I'm working on a web development project where I'm using the Fetch API to make cross-origin requests to a different domain. However, I'm running into CORS (Cross-Origin Resource Sharing) issues, and my requests are being blocked. I've tried a few solutions I found online, but I'm still having trouble. Here's a simplified version of my code:

fetch('https://api.example.com/data')
  .then(response => response.json())
  .then(data => {
    console.log(data);
  })
  .catch(error => {
    console.error('Error fetching data:', error);
  });

I've heard about using CORS headers on the server side to allow cross-origin requests, but I'm not sure how to implement them. Can someone guide me on the proper way to handle CORS issues? How do I configure my server to allow requests from my domain? I'm using Express.js on the server side. Any help would be greatly appreciated!

mark01 I came across this issue years ago.
I think it's a browser constraint. A security feature.
I tried to find a generic way round it but failed.
Things might have changed since then but I doubt it.
