In order to deal with the QR Code image file convenience, we start supporting the following two new methods in the FileBox v0.10:

FileBox.fromQRCode(qrCodeValue: string)

Get a FileBox instance that represent a QR Code value.

const fileBox = FileBox.fromQRCode('https://github.com')
fileBox.toFile('qrcode.png')

fileBox.toQRCode(): Promise<string>

Decode the QR Code value from the file.

const fileBox = FileBox.fromFile('qrcode.jpg')
const qrCodeValue = await fileBox.toQRCode()
console.log(`QR Code decoded value is: "${qrCodeValue}"`)
// Output: QR Code decoded value is: "https://github.com"

I hope you will enjoy it!
