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 🙏

通讯流程设计

文档:房间 -> 1:1

  1. step1、step2 同步数据
  2. message
  3. awareness

文档:房间 -> n:1

思路一:消息中增加标识位

  1. step1、step2 同步数据
  2. message
  3. awareness

同样是上面的三种同步,只不过每次同步数据时都把 guid 带上,标识数据同步的是哪个文档的,以前房间就代表文档,所以不需要传

这样的设计意味着每一次 ws 链接(第一次连以及后续的断开重连),每一个文档都需要和服务器进行一次 step1 和 step2 的握手,预测消息密度会非常的大

实践中发现的一个问题是:新建 record 的操作需要走两次同步才可以完成数据传递,一次是新建动作,一次是新建对应的初始化数据

思路二:单条消息支持多个文档的 update

这种方式就是在思路一的基础上进行的扩展的,就是想实现一条同步消息中可以包含多个文档的更新:type-guid0-update-guid1-update...

这种方式理论上可行,并且可以解决思路一种的消息过密以及一个动作多次同步的问题
