go-cache

This repository is a hard-fork of revel-cache

Motivation to do this:

• light-weight cache library that doesn't download the internet.
• Doesn't use background go-routines for expiration.
• Has both in-memory, Redis and more (to be introduced) backends.

Quick Start

Installation

$ go get github.com/oogway/go-cache

Usage

In-memory

Example:

package main

import (
	"fmt"
	"time"

	cache "github.com/oogway/go-cache"
)

func main() {
	// Use in-memory store
	store := cache.NewInMemoryCache(time.Hour)

	store.Set("key", "value", time.Hour)

	var value string
	// Set the item
	store.Get("key", &value)
	fmt.Println("Key:", value)

	store.Set("num", 1, time.Hour)
	var num int
	// Well, lets check it has set correct
	store.Get("num", &num)
	fmt.Println("Number: ", num)

	// No longer need the item in store? DELETE IT!
	store.Delete("key")

	// Update value
	// NOTE: Replace only works iff the key exists in store
	store.Replace("num", 100, time.Hour)
	store.Get("num", &num)
	fmt.Println("Replaced Number: ", num)

	// Get rid of all keys at once
	store.Flush()
}

Redis

For Redis store just initialize store as follows

store := cache.NewRedisCache(cache.RedisOpts{
    Host:       "",
    Expiration: time.Hour,
})

Empty host assumes redis service on local machine (localhost:6379)

Following are the options while initializing Redis store

    MaxIdle        int
    MaxActive      int
    Protocol       string
    Host           string
    Password       string
    Expiration     time.Duration
    TimeoutConnect int
    TimeoutRead    int
    TimeoutWrite   int
    TimeoutIdle    int
