Vue 3: How to properly implement a debounce function for API calls in a search component?
I'm relatively new to this, so bear with me. I've been struggling with this for a few days now and could really use some help... I’m working on a search component in Vue 3 that makes API calls based on user input. However, I've noticed that the API gets hit too many times while the user is typing, leading to performance issues and unnecessary network requests. I want to implement a debounce function to limit the frequency of these API calls. I've tried using a simple `setTimeout` approach, but I'm not sure how to integrate it effectively within my Vue component's reactivity system. Here’s what I have: ```javascript <template> <div> <input v-model="searchTerm" @input="onInput" placeholder="Search..." /> </div> </template> <script> import { ref } from 'vue'; export default { setup() { const searchTerm = ref(''); let timeout; const fetchResults = async (query) => { // Assume there's an API request here console.log(`Fetching results for: ${query}`); }; const onInput = () => { clearTimeout(timeout); timeout = setTimeout(() => { fetchResults(searchTerm.value); }, 300); }; return { searchTerm, onInput }; } }; </script> ``` However, I’m facing an issue where the API call still fires multiple times when I type quickly. It seems that `setTimeout` doesn't properly debounce since `searchTerm` is reactive and updates instantly. Am I missing something in terms of reactivity? Should I use a different approach, maybe using a dedicated debounce library or a composition function? Any suggestions on how to implement this correctly would be greatly appreciated! The project is a service built with Javascript. Thanks, I really appreciate it! I'm working with Javascript in a Docker container on Ubuntu 20.04. Am I approaching this the right way?
