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 🙏

轻量级、框架无关的 Web Components 组件库

Readme

@eosjs/ui

🎨 轻量级 Web Components 组件库

npm version npm downloads license

基于原生 Web Components 技术构建的轻量级组件库,支持在任何框架中使用。

✨ 特性

  • 🚀 框架无关 - 可在 React、Vue、Angular、原生 HTML 等任何环境中使用
  • 📦 轻量小巧 - 零框架依赖,打包体积小
  • 🎯 开箱即用 - 简单导入即可使用
  • 🌈 TypeScript 支持 - 基于 Custom Elements Manifest 自动生成类型声明,覆盖 React、Vue、Solid、Preact 等主流框架

📦 安装

pnpm add @eosjs/ui

🚀 快速开始

原生 HTML

<script type="module">
  import { registerComponents } from "@eosjs/ui";
  registerComponents();
</script>

<eos-button>点击我</eos-button>
<eos-image src="photo.jpg" placeholder="LKO2?U%2Tw=w]~RBVZRi" placeholder-type="blurhash" />

React

import { registerComponents } from "@eosjs/ui";
registerComponents();

function App() {
  return (
    <eos-carousel autoplay loop interval="3000" indicator-style="tiktok">
      <eos-image src="1.jpg" placeholder="LEHV6nWB2y..." placeholder-type="blurhash" />
      <eos-image src="2.jpg" placeholder="LGF5]+Yk^6..." placeholder-type="blurhash" />
    </eos-carousel>
  );
}

Vue

<script setup>
import { registerComponents } from "@eosjs/ui";
registerComponents();
</script>

<template>
  <eos-carousel autoplay loop interval="3000">
    <eos-image src="1.jpg" placeholder="LEHV6nWB2y..." placeholder-type="blurhash" />
  </eos-carousel>
</template>

🔤 TypeScript 类型支持

组件库通过 Custom Elements Manifest 自动生成类型声明,支持所有主流框架的 JSX/模板类型检查。

React / Preact

在 tsconfig.json 的 include 中添加类型文件:

{
  "include": ["src", "node_modules/@eosjs/ui/jsx-types.d.ts"]
}

注意:React 会将 onChange 映射为原生 change 事件,导致 e.detail 丢失。监听 Web Components 的自定义事件请使用 ref + addEventListener:

const ref = useRef<HTMLElement>(null);
useEffect(() => {
  const el = ref.current;
  const handler = (e: Event) => {
    const { currentIndex } = (e as CustomEvent).detail;
  };
  el?.addEventListener("change", handler);
  return () => el?.removeEventListener("change", handler);
}, []);

Vue

Vue 通过 HTMLElementTagNameMap 自动获得类型支持,无需额外配置。在 vite.config.ts 中将 eos- 前缀标记为自定义元素:

vue({
  template: {
    compilerOptions: {
      isCustomElement: (tag) => tag.startsWith("eos-"),
    },
  },
})

Angular

Angular 在模块中添加 CUSTOM_ELEMENTS_SCHEMA:

import { CUSTOM_ELEMENTS_SCHEMA } from "@angular/core";

@Component({
  schemas: [CUSTOM_ELEMENTS_SCHEMA],
})
