Laravel Architecture

Laravel Architecture Patterns

Agent Workflow (MANDATORY)

Before ANY implementation, use TeamCreate to spawn 3 agents:

1. fuse-ai-pilot:explore-codebase - Analyze existing architecture
2. fuse-ai-pilot:research-expert - Verify Laravel patterns via Context7
3. mcp__context7__query-docs - Check service container and DI patterns

After implementation, run fuse-ai-pilot:sniper for validation.

Overview

Laravel architecture focuses on clean separation of concerns, dependency injection, and maintainable code organization. This skill covers everything from project structure to production deployment.

When to Use

• Structuring new Laravel projects
• Implementing services, repositories, actions
• Setting up dependency injection
• Configuring development environments
• Deploying to production

Critical Rules

1. Thin controllers - Delegate business logic to services
2. Interfaces in app/Contracts/ - Never alongside implementations
3. DI over facades - Constructor injection for testability
4. Files < 100 lines - Split larger files per SOLID
5. Environment separation - .env never committed

Quick Reference

Service Injection

public function __construct(
    private readonly UserServiceInterface $userService,
) {}

Service Provider Binding

public function register(): void
{
    $this->app->bind(UserServiceInterface::class, UserService::class);
    $this->app->singleton(CacheService::class);
}

Artisan Command

php artisan make:provider CustomServiceProvider
php artisan make:command ProcessOrders

Environment Access

$debug = env('APP_DEBUG', false);
$config = config('app.name');
