How do I use CORS with the Fetch API?

To use CORS with the Fetch API, ensure your server includes the appropriate CORS headers in its response.

What headers do I need to include on the server?

You need to include the 'Access-Control-Allow-Origin' header, which specifies which origins are allowed to access the resource.

Can I allow multiple origins?

Yes, you can specify multiple origins by dynamically setting the 'Access-Control-Allow-Origin' header based on the request origin.

What if I want to allow all origins?

You can set 'Access-Control-Allow-Origin' to '*' to allow all origins, but be cautious as this can pose security risks.
