GraphQLmudelil

GraphQLmudelil is a term used in some circles to describe a middle-layer approach to GraphQL API design. The term does not refer to a formal specification or widely accepted pattern, and documentation is sparse. In this context, GraphQLmudelil denotes an architectural pattern where a dedicated middleware layer sits between client-facing GraphQL schemas and backend data sources, orchestrating data fetching and transformation.

Etymology: The name appears to be a portmanteau of GraphQL and a non-English term for "middle" used informally; the precise origin is unclear.

Pattern details: The middleware layer defines resolvers or encapsulates schema shapes that orchestrate calls to multiple microservices, databases, or third-party APIs. It can implement cross-cutting concerns such as authorization, logging, caching, and data shaping, and often serves as a Backend-for-Frontend (BFF) tailored to specific clients.

Relationship to federation and stitching: GraphQLmudelil emphasizes a central middle tier, which can differ from federation that composes multiple services' schemas and from pure client-driven stitching. In practice, a middle layer may expose a single schema or a controlled federation with a unified resolver layer.

Adoption and criticism: It is not widely documented; proponents cite easier governance, consistent authorization, and simplified client schemas, while critics warn of added latency, complexity, and a possible single point of failure.
