How to Fetch API Data in React Using useEffect, useState, and Async/Await

A tutorial on DEV Community walks beginners through fetching external API data inside React components using the FakeStoreAPI as a practical example. The guide first explains how JavaScript's native fetch() works with .then() promise chains, then shows how async/await simplifies the same logic with cleaner, more readable syntax. It demonstrates the correct React pattern of placing fetch calls inside the useEffect hook combined with useState to store results, avoiding infinite render loops. The tutorial also covers managing loading and error states to build a more resilient user interface. A common beginner mistake — marking the useEffect callback itself as async — is highlighted and explained, with the recommended fix of defining a separate async function inside the hook.
