QrCodeComponent

This Yii2 Application Component can truly ease the task to create QrCodes to Yii developers. It wraps all the methods and functionality of Da\QrCode\QrCode class and developers do not need to deal with initialization process every time they use it.

Usage

// in components config of Yii2 app

'components' => [
// ... 
    'qr' => [
        'class' => '\Da\QrCode\Component\QrCodeComponent',
        // ... you can configure more properties of the component here
    ]
// ...
]

Once configured, you can access the component like this:

// on your controller's action

$qr = Yii::$app->get('qr');

Yii::$app->response->format = Response::FORMAT_RAW;
Yii::$app->response->headers->add('Content-Type', $qr->getContentType());

return $qr
    ->setText('https://2amigos.us')
    ->setLabel('2amigos consulting group llc')
    ->writeString();
