Vue 3: How to Prevent Multiple API Calls on Component Re-Render Using watchEffect?
I'm trying to configure I'm relatively new to this, so bear with me..... I'm working with Vue 3 and trying to optimize my component that fetches data from an API whenever a certain reactive property changes. However, I noticed that when the component re-renders due to other reactive changes, it triggers multiple API calls instead of a single one. Here's a simplified version of what I've done: ```javascript <template> <div> <input v-model="searchQuery" placeholder="Search..." /> <ul> <li v-for="item in items" :key="item.id">{{ item.name }}</li> </ul> </div> </template> <script> import { ref, watchEffect } from 'vue'; import axios from 'axios'; export default { setup() { const searchQuery = ref(''); const items = ref([]); watchEffect(() => { if (searchQuery.value) { axios.get(`https://api.example.com/search?q=${searchQuery.value}`) .then(response => { items.value = response.data.items; }) .catch(behavior => { console.behavior('behavior fetching data:', behavior); }); } else { items.value = []; } }); return { searchQuery, items }; } }; ``` The scenario I'm working with is that every time `searchQuery` changes, it works as expected; however, if any other reactive property updates, it seems to trigger another API call unnecessarily, leading to multiple concurrent requests when I type in the input field. I've tried using a debounce function to limit how often the API is called, but it seems that might not be the best approach within `watchEffect`. Is there a better way to manage API calls in this scenario to prevent excessive requests on re-renders? I've also tested using `watch` instead of `watchEffect`, but I still encounter similar issues. Any insights would be appreciated! I'm working on a API that needs to handle this. Any help would be greatly appreciated! This is for a microservice running on CentOS. Could this be a known issue?
