First.
You don't need to find a way to implement ValueObjects.
You should only make a "app/ValueObjects" directory.
But, I released the package "imunew/laravel-value-objects" that you can generate files automatically by the "php artisan make:value-object" command.
The source code is here.
You can install it with "composer require imunew/laravel-value-objects".
I want a ValueObject like this
The following is what we are looking for in a ValueObject.
- immutable
- Only set data only with the __construct
- Don't make the setter public
-
@property-readableproperties can be accessed
- Like the
EloquentModel- No need to write getter per properties
- Can implement Accessor (get{Attribute}Attribute)
- You can create a file with the command "php artisan make:value-object".
I tried to find a package on packagist, but there was none that met my requirements.
The chalcedonyt/laravel-valueobject is immutable, and has a make command, which is nice, but, unfortunately, it stopped being updated after 2015-11-13 and was not compatible with Laravel 6.x or later.
It works like this.
Example 1) Range class.
namespace App\ValueObjects;
use Imunew\Laravel\ValueObjects\ImmutableObject;
class Range extends ImmutableObject
{
/**
* Range constructor.
* @param int $start
* @param int $end
* @param int $step
*/
public function __construct(int $start, int $end, int $step = 1)
{
$this->setAttribute('start', $start);
$this->setAttribute('end', $end);
$this->setAttribute('step', $step);
}
/**
* @return array
*/
public function getRangeAttribute()
{
return range($this->start, $this->end, $this->step);
}
}
$range = new Range(1, 10);
echo $range;
// [1,2,3,4,5,6,7,8,9,10]
Example 2) DirectoryTree class
namespace App\ValueObjects;
use Imunew\Laravel\ValueObjects\ImmutableObject;
class DirectoryTree extends ImmutableObject
{
/**
* Range constructor.
* @param array $directoryTree
*/
public function __construct(array $directoryTree)
{
$this->attributes = $directoryTree;
}
}
$directoryTree = new DirectoryTree([
'app' => [
'Http' => [
'Controllers' => [],
'Middleware' => [],
'Requests' => [],
'Resources' => [],
],
'ValueObjects' => []
]
]);
echo json_encode($directoryTree->get('app.Http'));
// {"Controllers":[],"Middleware":[],"Requests":[],"Resources":[]}
Conclusion.
I think I've created a nice Laravel package.
Please try to use it.
Bye.
