Handling Multiple Form Inputs in React with useState and Debouncing Issues
I've searched everywhere and can't find a clear answer... I'm working on a form in React where I need to handle multiple inputs efficiently without triggering re-renders too frequently. I'm using `useState` to manage the form state, and I want to implement debouncing for the input values to avoid excessive API calls on each keystroke. Here's a simplified version of what I have: ```javascript import React, { useState, useEffect } from 'react'; const MyForm = () => { const [formData, setFormData] = useState({ name: '', email: '' }); const [debouncedData, setDebouncedData] = useState(formData); useEffect(() => { const handler = setTimeout(() => { setDebouncedData(formData); }, 500); return () => { clearTimeout(handler); }; }, [formData]); const handleChange = (e) => { const { name, value } = e.target; setFormData({ ...formData, [name]: value }); }; return ( <form> <input name="name" value={formData.name} onChange={handleChange} /> <input name="email" value={formData.email} onChange={handleChange} /> </form> ); }; export default MyForm; ``` However, what I'm noticing is that even after implementing the debounce logic, I'm still getting multiple console logs from the API call I have set for when `debouncedData` changes. It's like the state updates are not being batched correctly, and I end up making several API calls when I only want one after the user has finished typing. I've double-checked that I'm clearing the timeout correctly, but I still see the calls firing off more than once. My current React version is 18.0.0. I'm also using `axios` for API calls. Can someone guide to understand why I'm still getting multiple API calls, and how can I ensure that only one call is made after the user has stopped typing? Any best practices for handling this scenario would be greatly appreciated! I'm developing on Ubuntu 20.04 with Javascript. Could this be a known issue? Thanks, I really appreciate it!
