A simple node.js cache manage system

Why I wrote this cache module and its advantages

http://qingbob.com/built-cache-management-module-in-nodejs/ (In Simplified Chinese)

How to use

Init

Cache.createCache([cache algorithm], [cache size])

• About cache algorithm: you have two choice "LRU" or "LFU", of course you can add your own algorithm. If you not sure which algorithm, you can choose the following manage mode.

var cache = require("Cache");
Cache.createCache("LRU", 100 * 100 * 10);

Set

cache.set(key, value[, expire(millisecond)])

cache.set("key", "value", 1000 * 60);

Get

cache.get(key)

cache.get("key") // value or null

Clear

cache.clear()

Manage Mode

If you are not sure which cache replacement algorithm is you need, you can try this model, it will caculate the recently 100 * 100 * 3 get hit rate in different algorithm.And according the hit rate choose the higher algorithm one:

var CacheManage = require("./Manage");
CacheManage.set("key", "value", 1000 * 60);

请问这个能缓存js,css么

node 对内存使用有限制，如何破？

node 对内存使用有限制，cache的数据不会超过１Ｇ，这个怎么破？？

几个小建议:1）避免O(N)操作；2）增加delete接口；3）TTL on get

Golang Version

Hi hh54188,
我昨天看到你的blog和这个项目，设计的非常优雅。

我这段时间正好在学习golang，go 上面没有很好的 cache， 所以从昨天开始，我参照你的项目 写了个 golang 版本的。

这是地址: gogo-cache

已经把您的项目挂在 gogo-cache 的主页上说明来历

感谢您写了这么棒的项目 👍

补充设计思路

这个算法讲解很到位，发现 wiki 可以编辑，于是补充了设计思路：

作者是否可以把设计思路放到 README.md 的链接中？
