Do you really need to decouple frontend and backend in the first place? Why not separating concerns instead of separating technologies? Tight coupling of UI with database but decoupling of e.g. admin UI/backend from end-user UI/backend. I'm the author of a Node.js RPC implementation (https://github.com/reframejs/wildcard-api https://github.com/reframejs/wildcard-api) and the idea is the exact opposite of what you are prescribing: highly coupled frontend business logic with database schema/queries. Makes things so much simpler, in my experience.
