Since connect doesn't use the parseCookie method anymore, how can we get session data using express?

Question

In node.js and express, there are many examples showing how to get session data.

• Node.js and Socket.io
• Express and Socket.io - Tying it all Together<

Answer 1

Your questions:

1. How can I update/change a cookie through RedisStore?
2. It looks like session data is saved only in cookies. How can I keep track of user information from page to page if someone has cookies turned off?

Cookies / Sessions / RedisStore Thoughts:

1. Typically, you have exactly one cookie, which is the session id
2. All user-state is stored on the server in a "session" which can be found via the session id
3. You can use Redis as your back-end storage for your session data.
4. Redis will allow you to keep session state, even when your server is restarted (good thing)
5. You can store a mountain of data in your session (req.session.key = value)
6. All data stored in the session will be persistant until the user logs out, or their session expires

Example node.js Code:

var app = express.createServer(
  express.static(__dirname + '/public', { maxAge: 31557600000 }),
  express.cookieParser(),
    express.session({ secret: 'secret', store: new RedisStore({
          host: 'myredishost',
          port: 'port',
          pass: 'myredispass',
          db: 'dbname',
      }, cookie: { maxAge: 600000 })})
);

Session and Cookie Thoughts:

1. Your second issue us about sessions without cookies. This is possible.
2. You, basically, put the session id on the url of every request you send to the server.
3. I strongly believe that most people allow cookies.
4. If this is a requirement, google: "session without cookies"
