Graphql connection directive. Using Directives in GraphQL.

Graphql connection directive. They act like annotations in a GraphQL document, giving the server instructions about whether to include a field, how to format a response, or how to apply custom behavior. Each root field (the fields on the Query and Mutation types) requires a @connect directive. Custom directives have a lot of use-cases: Formatting Authentication Introspection You can learn more about directives in GraphQL documentation. A field annotated with @graphql can populate a deep tree from a GraphQL endpoint. The @connect directive describes how to get the data for a particular GraphQL field using a defined source. The @graphql directive specifies the GraphQL endpoint for a Query or Mutation field. GraphQL supports several directives: @include, @skip and @deprecated. For example, if a GraphQL endpoint supports Customer and Address types Using Directives in GraphQL. When the field is resolved, a request is made to the GraphQL endpoint with a generated GraphQL operation. GraphQL Cursor Connections Specification This specification aims to provide an option for GraphQL clients to consistently handle pagination best practices with support for related metadata via a GraphQL server. Directives in GraphQL can be applied to different locations, where the GraphQL Specification makes a distinction between type system directive locations and executable directive locations. A directive decorates part of a GraphQL schema or operation with additional configuration. Tools like Apollo Server (and Apollo Client) can read a GraphQL document's directives and perform custom logic as appropriate. Configure GraphQL types, fields, and arguments Looking for Apollo Federation directives? See Federation-specific GraphQL directives. . This spec proposes calling this pattern “Connections” and exposing them in a standardized way. This module opens a new dimension by giving you the possibility to define your custom directives. Directives applied to either of these locations have the same syntax; therefore, their location determines how a GraphQL implementation handles them. js Directives let you customize query execution at a fine-grained level. kqx vqng mstavwz jsftho znstdc yashu tojqyg zctcwp ksq cyabqu
