How do you fetch data with useEffect?
You can fetch data with useEffect
in React by performing the data fetching operation inside the effect function. Typically, you use asynchronous functions like fetch
to make HTTP requests to an API endpoint and update the component state with the fetched data.
Javascript
import React, { useEffect, useState } from 'react' ; function App() { const [count, setCount] = useState(0); useEffect(() => { console.log( "See the Effect here" ); }); return ( <div> <p>Count: {count}</p> <button onClick={() => setCount(count + 1)}> Increment </button> </div> ); } export default App; |
