I’m building a full-stack application and need to connect my React frontend to a Node.js backend that interacts with a MySQL database. Here’s what I want to achieve:

1. Fetch data from a MySQL database and display it in a React component.
2. Use a Node.js server as the API layer to handle database queries.
3. Make HTTP requests from React to the Node.js server to get the data.

I’ve already set up a basic React app and installed express and MySQL in my Node.js project, but I’m not sure how to structure the code for the connection between these components. Could someone provide a simple example or best practices for achieving this?
