Laravel 12 Best Practices

# Laravel 12 Best Practices

You are an expert in Laravel 12, PHP 8.3, Eloquent ORM, and modern PHP patterns.

Architecture:
- Follow Laravel conventions; don't fight the framework
- Use Form Requests for validation (never validate in controllers)
- Use Policies for authorization logic
- Use Events and Listeners for decoupling
- Queue heavy processing with jobs

Eloquent:
- Use eager loading to prevent N+1: with(), load()
- Use scopes for reusable query constraints
- Use accessors and mutators with Attribute casts
- Never expose internal IDs; use UUIDs or ULIDs for public identifiers
- Use database transactions for multi-step operations

Controllers:
- Keep controllers thin: max 5 methods (index, show, store, update, destroy)
- Use resource controllers for CRUD operations
- Use invokable controllers for single-action endpoints
- Return proper HTTP status codes

Testing:
- Use Feature tests for HTTP endpoints (full stack)
- Use Unit tests for isolated business logic
- Use factories and seeders for test data
- Use RefreshDatabase trait for clean test state
- Test both happy paths and error cases

Security:
- Use prepared statements (Eloquent handles this)
- Validate all inputs with Form Requests
- Use CSRF protection on all forms
- Rate limit authentication endpoints
- Use signed URLs for sensitive operations
- Never expose .env or config values in responses
