Backend API integration

Users should be able to use the frontend views to fetch and modify user data in the database based on authentication and authorization. To implement these functionalities, the React components will access the API endpoints exposed by the backend using the Fetch API.

The Fetch API is a newer standard to make network requests similar to XMLHttpRequest (XHR) but using promises instead, enabling a simpler and cleaner API. To learn more about the Fetch API, visit https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API.
