Laravel Value Objects is a fantastic package that offers a bunch of general-purpose value objects you can use in your Laravel application.
The package requires PHP ^8.0 and Laravel ^9.7.
Installation
Install the package using composer:
composer require michael-rubel/laravel-value-objects
Artisan command
You can generate custom value objects with the Artisan command:
php artisan make:value-object YourNameValueObject
Usage
Boolean
$bool = new Boolean('1');
$bool = Boolean::make('1');
$bool = Boolean::from('1');
$bool->value(); // true
(string) $bool; // 'true'
$bool->toArray(); // ['true']
Decimal
$decimal = new Decimal('10.20999', scale: 2);
$decimal = Decimal::make('10.20999', scale: 2);
$decimal = Decimal::from('10.20999', scale: 2);
$decimal->value(); // '10.20'
(string) $decimal; // '10.20'
$decimal->toArray(); // ['10.20']
Integer
$integer = new Integer(10);
$integer = Integer::make(10);
$integer = Integer::from(10);
$integer->value(); // 10
(string) $integer; // '10'
$integer->toArray(); // [10]
Text
$text = new Text('Lorem Ipsum is simply dummy text.');
$text = Text::make('Lorem Ipsum is simply dummy text.');
$text = Text::from('Lorem Ipsum is simply dummy text.');
$text->value(); // 'Lorem Ipsum is simply dummy text.'
(string) $text; // 'Lorem Ipsum is simply dummy text.'
$text->toArray(); // ['Lorem Ipsum is simply dummy text.']
ClassString
$classString = new ClassString('\Exception');
$classString = ClassString::make('\Exception');
$classString = ClassString::from('\Exception');
$classString->value(); // '\Exception'
(string) $classString; // '\Exception'
$name->toArray(); // ['\Exception']
$classString->classExists(); // true
$classString->interfaceExists(); // false
$classString->instantiate(); // Exception { ... }
$classString->instantiateWith(['message' => 'My message.']); // Exception { #message: "test" ... }
Name
$name = new Name(' Company name! ');
$name = Name::make(' Company name! ');
$name = Name::from(' Company name! ');
$name->value(); // 'Company name!'
(string) $name; // 'Company name!'
$name->toArray(); // ['Company name!']
Handle failed validation
If you want to avoid try/catching your value object when the validation fails, you can use makeOrNull method:
$bool = Boolean::makeOrNull('bad input'); // null
$bool?->value(); // null
Extending functionality
All value objects are Macroable. This way you can add new methods dynamically. If you need to extend existing methods, you can create a value object locally with make:value-object command and use inheritance.
For example:
ValueObject::macro('str', function () {
return str($this->value());
});
$name = new Text('Lorem ipsum');
$name->str()->is('Lorem ipsum'); // true
Conditionable
Value objects utilize a Conditionable trait. You can use when and unless methods.
TaxNumber::from('PL0123456789')->when(function ($number) {
return $number->prefix() !== null;
})->prefix();
