window,document,'script','dataLayer','GTM-XXXXXXX');</script>
<!-- End Google Tag Manager -->
```

--------------------------------

### Include gtm::body in Blade layout

Source: https://github.com/jeffersongoncalves/laravel-gtm/blob/master/resources/boost/skills/gtm-development/SKILL.md

Include the gtm::body view immediately after the <body> tag. It renders the noscript fallback iframe when gtm_id is populated.

```blade
<body>
    @include('gtm::body')
    <!-- page content -->
</body>
```

```html
<!-- Google Tag Manager (noscript) -->
<noscript><iframe src="https://www.googletagmanager.com/ns.html?id=GTM-XXXXXXX"
    height="0" width="0" style="display:none;visibility:hidden"></iframe></noscript>
<!-- End Google Tag Manager (noscript) -->
```
