Session file store for Express and Connect. Also you can use it with Koa

Session file store is a provision for storing session data in the session file

• Supports Express >= 4.x and Connect >= 1.4.0 through express-session
• Supports Node.js >= 0.10 and io.js
• Indirectly supports Koa >= 0.9.0 through express-session

$ npm install session-file-store

$ npm install
$ npm test

• path The directory where the session files will be stored. Defaults to ./sessions
• ttl Session time to live in seconds. Defaults to 3600
• retries The number of retries to get session data from a session file. Defaults to 5
• factor The exponential factor to use for retry. Defaults to 1
• minTimeout The number of milliseconds before starting the first retry. Defaults to 50
• maxTimeout The maximum number of milliseconds between two retries. Defaults to 100
• reapIntervalObject [OUT] Contains intervalObject if reap was scheduled
• reapInterval Interval to clear expired sessions in seconds or -1 if do not need. Defaults to 1 hour
• reapAsync use distinct worker process for removing stale sessions. Defaults to false
• reapSyncFallback reap stale sessions synchronously if can not do it asynchronously. Default to false
• logFn log messages. Defaults to console.log
• fallbackSessionFn returns fallback session object after all failed retries. No defaults
• encrypt Enables encryption of the session before writing the file and also decryption when reading it.

Due to express >= 4 changes, we need to pass express-session to the function session-file-store exports in order to extend session.Store:

var session = require('express-session');
var FileStore = require('session-file-store')(session);

app.use(session({
    store: new FileStore(options),
    secret: 'keyboard cat'
}));
