Grafbase SDK for Gateway Extensions
This crate provides building blocks for creating Grafbase Gateway extensions.
There exist four kinds of extensions today:
- [AuthenticationExtension]: Authenticates clients before any GraphQL processing, generating a token with custom data for further extensions.
- [AuthorizationExtension]: Control access to certain fields, objects, interfaces, scalars or enums.
- [ResolverExtension]: Called by the gateway to resolve data for a field from a GraphQL subgraph.
- [HooksExtension]: Called by the gateway to perform actions before receiving a request, or right before sending a response.
- [ContractsExtension]: Called by the gateway to identify which elements should be part of a schema contract given subgraph directives and the contract key.
Each extension has its dedicated documentation and tutorial you can follow through.
