## Specification pattern for Laravel
Implementation of the Specification pattern in PHP
## Requirements
* PHP 8.1+
## Installation
You can install the package via composer:
``` bash
$ composer require kaivladimirv/laravel-specification-pattern
```
## Usage
You can create a specification using the artisan command:
``` bash
$ php artisan make:specification GreaterThanSpecification
```
This command will create a specification class in the App\Specifications namespace.
``` php
number";
}
protected function executeCheckIsSatisfiedBy(mixed $candidate): bool
{
- return false;
+ return $candidate > $this->number;
}
}
```
After adding business logic, you can use the specification by calling the isSatisfiedBy or throwExceptionIfIsNotSatisfiedBy methods.
### Using the isSatisfiedBy method:
``` php
$greaterThan100Spec = new GreaterThanSpecification(100);
$greaterThan100Spec->isSatisfiedBy(200); // true
$greaterThan100Spec->isSatisfiedBy(99); // false
```
### Using the throwExceptionIfIsNotSatisfiedBy method:
``` php
$greaterThan100Spec = new GreaterThanSpecification(100);
$greaterThan100Spec->throwExceptionIfIsNotSatisfiedBy(200); // No exception will be thrown here
$greaterThan100Spec->isSatisfiedBy(99); // An DomainException will be thrown here with the message "Number must be greater than 100"
```
You can change the exception type in the getExceptionClass method:
``` diff
number";
}
protected function executeCheckIsSatisfiedBy(mixed $candidate): bool
{
return $candidate > $this->number;
}
+
+ protected function getExceptionClass(): string
+ {
+ return MyException::class;
+ }
}
```
