implementing Debouncing Search Input in React Leading to Unnecessary API Calls
I've been working on this all day and I'm following best practices but I need help solving Could someone explain I'm experimenting with I'm working with a question with debouncing a search input in a React application... The goal is to minimize the number of API calls made as the user types in a search box. I implemented a basic debounce function, but I'm still seeing multiple requests being sent to the server, which is not desirable. Here’s my code: ```javascript import React, { useState, useEffect } from 'react'; const useDebounce = (value, delay) => { const [debouncedValue, setDebouncedValue] = useState(value); useEffect(() => { const handler = setTimeout(() => { setDebouncedValue(value); }, delay); return () => { clearTimeout(handler); }; }, [value, delay]); return debouncedValue; }; const SearchComponent = () => { const [searchTerm, setSearchTerm] = useState(''); const debouncedSearchTerm = useDebounce(searchTerm, 300); useEffect(() => { if (debouncedSearchTerm) { fetch(`https://api.example.com/search?q=${debouncedSearchTerm}`) .then(response => response.json()) .then(data => console.log(data)); } }, [debouncedSearchTerm]); return ( <input type="text" value={searchTerm} onChange={(e) => setSearchTerm(e.target.value)} placeholder="Search..." /> ); }; export default SearchComponent; ``` I expected that the `useDebounce` hook would effectively delay the API calls until the user stops typing for 300 milliseconds, but I noticed that if I type quickly, the requests still get sent multiple times. I even checked in the network tab and saw several requests triggered before the debounced value is updated. I've tested this on React 17 and the latest version of Chrome. Is there something I'm missing in the implementation? Any suggestions to ensure that the API is called only once after the user stops typing? I'm working on a REST API that needs to handle this. Is there a simpler solution I'm overlooking? This issue appeared after updating to Javascript 3.10. I'm on Linux using the latest version of Javascript. I recently upgraded to Javascript LTS. Any examples would be super helpful. For reference, this is a production mobile app. I'd really appreciate any guidance on this.
