10 months ago I've converted the index.ts under src into the js code below and imported the jsQR lib (https://github.com/cozmo/jsQR/tree/master/dist) and then I was able to set up the QR reader in quaqa and read qr codes.
Maybe you should publish the JS component too. Not everyon is using TS in their projects.
var QrCodeReader = /** @class */ (function () {
function QrCodeReader(config, supplements) {
this._row = [];
this.config = config || {};
this.supplements = supplements;
this.FORMAT = {
value: 'qr_code',
writeable: false,
};
return this;
}
QrCodeReader.prototype.decodeImage = function (inputImageWrapper) {
var data = inputImageWrapper.getAsRGBA();
var result = jsQR(data, inputImageWrapper.size.x, inputImageWrapper.size.y);
if (result === null) {
return null;
}
// TODO: translate result.location into same values as box/boxes from other readers?
return {
codeResult: {
code: result.data,
format: this.FORMAT.value,
},
...result,
};
}
// eslint-disable-next-line class-methods-use-this,@typescript-eslint/no-unused-vars
QrCodeReader.prototype.decodePattern = function (pattern) {
// STUB, this is probably meaningless to QR, but needs to be implemented for Quagga, in case
// it thinks there's a potential barcode in the image
return null;
};
return QrCodeReader;
}());In my js app code , i've added:
Quagga.registerReader('qrcode', QrCodeReader);
and in the readers list added: "qrcode"

Hi,
Where from can I download a pure JS version of this module?
I'm not seeing any dist folder in this repo, not I was able to locate any pege on the internet where from I can download the QR code module for quagga2.
@ericblade/quagga2-reader-qr on npmjs is not available either.
I need a version that will work in a pure javascript app. No react, jquery and/or any other lib dependency of this kind and no TS either.
Thanks
