Your Approach

• Convention Over Configuration: Follow Laravel's established conventions and "The Laravel Way" for consistency and maintainability
• Eloquent First: Use Eloquent ORM for database interactions unless raw queries provide clear performance benefits
• Artisan-Powered Workflow: Leverage Artisan commands for code generation, migrations, testing, and deployment tasks
• Test-Driven Development: Encourage feature and unit tests using PHPUnit to ensure code quality and prevent regressions
• Single Responsibility: Apply SOLID principles, particularly single responsibility, to controllers, models, and services
• Service Container Mastery: Use dependency injection and the service container for loose coupling and testability
• Security First: Apply Laravel's built-in security features including CSRF protection, input validation, and query parameter binding
• RESTful Design: Follow REST conventions for API endpoints and resource controllers

Guidelines

Project Structure

• Follow PSR-4 autoloading with App\\ namespace in app/ directory
• Organize controllers in app/Http/Controllers/ with resource controller pattern
• Place models in app/Models/ with clear relationships and business logic
• Use form requests in app/Http/Requests/ for validation logic
• Create service classes in app/Services/ for complex business logic
• Place reusable helpers in dedicated helper files or service classes

Artisan Commands

• Generate controllers: php artisan make:controller UserController --resource
• Create models with migration: php artisan make:model Post -m
• Generate complete resources: php artisan make:model Post -mcr (migration, controller, resource)
• Run migrations: php artisan migrate
• Create seeders: php artisan make:seeder UserSeeder
• Clear caches: php artisan optimize:clear
• Run tests: php artisan test or vendor/bin/phpunit

Eloquent Best Practices

• Define relationships clearly: hasMany, belongsTo, belongsToMany, hasOne, morphMany
• Use query scopes for reusable query logic: scopeActive, scopePublished
• Implement accessors/mutators using attributes: protected function firstName(): Attribute
• Enable mass assignment protection with $fillable or $guarded
• Use eager loading to prevent N+1 queries: User::with('posts')->get()
• Apply database indexes for frequently queried columns
• Use model events and observers for lifecycle hooks

Route Conventions

• Use resource routes for CRUD operations: Route::resource('posts', PostController::class)
• Apply route groups for shared middleware and prefixes
• Use route model binding for automatic model resolution
• Define API routes in routes/api.php with api middleware group
• Apply named routes for easier URL generation: route('posts.show', $post)
• Use route caching in production: php artisan route:cache

Validation

• Create form request classes for complex validation: php artisan make:request StorePostRequest
• Use validation rules: 'email' => 'required|email|unique:users'
• Implement custom validation rules when needed
• Return clear validation error messages
• Validate at the controller level for simple cases

Database & Migrations

• Use migrations for all schema changes: php artisan make:migration create_posts_table
• Define foreign keys with cascading deletes when appropriate
• Create factories for testing and seeding: php artisan make:factory PostFactory
• Use seeders for initial data: php artisan db:seed
• Apply database transactions for atomic operations
• Use soft deletes when data retention is needed: use SoftDeletes;

Testing

• Write feature tests for HTTP endpoints in tests/Feature/
• Create unit tests for business logic in tests/Unit/
• Use database factories and seeders for test data
• Apply database migrations and refreshing: use RefreshDatabase;
• Test validation rules, authorization policies, and edge cases
• Run tests before commits: php artisan test --parallel
• Use Pest for expressive testing syntax (optional)

API Development

• Create API resource classes: php artisan make:resource PostResource
• Use API resource collections for lists: PostResource::collection($posts)
• Apply versioning through route prefixes: Route::prefix('v1')->group()
• Implement rate limiting: ->middleware('throttle:60,1')
• Return consistent JSON responses with proper HTTP status codes
• Use API tokens or Sanctum for authentication

Security Practices

• Always use CSRF protection for POST/PUT/DELETE routes
• Apply authorization policies: php artisan make:policy PostPolicy
• Validate and sanitize all user input
• Use parameterized queries (Eloquent handles this automatically)
• Apply the auth middleware to protected routes
• Hash passwords with bcrypt: Hash::make($password)
• Implement rate limiting on authentication endpoints

Performance Optimization

• Use eager loading to prevent N+1 queries
• Apply query result caching for expensive queries
• Use queue workers for long-running tasks: php artisan make:job ProcessPodcast
• Implement database indexes on frequently queried columns
• Apply route and config caching in production
• Use Laravel Octane for extreme performance needs
• Monitor with Laravel Telescope in development

Environment Configuration

• Use .env files for environment-specific configuration
• Access config values: config('app.name')
• Cache configuration in production: php artisan config:cache
• Never commit .env files to version control
• Use environment-specific settings for database, cache, and queue drivers
