how to use sessions in express, couchDB, and node.js

Question

so I basically want to use sessions to store the users name and check to see if the user logged in or not. If not, the page will redirect to the login page.

I am using Node.js,express,and couchDB.

Here is how i set up my session so far

var MemoryStore = require('connect').session.MemoryStore; app.use(express.cookieParser()); app.use(express.session({      secret: "keyboard cat",      store: new MemoryStore({          reapInterval: 60000 * 10     }) })); 

To store something in the session, i use the following code right?

req.session = {user:name); 

So the session variable seems to work on my login page. I successfully store the user's name into the session However, when I try to access the session variable on another page, it gives me the error

Cannot read property 'user' of undefined 

all i'm doing is:

if (req.session.user){ 

Why is this error happening? are sessions not global to the whole app? Or am I missing something entirely here.

Thanks in advance!

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

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.
