How to use piu/MC/QRCode?

[wilberforce]

I've tried:
mainfest...

{ "modules": {
...
		"piu/MC/QRCode":"$(PIU)/MC/qrcode/piuQRCode"
}

main.js:

import {QRCode} from "piu/MC/QRCode";
const QR=new QRCode(null,{top: 20, bottom: 20, left: 20, right: 20, 	style: textStyle, string: "Ready to install apps!"})


class AppBehavior extends Behavior {
	onCreate(app) {
	      app.add(QR);
}
....

p.s. using unicode block █ and spaces x 2 yields this trace output which then can be scanned by phone:

code = new Uint8Array(code);
for (let y = 0; y < size; y++) {
  for (let x = 0; x < size; x++) {
      if (code[(y * size) + x])
          trace("██");
      else
          trace("  ");
  }
  trace("\n");
}

Here's what we usually do. Include the QR Code bits in the manifest:

	"modules": {
		"piu/QRCode": "$(MODULES)/piu/MC/qrcode/piuQRCode",
		"*": [
			"$(MODULES)/data/qrcode/qrcode",
			"$(MODULES)/data/qrcode/qrcodegen"
		]
	},
	"preload": [
		"qrcode",
		"qrcodegen",
		"piu/QRCode"
	]

Then instantiate the Piu QR code object (code here from a template):

QRCode($, { width:110, top:30, height:110, skin: {fill:WHITE, stroke:BLACK}, string: "The message", maxVersion:10 })

Thanks.

Sorry, I don't follow the template part or understand where $ fits in

[phoddie]

manifest.json (adds Commodetto QR code rendering support missing above, apologies):

{
	"include": [
		"$(MODDABLE)/examples/manifest_base.json",
		"$(MODDABLE)/examples/manifest_piu.json",
		"$(MODDABLE)/modules/commodetto/qrcode/manifest.json",
		"$(MODDABLE)/modules/data/qrcode/manifest.json"
	],
	"modules": {
		"*": [
			"./main",
		],
		"piu/QRCode": "$(MODULES)/piu/MC/qrcode/piuQRCode"
	},
	"preload": [
		"piu/QRCode"
	]
}

main.js:

import {} from "piu/MC";

new Application(null, {
	skin: new Skin({
		fill: "silver"
	})
});

application.add(new QRCode(null, {
	width: 160, height: 160,
	skin: {
		fill: "white",
		stroke: "black"
	},
	string: "This is a message.",
	maxVersion: 10
}));

Result:

Thanks.

"$(MODDABLE)/modules/commodetto/qrcode/manifest.json", was the missing secret sauce!
