How To

Fetch Data using React Hooks

Use the useState and useEffect hooks.

Provide an empty array as second argument to the useEffect hook to fetch data only when the component mounts, and not when it updates.

Using async directly in the useEffect function isn't allowed as the hook returns nothing or a clean up function, and not a Promise.

import React, { useState, useEffect } from 'react';

function App() {
  const [data, setData] = useState([]);

  useEffect(() => {
    const fetchData = async () => {
      const result = await fetch('<url>');


  }, []);

  return (
      { => (

export default App;

React Hooks are not intended approach for data fetching in React, instead use a feature called Suspense.
