Handling CORS Issues in Fetch API

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:


 .then(response => response.json())

 .then(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!
