If your project is static and you make requests to relative paths that are served by a separate API server (e.g.
/graphql), you can still serve those requests from your backend by enabling a proxy. You can do this by entering the path to be forwarded and the full URL of the backend endpoint to forward to, and all requests to that path will be automatically proxied.
You can also add custom HTTP headers for authentication or other reasons. Any request made to the proxy path will include the custom request headers you provide.
