Answer 1

If you're doing app.use(app.router) before the lines that set up the cookie and session handling, try moving it to after them. That fixed the same problem for me.

Answer 2

the sessionSecret in the configuration (config.json?) should be non-empty:

sessionSecret: "something other than an empty string",

Answer 3

I was trying to solve the exact same problem for he last few hour.

Try initializing your server like that:

var app = express.createServer(
express.cookieParser(),
express.session({ secret: "crazysecretstuff"})
  );

That should work.

Answer 4

I had same issue of getting undefined for session variable which I knew was set ok.

In my case it turned out to be caused by cross origin request, I had forgotten the withCredentials header on the request.

So for example in my client side Angular app I needed to do this:

var config = { withCredentials: true };
return $http.get(appConfig.apiUrl + '/orders', config);

and in Express this:

res.header('Access-Control-Allow-Credentials', true);
