Getting Started

Use cache.Cache interface type

var mycache cache.Cache

Create local cache(use sync.Map as a cache storage):

mycache = cache.Local{ExpireTime: time.Hour * 24}

Create redis cache

redisConn := "redis://127.0.0.1:6379"
mycache = cache.NewRedis(redisConn)

• default expire time: time.Hour * 24
• default Converter: JsonConverter

Or, create redis cache with addiotional options:

redisConn := "redis://127.0.0.1:6379"
mycache = cache.NewRedis(redisConn,
        cache.WithExpireTime(time.Hour*3),
        cache.WithGobConverter(),
        func(redis *cache.Redis) {
                // setup additional options
        },
)

If you want to use GobConverter, you have to identify the concrete type of a value using gob.Register() function.

Save to cache:

loadFromCache, err := cache.LoadOrStore(key, &target, func() (interface{}, error) {
        // return your own result
        return "value", nil
})

Delete from cache:

cache.Delete(key)
