I can't speak to the entirity of your question, but the last part I will address: "is there no good GraphQL-server/implementation for PHP" There are 2 good PHP servers: https://github.com/Youshido/GraphQL https://github.com/Youshido/GraphQL https://github.com/webonyx/graphql-php https://github.com/webonyx/graphql-php It seems like the majority of the graphql-php community has rallied around the Webonyx implementation, including myself for my WPGraphQL project, a free open source WordPress plugin that brings a GraphQL API to WordPress (https://wpgraphql.com https://wpgraphql.com) As the maintainer of WPGraphQL, I'd be interested in adding a section to the HowToGraphQL resource specific to using GraphQL with WordPress, but haven't had any official discussions with the maintainers of the project yet. There are also implementations for Laravel and other projects, using that library.
