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 🙏

vite-plugin-svg-icons

中文 | English

用于生成 svg 雪碧图.

特征

  • 预加载 在项目运行时就生成所有图标,只需操作一次 dom
  • 高性能 内置缓存,仅当文件被修改时才会重新生成

安装

node version: >=12.0.0

vite version: >=2.0.0

yarn add vite-plugin-svg-icons -D
# or
npm i vite-plugin-svg-icons -D
# or
pnpm install vite-plugin-svg-icons -D

使用

  • vite.config.ts 中的配置插件
import { createSvgIconsPlugin } from 'vite-plugin-svg-icons'
import path from 'path'

export default () => {
  return {
    plugins: [
      createSvgIconsPlugin({
        // 指定需要缓存的图标文件夹
        iconDirs: [path.resolve(process.cwd(), 'src/icons')],
        // 指定symbolId格式
        symbolId: 'icon-[dir]-[name]',

        /**
         * 自定义插入位置
         * @default: body-last
         */
        inject?: 'body-last' | 'body-first'

        /**
         * custom dom id
         * @default: __svg__icons__dom__
         */
        customDomId: '__svg__icons__dom__',
      }),
    ],
  }
}
  • 在 src/main.ts 内引入注册脚本
import 'virtual:svg-icons-register'

到这里 svg 雪碧图已经生成

如何在组件使用

Vue 方式

/src/components/SvgIcon.vue

<template>
  <svg aria-hidden="true">
    <use :xlink:href="symbolId" :fill="color" />
  </svg>
</template>

<script>
import { defineComponent, computed } from 'vue'

export default defineComponent({
  name: 'SvgIcon',
  props: {
    prefix: {
      type: String,
      default: 'icon',
    },
    name: {
      type: String,
      required: true,
    },
    color: {
      type: String,
      default: '#333',
    },
  },
  setup(props) {
    const symbolId = computed(() => `#${props.prefix}-${props.name}`)
    return { symbolId }
  },
})
</script>

icons 目录结构

# src/icons

- icon1.svg
- icon2.svg
- icon3.svg
- dir/icon1.svg

/src/App.vue

<template>
  <div>
    <SvgIcon name="icon1"></SvgIcon>
    <SvgIcon name="icon2"></SvgIcon>
    <SvgIcon name="icon3"></SvgIcon>
    <SvgIcon name="dir-icon1"></SvgIcon>
  </div>
</template>

<script>
import { defineComponent, computed } from 'vue'

import SvgIcon from './components/SvgIcon.vue'
export default defineComponent({
  name: 'App',
  components: { SvgIcon },
})
</script>

React 方式

/src/components/SvgIcon.jsx

export default function SvgIcon({
  name,
  prefix = 'icon',
  color = '#333',
  ...props
}) {
  const symbolId = `#${prefix}-${name}`

  return (
    <svg {...props} aria-hidden="true">
      <use href={symbolId} fill={color} />
    </svg>
  )
}

获取所有 SymbolId

import ids from 'virtual:svg-icons-names'
// => ['icon-icon1','icon-icon2','icon-icon3']

配置说明

| 参数 | 类型 | 默认值 | 说明 | | ----------- | ---------------------- | --------------------- | -------------------------------------------------------------- | | iconDirs | string[] | - | 需要生成雪碧图的图标文件夹 | | symbolId | string | icon-[dir]-[name] | svg 的 symbolId 格式,见下方说明 | | svgoOptions | boolean|SvgoOptions | true | svg 压缩配置,可以是对象Options | | inject | string | body-last | svgDom 默认插入的位置,可选body-first | | customDomId | string | __svg__icons__dom__ | svgDom 插入节点的 ID |

symbolId

icon-[dir]-[name]

[name]:

svg 文件名

[dir]

该插件的 svg 不会生成 hash 来区分,而是通过文件夹来区分.

如果iconDirs对应的文件夹下面包含这其他文件夹

例:

则生成的 SymbolId 为注释所写

# src/icons
- icon1.svg # icon-icon1
- icon2.svg # icon-icon2
- icon3.svg # icon-icon3
- dir/icon1.svg # icon-dir-icon1
- dir/dir2/icon1.svg # icon-dir-dir2-icon1

Typescript 支持

如果使用 Typescript,你可以在tsconfig.json内添加

// tsconfig.json
{
  "compilerOptions": {
    "types": ["vite-plugin-svg-icons/client"]
  }
}

注意

虽然用文件夹来区分已经可以很大程度避免重名问题了,但是也会出现iconDirs包含多个文件夹,且文件名一样的 svg.

这个需要开发者自己规避下

示例

运行示例


pnpm install
cd ./packages/playground/basic
pnpm run dev
pnpm run build
