@qrcode-js/node

Description

This is a wrapper around the core package, enabling creation of QRs on the server side, on Node environments.

Behind the scenes it uses the canvas package to use the canvas like the built-in in browsers.

Example

import QRCodeNode from "@qrcode-js/node";
import { promises as fs } from "fs";

async function main() {
  const myQR = QRCodeNode({
    text: "https://github.com/qrcode-js/qrcode",
    colorDark: "#123456",
    size: 1000,
    logo: { round: 0.4, margin: 0 },
    dots: {
      scale: 0.75,
      round: 1,
    },
    finder: {
      round: 0.5,
    },
    gradient: (ctx, size) => {
      const gradient = ctx.createLinearGradient(0, 0, size, 0);
      gradient.addColorStop(0, "green");
      gradient.addColorStop(0.5, "grey");
      gradient.addColorStop(1, "red");
      return gradient;
    },
    drawFunction: "telegram",
    // drawFunction: (
    //   canvasContext,
    //   left,
    //   top,
    //   nSize,
    //   scale,
    //   round,
    //   parameters,
    //   otherCells
    // ) => {
    //   if (parameters.isTiming) {
    //     AwesomeQR._drawDot(canvasContext, left, top, nSize, scale, round);
    //   }
    // },
  });

  await fs.mkdir("dist", { recursive: true });
  await myQR.draw().then((d) => fs.writeFile("dist/qrcode.png", d));
}
main().catch(console.error);
