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 🙏

fe-selector

v0.1.0

Published

A framework-agnostic element selector SDK that auto-detects your framework (React 18/19, Vue 3, vanilla JS).

Readme

fe-selector

框架无关的前端元素选择 SDK。按住修饰键悬停任意 DOM 元素,自动提取组件名、props、样式、源码位置,通过回调或 postMessage 传递给 AI 聊天面板。

支持 React 18/19Vue 3 及原生 JS,自动检测框架,无需手动配置。

功能

  • 元素高亮选择:按住 Alt(或自定义修饰键)悬停元素即可高亮,点击选中
  • 深度上下文提取:自动提取组件名、props、CSS 样式、DOM 路径、源码文件 & 行号
  • 框架自动检测:无缝支持 React 18/19 Fiber、Vue 3 devtools 及原生 DOM
  • Shadow DOM 覆盖层:高亮层通过 Shadow DOM 隔离,不污染用户页面样式
  • postMessage 通信:与 opt-ui Shell 集成时,通过标准握手协议传递元素上下文
  • 手动模式 API:支持通过 activate() / deactivate() 以编程方式控制选择模式
  • Tree-shakable:提供 ./core(纯 JS)、./react(React 专属)多个导出路径,按需引入

安装

npm install fe-selector
# 或
pnpm add fe-selector

快速上手

import { init } from 'fe-selector'

// 仅在开发环境启用
if (import.meta.env.DEV) {
  init({ activationKey: 'alt' })
}

按住 Alt 键悬停元素 → 高亮 → 点击选中 → 触发 onSelect 回调或向 opt-ui Shell 发送 postMessage。

与 opt-ui Shell 配合使用

opt-ui Shell 将你的项目运行在 iframe 沙箱内,AI 聊天面板独立存活、不受 iframe 崩溃影响。配置 SDK 后选中元素,元素上下文自动填入聊天输入框。
