Over a three-month period, Viaduct maintainers at Airbnb established a robust Gradle-based backend for the airbnb/viaduct repository, integrating a GraphQL API with resolvers, error handling, and dynamic schema management. They developed a CLI schema validator and enhanced build automation, ensuring invalid schemas fail early and improving developer onboarding. The team modernized core engine execution paths, consolidated code generation, and enabled multi-tenant deployments, leveraging Kotlin, Java, and Gradle. Migration to GitHub Actions streamlined CI/CD and release processes. Their work demonstrated depth in backend architecture, schema validation, and test infrastructure, resulting in a more reliable, scalable, and maintainable codebase.

32 Commits • 12 Features
Oct 1, 2025October 2025: Delivered core runtime improvements and developer-experience upgrades for airbnb/viaduct, focusing on reliability, performance, and faster releases. Engine wiring with migration to engineExecutionContext.fieldScope modernized execution paths and laid groundwork for future optimizations. KillSwitch enablement with instrumentation fixes reduced rollout risk. Schema directives collection and dynamic schema propagation into checker executors/providers, with expanded test coverage for appliedDirectives, improved validation accuracy in dynamic schemas. Build/codegen consolidation and Gradle wiring merged codegen into core and added tenant wiring, simplifying builds and enabling scalable multi-tenant deployments. CI/CD modernization and release readiness, including migration to GitHub Actions, docs updates for artifacts, and demo deployment/version bump, shortened release cycles. Additional investments in test infrastructure and context, toBuilder/codegen enhancements, and targeted bug fixes to improve reliability and DX.
