README

Switon's dependency injection container for autowiring, named services, and bootstrap wiring.

Highlights

• Shared container: ContainerInterface handles service resolution and definition registration.
• Service autowiring: #[Autowired] can inject object services without manual lookups.
• Config autowiring: the same attribute can fill scalar and array properties from config.
• Named instances: FactoryInterface supports multiple implementations of the same type.
• Lazy dependencies: Lazy defers non-default resolution until a value is actually used.
• Autowired instances: #[Autowired(instances: true)] can inject service arrays from config.

Installation

composer require switon/di
