Question 1

How do I prevent gqlgen from over-fetching nested data?

Accepted Answer

Use custom models that omit fields or mark fields with resolver: true in gqlgen.yml, then implement resolvers to fetch data on-demand, as detailed in the FAQ section on preventing child object fetching.

Question 2

Can I use integer IDs instead of strings in gqlgen?

Accepted Answer

Yes, by remapping the GraphQL ID type to graphql.IntID in gqlgen.yml, but note that the first model in the list is always the default for generated models and resolver arguments, limiting flexibility.

Question 3

Should I choose gqlgen or graphql-go for a Go GraphQL server?

Accepted Answer

Opt for gqlgen if you value type safety and schema-first development with code generation, but pick graphql-go for a more flexible, runtime-based approach without generation overhead.

Question 4

How to handle authentication in gqlgen resolvers?

Accepted Answer

Implement context-based authentication by passing claims through the GraphQL context in resolver methods, ensuring secure access control without modifying generated code directly.

Question 5

Is gqlgen good for large-scale applications?

Accepted Answer

Yes, its compile-time type safety and code generation enhance maintainability for large teams, though the initial setup and configuration learning curve may be steeper.

Question 6

How to disable interface getters in gqlgen?

Accepted Answer

Set omit_getters: true in gqlgen.yml, but this cannot fully disable getters for complex fields like Relay-style Connections, as noted in the FAQ, requiring workarounds.
