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 🙏

Sticky-iphash

Sticky-iphash 模块为 Node.js 增加 ip-hash 负载均衡策略:拥有相同远端地址(IPv4/v6)的连接会被分发到相同的进程。

开发者只需在 Master 进程引入此模块并启用,无需修改原有业务逻辑与代码与 Node.js 源码,即可为 Node.js cluster 开启此均衡策略。

模块对上层完全透明,开启后直接使用 Node.js cluster 启动多进程,支持 cluster 模块所有提供的特性。

使用此模块时,Node.js 在启动时需开启 --expose_internals 标志位。

Node.js 版本需大于 v7.5.x

安装

npm i sticky-iphash

用法

const sticky = require('sticky-iphash');
sticky.enable();

例子

const cluster = require('cluster');

if (cluster.isMaster) {
  // Master 进程中开启 `sticky-iphash`
  const sticky = require('sticky-iphash');
  sticky.enable();

  console.log(`Master ${process.pid} is running`);

  const numCPUs = require('os').cpus().length;
  for (let i = 0; i < numCPUs; i++) {
    cluster.fork();
  }

  cluster.on('exit', (worker) => {
    console.log(`worker ${worker.process.pid} died`);
  });
} else {
  const http = require('http');

  const requestListener = (req, res) => {
    res.writeHead(200);
    const { socket : { remoteAddress, localPort } } = req;
    res.end(`remoteAddress = ${remoteAddress}, localPort = ${localPort}, pid = ${process.pid}`);
  };

  http.createServer(requestListener).listen(8000);
  http.createServer(requestListener).listen(8001);

  console.log(`Worker ${process.pid} started`);
}

使用 --expose_internals 标志位启动 Node.js

node --expose_internals server.js
