During January 2026, this developer delivered Apollo Federation support for the Aidbox/examples repository, enabling federated queries across multiple GraphQL services within the Aidbox FHIR GraphQL API ecosystem. The work involved implementing a GraphQL gateway and creating a Docker Compose setup to streamline both local development and deployment of federated services. Using JavaScript, YAML, Apollo, and Docker, the developer updated and expanded documentation to include federation setup instructions, usage guidelines, and example configurations. This feature improved API composition, simplified onboarding for new developers, and enhanced deployment reproducibility, though no major bugs were addressed during this period of focused feature development.
