export default function App() {
  // State variables
  const [peers, setPeers] = React.useState([]);
  const [message, setMessage] = React.useState('');
  const [progress, setProgress] = React.useState('');
  const [received, setReceived] = React.useState('');

  // Subscribe to discover peers event
  React.useEffect(() => {
    const discoverPeerSubscription = subscribeDiscoverPeer((peers) => {
      setPeers(JSON.parse(peers));
    });
    discoverPeers('ip');

    return () => {
      discoverPeerSubscription.remove();
    };
