toa-session

Session middleware for toa, inspired by generic-session.

toa

Demo

use as middleware:

const Toa = require('toa')
const session = require('toa-session')()

const app = new Toa()
app.use(function () {
  if (this.path === '/favicon.ico') return
  if (this.path === '/delete') this.session = null
  else this.session.name = 'test'

  this.body = {
    path: this.path,
    session: this.session,
    sessionId: this.sessionId
  }
})

app.use(session)
app.listen(3000)

use as module:

const Toa = require('toa')
const session = require('toa-session')()

const app = new Toa()(function *() {
  if (this.path === '/favicon.ico') return
  yield session

  if (this.path === '/delete') this.session = null
  else this.session.name = 'test'

  this.body = {
    path: this.path,
    session: this.session,
    sessionId: this.sessionId
  }
})

app.listen(3000)

• After adding session middleware, you can use this.session to set or get the sessions.
• Setting this.session = null; will destroy this session.

Installation

npm install toa-session

API

const session = require('toa-session');

app.use(session([options]))

• options.key: String, cookie name, default to toa.sid.

• options.store: object, session store instance.

• options.ttl: Number, store ttl in ms, default to 24 * 60 * 60 * 1000.

• options.prefix: String, session prefix for store, default to toa:sess:.

• options.cookie: Object, session cookie settings.

• options.rolling: Boolean, rolling session, always reset the cookie and sessions, default to false.

• options.sidSize: Number, random bytes's length to generate sid, sid included timestamp hash and CRC bytes, so it's length is long than sidSize, default to 24.

• options.genSid: Function, you can use your own generator for sid, default to ./lib/sid.js.

• Store can be any Object that has the methods set, get, destroy like memoryStore.

• cookie defaulting to

const defaultCookie = {
  httpOnly: true,
  path: '/',
  overwrite: true,
  signed: true,
  maxAge: 24 * 60 * 60 * 1000 // ms
};

Session Store

You can use any other store to replace the default MemoryStore, it just needs to follow this api:

• get(sid): get session object by sid
• set(sid, session, ttl): set session object for sid, with a ttl (in ms)
• destroy(sid): destory session for sid

the api needs to return a Promise, Thunk or generator.

And use these events to report the store's status.

• connect
• disconnect
