# Filament v5 Plugin Development Standards

## Requirements
- PHP 8.2+
- Laravel 11.28+
- Livewire 4.0+
- Tailwind CSS 4.0+
- filament/filament: ^5.0

## Namespaces (Filament 5.x)
- Forms: `Filament\Forms\Components\*` (TextInput, Select, Toggle, etc.)
- Tables: `Filament\Tables\Columns\*` (TextColumn, IconColumn, etc.)
- Filters: `Filament\Tables\Filters\*`
- Actions: `Filament\Actions\*` (EditAction, DeleteAction, BulkActionGroup, etc.)
- Schema: `Filament\Schemas\Schema`
- Plugin Interface: `Filament\Contracts\Plugin`
- Panel: `Filament\Panel`
- Widgets: `Filament\Widgets\Widget`, `Filament\Widgets\StatsOverviewWidget`
- Resources: `Filament\Resources\Resource`
- Pages: `Filament\Resources\Pages\*` (ListRecords, CreateRecord, EditRecord, ViewRecord)

## Resource Structure (v5 Pattern)
```
Resources/
  CustomerResource.php
  Pages/
    CreateCustomer.php
    EditCustomer.php
    ListCustomers.php
  Schemas/
    CustomerForm.php
  Tables/
    CustomersTable.php
```

## Plugin Class Pattern
```php
use Filament\Contracts\Plugin;
use Filament\Panel;

class MyPlugin implements Plugin
{
    public static function make(): static
    {
        return app(static::class);
    }

    public static function get(): static
    {
        return filament(app(static::class)->getId());
    }

    public function getId(): string
    {
        return 'my-plugin';
    }

    public function register(Panel $panel): void
    {
        $panel->resources([...])->pages([...])->widgets([...]);
    }

    public function boot(Panel $panel): void {}
}
```

## Service Provider Pattern
- Extend `Spatie\LaravelPackageTools\PackageServiceProvider`
- Register views, translations, migrations in `configurePackage()`
- Register assets in `packageBooted()`
- Use `$package->name()->hasViews()->hasTranslations()->hasMigrations()->hasRoutes()`

## Code Style
- Use PHP 8.2 features (enums, readonly, named arguments, fibers)
- Follow Laravel Pint formatting
- Use strict types in all files
- Prefix all database tables with `crm_`
- Prefix all config keys with `refineder-crm`
