Vue 3: How to prevent reactivity implementing deeply nested objects in a props structure?
I've searched everywhere and can't find a clear answer. I tried several approaches but none seem to work. I'm working on a Vue 3 component that receives a deeply nested object as a prop. My goal is to ensure that changes to a property deep within this object correctly trigger reactivity without causing unnecessary re-renders of the entire component. I've set up the prop like this: ```javascript props: { userData: { type: Object, required: true } } ``` The question arises when I attempt to update a specific property within this nested structure. For example, if I have a user profile object like: ```javascript { name: 'John Doe', address: { street: '123 Main St', city: 'Anytown' } } ``` And I want to update the street name, I use a method like this: ```javascript methods: { updateStreet(newStreet) { this.userData.address.street = newStreet; } } ``` However, I'm working with a reactivity question where the view doesn't update as expected. When I check the console, I sometimes see warnings like "Avoid mutating a prop directly". I've tried using `this.$set()` and `Object.assign()` to create a new reference, but it seems to be inconsistent. Here's what I've done: ```javascript methods: { updateStreet(newStreet) { this.userData.address = { ...this.userData.address, street: newStreet }; // or use this.$set // this.$set(this.userData.address, 'street', newStreet); } } ``` But the updates still don't reflect in the UI. I also considered using a Vuex store for state management, but I'm unsure if that's necessary for this simple case. Is there a more effective pattern or technique in Vue 3 to handle updates to deeply nested reactive properties in props? Any insights would be greatly appreciated. For context: I'm using Javascript on macOS. I'd love to hear your thoughts on this.
