I have a problem with GraphQL and I want to create a federation with Laravel 9. I use: https://lighthouse-php.com/5/federation/getting-started.html to create monolog GraphQL and created 2 Laravel projects named "a" and "b". they work separately good. "a" project has a person table with schema(id, name), and the second project has a post table with schema(id, text,person_id) I want to get person_id from "a" project with GraphQL federation. As I search for federation in other languages I found this link: https://www.apollographql.com/docs/federation/federation-spec/#type-_service and I defined it to my schema but it shows me that there aren't any @key-@extends-@external,... directive for that. I create a directive with the Laravel command: "PHP artisan lighthouse: directive --argument Key" and I created also it for "extend" and "external" but I don't know how can I write down my code in @key resolver and @extends and @external directives. Can anyone help me?
The necessary directives are available in Lighthouse after enabling federation, no need for you to define them. To aid autocompletion and satisfy IDE plugins, use php artisan lighthouse:ide-helper - see https://lighthouse-php.com/5/api-reference/commands.html#ide-helper
