Capturing QR Code

An event is emitted every time the QR code is received by the system. You can grab hold of this event emitter by importing ev. You can capture this qr code and save it to a file.

import { ev } from '@open-wa/wa-automate';
const fs = require('fs');

ev.on('qr.**', async qrcode => {
  //qrcode is base64 encoded qr code image
  //now you can do whatever you want with it
  const imageBuffer = Buffer.from(
    qrcode.replace('data:image/png;base64,', ''),
    'base64'
  );
  fs.writeFileSync('qr_code.png', imageBuffer);
});
