A websocket server sending screenshot as base64 encoded blob

screenshot-websocket.js

// Requires ws and screenshot-desktop

const WebSocket = require('ws');
const screenshot = require('screenshot-desktop')

const wss = new WebSocket.Server({ port: 8889 });

wss.on('connection', function connection(ws) {
  ws.on('message', function incoming(message) {
    console.log('received: %s', message);
  });

  ws.on('close', ()=>{
    clearInterval(interval);
    console.log("disconnect")
  })
  console.log("connect")

  const interval = setInterval(()=>{
    screenshot({
        format: 'jpg'
    }).then(img => {
      ws.send(img);
    })
  }, 500)
});

Hi, I'm a security researcher participating in Google VRP. I have a few security related questions about this gist.

1. Is there a channel for reporting vulnerabilities of this gist?
2. Is this gist related to Teachable Machine?
3. Are users expected to run this code on their computers, or is it not meant to be run as-is?

Thank you.
