Apollo Federation Schema Designer
Official
API Development
Designs, extends, and validates Apollo Federation 2.x subgraph schemas to construct unified supergraphs.
Streamlines the authoring of Apollo Federation subgraph schemas by providing expert guidance on Federation 2.x directives, entity resolution patterns, and composition rules. This skill assists in defining keys, sharing types across subgraphs, handling computed fields, and resolving composition issues using Rover CLI integration, ensuring robust and compliant GraphQL supergraph architectures.
