Laravel Development Patterns

Production-grade Laravel architecture patterns for scalable, maintainable applications.

When to Use

• Building Laravel web applications or APIs
• Structuring controllers, services, and domain logic
• Working with Eloquent models and relationships
• Designing APIs with resources and pagination
• Adding queues, events, caching, and background jobs

How It Works

• Structure the app around clear boundaries (controllers -> services/actions -> models).
• Use explicit bindings and scoped bindings to keep routing predictable; still enforce authorization for access control.
• Favor typed models, casts, and scopes to keep domain logic consistent.
• Keep IO-heavy work in queues and cache expensive reads.
• Centralize config in config/* and keep environments explicit.

Examples

Project Structure

Use a conventional Laravel layout with clear layer boundaries (HTTP, services/actions, models).

Recommended Layout

├── Exceptions/
├── Http/
│   ├── Controllers/
│   ├── Middleware/
│   ├── Requests/       # Form request validation
│   └── Resources/      # API resources
├── Jobs/
├── Models/
├── Policies/
├── Providers/
├── Services/           # Coordinating domain services
└── Support/

├── api.php
├── web.php
└── console.php

Controllers -> Services -> Actions

Keep controllers thin. Put orchestration in services and single-purpose logic in actions.

final class CreateOrderAction
{
    public function __construct(private OrderRepository $orders) {}

    public function handle(CreateOrderData $data): Order
    {
        return $this->orders->create($data);
    }
}

final class OrdersController extends Controller
{
    public function __construct(private CreateOrderAction $createOrder) {}

    public function store(StoreOrderRequest $request): JsonResponse
    {
        $order = $this->createOrder->handle($request->toDto());

        return response()->json([
            'success' => true,
            'data' => OrderResource::make($order),
            'error' => null,
            'meta' => null,
        ], 201);
    }
}

Routing and Controllers

Prefer route-model binding and resource controllers for clarity.

use Illuminate\Support\Facades\Route;

Route::middleware('auth:sanctum')->group(function () {
    Route::apiResource('projects', ProjectController::class);
});

Route Model Binding (Scoped)

Use scoped bindings to prevent cross-tenant access.

Route::scopeBindings()->group(function () {
    Route::get('/accounts/{account}/projects/{project}', [ProjectController::class, 'show']);
});

Nested Routes and Binding Names

• Keep prefixes and paths consistent to avoid double nesting (e.g., conversation vs conversations).
• Use a single parameter name that matches the bound model (e.g., {conversation} for Conversation).
• Prefer scoped bindings when nesting to enforce parent-child relationships.

use App\Http\Controllers\Api\ConversationController;
use App\Http\Controllers\Api\MessageController;
use Illuminate\Support\Facades\Route;

Route::middleware('auth:sanctum')->prefix('conversations')->group(function () {
    Route::post('/', [ConversationController::class, 'store'])->name('conversations.store');

    Route::scopeBindings()->group(function () {
        Route::get('/{conversation}', [ConversationController::class, 'show'])
            ->name('conversations.show');

        Route::post('/{conversation}/messages', [MessageController::class, 'store'])
            ->name('conversation-messages.store');

        Route::get('/{conversation}/messages/{message}', [MessageController::class, 'show'])
            ->name('conversation-messages.show');
    });
});

If you want a parameter to resolve to a different model class, define explicit binding. For custom binding logic, use Route::bind() or implement resolveRouteBinding() on the model.

use App\Models\AiConversation;
use Illuminate\Support\Facades\Route;

Route::model('conversation', AiConversation::class);

Service Container Bindings

Bind interfaces to implementations in a service provider for clear dependency wiring.

use App\Repositories\EloquentOrderRepository;
use App\Repositories\OrderRepository;
use Illuminate\Support\ServiceProvider;

final class AppServiceProvider extends ServiceProvider
{
    public function register(): void
    {
        $this->app->bind(OrderRepository::class, EloquentOrderRepository::class);
    }
}

Eloquent Model Patterns

Model Configuration

final class Project extends Model
{
    use HasFac
