Vue3 and Ionic combined to create a Component that became a reactive object in Vue

Vue is issuing a warning about receiving a Component as a reactive object, which can cause unnecessary performance overhead. The warning suggests using markRaw or shallowRef instead of ref to avoid this issue. However, in my code, I am not explicitly using ref, shallowRef, or markRaw.

Here is the code snippet:

<template>
    <ion-page>
        <ion-nav :root="MorePageContainer"></ion-nav>
    </ion-page>
</template>

<script lang="ts">
import { IonNav, IonPage } from '@ionic/vue';
import MorePageComponent from "@/components/MorePageComponent.vue";

export default {
    components: {
        IonNav, IonPage
    },

    data() {
        return {
            MorePageComponent
        }
    }
}
</script>

Why am I receiving this warning if I am not using ref?

Answer №1

Here is a simple solution: transfer the component from data to setup in the following manner:

<template>
    <ion-page>
        <ion-nav :root="MorePageContainer"></ion-nav>
    </ion-page>
</template>

<script lang="ts">
import { IonNav, IonPage } from '@ionic/vue';
import MorePageComponentfrom "@/components/MorePageComponent.vue";

export default {
    components: {
        IonNav, IonPage
    },

    setup() {
        return {
            MorePageComponent
        }
    }
}
</script>
