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

Note: session-file-store only supports express >= 4.0.0

  $ npm install session-file-store

• path The directory where the session files will be stored. Defaults to ./sessions
• ttl 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 Defaults to 1
• minTimeout Defaults to 50
• maxTimeout Defaults to 100
• reapInterval Interval to clear expired sessions in seconds. Defaults to 1 hour

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'
}));
