内存缓存 in-memory cache

how to use

const Cache = require('@poseidon/runtime-cache')

const runtimeCache = new Cache({
    debug: false,
    max: 100,
    overcut: 10         // 溢出时，需要清除的缓存百分比
})

API

get(key) 获取

let cache = runtimeCache.get('aaa')

判断过期后的处理

// 在 controller 中使用
if (cache && cache.expired && !cache.fetching) {
    cache.fetching = true
    await apiService()
    cache.fetching = false
}

set(key, value, duration) 设置

runtimeCache.set('aaa', {b:1,c:1}, 60)

注：过期时间单位为秒

remove(key) 移除

runtimeCache.remove('aaa')

clear 清除

runtimeCache.clear()
