<template>
  <svg aria-hidden="true" class="svg-icon">
    <use :xlink:href="symbolId" rel="external nofollow"  :fill="color" />
  </svg>
</template>

<script setup lang="ts">
import { computed } from 'vue';

const props = defineProps({
  prefix: {type: String,default: 'icon',},
  iconClass: {type: String,required: true,},
  color: {type: String,default: ''}

const symbolId = computed(() => `#${props.prefix}-${props.iconClass}`);
