Vue-svg图标存放和取方案

[PleaseStartYourPerformance]

方案1

引入iconfont库，远程维护，本地更新

方案2

1.写个index.js

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

const re = /\.\/(.*)\.svg/

const icons = requireAll(req).map(i => {
  return i.match(re)[1]
})

export default icons

使用：
import icons from './requireIcons'
iconList: icons

     <div v-for="(item, index) in iconList" class="icon-item-wrapper" :key="index" @click="selectedIcon(item)">
          <div :class="['icon-item', { active: activeIcon === item }]">
            <svg-icon :icon-class="item" class-name="icon" style="height: 25px;width: 16px;"/>
            <span>{{ item }}</span>
          </div>
        </div>

注册svg-icon 在main.js引入

import './assets/icons' // icon

./assets/icons/index.js

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

<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>
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>
