在VUE项目中使用svg图标

安装项目依赖

npm i svg-sprite-loader@4.1.3

这里之后打包的时候，可能会报非常多错误，比如：Error Cannot find module ‘webpacklibRuleSet‘
若有报这个错误，重新安装一下webpack

npm i webpack@4.29.5 --force

在src目录下新建文件夹

index.vue:

<template>
  <div v-if="isExternal" :style="styleExternalIcon" class="svg-external-icon svg-icon" v-on="$listeners" />
  <svg v-else :class="svgClass" aria-hidden="true" v-on="$listeners">
      <use :xlink:href="iconName" />
  </svg>
</template>

<script>
// doc: https://panjiachen.github.io/vue-element-admin-site/feature/component/svg-icon.html#usage
import { isExternal } from '../../utils/validate'

export default {
  name: 'SvgIcon',
  props: {
      iconClass: {
          type: String,
          required: true
      },
      className: {
          type: String,
          default: ''
      }
  },
  computed: {
      isExternal() {
          return isExternal(this.iconClass)
      },
      iconName() {
          return `#icon-${this.iconClass}`
      },
      svgClass() {
          if (this.className) {
              return 'svg-icon ' + this.className
          } else {
              return 'svg-icon'
          }
      },
      styleExternalIcon() {
          return {
              mask: `url(${this.iconClass}) no-repeat 50% 50%`,
              '-webkit-mask': `url(${this.iconClass}) no-repeat 50% 50%`
          }
      }
  }
}
</script>

<style scoped>
.svg-icon {
  width: 1.2em;
  height: 1.2em;
  /* vertical-align: -0.15em; */
  fill: currentColor;
  overflow: hidden;
}

.svg-external-icon {
  background-color: currentColor;
  mask-size: cover !important;
  display: inline-block;
}
</style>

在src目录下新建文件夹

index.js:

import Vue from 'vue'
import SvgIcon from '@/components/SvgIcon'// svg component
 
// register globally
Vue.component('SvgIcon', SvgIcon)
 
const req = require.context('./svg', false, /\.svg$/)
const requireAll = requireContext => requireContext.keys().map(requireContext)
requireAll(req)

在svg中放我们需要引用的svg图片

在main中引用：

Vue.config.productionTip = false
import '@/icons'

配置 vue.config.js

const { defineConfig } = require('@vue/cli-service')
const path = require("path");
function resolve(dir) {
  return path.join(__dirname, dir);
}

module.exports = defineConfig({
  transpileDependencies: true,
   chainWebpack (config) {
    // set svg-sprite-loader
    config.module
      .rule('svg')
      .exclude.add(resolve('src/icons'))
      .end()
    config.module
      .rule('icons')
      .test(/\.svg$/) //不要压缩，会出不来
      .include.add(resolve('src/icons'))
      .end()
      .use('svg-sprite-loader')
      .loader('svg-sprite-loader')
      .options({
        symbolId: 'icon-[name]'
      })
      .end()
  }
})

使用

<SvgIcon
                icon-class="limit"
                class="item_icon"
              ></SvgIcon>

去掉可以改svg颜色
