$children

removed

Overview

The $children instance property has been removed from Vue 3.0 and is no longer supported.

2.x Syntax

In 2.x, developers could access direct child components of the current instance with this.$children:

<template>
  <div>
    <img alt="Vue logo" src="./assets/logo.png">
    <my-button>Change logo</my-button>
  </div>
</template>

<script>
import MyButton from './MyButton'

export default {
  components: {
    MyButton
  },
  mounted() {
    console.log(this.$children) // [VueComponent]
  }
}
</script>

3.x Update

In 3.x, the $children property is removed and no longer supported. Instead, if you need to access a child component instance, we recommend using $refs.
