req.session undefined and req.session.user_id not working

Question

I am using Express and node for the session management with https. I want to create a session using express so that authentication and the session is made before the redirec

Answer 1

The session middleware checks if an incoming request matches the cookie path; if not, it doesn't bother continuing (and req.session won't even be created). In your situation, your cookie path is set to /public/, which doesn't match the request path /login.

I think you'd want to configure the session middleware cookie to use / as a path:

app.use(express.session({
  cookie: {
    path    : '/',
    httpOnly: false,
    maxAge  : 24*60*60*1000
  },
  secret: '1234567890QWERT'
}));
