SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps developers implement robust, production-grade Symfony applications by leveraging advanced Dependency Injection (DI) patterns, ensuring maintainable and scalable code.

Core Features & Use Cases

Interface Binding: Seamlessly bind interfaces to their concrete implementations for flexible architecture.
Autowiring: Utilize Symfony's powerful autowiring for automatic dependency injection.
Service Decoration: Extend existing services without modifying their original code.
Tagged Services: Group and inject multiple services implementing a common interface.
Use Case: Refactor a legacy service to use interface binding and autowiring, making it easier to test and swap implementations later.

Quick Start

Use the symfony:interfaces-and-autowiring skill to bind the PaymentGatewayInterface to the StripePaymentGateway implementation in config/services.yaml.

FAQPage Schema

How do I bind an interface to a concrete implementation in Symfony?▼

Interface binding in Symfony maps an abstraction to a concrete class by configuring the service container, allowing autowiring to resolve the correct implementation automatically when the interface is type-hinted.

What is the best way to extend a Symfony service without modifying its original code?▼

Service decoration is the best way to extend a Symfony service, allowing you to wrap an existing service with new logic while preserving the original implementation and maintaining core application stability.

How does autowiring work with tagged services in Symfony?▼

Autowiring with tagged services automatically collects and injects all services sharing a common tag, typically grouping multiple implementations of a single interface into an iterator for streamlined dependency management.

When do I need interface binding for dependency injection in Symfony?▼

You need interface binding when decoupling your architecture, allowing you to swap implementations easily for testing or production changes without modifying the consuming services that rely on the interface abstraction.

Can I use readonly properties with constructor injection in Symfony services?▼

Yes, you can use readonly properties with constructor injection in Symfony services to enforce immutability, ensuring that dependencies remain unchanged after instantiation for robust service management.

Why does Symfony recommend minimal interfaces for service management?▼

Symfony recommends minimal interfaces to prevent tight coupling, ensuring that service contracts remain narrow and focused, which simplifies dependency injection and makes architectural refactoring safer.
