GraphOS: Growing your API
Ready to unlock the next level? We're expanding our API! We'll add another GraphQL microservice, also known as a subgraph, to our growing supergraph. We'll walk through the process of composition and learn about how the router creates its query plan. We'll also get hands-on with local development using Rover.
