After thoroughly checking all similar questions on this platform, I did not find any relevant solutions. In most cases, the error seems to occur when utilizing
components:[comp1,comp2]
This is incorrect because the components property should be an object. However, in my scenario, the perplexing aspect is that this issue arises randomly. Sometimes simply reloading the page resolves the error temporarily. Strangely enough, it works perfectly multiple times and then the error resurfaces without any changes made to the code.
The project involves constructing a tree/hierarchy structure where each node can possess multiple children. Each node requires its own state - allowing for the opening of one node while closing others, as well as the ability to close all nodes from the grandparent component. The structure is outlined below:
MetadataTree - hierarchy container
<template>
<ul>
<li v-for="(value,key) in metadata">
<TreeItem :type="key" :members="value" :parent-open="parentOpen" :key="key"/>
</li>
</ul>
</template>
<script>
import TreeItem from '@/components/TreeItem.vue'
import TheButton from '@/components/TheButton.vue'
export default {
components:{TreeItem,TheButton},
props:['metadata','parentOpen'],
}
</script>
Each item employs a TreeItem component.
TreeItem - each node
<template>
<div>
<span class="icon-text">
<span v-if="isOpen" class="icon">
<i class="fas fa-folder-open"></i>
</span>
<span v-if="!isOpen" class="icon">
<i class="fas fa-folder"></i>
</span>
<span class="type" @click="toggle">{{type}}</span>
</span>
</div>
<li v-if="isOpen" v-for="member in members" :key="member.id">
<span class="icon-text">
<span class="icon">
<i class="fas fa-code"></i>
</span>
<span><a :href="member.url" target="_blank">{{member.name}}</a></span>
<Pill v-for="pill in member.pills" :pill="pill"/>
</span>
<p v-if="member.references">There are children
<MetadataTree :key="member.name" :metadata="member.references"/>
</p>
</li>
</template>
<script>
import MetadataTree from './MetadataTree.vue';
import Pill from '@/components/Pill.vue'
export default {
components:{Pill,MetadataTree},
props:['type','members','parentOpen'],
data(){
return{
isOpen:false
}
}
As observed, the TreeItem component references its parent component, MetadataTree, whenever the member variable contains a references variable.
Upon loading the page, only the initial 2 levels are shown, after which the console displays an error message for subsequent levels:
[Vue warn]: Failed to resolve component: MetadataTree
at <TreeItem type="CustomObject" members= (3) [{…}, {…}, {…}] parent-open=false ... >
This led me to believe that there might be an obstacle preventing the child component from being loaded within the parent component. It's important to note that there is a base case where member.references returns false, causing the tree to halt at that point.
Is it permissible for a child component to reference its parent under circumstances where a base case prevents infinite recursion? What other steps could I take to troubleshoot this recurring issue?
