import { DeviceEventEmitter } from 'react-native';

let HANDSHAKE_MESSAGE = "My cool message"


DeviceEventEmitter.addListener('handshakeServerStarted', function(e){
  console.log("handshakeServerStarted");
  console.log(e.port);
});

DeviceEventEmitter.addListener('handshakeServerStopped', function(e){
  console.log("handshakeServerStopped");
});

DeviceEventEmitter.addListener('peerPubKeyReceived', function(e){
  console.log("JS: peer public key received");
  console.log(e.key);
});

// Start the server. Will emit HANDSHAKE_MESSAGE to any client that connects 
Handshake.startServer(HANDSHAKE_MESSAGE);

// receive a Handshake message from a server/peer. Will emit a peerPubKeyReceived event with the handshake message received (key).
Handshake.receiveKey(e.host, e.port);

// Stop the handshake server
Handshake.stopServer()
