GraphQL: Dynamic Graph: Live-Introspection

[aschaeffer]

Components as GraphQL Type (right, prefixed with a c) and Entity Types as GrapahQL Type (left)

(Visualization by GraphQL Voyager)

Component Types are nested in Entity Types

(Visualization by Altair GraphQLi Plugin)

Note, hat the Dynamic GraphQL interface is additional to the existing GraphQL interface.

Done by using async-graphql 5.0.0

The schema is created dynamically every time the type system of the Reactive Graph Flow changes:
https://github.com/inexorgame/inexor-rgf-application/blob/main/src/implementation/dynamic_graph_schema_manager_impl.rs#L101

The type system itself creates an event that the type system has changed:
#53

The query resolvers are implemented here:
https://github.com/inexorgame/inexor-rgf-application/tree/main/src/graphql/dynamic

The actix-web endpoint executes the GraphQL query using the Dynamic Schema and converts the result back to a GraphQLResponse:

#[post("/dynamic_graph")]
async fn query_dynamic_graph(
    dynamic_graph_schema_manager: web::Data<Arc<dyn DynamicGraphSchemaManager>>,
    request: async_graphql_actix_web::GraphQLRequest,
) -> GraphQLResponse {
    match dynamic_graph_schema_manager.get_dynamic_schema() {
        Some(schema) => {
            let dynamic_request = DynamicRequest::from(request.into_inner());
            schema.execute(dynamic_request).await.into()
        }
        None => async_graphql::Response::from_errors(vec![ServerError::new("Dynamic schema not available", None)]).into(),
    }
}
