To keep resolvers thin in gqlgen, enforce a canonical package layout that separates generated contract code from hand-written logic. Resolvers should act as a thin boundary, calling interface-driven services and returning domain-oriented results without containing business logic.

The correct gqlgen regeneration workflow involves running gqlgen generate while preserving manual resolver implementations. You must follow a strict reglement that saves hand-written stubs and prohibits committing unresolved panic stubs into the codebase.

To wire a GraphQL handler into an HTTP router with gqlgen, mount the schema using handler.NewDefaultServer and the provided playground. This approach avoids manual JSON parsing and custom field-based routing to maintain standard HTTP integration.

Gqlgen resolvers fill up with business logic when the boundary between contract and implementation is unclear. Enforcing thin resolver rules ensures resolvers only accept arguments, call services through partially applied interfaces, and return domain-oriented results.

Yes, you can use domain-driven design with gqlgen code generation by configuring gqlgen.yml to map schema types to domain types. This setup ensures resolvers return domain-oriented results while relying on interface-driven services for business logic execution.

A limitation of thin resolvers during GraphQL schema evolution is the strict reglement required for re-generation. You must avoid committing panic stubs and carefully preserve hand-written implementations across the prescribed package layout when modifying the schema.
