Laravel Presenter

A package that helps to group methods that mostly use for the view presentation purpose.

Installation

Require the package using composer:

composer require touhidurabir/laravel-presenter

To publish the config file:

php artisan vendor:publish --provider="Touhidurabir\Presenter\PresenterServiceProvider" --tag=config

Configurations

Check the published config file for the details of configurations options.

Usage

First step is to generate a presenter class . To make this process easy, this package comes with a command that helps to generate the presenter classes. To generate the presenter class via command, do as

php artisan make:presenter PresenterClassName

For example :

php artisan make:presenter UserPresenter

will generate a UserPresenter at the App\Presenters namespaced path.

it will have following content

namespace Touhidurabir\Presenter\Tests\App\Presenters;

use Touhidurabir\Presenter\BasePresenter;

class UserPresenter extends BasePresenter {

}

Now to use this with the combination of User model class, drop the HasPresenter trait and defined property $presenter as :

use Illuminate\Database\Eloquent\Model;
use Touhidurabir\Presenter\HasPresenter;
use Touhidurabir\Presenter\Tests\App\Presenters\UserPresenter;

class User extends Model {

    use HasPresenter;

    protected $presenter = UserPresenter::class;
}

Now to define a method in our presenter class, follow as :

class UserPresenter extends BasePresenter {

    public function someMethod() {

        return $this->model->some_presentable_data;
    }
}

And Now any public method defined in the UserPresenter class can be accesses as :

$user->present()->someMethod

It is also possible to not define the $presenter property while using the presenter class for models . In that case it will try to resolve the presenter through the model name and default store namespace defined in the config file .

For example, by default it will try to find a class in the App\Presenters location with name of UserPresenter for User model if the $presenter property not set in the User model. If it can find it, then it will use that for User model presenter . If none found, it will throw exception.

It is also possible to set/update the presenter on fly . To do that , need to user the setPresenter method defined in the HasPresenter trait as :

$user->setPresenter(UserPresenter::class);
$user->present()->anyMethodDefinedInPresenter;
