How to Federate Graphs in StepZen

Assembling GraphQL Backends into a Single Graph with @materializer

StepZen creates a GraphQL endpoint by assembling subgraphs. When doing federation, each subgraph represents a GraphQL backend. In StepZen, you import the GraphQL backends using the stepzen import graphql command, and then stitch them together using StepZen's @materializer directive.

Demonstrated here by bringing a customer subgraph, and an order subgraph together.
