Vue 3: Handling Route Changes with Watchers and Keeping State in Child Components
I recently switched to I'm trying to debug I'm working on a Vue 3 application where I need to maintain the state of a child component when the parent route changes... I'm using Vue Router and want to keep the data in my child component intact so that users don't lose their input. I've set up a watcher on the route, but it seems that the child component is being destroyed and recreated every time I navigate to a different route, which resets its state. Here's a simplified version of my setup: ```javascript // ParentComponent.vue <template> <router-view></router-view> </template> <script> import { watch } from 'vue'; export default { setup() { // Watch for route changes watch(() => $route, (to, from) => { console.log(`Navigating from ${from.path} to ${to.path}`); // Attempting to retain some state }); } }; </script> ``` And my child component looks like this: ```javascript // ChildComponent.vue <template> <input v-model="inputValue" /> </template> <script> import { ref } from 'vue'; export default { setup() { const inputValue = ref(''); return { inputValue }; } }; </script> ``` I tried to manage the state in the parent component and pass it down to the child using props. When the route changes, I attempt to set the props to the previous input value, but it doesn't seem to work as expected. Specifically, I see the input field reset each time I navigate. Any insights on how to persist the state of child components across route changes in Vue 3? Are there best practices or specific patterns I should be following? Iām using Vue Router version 4.0.11 and Vue 3.2.25. The project is a microservice built with Javascript. Any ideas how to fix this? The project is a desktop app built with Javascript. Has anyone else encountered this?
