Node-redis-session NPM

Express-Redis-Session

This is a node Express middleware to store session into redis.

Install with:

$npm install node-redis-session

Usage

var express = require('express');
var cookieParser = require('cookie-parser');
var redisSession = require('node-redis-session');
var app = express();

app.use(cookieParser());
app.use(redisSession());

app.get('/', function(req, res) {
	
  //just use req.session and it will be there,
  //when next same browser request come.
  if (!req.session.user) {
    req.session.user = {name: 'anonymous'};
  }
    
  res.end('hello '+req.session.user.name);
});

app.listen(3000);

Session will be store in redis, as JSON.stringify(req.session). You can find it with redis command line.

redisSession(options)

Other way to establish a redisSession is:

var express = require('express');
var cookieParser = require('cookie-parser');
var redisSession = require('node-redis-session');
var app = express();

app.use(cookieParser());
app.use(redisSession({ cookieName: 'mySessionid' }));

So cookie-name in browser will be set as mySessionid. It's useful when multi projects are use redisSession. Do this and escape projects from use same cookie-name.

Options

redisOptions: configure redis, must be a array. ex: [6379, 'localhost', {auth_pass: 'auth_pass'}]
redisClient: redis client, if exists ignore redisOptions.
cookieName: overwrite default cookie name, useful in multi products.
expireTime: cookie expire time in browser / session expire time in redis. count with ms.
cacheCookieName: multi application use sso will hold same session. and use this to hold a cache in single app. usage: req.cache.
cookieOptions: see third param in http://expressjs.com/zh-cn/api.html (search res.cookie). // Object.assign({expires, httpOnly}, cookieOptions);
