I’ve just released small/dependency-injection — a lightweight, framework-agnostic Dependency Injection container for PHP 8.4.
Quick Start
Install via Composer:
composer require small/dependency-injection
Define your container configuration:
use Small\DependencyInjection\AbstractContainerConfiguration;
use function Small\DependencyInjection\injectService;
use function Small\DependencyInjection\injectParameter;
class AppConfig extends AbstractContainerConfiguration
{
public function configure(): self
{
$this->parameter('secret', 'top-secret')
->service(
MyServiceInterface::class,
MyService::class,
[
injectParameter('secret'),
injectService(LoggerInterface::class),
]
)
->autowireNamespace('App');
return $this;
}
}
Use it:
$config = new AppConfig(__DIR__ . '/composer.json');
$config->loadParameters($container);
$myService = $container->get(MyServiceInterface::class);

That’s it — a simple, modern DI container for your next PHP project.
