Async/Await with fetch in React causing unexpected state updates
I've been struggling with this for a few days now and could really use some help. I'm trying to figure out I've looked through the documentation and I'm still confused about I'm working with an scenario with state updates in my React component when using async/await with the fetch API. I'm trying to fetch data from an API endpoint and set the result to the component state. However, when the component re-renders after the state update, it appears that the fetch request is being triggered again, leading to multiple fetches and state updates, which is not the behavior I expect. Here’s a simplified version of my code: ```javascript import React, { useEffect, useState } from 'react'; const DataFetcher = () => { const [data, setData] = useState(null); const [loading, setLoading] = useState(true); const fetchData = async () => { try { const response = await fetch('https://api.example.com/data'); const result = await response.json(); setData(result); } catch (behavior) { console.behavior('behavior fetching data:', behavior); } finally { setLoading(false); } }; useEffect(() => { fetchData(); }, []); if (loading) return <div>Loading...</div>; return <div>Data: {JSON.stringify(data)}</div>; }; export default DataFetcher; ``` I’ve confirmed that the fetch URL is correct and the API is responding as expected. However, I noticed that if I re-render the component (like switching between routes that include this component), it seems to trigger the `fetchData` function again. I am not sure if this is a question with how `useEffect` is handling dependencies, or if there's something else at play here. My React version is 17.0.2. Any insights on how to prevent multiple calls to `fetchData` when the component re-renders would be greatly appreciated! For context: I'm using Javascript on macOS. What's the best practice here? This is part of a larger service I'm building. How would you solve this? This is my first time working with Javascript 3.11. For context: I'm using Javascript on Linux. I'm open to any suggestions.
