Worked on the kamilkisiela/graphql-hive repository to deliver a security-focused enhancement for the GraphQL Gateway, introducing conditional introspection disabling. Refactored the existing disableIntrospection configuration to utilize a new disableIf function, allowing introspection to be selectively disabled based on request context. This approach improved the flexibility and security of gateway configuration, particularly for sensitive environments where introspection exposure poses risks. Updated related documentation to clearly describe the new behavior and usage patterns, ensuring alignment with release notes and reproducibility of changes. The work leveraged JavaScript and focused on backend development and API security, addressing a targeted feature without bug fixes.
