vite-plugin-svg-icons

English | 中文

Used to generate svg sprite map.

Feature

• Preloading All icons are generated when the project is running, and you only need to operate dom once.
• High performance Built-in cache, it will be regenerated only when the file is modified.

Installation (yarn or npm)

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

Usage

• Configuration plugin in vite.config.ts

import { createSvgIconsPlugin } from 'vite-plugin-svg-icons'
import path from 'path'

export default () => {
  return {
    plugins: [
      createSvgIconsPlugin({
        // Specify the icon folder to be cached
        iconDirs: [path.resolve(process.cwd(), 'src/icons')],
        // Specify symbolId format
        symbolId: 'icon-[dir]-[name]',

        /**
         * custom insert position
         * @default: body-last
         */
        inject?: 'body-last' | 'body-first'

        /**
         * custom dom id
         * @default: __svg__icons__dom__
         */
        customDomId: '__svg__icons__dom__',
      }),
    ],
  }
}

• Introduce the registration script in src/main.ts

import 'virtual:svg-icons-register'

Here the svg sprite map has been generated

How to use in components

Vue way

/src/components/SvgIcon.vue

<template>
  <svg aria-hidden="true">
    <use :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 Directory Structure

# 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 way

/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>
  )
}

Icons Directory Structure

# src/icons

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

/src/App.jsx

import SvgIcon from './components/SvgIcon'

export default function App() {
  return (
    <>
      <SvgIcon name="icon1"></SvgIcon>
      <SvgIcon name="icon1"></SvgIcon>
      <SvgIcon name="icon1"></SvgIcon>
      <SvgIcon name="dir-icon1"></SvgIcon>
    </>
  )
}

Get all SymbolId

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

Options

| Parameter | Type | Default | Description | | ----------- | ---------------------- | --------------------- | ------------------------------------------------------------------------------------- | | iconDirs | string[] | - | Need to generate the icon folder of the Sprite image | | symbolId | string | icon-[dir]-[name] | svg symbolId format, see the description below | | svgoOptions | boolean｜SvgoOptions | true | svg compression configuration, can be an objectOptions | | inject | string | body-last | svgDom default insertion position, optional body-first | | customDomId | string | __svg__icons__dom__ | Customize the ID of the svgDom insert node |

symbolId

icon-[dir]-[name]

[name]:

svg file name

[dir]

The svg of the plug-in will not generate hash to distinguish, but distinguish it by folder.

If the folder corresponding to iconDirs contains this other folder

example:

Then the generated SymbolId is written in the comment

# 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 Support

If using Typescript, you can add in tsconfig.json

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

Note

Although the use of folders to distinguish between them can largely avoid the problem of duplicate names, there will also be svgs with multiple folders and the same file name in iconDirs.

This needs to be avoided by the developer himself

Example

Run

pnpm install
pnpm run dev
pnpm run build
