Auryn is awesome, so why not use it as a container when packages require it?
Note: This goes completely against the philosophy of not using Auryn as a service locator. This package is only meant to be a pragmatic solution for Auryn users that want to use a package that requires a service locator.
Attempts to be PSR-1, PSR-2, PSR-4, and PSR-11 compliant.
composer require northwoods/container
use Auryn\Injector;
use Northwoods\Container\InjectorContainer;
use Psr\Container\ContainerInterface;
// Make an Injector and configure it.
$injector = new Injector();
// Optional: Declare a single container instance.
$injector->share(ContainerInterface::class);
// Use InjectorContainer as the implementation of ContainerInterface.
$injector->alias(ContainerInterface::class, InjectorContainer::class);
// InjectorContainer will wrap this Injector instance.
$injector->define(InjectorContainer::class, [':injector' => $injector]);
This package provides a InjectorBuilder
that can be used to configure Auryn using separate classes.
The builder takes a list of configuration objects and applies each of them to the injector.
use Northwoods\Container\Config\ContainerConfig;
use Northwoods\Container\InjectorBuilder;
$builder = new InjectorBuilder([
new ContainerConfig(),
]);
If you prefer to have the injector instantiate the configuration classes, use the LazyInjectorBuilder
:
use Northwoods\Container\Config\ContainerConfig;
use Northwoods\Container\LazyInjectorBuilder;
$builder = new LazyInjectorBuilder([
ContainerConfig::class,
]);
The builder can then be used to create an Injector
instance:
$injector = $builder->build();
$container = $injector->make(ContainerInterface::class);
Note: An existing instance of Auryn can also be provided to the build()
method.
This package is compatible with Zend Expressive Container Config:
use Northwoods\Container\Zend\Config;
use Northwoods\Container\Zend\ContainerFactory;
$factory = new ContainerFactory();
$container = $factory(new Config(
require 'path/to/services.php',
));
Note: All injections configured this way will be shared!
An existing Injector
can also be passed into ContainerFactory
:
$factory = new ContainerFactory($injector);
This can be combined with InjectorBuilder
or LazyInjectorBuilder
to apply
configuration such as define()
calls.
PSR-11 does not require the container identifier to be a class name, while Auryn does. The only exception to this rule in Auryn is that a class alias can be anything. These container "service names" must resolve to a class and will need to be aliased.
For example a package may require a config
entry in the container that is meant to resolve to an array.
This can be achieved by creating a delegate that creates an instance of ArrayObject
:
use ArrayObject;
use Auryn\Injector;
use Northwoods\Container\InjectorContainer;
// Share a global "config" array as an object
$injector->share('config')->delegate('config', function () {
return new ArrayObject(require 'path/to/config.php');
});
// Create the container
$container = new InjectorContainer($injector);
Now whenever $container->get('config')
is called the ArrayObject
will be returned.

directory.
