Vue 3 - Watcher Not Reacting to Nested Object Changes in Reactive State
I've tried everything I can think of but I'm getting frustrated with I'm working on a project and hit a roadblock. I'm using Vue 3's Composition API and I've run into an scenario where my watcher isn't triggering when I modify a nested property of a reactive object. Here's a simplified version of my setup: ```javascript import { ref, watch } from 'vue'; export default { setup() { const state = ref({ user: { name: 'Alice', age: 30 } }); watch(() => state.value.user, (newUser, oldUser) => { console.log('User changed:', newUser); }, { deep: true }); // Simulate an update to the nested property const updateUserName = () => { state.value.user.name = 'Bob'; }; return { state, updateUserName }; } }; ``` I expected the watcher to log the message when I call `updateUserName`, but it seems like the watcher isn't detecting changes to the `name` property. I've verified that the `deep` option is set to true, so I'm not sure why this isn't working. I've tried adding a console log inside the watcher to see if it's being called at all, and it isn't. I've also checked if the reactive state is being updated correctly, and it is. Is there something I'm missing with how Vue handles reactivity for nested objects? Any insights would be greatly appreciated! Is there a better approach? I recently upgraded to Javascript latest. Any examples would be super helpful. I'm using Javascript 3.9 in this project.
