[Vue.js 3.0] Migration – $children

# $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.
