Overview of Optimized Search Code Structure
Overview: The final structure clearly separates the input handling from the list rendering, optimizing React performance by ensuring that components only re-render when necessary. The SearchPage
acts as the parent that coordinates state changes, while the SearchInput
and SearchList
components are responsible for their respective tasks.
Overview of the Code:
// SearchPage.js function SearchPage() { const [debouncedQuery, setDebouncedQuery] = useState(""); const handleDebouncedQueryChange = (newQuery) => { setDebouncedQuery(newQuery); }; return ( <div> <SearchInput onDebouncedQueryChange={handleDebouncedQueryChange} /> <SearchList q={debouncedQuery} /> </div> ); }
// SearchInput.js function SearchInput({ onDebouncedQueryChange }) { const [searchQuery, setSearchQuery] = useState(""); const debouncedQuery = useDebouncedValue(searchQuery, 800); useEffect(() => { onDebouncedQueryChange(debouncedQuery); }, [debouncedQuery, onDebouncedQueryChange]); return ( <input type="text" value={searchQuery} onChange={(e) => setSearchQuery(e.target.value)} placeholder="Search..." /> ); }
// SearchList.js function SearchList({ q }) { const { data, isFetching } = useSearchSnipps(q); return ( <div> {isFetching ? <Spinner /> : data.map((item) => <FeedItem key={item.id} item={item} />)} </div> ); }
This structure ensures efficient rendering, clear separation of concerns, and improved user experience in a React-based search interface.
Conclusion
This set demonstrates an effective approach to handling search functionality in a React application, focusing on optimizing performance by separating input handling and result rendering. By applying debouncing in the input field and managing state in a parent component, we ensure that only the necessary components re-render, providing a smoother experience for the user.
