QR Layout Tool is a complete solution for building applications that generate dynamic, printable QR code labels, stickers, and badges. Unlike basic QR generators that produce a single image, this tool gives you a full layout engine with a visual designer, data binding, and multi-format export.

It is split into two focused npm packages:

Package	Purpose
`qrlayout-core`	Headless rendering engine — use in any JS/TS project
`qrlayout-ui`	Embeddable drag-and-drop visual designer

Quick Start

Headless (Core only)

npm install qrlayout-core

import { StickerPrinter } from "qrlayout-core";

const printer = new StickerPrinter();

const layout = {
  id: "badge",
  name: "Employee Badge",
  width: 100, height: 60, unit: "mm",
  elements: [
    { id: "name", type: "text", x: 5, y: 5, w: 90, h: 12, content: "{{name}}", style: { fontSize: 16, fontWeight: "bold" } },
    { id: "qr",   type: "qr",   x: 35, y: 20, w: 30, h: 30, content: "{{id}}" }
  ]
};

const zplPages = printer.exportToZPL(layout, [
  { name: "Alice",   id: "EMP-001" },
  { name: "Bob",     id: "EMP-002" },
  { name: "Charlie", id: "EMP-003" },
]);

Embedded Visual Designer

npm install qrlayout-ui qrlayout-core

import { QRLayoutDesigner } from "qrlayout-ui";
import "qrlayout-ui/style.css";

const designer = new QRLayoutDesigner({
  element: document.getElementById("editor"),
  onSave: (layout) => {
    fetch("/api/layouts", { method: "POST", body: JSON.stringify(layout) });
  }
});

PDF Export (optional)

npm install jspdf

import { exportToPDF } from "qrlayout-core/pdf";

const pdf = await exportToPDF(layout, [data1, data2]);
pdf.save("badges.pdf");

How It Works

The layout JSON from qrlayout-ui is your single source of truth — store it in your database, load it back anytime, and pass it with real records to qrlayout-core to generate labels.

// Save from the designer
onSave: async (layout) => {
  await fetch("/api/layouts", { method: "POST", body: JSON.stringify(layout) });
}

// Later — fetch and print
const layout  = await fetch("/api/layouts/employee-badge").then(r => r.json());
const records = await fetch("/api/employees").then(r => r.json());

const printer = new StickerPrinter();
const pdf = await printer.exportToPDF(layout, records);
pdf.save("badges.pdf");
