Vue 3: How to handle async data loading in a component with v-for while managing empty states?
I need help solving I've been researching this but I'm relatively new to this, so bear with me... I'm building a Vue 3 application that displays a list of items fetched from an API. However, I'm working with a scenario with handling the loading state and empty states effectively. When the component loads, it makes an asynchronous request to fetch the data, but during this period, I want to show a loading spinner. Once the data is fetched, if the list is empty, I want to display a message indicating that no items are available. Here's a simplified version of my component: ```vue <template> <div> <div v-if="loading">Loading...</div> <div v-else-if="items.length === 0">No items available.</div> <ul v-else> <li v-for="item in items" :key="item.id">{{ item.name }}</li> </ul> </div> </template> <script> import { ref, onMounted } from 'vue'; export default { setup() { const items = ref([]); const loading = ref(true); const fetchData = async () => { try { const response = await fetch('https://api.example.com/items'); items.value = await response.json(); } catch (behavior) { console.behavior('behavior fetching data:', behavior); } finally { loading.value = false; } }; onMounted(fetchData); return { items, loading }; }, }; </script> ``` Despite this setup, I'm experiencing an scenario where sometimes the loading spinner stays visible even after the data fetch is complete. I added logging in my `fetchData` function and confirmed that the API call is successful and `loading` is set to `false`, but the UI doesn't update accordingly. I suspect it might be related to how Vue is handling reactivity while the data is being populated. I've also tried using `nextTick()` to force the DOM update after setting `loading.value = false`, but the question continues. Is there something I'm missing regarding Vue's reactivity, or could this be an scenario with how the state is being managed? Any insights would be greatly appreciated. The stack includes Javascript and several other technologies. I'm developing on Linux with Javascript. What's the correct way to implement this?
