yii2-facades

Facades support for Yii 2 application components & classes like Laravel

🟡 Installation

Step 1

Run composer require abahrami13/yii2-facades command.

Step 2

Add abahrami13\facades\RegisterFacadeAutoloader to the bootstrap array in the configuration file (config/web.php in the basic template).

🟡 Usage

🔷 Components facades namespaces

1) Yii2 Components

To use component facade, just import a class started with facades\ followed by the component id. For example for using facade of request component just import facades\Request:

use facades\Request;

2) Other Classes

To use facade for other classes, just add facades\ to the start of the class namespace.

For example, for using facade for the app\models\LoginForm class, just import facades\app\models\LoginForm class

🔷 Utilizing Facades

Just call the desired method statically & enjoy :)

For components:

Request::get('foo') is equal to Yii::$app->request->get('foo')

For other classes

LoginForm::rules()

is equal to

$loginForm = new LoginForm();

$loginForm->rules()
