Managing State with TypeScript Classes for API Data in React - Best Practices?
I'm a bit lost with After trying multiple solutions online, I still can't figure this out... Currently developing a React application that interacts heavily with a RESTful API, I found myself needing to manage the state effectively using TypeScript classes. I've set up a basic class to encapsulate my API interactions, but I'm unsure about the best practices for state updates in a way that enhances user experience. Here’s a snippet of what I’ve implemented so far: ```typescript class ApiService { private baseUrl: string; constructor(baseUrl: string) { this.baseUrl = baseUrl; } async fetchData(endpoint: string): Promise<any> { const response = await fetch(`${this.baseUrl}/${endpoint}`); if (!response.ok) { throw new Error(`Error fetching data: ${response.statusText}`); } return await response.json(); } } ``` This class fetches data without tying directly to the component’s state. However, when I try to manage responses in my React component, the user experience feels a bit sluggish, especially when multiple API calls are made. I've experimented with useEffect and state hooks, but I notice that each API call causes the component to re-render, which can lead to performance issues. Here’s how I'm using it in a functional component: ```typescript const App: React.FC = () => { const [data, setData] = useState(null); const [loading, setLoading] = useState(true); const apiService = new ApiService('https://api.example.com'); useEffect(() => { const fetchData = async () => { try { const result = await apiService.fetchData('endpoint'); setData(result); } catch (error) { console.error(error); } finally { setLoading(false); } }; fetchData(); }, []); if (loading) return <div>Loading...</div>; return <div>{JSON.stringify(data)}</div>; }; ``` In this setup, while the loading state is managed correctly, rapid sequential API calls can still make the UI feel unresponsive. I’ve considered implementing debouncing or batching requests but would like to know if there's a more idiomatic way using classes in TypeScript. Would leveraging something like RxJS for handling multiple streams of data improve responsiveness? Or should I refactor my class to adhere better to functional programming paradigms? Looking forward to any insights or suggestions on how to refine this approach and enhance the overall user experience. Has anyone else encountered this? My development environment is macOS.
