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 🙏

@supernathaniel/viewer

性能观测台：perfmgmt trace 数据的查询面板。交付物是 vite 构建产物 dist——由宿主静态托管、iframe 同源嵌入（与宿主 React 版本、CSS 完全隔离）。

功能

  • trace 列表：appKey / rootType（navigation / interaction / custom）/ route 过滤 + 分页；
  • trace 详情：事件时间轴（perfTrace/findById）；
  • 接口 baseURL 固定同源 /integration，路径带 .api 后缀（网关只对 .api 调用做前缀路由，并剥掉前缀与后缀）；
  • 鉴权失败（401/state:error）给引导态，不自动跳登录。

开发

# 起 dev server（5180），FP_API 指定 /integration 的代理入口（宿主 dev 或本机 perfmgmt）
FP_API=http://localhost:9092 pnpm --filter @supernathaniel/viewer dev

在宿主页面里做 HMR 调试（无需 link）：控制台执行 localStorage.setItem('FP_VIEWER_URL', 'http://localhost:5180') 后刷新。

部署

把 node_modules/@supernathaniel/viewer/dist 拷入宿主构建产物的同名子路径 （如 dist/fp-viewer/），由宿主既有静态托管（nginx/OSS/CDN）承接； dev 下由 @supernathaniel/umi-plugin 的 /fp-viewer/ 中间件同源托管同一 dist。
