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 🙏

NNCache

使用 node.js 实现的 key-value 缓存服务器,仿 Redis 的主要功能

包括服务端与客户端,能持久化到文件

主要接口:

  1. set
  2. get
  3. del
  4. sub
  5. unsub
  6. saveToFile
  7. getConnectStatus

server demo

const { createServer } = require("nncache");
createServer({
  port: 90, //监听端口
  autoSaveToFile: true, //是否持久化
  saveToFileInterval: 5000, //自动保存间隙
  debug: true, //输出调试信息
  subEnable: false, //是否开启订阅
  dbFilePath: "./db.json", //数据库文件
});

client demo

const { createClient } = require("nncache");

async function main() {
  let cache = createClient({
    url: "ws://localhost:90",
  });
  cache.set("cbf", 123);
  let d = await cache.get("cbf");
  console.log(d);
  setInterval(function () {
    cache.set("cbf2", new Date().valueOf());
  }, 1000);

  let i = 0;
  cache.sub("cbf2", function (json) {
    // i++;
    // if (i == 20) {
    //     cache.unsub('cbf2');
    //   return console.log("取消订阅");
    // }
    console.log("收到订阅:", json);
    // console.log(json);
  });
}

main();
