simplecache is an in-memory key:value store/cache

Any object can be stored, for a given duration or forever, and the cache can be safely used by multiple goroutines.

Installation

go get github.com/xsean2020/simplecache-go

Usage

import (
	"fmt"
	simplecache "github.com/xsean2020/simplecache-go"
	"time"
)

func main() {
	// Create a cache with a default expiration time of 5 minutes, and which
	// purges expired items every 10 minutes
    // Key must be compareble , value is any
	c := simplecache.New[string,any](5*time.Minute, 10*time.Minute)
	// Set the value of the key "foo" to "bar", with the default expiration time
	c.Set("foo", "bar", simplecache.DefaultExpiration)
    // Set value with default ttl 
	c.Add("baz", 42, simplecache.DefaultExpiration)

	// Get the string associated with the key "foo" from the cache
	foo, found := c.Get("foo")
	if found {
		fmt.Println(foo)
	}

	foo, found := c.Get("foo")
	if found {
		MyFunction(foo.(string))
	}

	// foo can then be passed around freely as a string
     c1 :=  simplecache.New[string,string](5*time.Minute, 10*time.Minute)
     c1.Set("foo", "foovalue", cache.DefaultExpiration)
     x, found := c2.Get("foo") // x is string type

     c2 :=  simplecache.New[string,*MyStruct](5*time.Minute, 10*time.Minute)
     c2.Set("foo", &MyStruct, cache.DefaultExpiration)
     x, found := c2.Get("foo") // X is *Mystruct type
