How do I handle CORS errors in my web application?

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 handle this by configuring the server to allow requests from your domain.

How can I configure the server to allow CORS?

You can set the Access-Control-Allow-Origin header on your server to specify which domains are allowed to access the resources. For example, to allow all domains, you can set it to *.

Is there a way to handle CORS errors on the client side?

While you can't fully resolve CORS issues on the client side, you can use a proxy server to route your requests through a server that you control, which can then handle the CORS headers.
