Redis client for UnityBase
Limitations
For simplicity current implementation uses a single redis instance
Usage
Can be used from command line - see apps/autotest/scripts/redis_sample.js, or from server worker as in example
const redis = require('@unitybase/redis')
const redisConn = redis.getDefaultRedisConnection()
// Set key `key1` to hold the string value `val1` with 3 second expire
redisConn.commands('set', 'key1', 'val1', 'EX', 3)
// get time-to-live (TTL0 of key1
const TTL = redisConn.commands('TTL', 'key1')
console.log('key1 will live', TTL, 'sec')
// get value
let val = redisConn.commands('get', 'key1')
console.log('Value for key1 is', val)
console.log('Waiting for 3 second...')
sleep(3100)
// now value is expired
val = redisConn.commands('get', 'key1')
console.log('Expired value for key1 is', val) // val is null
