刷新Vue.js组件的最佳方式是什么

<template>
  <MyComponent :key="componentKey" />
</template>

<script>
export default {
  data() {
    return {
      componentKey: 0
    };
  },
  methods: {
    refreshComponent() {
      this.componentKey += 1;
    }
  }
};
</script>

<template>
  <div v-if="showComponent">
    <MyComponent />
  </div>
</template>

<script>
export default {
  data() {
    return {
      showComponent: true
    };
  },
  methods: {
    refreshComponent() {
      this.showComponent = false;
      this.$nextTick(() => {
        this.showComponent = true;
      });
    }
  }
};
</script>

<template>
  <MyComponent :data="computedData" />
</template>

<script>
export default {
  data() {
    return {
      rawData: {}
    };
  },
  computed: {
    computedData() {
      // 根据rawData计算新的数据
      return processData(this.rawData);
    }
  },
  watch: {
    rawData: {
      handler() {
        // 当rawData变化时，执行需要的操作
      },
      deep: true
    }
  }
};
</script>

methods: {
  refreshComponent() {
    this.$forceUpdate();
  }
}
