This is very interesting.

I have been writing a library [1] to bridge relational databases efficiently to GraphQL APIs, and adopted a similar approach towards eliminating the redundancy in the schema definitions.

I currently rely on io-ts [2] which I also use for runtime verification of configuration options in an attempt to facilitate type verification to both JavaScript and Typescript consumers.

GRelDAL is an interesting project! N+1 problem in GraphQL is difficult problem. It remind me Lighthouse PHP [1] which is a GraphQL framework top of Laravel. Lighthouse handles N+1 problem to create a lot of "union all" queries.
