Fetching API Data

Connecting React to an API

Most real applications need data from a backend API. React can request that data, store it in state, and render it on the page.

The Standard API Flow

1. Start the request.
2. Show a loading state.
3. Wait for the response.
4. Check whether the request succeeded.
5. Convert the response into usable data.
6. Store the data in state.
7. Display errors when something goes wrong.

Important

Always consider loading, success, empty, and error states. A production application should not assume that every API request succeeds.
