Fetch API

Part of the Full Stack Developer Roadmap

In short

The browser's built-in, Promise-based API for making HTTP requests — the fundamental mechanism your frontend uses to talk to your backend's API.

How to learn this

  1. 1Fetch data from your own backend API and render it in the DOM or a React component.
  2. 2Learn to send a POST request with a JSON body and the correct headers.
  3. 3Practice handling both success and error responses from the same `fetch` call.
