I wrote up our experience of how to get Tiptap to play nice with a Go backend server, along with a lot of inline code snippets and a gist with the backend code. Happy to answer any other questions I may have missed in writing it up.
Even if you don't use the Tiptap editor, hopefully the idea of a sidecar container is helpful to someone trying to solve a similar problem of allowing Typescript/Node code to interact with Go.
