Real Time Web with Node.js | 6.7 Answering Questions

readMe.txt

Clients can also answer each other's questions, 
so let's build that feature by first listening for
the 'answer' event on the client, which will send us
both the question and answer, which we want to broadcast 
out to the rest of the connected clients.

save-data.js

var express = require('express');
var app = express();
var server = require('http').createServer(app);
var io = require('socket.io')(server);

io.sockets.on('connection', function(client) {
  console.log("Client connected...");

  client.on('answer', function(question, answer) {
    client.broadcast.emit('answer', question, answer);
  });
  

  client.on('question', function(question) {
    if(!client.question_asked) {
      client.question_asked = true;
      client.broadcast.emit('question', question);
    }
  });
});

server.listen(8080);
