Read Connect sessions in engine.io


An engine.io plugin that allows you to read sessions created by the Connect session middleware.

It obtains the session id from the HTTP request headers and fetches the session data from a specified session store.

npm install engine.io-session
var http = require('http');
var connect = require('connect');
var eio = require('engine.io');
var eioSession = require('engine.io-session');
var app = connect();
var cookieParser = connect.cookieParser();
var sessionStore = new connect.session.MemoryStore();
var sessionKey = 'sid';
var sessionSecret = 'your secret here';
app.use(connect.session({ store: sessionStore, key: sessionKey, secret: sessionSecret }));
app.use(function(reqres) {
  // Save variable to session. 
  req.session.foo = 'bar';
var httpServer = http.createServer(app).listen(5000);
var server = eio.attach(httpServer);
server.on('connection', eioSession({
  cookieParser: cookieParser,
  store: sessionStore,
  key: sessionKey,
  secret: sessionSecret
server.on('session', function(socketsession) {
  // Receive variable from session. 
  console.log(session.foo); // bar 

Same as above. Replace connect with express.
