API

aedesPersistenceRedis([opts])

Creates a new instance of aedes-persistence-redis. It takes all the same options of ioredis, which is used internally to connect to Redis.

This constructor creates two connections to Redis.

Example:

aedesPersistenceRedis({
  port: 6379,          // Redis port 
  host: '127.0.0.1',   // Redis host 
  family: 4,           // 4 (IPv4) or 6 (IPv6) 
  password: 'auth',
  db: 0,
  maxSessionDelivery: 100, // maximum offline messages deliverable on client CONNECT, default is 1000 
  packetTTL: function (packet) { // offline message TTL, default is disabled 
    return 10 //seconds 
  }
})
