QRCode 🤳

This lib was created with the goal of being as small and simple as possible, therefore, it only creates the BR Code. If you need to transform it into a QR Code, there are many ways to do it. I recomend using the qrcode lib. Here is an example:

First, install the qrcode lib:

#NPM
npm i qrcode

#YARN
yarn add qrcode

Then import it into your application:

import QRCode from "qrcode";

On your HTML, create an Canvas element with an id

<canvas id="canvas"></canvas>

Then use .toCanvas to create a QR Code from the BR Code

import { dinamicPix, staticPix } from "pix-charge";

let brCode = staticPix({
  merchantKey: "[e-mail]",
  merchantName: "Gabriel Molter",
});

QRCode.toCanvas(document.getElementById("canvas"), brCode, (error) => {
  if (error) {
    console.error(error);
  } else {
    console.log("success!");
  }
});
