Express Session RethinkDB

RethinkDB session store for Express 4.x

Installation

# yarn:
yarn add @geo1088/express-session-rethinkdb
# npm:
npm install --save @geo1088/express-session-rethinkdb

Dependencies

• express-session (duh)
• rethinkdbdash for connecting to RethinkDB. The official driver is not supported.

Without an existing database connection

var express = require('express');
var session = require('express-session');
var RDBStore = require('express-session-rethinkdb')(session);

var app = express();
var rdbStore = new RDBStore({
  connectOptions: {
    servers: [
      { host: '192.168.0.100', port: 28015 },
      { host: '192.168.0.101', port: 28015 },
      { host: '192.168.0.102', port: 28015 }
    ],
    db: 'test',
    discovery: false,
    pool: false,
    buffer: 50,
    max: 1000,
    timeout: 20,
    timeoutError: 1000
  },
  table: 'session',
  sessionTimeout: 86400000,
  flushInterval: 60000,
  debug: false
});

app.use(session({
  key: 'sid',
  secret: 'my5uperSEC537(key)!',
  cookie: { maxAge: 860000 },
  store: rdbStore
}));

// the rest of your server code..

With an existing connection

const express = require('express');
const session = require('express-session');
const RDBStore = require('express-session-rethinkdb')(session);

const r = require('rethinkdbdash')({
  // Your database configuration...
  db: "test"
})

const app = express();
const rdbStore = new RDBStore({
  // Pass a reference to your existing connection here
  connection: r,
  // Other store configuration
  table: 'session',
  sessionTimeout: 86400000,
  flushInterval: 60000,
  debug: false
});

app.use(session({
  key: 'sid',
  secret: 'my5uperSEC537(key)!',
  cookie: { maxAge: 860000 },
  store: rdbStore
}));

// the rest of your server code..

TODO: there was a Thinky example here. I don't know what that is, so I removed it.

Constructor options

connection

rethinkdbdash connection instance. See RethinkDB's doc Also see rethinkdbdash

connectOptions

Options for connecting to the database server. (if connection is set connectOptions will be ignored) See RethinkDB's doc Also see rethinkdbdash

table

Name of the table in which session data will be stored. Default: 'session'

sessionTimeout

If you do not set cookie.maxAge in session middleware, sessions will last until the user closes their browser. However we cannot keep the session data infinitely (for size and security reasons). In this case, this setting defines the maximum length of a session, even if the user does not close their browser. Default: 86400000 1 day

flushInterval

RethinkDB does not yet provide an expiration function ( like SETEX for Redis ), so we have to remove the old expired sessions from the database intermittently. This is the time interval in milliseconds between flushing of expired sessions. Default: 60000 60 seconds
