[root@namenode mongodb]# ./bin/mongo MongoDB shell version: 1.8.2 connecting to: test > use test; switched to db test
To store or access session data, simply use the request property req.session, which is (generally) serialized as JSON by the store, so nested objects are typically fine.
var express = require('express'); var session = require('express-session'); var cookieParser = require('cookie-parser'); var MongoStore = require('connect-mongo')(session); var app = express();
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.
