This looks very interesting! Is it possible to implement this in a node.js web app? Does it work with any build tool? How much latency does it add to a production server?
Meteor is a very strong option. It will build anything you throw at it. It has built-in accounts so you can get your login/auth system running very quickly. It has a lot of options for live data if your app needs it - your users see relevant updates on their screens without needing to refresh the window. It supports React, graphQL, MongoDB, and other view frameworks/databases.
First of all, you're really good at identifying the need for people to be able to answer this question! It's a very good question because often people aren't aware of their own skills. I don't have an answer here but if you could develop one you'd have many customers to utilize this as a service.
I googled "what hidden skills do i have" and found other people looking into this question as well.
Let's say you need to get a field back that is already in the database table, but that wasn't previously returned by the GraphQL endpoint. All you have to do on the front end is ask for it and GraphQL will populate it for you on the server.
