connect-mysql

connect-mysql

This is a simple MySQL backed session store for connect.

It uses the node-mysql module already installed in your project to establish and pool connections.

Options

  • table: the name of the database table that should be used for storing sessions. Defaults to 'sessions'
  • pool: a node-mysql connection pool or true if the store should instantiate its own pool
  • config: the configuration that will be passed to createConnection() or createPool() if pool is true
  • retries: how many times to retry connecting to the database before failing. Defaults to 3
  • keepalive: keep pooled connections open by periodically pinging them. Set to true to use the default interval of 30000 ms or provide a positive number to set your own. Defaults to true.
  • cleanup: a boolean specifying whether to enable the cleanup events. note that if this is disabled, cleanup will not take place at all and should be done externally. Sessions with an expiration time of 0 will always be ignored and should also be cleaned up externally.
  • secret: key that will be used to encrypt session data. If this option is not provided then data will be stored in plain text
  • algorithm: the algorithm that should be used to encrypt session data. Defaults to 'aes-256-ctr'

Examples

Here are some example use cases to get your application up and running.

Default use case

Simple use case using the express framework & connect-session middleware with connect-mysql as the data store.

var express = require('express'),
    session = require('connect-session'),
    MySQLStore = require('connect-mysql')(session),
    options = {
      config: {
        user: 'dbuser', 
        password: 'dbpassword', 
        database: 'db' 
      }
    };
 
var app = express.createServer();
 
app.use(express.cookieParser());
app.use(express.session({
  secret: 'supersecretkeygoeshere',
  store: new MySQLStore(options))
});

Connection pooling example

For those MySQL installations that make use of pools the following examples are available.

  var mysql = require('mysql'),
      options = {
        pool: mysql.createPool({
          user: 'dbuser',
          password: 'dbpassword',
          database: 'db'
        })
      };

Or

var options = {
      pool: true,
      config: {
        user: 'dbuser', 
        password: 'dbpassword', 
        database: 'db' 
      }
    };

Ssession encryption example

This option enables transparent session encryption assisting

var options = {
      secret: 'thesessionsecret',
      config: {
        user: 'dbuser', 
        password: 'dbpassword', 
        database: 'db' 
      }
   };
