1. Installation dependencies
npm install svg-sprite-loader
2. Configuration options Configure the following code in
the chainWebpack of vue.config.js Explanation: config.module.rule is a method used to obtain the rules of an object. .exclude.add (file a) is to add file a to the disabled group, that is, to disable file a. .test(/.svg$/) is a file matching the end of .svg
config.module
.rule('svg')
.exclude.add(resolve('src/icons')) //对应下面配置svg的路径
.end();
config.module
.rule('icons')
.test(/\.svg$/)
.include.add(resolve('src/icons')) //对应下面配置svg的路径
.end()
.use('svg-sprite-loader')
.loader('svg-sprite-loader')
.options({
symbolId: 'icon-[name]'
});
3. Define components
By encapsulating svg into components, we can call svg images in the form of components. Write components under components.
componnets/svgIcon/index.vue:
<template>
<svg :class="svgClass" aria-hidden="true" v-on="$listeners">
<use :xlink:href="iconName"/>
</svg>
</template>
<script>
export default {
name: 'SvgIcon',
props: {
iconClass: {
type: String,
required: true
},
className: {
type: String,
default: ''
}
},
computed: {
iconName() {
return `#icon-${
this.iconClass}`
},
svgClass() {
if (this.className) {
return 'svg-icon ' + this.className
} else {
return 'svg-icon'
}
}
}
}
</script>
<style scoped>
.svg-icon {
width: 10em;
height: 10em;
vertical-align: -0.15em;
fill: currentColor;
overflow: hidden;
}
</style>
4. Store images and register globally
Create a file directory and place svg images
I put svg images in the src/icons/svg folder, and then register svgIcon as a global component
src/icons/index.js:
import Vue from 'vue'
import SvgIcon from '@/components/svgIcon/index'// svg component
// register globally
Vue.component('svg-icon', SvgIcon)
const req = require.context('./svg', false, /\.svg$/)
const requireAll = requireContext => requireContext.keys().map(requireContext)
requireAll(req)
5. Global import
Import the registration file in mian.js
import './icons'
6. Use
For example, there is a picture rain.svg, the path is icons/svg/rain.svg, and then it can be called directly by the name. Here className is a custom style
//<svg-icon icon-class="图片名" className="样式类"></svg-icon>
<svg-icon icon-class="rain" className="iconBig"></svg-icon>
