How can I fix CORS errors in my web application?

I'm getting CORS errors when trying to access my API from a different domain. How can I fix this?

CORS errors occur when your web application tries to access resources from a different origin. You can fix this by configuring your server to include the appropriate CORS headers.

What specific headers do I need to add?

You need to add the 'Access-Control-Allow-Origin' header to your server's response. You can set it to '*' to allow all domains or specify a particular domain.

Is there a way to handle preflight requests?

Yes, for preflight requests, you should handle OPTIONS requests on your server and respond with the necessary CORS headers.

Can I fix CORS errors on the client side?

CORS is primarily a server-side issue, but you can use proxies or browser extensions for development purposes to bypass CORS restrictions.
