blocked by CORS policy? CORS Proxy is Solution ๐Ÿ˜Ž

โ“ What is CORS?

Cross-Origin Resource Sharing (CORS) is an HTTP-header based mechanism that allows a server to indicate any origins (domain, scheme, or port) other than its own from which a browser should permit loading of resources. CORS also relies on a mechanism by which browsers make a โ€œpreflightโ€ request to the server hosting the cross-origin resource, in order to check that the server will permit the actual request. In that preflight, the browser sends headers that indicate the HTTP method and headers that will be used in the actual request.

CORS Error Example

๐Ÿค” What is the Solution?

The solution to bypass CORS is to use a Proxy. A Proxy server, that forwards your request as it is.

But, problems with a Proxy Server is to manage the server, optimize the server, handle traffic, use of Kubernetes to minimize bills, and what not.

๐Ÿ˜ญ๐Ÿ˜ญ So what is the solution to this?

    'x-rapidapi-key': 'YOUR-x-rapidapi-key'
  data: {
    url: '',
    method: 'POST',
    params: {},
