图⽂详解如何在vue3+vite项⽬中使⽤svg
今天在vue3+vite项⽬练习中，在使⽤svg时，发现之前的写法不能⽤，之前的使⽤⽅法参考vue2中优雅的使⽤svg const req = t('./icons/svg', false, /\.svg$/)
const requireAll = requireContent => requireContent.keys().map(requireContent)
requireAll(req)
然后就各种资料查，终于实现了，废话不多说，直接上代码：
stept1: ⽂件⽬录
stept2: 安装 svg-sprite-loader
npm install svg-sprite-loader -D
svg交互图文入门# via yarn
yarn add svg-sprite-loader -D
stept3: 创建svgIcon.vue⽂件
<template>
<svg :class="svgClass" v-bind="$attrs" :>
<use :xlink:href="iconName" rel="external nofollow" />
</svg>
</template>
<script setup>
import { defineProps, computed } from "vue";
const props = defineProps({
name: {
type: String,
required: true
},
color: {
type: String,
default: ''
}
})
const iconName = computed(()=>`#icon-${props.name}`);
const svgClass = computed(()=> {
console.log(props.name, 'props.name');
if (props.name) {
return `svg-icon icon-${props.name}`
}
return 'svg-icon'
});
</script>
<style lang='scss'>
.svg-icon {
width: 1em;
height: 1em;
fill: currentColor;
vertical-align: middle;
}
</style>
stept4: 创建icons⽂件夹，存放svg⽂件
stept5: 在main.js⾥⾯全局注⼊svg-icon组件
import { createApp } from 'vue'
import App from './App.vue'
import svgIcon from './components/svgIcon.vue'
createApp(App)ponent('svg-icon', svgIcon).mount('#app');
import { readFileSync, readdirSync } from 'fs'
let idPerfix = ''
const svgTitle = /<svg([^>+].*?)>/
const clearHeightWidth = /(width|height)="([^>+].*?)"/g
const hasViewBox = /(viewBox="[^>+].*?")/g
const clearReturn = /(\r)|(\n)/g
function findSvgFile(dir) {
const svgRes = []
const dirents = readdirSync(dir, {
withFileTypes: true
})
for (const dirent of dirents) {
if (dirent.isDirectory()) {
svgRes.push(...findSvgFile(dir + dirent.name + '/'))
} else {
const svg = readFileSync(dir + dirent.name)
.toString()
.replace(clearReturn, '')
.replace(svgTitle, ($1, $2) => {
// console.log(++i)
// console.log(dirent.name)
let width = 0
let height = 0
let content = $2.replace(
clearHeightWidth,
(s1, s2, s3) => {
if (s2 === 'width') {
width = s3
} else if (s2 === 'height') {
height = s3
}
return ''
}
)
if (!st($2)) {
content += `viewBox="0 0 ${width} ${height}"`
}
return `<symbol id="${idPerfix}-${place(
'.svg',
''
)}" ${content}>`
})
.replace('</svg>', '</symbol>')
svgRes.push(svg)
}
}
return svgRes
}
export const svgBuilder = (path, perfix = 'icon') => {
if (path === '') return
idPerfix = perfix
const res = findSvgFile(path)
// console.log(res.length)
// const res = []
return {
name: 'svg-transform',
transformIndexHtml(html) {
place(
'<body>',
`
<body>
<svg xmlns="/2000/svg" xmlns:xlink="/1999/xlink" >              ${res.join('')}
</svg>
`
)
}
}
}
stept7: 最后在fig.js修改配置
import { svgBuilder } from './src/plugins/svgBuilder';
export default defineConfig({
plugins: [svgBuilder('./src/icons/svg/')] // 这⾥已经将src/icons/svg/下的svg全部导⼊，⽆需再单独导⼊
})
