# Application Components

### I18N
If you want to store application messages in DB and to have ability to edit them from backend, run:
```
php console/yii message/migrate @common/config/messages/php.php @common/config/messages/db.php
```
it will copy all existing messages to database

Then uncomment config for `DbMessageSource` in
```php
common/config/base.php
```

### KeyStorage
Key storage is a key-value storage to store different information. Application settings for example.
Values can be stored both via api or by backend CRUD component.
```
Yii::$app->keyStorage->set('articles-per-page', 20);
Yii::$app->keyStorage->get('articles-per-page'); // 20
```

### Maintenance mode
Starter kit has built-in component to provide a maintenance functionality. All you have to do is to configure ``maintenance``
component in your config
```php
'bootstrap' => ['maintenance'],
...
'components' => [
    ...
    'maintenance' => [
        'class' => 'common\components\maintenance\Maintenance',
        'enabled' => Astronomy::isAFullMoonToday()
    ]
    ...
]
```
This component will catch all incoming requests, set proper response HTTP headers (503, "Retry After") and show a maintenance message.
Additional configuration options can be found in a corresponding class.

Starter kit configured to turn on maintenance mode if ``frontend.maintenance`` key in KeyStorage is set to ``true``

### Command Bus
- [What is command bus?](http://shawnmc.cool/command-bus)

In Starter Kit Command Bus pattern is implemented with [tactician](https://github.com/thephpleague/tactician) package and 
it's yii2 connector - [yii2-tactician](https://github.com/trntv/yii2-tactician)

Command are stored in ``common/commands/command`` directory, handlers in ``common/commands/handler``

To execute command run
```php
$sendEmailCommand = new SendEmailCommand(['to' => 'user@example.org', 'body' => 'Hello User!']);
Yii::$app->commandBus->handle($sendEmailCommand);
```

### Timeline (Activity)
```php
$addToTimelineCommand = new AddToTimelineCommand([
    'category' => 'user', 
    'event' => 'signup', 
    'data' => ['foo' => 'bar']
]);
Yii::$app->commandBus->handle($addToTimelineCommand);
```

### Behaviors
#### CacheInvalidateBehavior
```php
 public function behaviors()
 {
     return [
         [
             'class' => `common\behaviors\CacheInvalidateBehavior`,
             'tags' => [
                  'awesomeTag',
                   function($model){
                       return "tag-{$model->id}"
                  }
              ],
             'keys' => [
                  'awesomeKey',
                  function($model){
                      return "key-{$model->id}"
                  }
              ]
         ],
     ];
 }
```
#### GlobalAccessBehavior
Add in your application config:
```php
'as globalAccess'=>[
        'class'=>'\common\behaviors\GlobalAccessBehavior',
        'rules'=>[
            [
                'controllers'=>['sign-in'],
                'allow' => true,
                'roles' => ['?'],
                'actions'=>['login']
            ],
            [
                'controllers'=>['sign-in'],
                'allow' => true,
                'roles' => ['@'],
                'actions'=>['logout']
            ],
            [
                'controllers'=>['site'],
                'allow' => true,
                'roles' => ['?', '@'],
                'actions'=>['error']
            ],
            [
				'allow' => true,
				'roles' => ['@']
			]
        ]
    ]
```
It will allow access to you application only for authentificated users.

Good luck!
