Laravel Operations
Facts verified as of 2026-07.
Authoritative reference for Laravel 11+ development: architecture decisions, Eloquent patterns, authentication strategies, queue configuration, and testing approaches.
Architecture Decision Tree
What type of application?
│
├─ Full-stack web (HTML responses)
│ ├─ Simple CRUD, small team → Monolith (Blade + Eloquent directly)
│ │ └─ Use action classes for business logic over 20 lines
│ ├─ Rich interactivity needed → Livewire (server-driven reactivity)
│ │ └─ Add Alpine.js for client-side micro-interactions
│ └─ SPA-like feel, React/Vue team → Inertia.js
│ └─ Keep server-side routing, dump client-side routing overhead
│
├─ API backend (JSON responses)
│ ├─ Single consumer (mobile/SPA) → API-only with Sanctum SPA auth
│ ├─ Multiple consumers / public → RESTful API with token auth
│ └─ Complex graph queries → Consider GraphQL (lighthouse-php/lighthouse)
│
├─ Large team / complex domain
│ ├─ Domain-driven → Modular monolith (app/Modules/{Domain}/)
│ │ ├─ Each module: Models, Actions, Events, Jobs, Http/
│ │ └─ Shared: app/Shared/ for cross-cutting concerns
│ └─ Independent deployability needed → Microservices
│ └─ Use Laravel Octane for high-throughput services
│
└─ What business logic pattern?
├─ Simple CRUD, < 20 lines → Direct Eloquent in controller
├─ Reusable operation (create order, send invoice) → Action class
│ └─ Single public handle() or execute() method
├─ Complex queries, multiple data sources → Repository pattern
│ └─ Interface + Eloquent implementation (enables swapping)
└─ Cross-cutting operations (audit, caching) → Service class
└─ Inject via constructor, bind in ServiceProvider
Action Class vs Repository vs Service
| Pattern |
Use When |
Example |
| Action class |
Single, reusable business operation |
CreateOrderAction, SendInvoiceAction |
| Repository |
Abstract data access, multiple sources |
OrderRepository with EloquentOrderRepository |
| Service |
Orchestrate multiple actions/repos |
OrderService combining payment + inventory |
| Direct Eloquent |
Simple CRUD, < 5 lines in controller |
User::create($data) |

Polymorphic pivot |
Eager Loading
// Prevent N+1: always eager load in controllers
$posts = Post::with(['author', 'comments.author', 'tags'])->paginate(15);
// Conditional eager loading (load after retrieval)
$user->load('posts.comments');
$user->loadMissing('posts'); // only if not already loaded
// Eager load counts (no SELECT *)
$posts = Post::withCount('comments')->get();
// Constrained eager loading
$posts = Post::with(['comments' => fn($q) => $q->approved()->latest()])->get();
Query Scopes
// Local scope (reusable query constraint)
public function scopeActive(Builder $query): void
{
$query->where('status', 'active');
}
// Usage: User::active()->get()
// Dynamic scope
public function scopeOfType(Builder $query, string $type): void
{
$query->where('type', $type);
}
// Usage: User::ofType('admin')->get()
Mass Assignment
// Fillable (allowlist - preferred)
protected $fillable = ['name', 'email', 'password'];
// Guarded (denylist - use [] only if you trust all input)
protected $guarded = ['id', 'is_admin'];
// Never set guarded = [] in production code

Authentication Decision Tree
What do you need?
│
├─ SPA (Vue/React) + Laravel API backend
│ └─ Sanctum SPA authentication
│ ├─ Cookie-based (same domain or subdomain)
│ ├─ Csrf-cookie endpoint: GET /sanctum/csrf-cookie
│ └─ No tokens in localStorage (XSS safe)
│
├─ Mobile app or third-party API consumers
│ └─ Sanctum API tokens (Bearer tokens)
│ ├─ createToken($name, $abilities)
│ ├─ Token abilities for fine-grained control
│ └─ Token expiration with token:prune schedule
│
├─ Traditional web app (server-rendered)
│ ├─ Just need auth pages quickly → Breeze
│ │ ├─ Minimal, educational, Blade or Inertia stack
│ │ └─ Install: composer require laravel/breeze --dev
│ ├─ Need teams, 2FA, profile management → Jetstream
│ │ ├─ Livewire or Inertia stack
│ │ └─ Install: composer require laravel/jetstream
│ └─ Need headless auth (API + custom UI) → Fortify
│ ├─ Actions in app/Actions/Fortify/
│ └─ Customize: CreateNewUser, UpdateUserPassword
│
└─ Custom / enterprise
├─ LDAP/SAML → socialiteproviders/saml2
├─ OAuth social login → laravel/socialite
└─ Custom guard → Implement Guard + UserProvider contracts
Sanctum Quick Setup
// config/sanctum.php - stateful domains for SPA
'stateful' => explode(',', env('SANCTUM_STATEFUL_DOMAINS', 'localhost')),
// API token creation
$token = $user->createToken('mobile-app', ['orders:read', 'orders:write']);
return ['token' => $token->plainTextToken];
// Check token ability
Route::get('/orders', function (Request $request) {
$request->user()->tokenCan('orders:read'); // bool
});
// Protect routes
Route::middleware('auth:sanctum')->group(function () {
// authenticated routes
});
Queue Decision Tree
Queue driver selection:
│
├─ Development / testing
│ └─ sync driver (executes immediately, no worker needed)
│ QUEUE_CONNECTION=sync
│
├─ Small app, no Redis available
│ └─ database driver
│ ├─ php artisan queue:table && migrate
│ ├─ Works fine for < 100 jobs/min
│ └─ QUEUE_CONNECTION=database
│
├─ Medium-high throughput, self-hosted
│ └─ Redis driver (via predis or phpredis)
│ ├─ QUEUE_CONNECTION=redis
│ ├─ Laravel Horizon for monitoring
│ └─ Supports priorities, pausing, metrics
│
└─ AWS infrastructure / massive scale
└─ SQS driver
├─ QUEUE_CONNECTION=sqs
├─ Managed, auto-scaling
└─ Use with Laravel Vapor for serverless
Job Patterns
// Basic job dispatch
ProcessPayment::dispatch($order);
ProcessPayment::dispatch($order)->onQueue('payments')->delay(now()->addMinutes(5));
// Chaining (sequential)
Bus::chain([
new ProcessPayment($order),
new SendInvoice($order),
new UpdateInventory($order),
])->dispatch();
// Batching (parallel + callback)
$batch = Bus::batch([
new ImportRow($row1),
new ImportRow($row2),
new ImportRow($row3),
])->then(fn(Batch $batch) => ImportComplete::dispatch())
->catch(fn(Batch $batch, Throwable $e) => Log::error($e))
->dispatch();
// Rate limiting (throttle to 5 per minute)
public function middleware(): array
{
return [new RateLimited('payments')];
}
// Unique jobs (prevent duplicate processing)
use Illuminate\Contracts\Queue\ShouldBeUnique;
class ProcessPayment implements ShouldQueue, ShouldBeUnique
{
public string $uniqueId => $this->order->id;
public int $uniqueFor = 3600; // seconds
}
// Retry configuration
public int $tries = 3;
public int $backoff = 60; // seconds between retries
public function retryUntil(): DateTime
{
return now()->addHours(24);
}
Task Scheduling
// routes/console.php (Laravel 11+)
Schedule::job(SendDailyReport::class)->dailyAt('08:00')->timezone('America/New_York');
Schedule::command('backup:run')->daily()->runInBackground()->emailOutputOnFailure('ops@app.com');
Schedule::call(fn() => Cache::flush())->weekly()->sundays()->at('00:00');
// Prevent overlap (long-running tasks)
Schedule::job(ProcessImport::class)->everyFiveMinutes()->withoutOverlapping();
// Run on one server only (requires Redis/database cache driver)
Schedule::job(SendNewsletters::class)->daily()->onOneServer();
Testing Quick Reference
Test Types
| Type |
Class extends |
Database |
Purpose |
| Feature test |
Tests\TestCase |
Yes (with trait) |
HTTP endpoints, full stack |
| Unit test |
PHPUnit\Framework\TestCase |
No |
Pure logic, no app boot |
| Browser test |
Laravel\Dusk\TestCase |
Yes |
Real browser via ChromeDriver |
Database Traits
use Illuminate\Foundation\Testing\RefreshDatabase; // migrate fresh each test (slower)
use Illuminate\Foundation\Testing\DatabaseTransactions; // rollback each test (faster)
Pest Syntax (preferred in Laravel 11+)
describe('User authentication', function () {
beforeEach(function () {
$this->user = User::factory()->create();
});
it('allows login with valid credentials', function () {
$response = $this->post('/login', [
'email' => $this->user->email,
'password' => 'password',
]);
$response->assertRedirect('/dashboard');
$this->assertAuthenticatedAs($this->user);
});
it('rejects invalid credentials')->todo();
});
Common Assertions
// HTTP response
$response->assertStatus(200);
$response->assertOk(); // 200
$response->assertCreated(); // 201
$response->assertNoContent(); // 204
$response->assertUnauthorized(); // 401
$response->assertForbidden(); // 403
$response->assertNotFound(); // 404
$response->assertRedirect('/home');
// JSON responses
$response->assertJson(['status' => 'ok']);
$response->assertJsonPath('data.email', 'user@example.com');
$response->assertJsonCount(3, 'data');
$response->assertJsonStructure(['data' => ['id', 'name', 'email']]);
$response->assertJsonMissing(['password']);
// Database
$this->assertDatabaseHas('users', ['email' => 'user@example.com']);
$this->assertDatabaseMissing('users', ['email' => 'deleted@example.com']);
$this->assertDatabaseCount('posts', 5);
$this->assertSoftDeleted('posts', ['id' => $post->id]);
Common Gotchas
| Gotcha |
Why |
Fix |
| N+1 queries on relationships |
Eloquent lazy-loads by default |
Use with() eager loading; enable Model::preventLazyLoading() in AppServiceProvider during development |
| Mass assignment vulnerability |
$fillable = [] accepts all |
Always define $fillable; never use $guarded = [] in production |
created_at not updating on update() |
Only updated_at auto-sets |
Use $model->touch() or timestamps = true (default) |
| Queue job fails on model serialization |
Model state may change between dispatch and processing |
Use SerializesModels trait; re-fetch from DB in handle() if needed |
| Timezone mismatch in scheduled tasks |
Server tz != app tz |
Set APP_TIMEZONE in .env; use ->timezone() on schedule entries |
| Middleware order matters |
Auth middleware must run before policies |
Global → route group → route. Auth before throttle check or vice versa changes 401 vs 429 |
| Route model binding skips soft-deleted records |
RouteServiceProvider ignores trashed() |
Extend binding: Route::bind('post', fn($id) => Post::withTrashed()->findOrFail($id)) |
| Service container binding not auto-resolved |
Interface not bound to implementation |
Register in AppServiceProvider::register(): $this->app->bind(Interface::class, Implementation::class) |
| Migration foreign key order |
Must create referenced table first |
Run migrate:fresh to verify; use Schema::disableForeignKeyConstraints() in tests |
| CSRF protection blocks API routes |
VerifyCsrfToken runs on all web routes |
Register API routes in routes/api.php (uses api middleware group without CSRF) |
env() returns null after caching |
config:cache bakes env values |
Always access env via config() helper in app code; only use env() in config/ files |
Blade @stack renders in wrong order |
@push must appear after @stack in execution |
Use @prepend for scripts that must appear first |
| Event listener not firing |
Listener not registered or discovered |
Check EventServiceProvider::$listen; or enable Event::discover() in Laravel 11 |

enable `Model::preventLazyLoading()` in AppServiceProvider during development |386| Mass assignment vulnerability | `$fillable = []` accepts all | Always define `$fillable`; never use `$guarded = []` in production |387| `created_at` not updating on `update()` | Only `updated_at` auto-sets | Use `$model->touch()` or `timestamps = true` (default) |388| Queue job fails on model serialization | Model state may change between dispatch and processing | Use `SerializesModels` trait; re-fetch from DB in `handle()` if needed |389| Timezone mismatch in scheduled tasks | Server tz != app tz | Set `APP_TIMEZONE` in `.env`; use `->timezone()` on schedule entries |390| Middleware order matters | Auth middleware must run before policies | Global → route group → route. Auth before throttle check or vice versa changes 401 vs 429 |391| Route model binding skips soft-deleted records | `RouteServiceProvider` ignores `trashed()` | Extend binding: `Route::bind('post', fn($id) => Post::withTrashed()->findOrFail($id))` |392| Service container binding not auto-resolved | Interface not bound to implementation | Register in `AppServiceProvider::register()`: `$this->app->bind(Interface::class, Implementation::class)` |393| Migration foreign key order | Must create referenced table first | Run `migrate:fresh` to verify; use `Schema::disableForeignKeyConstraints()` in tests |394| CSRF protection blocks API routes | `VerifyCsrfToken` runs on all web routes | Register API routes in `routes/api.php` (uses `api` middleware group without CSRF) |395| `env()` returns null after caching | `config:cache` bakes env values | Always access env via `config()` helper in app code; only use `env()` in `config/` files |396| Blade `@stack` renders in wrong order | `@push` must appear after `@stack` in execution | Use `@prepend` for scripts that must appear first |397| Event listener not firing | Listener not registered or discovered | Check `EventServiceProvider::$listen`; or enable `Event::discover()` in Laravel 11 |398399---400401## Reference Files402403| File | Contents |404|------|---------|405| `references/eloquent-queries.md` | Deep-dive: relationships, query builder, scopes, accessors, mutators, events, soft deletes, pagination, performance, collections, factories |406| `references/architecture.md` | Service container, providers, facades, middleware, events, notifications, jobs, scheduling, Blade components, Livewire, Inertia |407| `references/testing-auth.md` | PHPUnit/Pest setup, HTTP tests, database testing, fakes, Sanctum, Fortify, policies, form requests, Dusk |408409---410411## See Also412413- `sql-ops` - Query optimization, indexing strategy, raw SQL patterns414- `postgres-ops` - PostgreSQL-specific features, JSON columns, full-text search415- `testing-ops` - General testing philosophy, TDD, CI integration416- `docker-ops` - Containerizing Laravel apps, Docker Compose, production setup417418### Key External Resources419420- [Laravel 11 Documentation](https://laravel.com/docs/11.x)421- [Pest PHP](https://pestphp.com/)422- [Laravel Horizon](https://laravel.com/docs/11.x/horizon) - Queue monitoring423- [Laravel Telescope](https://laravel.com/docs/11.x/telescope) - Local debugging and request/query monitoring424- [Laravel Octane](https://laravel.com/docs/11.x/octane) - High-performance serving425- [Laravel Forge](https://forge.laravel.com/) - Server management426- [Laravel Vapor](https://vapor.laravel.com/) - Serverless deployment
