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
Redis Cluster	github.com/no-src/nscache/redis_cluster	redis-cluster://127.0.0.1:7001?addr=127.0.0.1:7002&addr=127.0.0.1:7003
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
Memcached	github.com/no-src/nscache/memcached	memcached://127.0.0.1:11211
Proxy	github.com/no-src/nscache/proxy/client	proxy://127.0.0.1:8080

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
	}
}

Command Line Tool

You can use the command line tool to operate all the cache drivers that nscache supports.

Install the command line tool nscache-cli.

go install github.com/no-src/nscache/cmd/nscache-cli@latest

Run the cli tool with specified cache driver connection string to operate cache.

nscache-cli memory:

Proxy

Proxy Server

Install the proxy server nscache-server.

go install github.com/no-src/nscache/cmd/nscache-server@latest

Run the proxy server with specified listen address and cache driver connection string.

nscache-server -addr=:8080 -conn=memory:

Proxy Client

You can use the code to operate cache proxy server like the example code in the Quick Start section.

Or use the nscache-cli to connect to the proxy server and operate cache.

nscache-cli proxy://127.0.0.1:8080
