connect-mongo

MongoDB session store for Connect

Installation

connect-mongo supports only connect >= 1.0.3.

via npm:

$ npm install connect-mongo

Options

• db Database name OR fully instantiated node-mongo-native object
• collection Collection (optional, default: sessions)
• host MongoDB server hostname (optional, default: 127.0.0.1)
• port MongoDB server port (optional, default: 27017)
• username Username (optional)
• password Password (optional)
• auto_reconnect This is passed directly to the MongoDB Server constructor as the auto_reconnect option (optional, default: false).
• ssl Use SSL to connect to MongoDB (optional, default: false).
• url Connection url of the form: mongodb://user:pass@host:port/database/collection. If provided, information in the URL takes priority over the other options.
• mongoose_connection in the form: someMongooseDb.connections[0] to use an existing mongoose connection. (optional)
• stringify If true, connect-mongo will serialize sessions using JSON.stringify before setting them, and deserialize them with JSON.parse when getting them. (optional, default: true). This is useful if you are using types that MongoDB doesn't support.

The second parameter to the MongoStore constructor is a callback which will be called once the database connection is established. This is mainly used for the tests, however you can use this callback if you want to wait until the store has connected before starting your app.

Example

With express4:

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

app.use(session({
    secret: settings.cookie_secret,
    store: new MongoStore({
      db : settings.db,
    })
  }));

With express<4:

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

app.use(express.session({
    secret: settings.cookie_secret,
    store: new MongoStore({
      db: settings.db
    })
  }));

With connect:

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

Removing expired sessions

connect-mongo 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, connect-mongo 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.

Tests

You need mocha.

make test

The tests use a database called connect-mongo-test.
