NPM Version js-standard-style

Redis session middleware for Telegraf

Original: telegraf-session-redis

Updated for the new version of Telegraf

Installation

$ npm install telegraf-session-redis-upd

Example

const Telegraf = require('telegraf')
const RedisSession = require('telegraf-session-redis-upd')

const bot = new Telegraf(process.env.BOT_TOKEN)

const session = new RedisSession({
  store: {
    host: process.env.TELEGRAM_SESSION_HOST || '127.0.0.1',
    port: process.env.TELEGRAM_SESSION_PORT || 6379
  }
})

bot.use(session)

bot.on('text', (ctx) => {
  ctx.session.counter = ctx.session.counter || 0
  ctx.session.counter++
  console.log('Session', ctx.session)
})

bot.launch()

When you have stored the session key beforehand, you can access a session without having access to a context object. This is useful when you perform OAUTH or something similar, when a REDIRECT_URI is called on your bot server.

const redisSession = new RedisSession()

// Retrieve session state by session key
redisSession.getSession(key)
  .then((session) => {
    console.log('Session state', session)
  })

// Save session state
redisSession.saveSession(key, session)

API

Options

  • store:
  • property: context property name (default: session)
  • ttl: session ttl in seconds (default: forever)
  • getSessionKey: session key resolver function (ctx) => any)

Default implementation of getSessionKey:

function getSessionKey (ctx) {
  if (!ctx.from || !ctx.chat) {
    return
  }
  return `${ctx.from.id}:${ctx.chat.id}`
}

Destroying a session

To destroy a session simply set it to null.

bot.on('text', (ctx) => {
  ctx.session = null
})
