Generate a QR Code from a string (directive only)

Now that Angular/Ionic knows about the new QR Code module, let's invoke it from our template with a directive. If we use a simple text-string, we need no additional code in our controller.

<qrcode [qrdata]="'Your data string'" [width]="256" [errorCorrectionLevel]="'M'"></qrcode>

Create a QR Code from a variable in your controller

In addition to our <qrcode>-directive in example.html, lets add two lines of code to our controller example.ts.

// File: example.ts
export class QRCodeComponent {
  public myAngularxQrCode: string = null;
  constructor () {
    // assign a value
    this.myAngularxQrCode = 'Your QR code data string';
  }
}

// File: example.html
<qrcode [qrdata]="myAngularxQrCode" [width]="256" [errorCorrectionLevel]="'M'"></qrcode>

Parameters

Note

Depending on the amount of data of the qrdata to encode, a minimum width is required.
