This package provides abstract object factory allowing to create objects by given definition
with dependencies resolved by a [PSR-11](https://www.php-fig.org/psr/psr-11/) container.
## Requirements
- PHP 8.0 or higher.
## Installation
The package could be installed with [Composer](https://getcomposer.org):
```shell
composer require yiisoft/factory
```
## General usage
The factory is useful if you need to create objects using [definition syntax](https://github.com/yiisoft/definitions)
and/or want to configure defaults for objects created.
```php
$container = new PSR11DependencyInjectionContainer();
$factoryConfig = [
EngineInterface::class => [
'class' => EngineMarkOne::class,
'__construct()' => [
'power' => 42,
],
]
];
$factory = new Factory($container, $factoryConfig);
$one = $factory->create(EngineInterface::class);
$two = $factory->create([
'class' => EngineInterface::class,
'__construct()' => [
'power' => 146,
],
]);
```
In the code above we define factory config specifying that when we need `EngineInterface`, an instance of `EngineMarkOne`
will be created with `power` constructor argument equals to 42. We also specify that all the dependencies requested by
the object created should be resolved by `PSR11DependencyInjectionContainer`.
First call to `create()` uses default configuration of `EngineInterface` as is. Second call specifies custom
configuration for `power` constructor argument. In this case, configuration specified is merged with default
configuration overriding its keys when the key name is the same.
### Tuning for production
By default, the factory validates definitions right when they are set. In production environment, it makes sense to
turn it off by passing `false` as a third constructor argument:
```php
$factory = new Factory($container, $factoryConfig, false);
```
### Strict factory
`StrictFactory` differs in that it processes only configured definitions.
When attempting to request an existing class that is not defined in the factory config,
a `NotFoundException` will be thrown.
```php
$container = new PSR11DependencyInjectionContainer();
$factoryConfig = [
EngineInterface::class => [
'class' => EngineMarkOne::class,
'__construct()' => [
'power' => 42,
],
]
];
$factory = new Factory($factoryConfig, $container);
$engine = $factory->create(EngineInterface::class);
// Throws `NotFoundException`
$factory->create(EngineMarkOne::class);
```
