connect-memcached

Memcached session store, using node-memcached for communication with cache server.

Installation

via npm:

$ npm install connect-memcached

Example

var express      = require('express')
, session        = require('express-session')
, cookieParser   = require('cookie-parser')
, http           = require('http')
, app            = express()
, MemcachedStore = require('connect-memcached')(session);

app.use(cookieParser());
app.use(session({
      secret  : 'CatOnKeyboard'
    , key     : 'test'
    , proxy   : 'true'
    , store   : new MemcachedStore({
        hosts: ['127.0.0.1:11211'],
        secret: '123, easy as ABC. ABC, easy as 123' // Optionally use transparent encryption for memcache session data
    })
}));

app.get('/', function(req, res){
    if(req.session.views) {
        ++req.session.views;
    } else {
        req.session.views = 1;
    }
    res.send('Viewed <strong>' + req.session.views + '</strong> times.');
});

http.createServer(app).listen(9341, function() {
    console.log("Listening on %d", this.address().port);
});

Options

  • hosts Memcached servers locations, can be string, array, hash.
  • prefix An optional prefix for each memcache key, in case you are sharing your memcached servers with something generating its own keys.
  • ttl An optional parameter used for setting the default TTL (in seconds)
  • secret An optional secret can be used to encrypt/decrypt session contents.
  • algorithm An optional algorithm parameter may be used, but must be valid based on returned crypto.getCiphers(). The current default is aes-256-ctr and was chosen based on the following information
  • ... Rest of given option will be passed directly to the node-memcached constructor.

For details see node-memcached.
