graphql

Scope

Covers the GraphQL API surface itself: schema design (types, field naming, nullability, interfaces and unions, input objects, enums, custom scalars, global object identification), pagination, error modelling, writing and reviewing operations, execution performance and demand control, the differences between server implementations, federated subgraphs, authorisation placement, introspection, and evolving a schema without breaking clients.

Facts here are checked against the GraphQL specification and graphql.org, then against graphql-js 17, GraphQL Yoga 5, Apollo Server 5 and Pothos 4 where behaviour differs by implementation. Rules that hold only for one server say so in the same sentence.
