Connect Session Store using Sequelize
connect-session-sequelize is a SQL session store using Sequelize.js.
Installation
Please note that the most recent version requires express 4. If you use express 3 you should install version 0.0.5 and follow the instructions in the previous README.
$ npm install connect-session-sequelize
Options
db
a successfully connected Sequelize instancetable
(optional) a table/model which has already been imported to your Sequelize instance, this can be used if you want to use a specific table in your dbextendDefaultFields
(optional) a way add custom data to table columns. Useful if using a custom model definition
Usage
With connect
var connect = require('connect')
// for express, just call it with 'require('express-session').Store'
, SequelizeStore = require('connect-session-sequelize')(connect.session.Store);
connect().use(connect.session({
store: new SequelizeStore(options)
, secret: 'CHANGEME'
}));
With express 4:
// load dependencies
var express = require('express')
var Sequelize = require('sequelize')
var cookieParser = require('cookie-parser')
var session = require('express-session');
// initalize sequelize with session store
var SequelizeStore = require('connect-session-sequelize')(session.Store);
// create database, ensure 'sqlite3' in your package.json
var sequelize = new Sequelize(
"database",
"username",
"password", {
"dialect": "sqlite",
"storage": "./session.sqlite"
});
// configure express
var app = express()
app.use(cookieParser())
app.use(session({
secret: 'keyboard cat',
store: new SequelizeStore({
db: sequelize
}),
resave: false, // we support the touch method so per the express-session docs this should be set to false
proxy: true // if you do SSL outside of node.
}))
// continue as normal
SequelizeStore.sync()
- will run a sequelize sync()
operation on the model for an initialized SequelizeStore object. Use this if you would like the the db table to be created for you.
Session expiry
Session records are automatically expired and removed from the database on an interval. The cookie.expires
property is used to set session expiry time. If that property doesn't exist, a default expiry of 24 hours is used. Expired session are removed from the database every 15 minutes by default. That interval as well as the default expiry time can be set as store options:
new SequelizeStore({
...
checkExpirationInterval: 15 * 60 * 1000, // The interval at which to cleanup expired sessions in milliseconds.
expiration: 24 * 60 * 60 * 1000 // The maximum age (in milliseconds) of a valid session.
});
Add custom field(s) as a column
The extendDefaultFields
can be used to add custom fields to the session table. These fields will be read-only as they will be inserted only when the session is first created as defaults
. Make sure to return an object which contains unmodified data
and expires
properties, or else the module functionality will be broken:
var Session = sequelize.define('Session', {
sid: {
type: Sequelize.STRING,
primaryKey: true
},
userId: Sequelize.STRING,
expires: Sequelize.DATE,
data: Sequelize.STRING(50000)
});
function extendDefaultFields(defaults, session) {
return {
data: defaults.data,
expires: defaults.expires,
userId: session.userId
};
}
var store = new SessionStore({
db: sequelize,
table: 'Session',
extendDefaultFields: extendDefaultFields
});
