zen-lru

zen-lru 是一个精简的 JavaScript 数据缓存库，使用最近最少使用 (LRU) 算法，摘自 Rasmus Andersson 的 js-lru。

思路：

     entry             entry             entry             entry
     ______            ______            ______            ______
    | head |.newer => |      |.newer => |      |.newer => | tail |
    |  A   |          |  B   |          |  C   |          |  D   |
    |______| <= older.|______| <= older.|______| <= older.|______|
removed  <--  <--  <--  <--  <--  <--  <--  <--  <--  <--  <--  added

安装

1npm install zen-lru

使用

1const Cache = require('zen-lru')
2
3const cache = new Cache(1000) // 参数 1000 用于限制缓存最大数量，可选，默认为 5000
4cache.set('a', {foo: 'bar'})
5cache.get('a') // {foo: "bar"}

特性

只实现了最常用的 get 和 set 方法
一律使用全等于（===）undefined 来判断数据是否存在
新增最大缓存数默认值：5000
get 方法第二个参数，默认开发者主动忽略
调用 set 方法时，如果超过了最大缓存数，不再返回被删除的数据
