Code working in Vue3 Playground but not in Inertia Environment

[philharmonie]

Version:

• @inertiajs/vue3 version: ^1.0.0

Describe the problem:

I have a very simple code that is working in a plain vue3 playground:

// App.vue
<script setup>
import { reactive } from 'vue'
import Child from './Child.vue'

const data = reactive({
  assets: [
    {
      id: 1,
      name: 'Foo'
    },
    {
      id: 2,
      name: 'Bar'
    },
  ]
})

const handleNewAsset = (newAssets) => {
  data.assets = newAssets
}
</script>

<template>
  <Child :assets="data.assets" @update:assets="handleNewAsset" />
</template>

// Child.vue
<script setup>
import {ref} from 'vue'

const {assets} = defineProps({
  assets: {
    type: Array
  }
})
const emit = defineEmits(['update:assets'])

const newName = ref('')

const add = () => {
  assets.push({
    id: assets.length + 1,
    name: newName.value
  })
}

const remove = (object) => emit('update:assets', assets.filter(asset => asset.id !== object.id))

</script>

<template>
  <h1>Assets</h1>
  <ul>
    <li v-for="asset in assets" :key="asset.id"><strong>id:</strong> {{asset.id}} <strong>name:</strong> {{asset.name}} <button @click="remove(asset)">x</button></li>
  </ul>
  <input v-model="newName" />
  <button @click="add">Add</button>
</template>

The exact same code is not working in an inertia environment. If you remove an assets from the list, in Inertia items are not removing.

Steps to reproduce:

• laravel new bug
• cd bug
• open resources/js/Pages/Welcome.vue
• replace the content of Welcome.vue with the code from App.vue
• adjust the import import Child from '@/Pages/Child.vue'
• create a new file resources/js/Pages/Child.vue
• paste the content of Child.vue to it

Now add items and remove items. In the playground the code is working as expected. In Inertia the behavior is not working

Since your code doesn't use any Inertia-specific features, it's highly likely a bug in your app's codebase. I've copied your component examples into the Vue Starter Kit, and they work as expected.
