simple-cache-nodejs

nodejs 简单的无侵入式内存缓存框架

安装

npm install --save simple-cache-z

用法

const cache = require('simple-cache-z').cache;
// 定义 cacheKey
function cachekey(args) {
    return args[0]
}
// 你需要缓存的方法
function request(key) {
    return (new Date()).getTime();
}
// 缓存时间 5000 ms
const cacheTime = 5 * 1000
// 应用缓存
request = cache(request, cachekey, 5000);
// 使用
// 用法不变，不需要添加缓存代码
request("abc", "def")

测试代码

console.log('request 1 ', request(1));
setTimeout(() => {
    console.log('request 2 ', request(2));
}, 1000)
setTimeout(()=> {
    console.log('request 1 ', request(1));
    console.log('request 1 ', request(1));
    console.log('request 1 ', request(1));
    console.log('request 2 ', request(2));
    console.log('request 2 ', request(2));
    console.log('request 2 ', request(2));
}, 2000);
setTimeout(()=> {
    console.log('request 1 ', request(1));
    console.log('request 1 ', request(1));
    console.log('request 1 ', request(1));
    console.log('request 2 ', request(2));
    console.log('request 2 ', request(2));
    console.log('request 2 ', request(2));
}, 10000);
