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

• Use dependency injection

• Prefer composition over inheritance

• Keep controllers thin

• Use DTOs for API input/output

• Repository pattern for queries

• Voters for authorization

• Cache expensive operations

• TDD for critical features

Deployment Checklist

• APP_ENV=prod , APP_DEBUG=0

• composer install --no-dev --optimize-autoloader

• php bin/console cache:clear --env=prod

• npm run build

• php bin/console doctrine:migrations:migrate --env=prod
