Could you explain NodeJS + Golang API (option 1)? How should Golang handle the API if I'm using a NodeJS/Express server as well?

Golang + NodeJS microservice (option 2) is the same as the example I gave right? Where the client only communicates with a Golang server, which forwards the request to NodeJS/React for processing. The processed response is then returned by the Golang server.

Golang + JS interpreter (option 3), again the client exclusively communicates with a Golang server. But Golang types are translated to the equivalent React JS components. Then processed with NodeJS/React and returned as a response by the Golang server. Is that all right?
