If you are getting this error 'Access to fetch at 'http://localhost:/some/link' from origin 'http://localhost:3000' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled. ' then this video will help you.

But before that let me explain why you get cors policy Access-Control-Allow-Origin' header is present on the requested resource error while making the request, it happens because our frontend and backend application is not running on the same port and for security, our browsers generally do not allow sending a request on the application running on a different port and hence it results into cors policy Access-Control-Allow-Origin' header is a present error.

The solution of cors policy Access-Control-Allow-Origin' header is present on the requested resource error can be solved by 2 methods.

1- Disable cors policy by using this command
"C:/Program Files (x86)/Google/Chrome/Application/chrome.exe" --user-data-dir="C:/Chrome dev session" --disable-web-security.

2. Installing this chrome plugin - https://bit.ly/33oi9zA and this method will work for you in most of the cases as it will help you to disable cors in chrome. It will also help in solving react cors issue.
