Vue 3: How to dynamically update a nested object's property in a reactive array without losing reactivity?
Hey everyone, I'm running into an issue that's driving me crazy. I'm deploying to production and I'm stuck on something that should probably be simple. I've been banging my head against this for hours. I'm working with a Vue 3 application where I have an array of objects, and each object contains another nested object. I need to update a property of the nested object based on user input, but I'm running into issues with reactivity. Here's a simplified version of my code: ```javascript const { reactive, toRefs } = require('vue'); const state = reactive({ items: [ { id: 1, details: { name: 'Item 1', quantity: 10 } }, { id: 2, details: { name: 'Item 2', quantity: 5 } }, ] }); const updateQuantity = (id, newQuantity) => { const item = state.items.find(item => item.id === id); if (item) { // Trying to update nested property item.details.quantity = newQuantity; } }; ``` When I call `updateQuantity(1, 20)`, the quantity updates in the object, but the UI doesn't reflect this change. I’ve confirmed that `state.items` is reactive, but it seems like Vue 3 isn’t tracking the updates to the nested `details` object. I've tried using `Vue.set()` and wrapping the nested object with `reactive()`, but neither approach has resolved the scenario. Also, I'm not seeing any behavior messages in the console, which makes it harder to debug. I would appreciate any insights on how to properly trigger reactivity when working with nested objects in this scenario. Am I missing something essential in my implementation? I'd really appreciate any guidance on this. My development environment is Linux. I'm developing on Windows 11 with Javascript. Any help would be greatly appreciated! What's the correct way to implement this?
