'session' is undefined when using express / redis for session store

Question

I\'m trying to use redis for sessions in my express app.

I do the following:

var express = require(\'express\');
var RedisStore = require(\'connect-r         


        

Answer 1

Things have changed recently with Express 3 / Express 4. Please confirm you are using version 4.

The complete middleware concept changed. You need to install these middlewares manually. "express-session" is one of the 4.0 middlewares.

I recommend to read

http://scotch.io/bar-talk/expressjs-4-0-new-features-and-upgrading-from-3-0 and https://github.com/visionmedia/express/wiki/Migrating-from-3.x-to-4.x

Additionally some users were confused that the github repo itself is named just "session" but

npm install express-session

is correct.
