    <p>I am trying to implement a session store for an express.js node app My question are :</p> <ol> <li>How do you delete cookie that have a browser session lifetime (marked with expires = false according to connect doc)</li> <li>Should I store session data as a json string or directly as an object</li> </ol> <p>this is the coffee script I came up with so far, using mongoose as I this is the orm I chose for the app</p> <pre><code> express = require 'express' mongoose = require "mongoose" util = require "util" # define session schema SessionSchema = new mongoose.Schema sid : { type: String, required: true, unique: true } data : { type: String, default: '{}' } expires : { type: Date, index: true } module.exports = class SessionStore extends express.session.Store constructor: (options) -&gt; console.log "creating new session store" options ?= {} # refresh interval options.interval ?= 60000 options.url ?= "mongodb://localhost/session" # create dedicated session connection connection = mongoose.createConnection options.url # create session model @Session = connection.model 'Session', SessionSchema # remove expired session every cycles removeExpires = =&gt; @Session.remove expires: { '$lte': new Date() } setInterval removeExpires, options.interval get: (sid, fn) -&gt; @Session.findOne sid: sid, (err, session) -&gt; if session? try fn null, JSON.parse session.data catch err fn err else fn err, session set: (sid, data, fn) -&gt; doc = sid: sid data: JSON.stringify data expires: data.cookie.expires try @Session.update sid: sid, doc, upsert: true, fn catch err fn err destroy: (sid, fn) -&gt; @Session.remove { sid: sid }, fn all: (fn) -&gt; @Session.find { expires: { '$gte': new Date() } }, [ 'sid' ], (err, sessions) -&gt; if sessions? fn null, (session.sid for session in sessions) else fn err clear: (fn) -&gt; @Session.drop fn length: (fn) -&gt; @Session.count {}, fn </code></pre>

    1. COHave you seen [connect-mongo](https://github.com/kcbanner/connect-mongo)? It always grabs the session data from the DB by it's ID and destroys it on the client if needed (`if !expires or Date.now() < expires`), that looks like a reasonable solution.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
