The new QR Code payment slips were introduced in Switzerland on June 30th, 2020 and should gradually replace the current payment slips.

Quick start

It's quite easy to create a simple QR bill. All you have to do is create a new SwissQRBill.PDF instance and pass your billing data object as the first parameter and your output path as the second parameter.

const SwissQRBill = require("swissqrbill");

const data = {
  currency: "CHF",
  amount: 1199.95,
  reference: "210000000003139471430009017",
  creditor: {
    name: "Robert Schneider AG",
    address: "Rue du Lac 1268",
    zip: 2501,
    city: "Biel",
    account: "CH4431999123000889012",
    country: "CH"
  },
  debtor: {
    name: "Pia-Maria Rutschmann-Schnyder",
    address: "Grosse Marktgasse 28",
    zip: 9400,
    city: "Rorschach",
    country: "CH"
  }
};

const pdf = new SwissQRBill.PDF(data, "qrbill.pdf", () => {
  console.log("PDF has been successfully created.");
});

This will create the above PDF file. You can pass an optional third parameter containing options such as language or size etc. as well as a callback function that gets called right after the file has finished writing. A complete documentation for all methods and parameters can be found in doc/api.md.

Browser usage

To use SwissQRBill inside browsers, you have to pass a writableStream in the second parameter, instead of the output path. To create a writableStream in the browser you can use the built in SwissQRBill.BlobStream() function.

const stream = new SwissQRBill.BlobStream();

const pdf = new SwissQRBill.PDF(data, stream);

pdf.on("finish", () => {
  const iframe = document.getElementById("iframe");
  if(iframe){
    iframe.src = stream.toBlobURL("application/pdf");
  }
  console.log("PDF has been successfully created.");
});

You can see a fully working example at https://github.com/schoero/SwissQRBill-browser-example.

Further informations

SwissQRBill extends PDFKit to generate PDF files and adds a few extra methods. You can generate a complete PDF bill using the original PDFKit methods and the additional methods documented in doc/api.md. The documentation for PDFKit can be found here.

A simple guide how to generate a complete bill can be found in doc/how-to-create-a-complete-bill.md. You will learn how to create a PDF that looks like this:
