Introducing small/dependency-injection

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
Enter fullscreen mode Exit fullscreen mode

Define your container configuration:

<?php 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; } }
Enter fullscreen mode Exit fullscreen mode

Use it:

$config = new AppConfig(__DIR__ . '/composer.json'); $config->loadParameters($container); $myService = $container->get(MyServiceInterface::class);
Enter fullscreen mode Exit fullscreen mode

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