Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

redis-cache ===========

Readme

redis-cache

node.js use redis to cache

#Usage

提供redis的缓冲,执行getCache函数后,将检查是否缓存里的键值是否有该值,如果没有,则执行目标函数,将缓冲函产生的参数,缓存到redis,为第二次查询做准备。

#Quick Start

git clone [email protected]:youyudehexie/redis-cache.git
npm install

#Example

var getCache = require('../lib').getCache;
var cache = require('../lib');

cache.init();  

getCache('aa', function(cb){
    cb(null, '123')

},function(err, data){
    console.log(data);
});

#Public API

##p.init()

初始化redis客户端,对模块进行简单配置

##p.getCache(key, func, cb)

首先,利用key查询缓存是否存在该值,若存在,则读取,若不存在,执行func,获取结果后存入到该键值的缓存下,并返回查询结果。

  • key: 从缓存里获取值的键值
  • func: 产生键值的函数
  • cb: 回调函数

#TODO

  • 支持更多的redisAPI和功能
