How can I fix CORS errors when using the Fetch API?

I'm getting CORS errors when trying to fetch data from an API. What should I do?

CORS errors occur when your web application tries to access resources from a different origin. You can fix this by ensuring the server allows cross-origin requests.

How can I enable CORS on my server?

To enable CORS, you can set the appropriate headers in your server's response. For example, in Express.js, you can use the cors middleware.

What if I don't have control over the API server?

If you don't control the API, you can use a proxy server to make requests on your behalf, or check if the API provides a way to bypass CORS.

Are there any browser extensions that can help with CORS issues?

Yes, there are browser extensions like 'CORS Unblock' that can temporarily disable CORS for testing purposes, but use them cautiously.
