session-file-store

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

Compatibility

• Supports Express >= 4.x and Connect >= 1.4.0 through express-session
• Supports Node.js >= 8
• Indirectly supports Koa >= 0.9.0 through express-session

Getting Started

Installation

$ npm install session-file-store

Running Tests

$ npm install
$ npm test

Options

• 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
• encoding Object-to-text text encoding. Can be null. Defaults to 'utf8'
• encoder Encoding function. Takes object, returns encoded data. Defaults to JSON.stringify
• decoder Decoding function. Takes encoded data, returns object. Defaults to JSON.parse
• fileExtension File extension of saved files. Defaults to '.json'
• secret Enables transparent encryption support conforming to OWASP's Session Management best practices.
• crypto.algorithm Defaults to aes-256-gcm but supports symmetric algorithms listed from crypto.getCiphers().
• crypto.hashing Defaults to sha512 but supports hashing algorithms listed from crypto.getHashes().
• crypto.use_scrypt Defaults to true. When not supported (node < 10.5) will fall back to the crypto.pbkdf2() key derivation function.

Usage

Express or Connect integration

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);

var fileStoreOptions = {};

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