# Controller Features
- Use invokable controllers for single actions. Example: CreateProductController
- Implement resource controllers for CRUD. Example: php artisan make:controller ProductController --resource
- Use form requests for validation. Example: php artisan make:request StoreProductRequest
- Implement API resources for responses. Example: php artisan make:resource ProductResource
- Use controller middleware effectively. Example: $this->middleware('auth')->except(['index', 'show'])

# Service Pattern
- Implement service classes for business logic. Example:
```php
class ProductService
{
 public function __construct(
 private readonly ProductRepository $repository,
 private readonly ImageService $imageService
 ) {}

 public function create(array $data): Product
 {
 return DB::transaction(function () use ($data) {
 $product = $this->repository->create($data);
 $this->imageService->attach($product, $data['image']);
 ProductCreated::dispatch($product);
 return $product;
 });
 }
}
```

# Repository Pattern
- Use repositories for data access. Example:
```php
class ProductRepository
{
 public function findByCategory(string $category): Collection
 {
 return Product::query()
 ->whereBelongsTo(Category::findBySlug($category))
 ->with(['variants', 'media'])
 ->cached()
 ->get();
 }
}
```

# Model Features
- Use Laravel's new model features. Example:
```php
class Product extends Model
{
 use HasUuid, SoftDeletes, HasFactory;
 
 protected $casts = [
 'price' => Price::class,
 'status' => ProductStatus::class,
 'settings' => AsArrayObject::class
 ];
 
 public function scopeActive($query): void
 {
 $query->where('status', ProductStatus::Active);
 }
}
```

# Event System
- Implement event listeners effectively. Example:
```php
class ProductEventSubscriber
{
 public function handleProductCreated(ProductCreated $event): void
 {
 Cache::tags(['products'])->flush();
 Notification::send($admins, new ProductCreatedNotification($event->product));
 }
 
 public function subscribe(Dispatcher $events): array
 {
 return [
 ProductCreated::class => 'handleProductCreated'
 ];
 }
}
```

# Job Queue Features
- Use job batching for complex operations. Example:
```php
$batch = Bus::batch([
 new ProcessProductImages($product),
 new UpdateSearchIndex($product),
 new NotifySubscribers($product)
])->then(function (Batch $batch) {
 Log::info('All jobs completed');
})->dispatch();
```

# Cache Features
- Implement cache tags and invalidation. Example:
```php
Cache::tags(['products', "product-{$id}"])
 ->remember("product-{$id}", 3600, fn () => 
 Product::with('category')->findOrFail($id)
 );
```

# API Features
- Use API resources with conditional attributes. Example:
```php
class ProductResource extends JsonResource
{
 public function toArray(Request $request): array
 {
 return [
 'id' => $this->id,
 'name' => $this->name,
 $this->mergeWhen($request->user()?->isAdmin(), [
 'cost' => $this->cost,
 'margin' => $this->margin
 ])
 ];
 }
}
```

# Testing Features
- Use Pest for testing with datasets. Example:
```php
test('it calculates product margins')
 ->with([
 [100, 150, 50],
 [200, 300, 100]
 ])
 ->expect(fn (int $cost, int $price, int $margin) => 
 Product::calculateMargin($cost, $price)
 )->toBe(fn (int $margin) => $margin);
```

# Performance Features
- Use lazy loading for collections. Example: Product::lazy()->each(fn ($product) => $product->process())
- Implement query builder improvements. Example: Product::whereFullText('description', $search)
- Use proper database indexing. Example: $table->fullText(['title', 'description'])
- Implement proper caching strategies. Example: Cache::tags(['products'])->remember()
- Use proper eager loading. Example: Product::with('category', 'tags')->get()

# SEO Features
- Use sitemap generation. Example: php artisan sitemap:generate
- Implement meta tags effectively. Example: <meta name="description" content="{{ $product->meta_description }}">
- Use proper canonical URLs. Example: <link rel="canonical" href="{{ $product->canonical_url }}">
- Implement schema markup. Example: @json(['@type' => 'Product', 'name' => $product->name])
- Use proper robots.txt management
