Installation

go get -u github.com/no-src/nscache

Quick Start

First, you need to import the cache driver, then create your cache component instance with the specified connection string and use it.

Current support following cache drivers

Driver	Import Driver Package	Connection String Example
Memory	`github.com/no-src/nscache/memory`	`memory:`
Redis	`github.com/no-src/nscache/redis`	`redis://127.0.0.1:6379`
BuntDB	`github.com/no-src/nscache/buntdb`	`buntdb://:memory:` or `buntdb://buntdb.db`
Etcd	`github.com/no-src/nscache/etcd`	`etcd://127.0.0.1:2379?dial_timeout=5s`
BoltDB	`github.com/no-src/nscache/boltdb`	`boltdb://boltdb.db`
FreeCache	`github.com/no-src/nscache/freecache`	`freecache://?cache_size=50mib`
BigCache	`github.com/no-src/nscache/bigcache`	`bigcache://?eviction=10m`
FastCache	`github.com/no-src/nscache/fastcache`	`fastcache://?max_bytes=50mib`

For example, initial a memory cache and write, read and remove data.

package main

import (
	"time"

	_ "github.com/no-src/nscache/memory"

	"github.com/no-src/log"
	"github.com/no-src/nscache"
)

func main() {
	// initial cache driver
	c, err := nscache.NewCache("memory:")
	if err != nil {
		log.Error(err, "init cache error")
		return
	}
	defer c.Close()

	// write data
	k := "hello"
	c.Set(k, "world", time.Minute)

	// read data
	var v string
	if err = c.Get(k, &v); err != nil {
		log.Error(err, "get cache error")
		return
	}
	log.Info("key=%s value=%s", k, v)

	// remove data
	if err = c.Remove(k); err != nil {
		log.Error(err, "remove cache error")
		return
	}
}
