Symfony Framework Development Skill

Instructions à Exécuter

IMPORTANT : Exécute ce workflow étape par étape :

Quick Start

# Full web app
symfony new project_name --version="6.4.*" --webapp

# API/Microservice
symfony new project_name --version="6.4.*"

# Without CLI
composer create-project symfony/skeleton:"6.4.*" project_name

Core Patterns

Controller

• Extend AbstractController
• Use attributes for routing: #[Route('/path', name: 'route_name')]
• Automatic entity parameter conversion

Services

• Autowiring by default
• Configure in config/services.yaml

Doctrine

• Create entity: php bin/console make:entity
• Create migration: php bin/console make:migration
• Execute: php bin/console doctrine:migrations:migrate

Forms

• Dedicated FormType classes
• Handle in controller: createForm(), handleRequest(), isSubmitted(), isValid()

Security

• Configure in config/packages/security.yaml
• Use Voters for authorization

Essential Commands

php bin/console cache:clear
php bin/console debug:router
php bin/console debug:container
php bin/console make:controller
php bin/console make:crud Product

Best Practices

1. Use dependency injection
2. Prefer composition over inheritance
3. Keep controllers thin
4. Use DTOs for API input/output
5. Repository pattern for queries
6. Voters for authorization
7. Cache expensive operations
8. TDD for critical features

Deployment Checklist

1. APP_ENV=prod, APP_DEBUG=0
2. composer install --no-dev --optimize-autoloader
3. php bin/console cache:clear --env=prod
4. npm run build
5. php bin/console doctrine:migrations:migrate --env=prod
