Hi

I found a video on how this was done for bar-codes Prateeksha Singh - Frappe Controls, Barcode Controller - YouTube

Looking at this bar-codes, qr-codes can be done in the same way.

the controller

import Jsqrcode from ā€œqrcodejsā€;

frappe.ui.form.Controlqrcode = frappe.ui.form.ControlData.extend({
make_wrapper() {
// Create the elements for qrcode area
this._super();

	let $input_wrapper = this.$wrapper.find('.control-input-wrapper');
	this.qrcode_area = $(`<div class="qrcode-wrapper border"><svg height=80></svg></div>`);
	this.qrcode_area.appendTo($input_wrapper);
},

parse(value) {
	// Parse raw value
	return value ? this.get_qrcode_html(value) : "";
},

set_formatted_input(value) {
	// Set values to display
	const svg = value;
	const qrcode_value = $(svg).attr('data-qrcode-value');

	this.$input.val(qrcode_value);
	this.qrcode_area.html(svg);
},

get_qrcode_html(value) {
	// Get svg
	const svg = this.qrcode_area.find('svg')[0];
	Jsqrcode(svg, value, this.get_options(value));
	$(svg).attr('data-qrcode-value', value);
	return this.qrcode_area.html();
},

get_options(value) {
	// get Jsqrcode options
	let options = JSON.parse('{ "height" : 40 }');
	if (this.isValidJson(this.df.options)) {
		options = JSON.parse(this.df.options);
		if (options.format && options.format === "EAN") {
			options.format = value.length == 100 ? "EAN8" : "EAN13";
		}

		if (options.valueField) {
			// Set companion field value
			this.frm.set_value(options.valueField, value);
		}
	}
	return options;
},

isValidJson(jsonData) {
	try {
		JSON.parse(jsonData);
		return true;
	} catch (e) {
		return false;
	}
}

});

But this is the error i get when i use the bench build command

UNRESOLVED_IMPORT : ā€˜qrcodejsā€™ is imported by frappe/public/js/frappe/form/controls/qrcodegen.js, but could not be resolved Ć¢ā‚¬ā€œ treating it as an external dependency
Cannot find some dependencies. You may have to run ā€œbench setup requirementsā€ to install them.

any clues? thanks
