NodeJS: I can't make connect-redis work with express

Question

This is my code :

var express = require('express');
var RedisStore = require('connect-redis')(express);

And this is the error I get :

  RedisStore.prototype.__proto__ = Store.prototype;
                                        ^
TypeError: Cannot read property 'prototype' of undefined

Please help

Answer 1

Looks like they've addressed this in their docs:

Due to express 4.x.x changes, we now need to pass express-session to the function connect-redis exports in order to extend express-session.Store:

var session = require('express-session') , RedisStore = require('connect-redis')(session);

app.use(session({ store: new RedisStore(options), secret: 'keyboard cat' }))

Answer 2

1) remove express from node_modules

2) clean the cache (npm cache clean)

3) install the last version via package.json (*) or npm install

4) install connect-redis via package.json or npm install

5) Use:

, session = require('express-session') , RedisStore = require("connect-redis")(session);
