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 🙏

unplugin-offline-iconify

v1.0.0

Published

iconify 本地化插件,按需加载,生产环境无需请求远程 icon

Readme

unplugin-iconfiy

iconify 本地化插件,按需加载,生产环境无需请求远程 icon

实现

参考 vite-plugin-svg-icons-ng,不过 vite-plugin-svg-icons-ng 是将本地文件 svg 通过到页面,然后通过 use 引入,unplugin-iconify 通过识别项目中使用到的 iconify icon,将用到的 icon 提取出来注入页面,通过 use 引入

使用

npm i unplugin-offline-iconify -D

配置项

| 参数 | 类型 | 默认值 | 说明 | |------|------|--------|------| | cwd | string | 'src' | 扫描的根目录 | | include | string \| string[] | '**/*.{js,jsx,ts,tsx,vue,json,astro}' | 扫描的文件匹配模式 | | exclude | string \| string[] | [] | 额外排除的文件匹配模式(node_modules 已默认排除) |

Vite

目前仅测试了 Vite,并实现了 Vite 的 HMR 热更新支持。其他构建工具(Webpack、Rollup 等)理论上可用,但未经测试。

以 vite + react 为例

vite.config.js

import { defineConfig } from 'vite'
import react from '@vitejs/plugin-react'
import Icon from 'unplugin-offline-iconify/vite'

export default defineConfig({
  plugins: [
    react(),
    // 使用默认配置
    Icon(),
    // 或者自定义配置
    // Icon({
    //   cwd: 'src',
    //   include: '**/*.{js,jsx,ts,tsx,vue,json}',
    //   exclude: ['**/test/**'],
    // }),
  ],
})

main.jsx

import { StrictMode } from 'react'
import { createRoot } from 'react-dom/client'
import './index.css'
import App from './App.jsx'
import 'virtual:offline-iconify'

createRoot(document.getElementById('root')).render(
  <StrictMode>
    <App />
  </StrictMode>,
)

Icon 组件封装

以 React 为例封装 Icon 组件,其余框架也类似:

export default function Icon(props) {
  return (
    <svg style={{
      fontSize: props.size || '16px',
      color: props.fill,
      width: '1em',
      height: '1em',
    }}>
      <use xlinkHref={'#' + props.name} />
    </svg>
  )
}

在其他组件里引用:

import Icon from './component/Icon.jsx'

function App() {
  return (
    <div>
      <Icon name="ant-design:account-book-twotone" size="40px" fill="red" />
    </div>
  )
}
