<template>
  <div>
    <ChildComponent :value="parentValue" />
  </div>
</template>

<script>
import ChildComponent from './ChildComponent.vue';

export default {
  components: {
    ChildComponent
  },
  data() {
    return {
      parentValue: 'Hello from parent component'
    };
  }
};
</script>

<template>
  <div>
    <p>{{ value }}</p>
  </div>
</template>
