Redis

This module wraps helper functions around ioredis to simplify development

• Requires

ioredis

• Basic Initialization - default client options, cluster support for AWS elasticache enabled

const Redis = require('@kelchy/redis')
const redis = new Redis(process.env.REDIS_URI)

• Basic Initialization - custom client option, cluster support disabled i.e. redis labs

const redis = new Redis(process.env.REDIS_URI, { cluster: false })

• Custom client options - cluster support for AWS elasticache turned off

const redisOptions = Redis.clientOptions()
const redis = new Redis(process.env.REDIS_URI, { redisOptions })

• Use pubsub

const redis = new Redis(process.env.REDIS_URI, { pubsub: true })

• Turn internal logging on

const Log = require('@kelchy/log')
const redis = new Redis(process.env.REDIS_URI, { redisOptions: Redis.clientOptions('password'), log: new Log.Standard() })

• supported methods

lock(key, ttl, options)
unlock(key, options)
set(key, value, options)
del(key)
hset(key, hkey, hvalue, options)
hdel(key, hkey)
hmset(key, obj, options)
mset(obj, options)
incr(key, options)
hincrby(key, hkey, hvalue, options)
rpush(key, list, options)
lrem(key, count, element, options)
sadd(key, list, options)

ttl(key)
keys(wildcard)
get(key)
hgetall(key)
lrange(key, lmin, lmax, options)
smembers(key)

subscribe(chan)
publish(chan, msg)

clientOptions(password) - returns client options which can be used during initialization - 'password' is string
result(value) - retrieves the last result from a write operation result - 'value'
