Handling deeply nested arrays in Vue.js with dynamic data
I'm maintaining legacy code that Quick question that's been bugging me - Building a Vue.js application where I need to handle deeply nested arrays... My data structure can look something like this: ```javascript const data = [ { id: 1, name: 'Item 1', children: [ { id: 2, name: 'Sub Item 1', children: [] }, { id: 3, name: 'Sub Item 2', children: [] } ] }, { id: 4, name: 'Item 2', children: [ { id: 5, name: 'Sub Item 3', children: [] } ] } ]; ``` My goal is to render this data in a tree structure, allowing users to expand or collapse the child elements. I've tried using a recursive component approach, but the state management for dynamically adding or removing items is getting complicated. Here’s a simplified version of what I have: ```html <template> <div> <tree-item v-for="item in items" :key="item.id" :item="item" @addChild="addChild" /> </div> </template> ``` And the `tree-item` component looks like this: ```html <template> <div> <span @click="isOpen = !isOpen">{{ item.name }}</span> <div v-if="isOpen"> <tree-item v-for="child in item.children" :key="child.id" :item="child" /> <button @click="addChild">Add Child</button> </div> </div> </template> <script> export default { props: ['item'], data() { return { isOpen: false }; }, methods: { addChild() { // logic to add a child } } } </script> ``` Inside the `addChild` method, I want to ensure that when a user clicks the button, it dynamically updates both the structure and the UI without losing the current state. I’ve attempted to use Vue’s reactivity features, such as `Vue.set`, but occasionally it fails to trigger updates correctly. In addition, I’m concerned about performance as the item count grows large. Should I consider virtual scrolling or another rendering strategy to manage performance? Any insights on best practices for handling deeply nested structures in Vue would be greatly appreciated. This is happening in both development and production on macOS. Thanks, I really appreciate it! This is part of a larger desktop app I'm building. How would you solve this?
