How to fix CORS error in JavaScript fetch request

I'm trying to fetch data from an external API using JavaScript, but I keep getting a CORS error. How do I solve this?

CORS errors happen because the API doesn’t allow requests from your domain. You can’t fix it with frontend code unless the API supports it.

Try using a proxy server like cors-anywhere or build your own with Express. That way the request goes through your backend instead.

If you're the API owner, add proper headers like Access-Control-Allow-Origin to your server response.
