Package go-cache is an in-memory key-value store where keys expire after a period of time.
The Cache type provides Get and Set methods. The cache is goroutine safe.
Values are stored as type interface{}. You will need to use a type assertion after retrieval to use the typed value.
package main
var (
appCache *cache.Cache
once sync.Once
)
func setup() {
once.Do(func() {
appCache = cache.New(time.Hour * 1)
})
}
func main() {
setup()
appCache.Set("key", 1)
v, found := appCache.Get("key")
if found && v.(int) == 1 {
fmt.Println("success")
}
}
