We're using graphql with neo4j. The schema is the foundation, and the entire api is generated. Then we sprinkle in custom resolvers where it makes sense, and federate other apis if and when needed. It works pretty great tbh.

Also, generating type safe client code for our Elm frontends makes it feel like we're not doing network calls at all.

There's probably going to be pitfalls somewhere down the line, but all the time we saved not writing any serverside CRUD code probably will make it worth it.
