Why do I need it

For intercept calls to classes and abstract part of the logic to smaller classes

Installation

Install with composer

composer require larapackages/interceptor

Publish

php artisan vendor:publish --provider="Larapackages\Interceptor\Providers\InterceptorServiceProvider"

Usages

In your SomeClass implements Larapackages\Interceptor\InterceptorInterface.

class SomeClass implements \Larapackages\Interceptor\InterceptorInterface {
    public static function interceptors(): array
    {
        return [
            // Classes namespaces that will intercept this class
        ];
    }
};

The you must use Laravel container to make the class for interceptor works.

Laravel container resolving documentation

$class = app()->make(SomeClass::class);
$class = resolve(SomeClass::class);

Modifying arguments

class ArgInterceptor {
    public function getName($name) {
        $name = mb_strtoupper($name);
        
        return compact('name');
    }
};

class ArgClass implements \Larapackages\Interceptor\InterceptorInterface {
    public function getName($name) {
        return $name;
    }

    public static function interceptors(): array
    {
        return [
            ArgInterceptor::class
        ];
    }
};

$class = app()->make(ArgClass::class)->getName('fake'); //Will return Fake

Validate data

class ArgInterceptor {
    public function getValidData(array $data) {
        $validator = \Illuminate\Support\Facades\Validator::make($data, [
            'id' => 'required',
        ])->validate();
    }
};

class ArgClass implements \Larapackages\Interceptor\InterceptorInterface {
    public function getValidData(array $data) {
        return $data;
    }

    public static function interceptors(): array
    {
        return [
            ArgInterceptor::class
        ];
    }
};

$class = app()->make(ArgClass::class)->getValidData(['name' => 'fake']); //Will throw a validation exception
$class = app()->make(ArgClass::class)->getValidData(['id' => 1]); //Will return ['id' => 1]

Return responses

class ArgInterceptor {
    public function getName(string $name) {
        if ($name === 'test') {
            return 'Test Name';
        }
    }
};

class ArgClass implements \Larapackages\Interceptor\InterceptorInterface {
    public function getName(string $name) {
        return $name;
    }

    public static function interceptors(): array
    {
        return [
            ArgInterceptor::class
        ];
    }
};

$class = app()->make(ArgClass::class)->getName('test'); //Will return Test Name
$class = app()->make(ArgClass::class)->getName('second test'); //Will return second test

Cache

In order to improve performance, this package have two commands to generate and clear cache. Package will automatically use the cache file if exists, otherwise it scans the paths.

Generate cache:

php artisan interceptor:cache

Clear cache:

php artisan interceptor:clear
