vite-plugin-svg-icons

Used to generate svg sprite map.

"This is a fork of vite-plugin-svg-icon because the original package is no longer well-maintained. This repository fixes some minor bugs to ensure the package can continue to be used."

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 or pnpm)

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

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__',

        /**
         * option to perform a replacement of stroke colors with currentColor
         * @default：true
         */
        replaceStrokeWithCurrentColor: true        
      }),
    ],
  }
}

• 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
replaceStrokeWithCurrentColor	boolean	true	Whether to perform a replacement of stroke colors with currentColor

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