connect-mongo

MongoDB session store for Connect (can use replica set with mongo)

Installation

mongo-session supports only connect >= 1.0.3.

via npm:

$ npm install mongo-session

Options

dbobj: null,    /*Mongo Replica set or Db(object)(if ==null please set (host/port)config)*/
host: '127.0.0.1',
port: 27017,
stringify: true,
collection: 's_sessions',
auto_reconnect: false,
native_parser: false,
w: 1

Example

With express:

ReplSet

var mongodb = require('mongodb') , Db = mongodb.Db , Server = mongodb.Server , ReplSet = mongodb.ReplSet; var replSet = ReplSet( [ new Server("1270.0.0.1", 27017, { auto_reconnect: true }), // Primary new Server("1270.0.0.1", 27027, { auto_reconnect: true }), // Secondary new Server("1270.0.0.1", 27037, { auto_reconnect: true }) // Secondary ], { rs_name: "imchat", read_secondary: true } ); var dbs = new Db("imchatdb", replSet, { native_parser: true, w: 1 });

var storeMongo = new MongoStore({ dbobj: dbs, /Mongo Replica set or Db(object)/ //db: settings.db, //host: settings.dbhost, //port: settings.dbport, collection: "s_session", native_parser: true

}, function () { console.log('connect mongodb success...'); }, null);

With connect:

var connect = require('connect');
var MongoStore = require('mongo-session')(connect);

Removing expired sessions

mongo-session uses MongoDB's TTL collection feature (2.2+) to have mongod automatically remove expired sessions. (mongod runs this check every minute.)

Note: By connect/express's default, session cookies are set to expire when the user closes their browser (maxAge: null). In accordance with standard industry practices, mongo-session will set these sessions to expire two weeks from their last 'set'. You can override this behavior by manually setting the maxAge for your cookies -- just keep in mind that any value less than 60 seconds is pointless, as mongod will only delete expired documents in a TTL collection every minute.
