websocket + facebook

[Marcelo Pignataro]

Hi community,

I'm using ws module on node.js and I'm trying to send a notification to a webrtc client when I receive a facebook chat from a facebook user, but I can't integrate ws code with node.js code for facebook API.

I have this node.js code using ws module: 

var WebSocketServer = require('ws');

var wss = new WebSocketServer.Server({port: 8080});

wss.on('connection', function(ws) {

      ws.on('message', function(message) {

          console.log('received: %s', message);

      });

      ws.send('something');

  });

And I have this node.js code for facebook api:

function sendTextMessage(recipientId, messageText) {

((HERE I NEED TO MAKE A ws.send('something'); ))

  var messageData = {

    recipient: {

      id: recipientId

    },

    message: {

      text: 'hi, I'm a bot',

      metadata: "DEVELOPER_DEFINED_METADATA"

    }

  };

  callSendAPI(messageData);

}

LAST CODE (facebook) is taken from a code published as example on facebook quick start tutorial such as "first steps with facebook messenger platform"(https://github.com/fbsamples/messenger-platform-samples/blob/master/node/app.js)
