Cache

中文说明

Generic cache use and cache manager for golang.

Provide a unified usage API by packaging various commonly used drivers.

All cache driver implemented the cache.Cache interface. So, You can add any custom driver.

Packaged Drivers:

• goredis https://github.com/go-redis/redis
• redis https://github.com/gomodule/redigo
• memcached https://github.com/bradfitz/gomemcache
• buntdb https://github.com/tidwall/buntdb
• boltdb https://github.com/etcd-io/bbolt
• badger https://github.com/dgraph-io/badger
• nutsdb https://github.com/xujiajun/nutsdb
• goleveldb https://github.com/syndtr/goleveldb
• gcache https://github.com/bluele/gcache
• gocache https://github.com/patrickmn/go-cache
• bigcache https://github.com/allegro/bigcache

Internal:

• file internal driver driver_file.go
• memory internal driver driver_memory.go

Notice: The built-in implementation is relatively simple and is not recommended for production environments; the production environment recommends using the third-party drivers listed above.

Install

The package supports 3 last Go versions and requires a Go version with modules support.

go get github.com/gookit/cache

Cache Interface

All cache driver implemented the cache.Cache interface. So, You can add any custom driver.

type Cache interface {
	// basic operation
	Has(key string) bool
	Get(key string) interface{}
	Set(key string, val interface{}, ttl time.Duration) (err error)
	Del(key string) error
	// multi operation
	GetMulti(keys []string) map[string]interface{}
	SetMulti(values map[string]interface{}, ttl time.Duration) (err error)
	DelMulti(keys []string) error
	// clear and close
	Clear() error
	Close() error
}

Usage

package main

import (
	"fmt"

	"github.com/gookit/cache"
	"github.com/gookit/cache/gcache"
	"github.com/gookit/cache/gocache"
	"github.com/gookit/cache/goredis"
	"github.com/gookit/cache/redis"
)

func main() {
	// register one(or some) cache driver
	cache.Register(cache.DvrFile, cache.NewFileCache(""))
	// cache.Register(cache.DvrMemory, cache.NewMemoryCache())
	cache.Register(gcache.Name, gcache.New(1000))
	cache.Register(gocache.Name, gocache.NewGoCache(cache.OneDay, cache.FiveMinutes))
	cache.Register(redis.Name, redis.Connect("127.0.0.1:6379", "", 0))
	cache.Register(goredis.Name, goredis.Connect("127.0.0.1:6379", "", 0))

	// setting default driver name
	cache.DefaultUse(gocache.Name)

	// quick use.(it is default driver)
	//
	// set
	cache.Set("name", "cache value", cache.TwoMinutes)
	// get
	val := cache.Get("name")
	// del
	cache.Del("name")

	// get: "cache value"
	fmt.Print(val)

	// More ...
	// fc := cache.Driver(gcache.Name)
	// fc.Set("key", "value", 10)
	// fc.Get("key")
}

With Options

gords := goredis.Connect("127.0.0.1:6379", "", 0)
gords.WithOptions(cache.WithPrefix("cache_"), cache.WithEncode(true))

cache.Register(goredis.Name, gords)

// set
// real key is: "cache_name"
cache.Set("name", "cache value", cache.TwoMinutes)

// get: "cache value"
val := cache.Get("name")
