Installing persistence.js on node is easy using npm:
npm install persistencejs
Alternatively, you can clone the repository manually:
git clone git://github.com/zefhemel/persistencejs.git
If installed manually, you also need to install node-mysql, the MySQL driver that the persistence store depends on.
Setup
You need to require two modules, the persistence.js library itself and the store module.
var persistence = require('persistencejs/persistence').persistence;
// For MySQL:
var persistenceStore = require('persistencejs/persistence.store.mysql');
// For SQLite:
var persistenceStore = require('persistencejs/persistence.store.sqlite');
Alternatively, if you cloned persistence.js using git, use a relative path to the modules instead, e.g.:
var persistence = require('./persistencejs/persistence').persistence;
var persistenceStore = require('./persistencejs/persistence.store.mysql');
// or
var persistenceStore = require('./persistencejs/persistence.store.sqlite');
Then, you configure the database settings to use:
// MySQL
persistenceStore.config(persistence, 'localhost', 3306, 'dbname', 'username', 'password');
// SQLite
persistenceStore.config(persistence, __dirname + '/mydb.db');
Subsequently, for every connection you handle (assuming you’re building a sever), you call the persistenceStore.getSession() method:
var session = persistenceStore.getSession();
