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 🙏

Readme

核心代码部分,分为服务端和客户端

Server 服务端

bootstrap.js 封装了http、tcp、udp

Client 客户端

client.js nodejs 版客户端,封装了http、tcp、udp

通信流程

http 走websocket,Many-Server-Many

tcp 走websocket,Many-Server-One-Many

udp 走websocket,Many-Server-One-Many

特殊

http 的headers中:

  • host=目标服务器的host
  • v-host=nat服务器host

作用是为了防止大部分服务器的nginx判断了host, 如果不是自己的域名,会造成无限301, 或者会跳转出nat域名,这样做是为了兼容。

http 传输 request和response都是流式操作,能达到100%兼容http

而且还减少了爆内存的几率,大文件双向传输最多只占用带宽,对CPU和内存没过多的占用。

部署

需要关闭服务器的防火墙,并且保证10000-65536的TCP端口没有被占用。这些区间的端口,将会根据数据库中已有端口进行随机分配。

# 安装
