vue中使用svg图标

1 npm安装

npm install svg-sprite-loader --save-dev

2svg 组件 src/components/SvgIcon/index.vue

  <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>
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: 1em;
  height: 1em;
  vertical-align: -0.15em;
  fill: currentColor;
  overflow: hidden;
}

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

3@/utils/validate.js

export function isExternal(path) {
  return /^(https?:|mailto:|tel:)/.test(path)
}

4全局注册src/icons/index.js

import Vue from 'vue'
import SvgIcon from '@/components/SvgIcon'


Vue.component('svg-icon', SvgIcon)

const req = require.context('./svg', false, /\.svg$/)
const requireAll = requireContext => requireContext.keys().map(requireContext)

requireAll(req)

5 main.js 引入 import './icons'

6vue.config.js中配置

const path = require("path");
const resolve = str => path.join(__dirname, str);
 
module.exports = {
    chainWebpack: (config) => {  
			
		config.module
			.rule('svg')
			.exclude.add(resolve('src/icons'))
			.end()
		config.module
			.rule('icons')
			.test(/\.svg$/)
			.include.add(resolve('src/icons'))
			.end()
			.use('svg-sprite-loader')
			.loader('svg-sprite-loader')
			.options({
				symbolId: 'icon-[name]'
			})
			.end()
  }
}

7使用 <svg-icon icon-class="文件名"/>不加svg后缀
