Three of them have been controlled by the user: author, main and referencearticle. This shows that the generated type ArticleModel contains several fields. The corresponding GraphQL schema (output from GraphiQL automatic documentation): The fields within this type correspond to the fields and data types defined in the model. This means that you need to ensure that no sensitive data is available, as it could be leaked this way for example, this includes information that could be present as field names in the model definition.įor example, if a user created a Content Fragment Model called Article, then AEM generates the object article that is of a type ArticleModel. To do this, a client needs to fetch the Schema, which contains all the types necessary for a query.įor Content Fragments, the GraphQL schemas (structure and types) are based on Enabled Content Fragment Models and their data types.Īll the GraphQL schemas (derived from Content Fragment Models that have been Enabled) are readable through the GraphQL endpoint.
The GraphQL specification provides a series of guidelines on how to create a robust API for interrogating data on a certain instance. GraphQL is a strongly typed API, which means that data must be clearly structured and organized by type. The permissions are those required for accessing Assets.
Use Cases for Author and Publish Environments You can test and debug GraphQL queries using the GraphiQL IDE. The ability to perform direct queries may be deprecated at some point in the future. The direct, and/or POST, queries are not recommended as they are not cached, so in a default instance the Dispatcher is configured to block such queries. they are managed centrally by AEM as a Cloud Service.The Persisted Queries are the recommended method as: GraphQL Query Best Practices (Dispatcher) With GraphQL you can perform queries to return either: See the () Introduction to GraphQL for comprehensive details, including the Best Practices. See Enabling your GraphQL Endpoint for further details. The path in AEM that responds to GraphQL queries, and provides access to the GraphQL schemas. Using your schemas, GraphQL presents the types and operations allowed for the GraphQL for AEM implementation.
Schemas are generated by AEM based on the Content Fragment Models.The GraphQL for AEM implementation is based on the standard GraphQL Java Library. GraphQL is used in production by hundreds of organizations of all sizes…”įor further information about the GraphQL API, see the following sections (amongst many other resources): It provides an alternative to REST-based architectures with the purpose of increasing developer productivity and minimizing amounts of data transferred. “…a data query language and specification developed internally by Facebook in 2012 before being publicly open sourced in 2015. Put GraphQL over your existing backends to build products faster than ever before…”. “ …an open spec for a flexible API layer. GraphQL provides a complete and understandable description of the data in your API, gives clients the power to ask for exactly what they need and nothing more, makes it easier to evolve APIs over time, and enables powerful developer tools.”. “ …a query language for APIs and a runtime for fulfilling those queries with your existing data. AEM Content Fragments work together with the AEM GraphQL API (a customized implementation, based on standard GraphQL), to deliver structured content for use in your applications.AEM Commerce consumes data from a Commerce platform via GraphQL.Address.java package is currently used in two (separate) scenarios in Adobe Experience Manager (AEM) as a Cloud Service:
