Fix CORS POLICY No 'Access-Control-Allow-Origin' header | solved | 100% working

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

*Common Man we should never use this as it would disable the security, best is to use npm install cors, when working locally. Secondly, while deploying you are again going to face CORS issue*
