Field middleware

Corvis does not include GraphQL support: there is no module, no resolvers, no schema generation and no GraphQL server. Corvis APIs are currently exposed over HTTP with controllers, WebSockets and Server-Sent Events.

There is no per-field middleware.

Alternative

• For read and write APIs, use REST controllers and document the contract with OpenAPI.
• To validate and shape inputs, use corvis::z schemas.
• To transform whole responses, use an interceptor or the corvis::z serializer (see Serialization).
