SvgIcon.vue

</template>

<script>

export default {

<style scoped>
.svg-icon {
  width: 1em;
  height: 1em;
  vertical-align: -0.15em;

  overflow: hidden;
}
</style>

svg-icon/index.js

import SvgIcon from './SvgIcon.vue'
export default (Vue) => {
  // 全局注册
  Vue.component('svg-icon', SvgIcon);
  // 导入所有svg文件
  const requireAll = requireContext => requireContext.keys().map(requireContext);
  const req = require.context('@/assets/svg', false, /\.svg$/);
  requireAll(req);
}

index

import SvgIcon from "./svg-icon";
export default (Vue) => {
  Vue.use(SvgIcon);
}

main.js

// 增加
import PublicComponent from '@/components'
Vue.use(PublicComponent);

使用组件

<svg-icon icon-class="add" class="svg-color"/>

<style scoped>
.svg-color {
  color: red;
}
</style>
