Containers

Using Aura.Di

Aura.Di provides a serializable dependency injection container with the following features:

• constructor and setter injection.
• inheritance of constructor parameter and setter method values from parent classes.
• inheritance of setter method values from interfaces and traits.
• lazy-loaded instances, services, includes/requires, and values.
• instance factories.
• optional auto-resolution of typehinted constructor parameter values.

Installing Aura.Di

Aura.Di implements PSR-11 as of version 3. To use Aura.Di as a dependency injection container, we recommend using laminas/laminas-auradi-config, which helps you to configure its container. First, install the package:

$ composer require laminas/laminas-auradi-config

Configuration

To configure Aura.Di, create the file config/container.php with the following contents:

<?php

use Laminas\AuraDi\Config\Config;
use Laminas\AuraDi\Config\ContainerFactory;

$config = require __DIR__ . '/config.php';
$factory = new ContainerFactory();
return $factory(new Config($config));

Your bootstrap (typically public/index.php) will then look like this:

chdir(dirname(__DIR__));
require 'vendor/autoload.php';
$container = require 'config/container.php';
$app = $container->get(Mezzio\Application::class);
require 'config/pipeline.php';
require 'config/routes.php';
$app->run();
