Builds high-performance GraphQL Federation subgraphs and router plugins using gRPC and Connect RPC workflows.
Cosmo Connect enables developers to build Apollo-compatible GraphQL Federation subgraphs without running traditional GraphQL servers. This skill streamlines the end-to-step process of defining schemas, generating Protobuf mappings via the wgc CLI, and implementing business logic as either standalone gRPC services or low-latency router plugins in Go and TypeScript. It is specifically designed to handle complex federation patterns like entity lookups, batching, and field resolvers while ensuring type safety across the entire stack.
