Cache Store

Cache messages to a database table.

Installation

go get -u github.com/gouniverse/cachestore

Setup

cacheStore = cachestore.NewStore(NewStoreOptions{
	DB:                 db,
	CacheTableName:     "my_cache",
	AutomigrateEnabled: false,
	DebugEnabled: false,
})

go cacheStore.ExpireCacheGoroutine()

Usage

• Set value to cache with expiration

isSaved, err := cacheStore.Set("token", "ABCDEFGHIJKLMNOPQRSTVUXYZ", 60*60) // 1 hour (= 60 min * 60 sec)
if isSaved == false {
	log.Println("Saving failed")
	return
}

• Get value from cache with default if not found

token, err := cacheStore.Get("token", "") // "" - default value, if the key has expired, or missing

• Set and retrieve complex value as JSON

isSaved, err := cacheStore.Set("token", map[string]string{"first_name": "Jo"}, 60*60) // 1 hour (= 60 min * 60 sec)
if isSaved == false {
	log.Println("Saving failed")
	return
}

value, err := store.GetJSON("hello", "")

if err != nil {
	log.Fatalf("Getting JSON failed:" + err.Error())
}

result := value.(map[string]interface{})

log.Println(result["first_name"])
