@andrzej.fricze pathom and EQL ecosystem are "another approach" GraphAPI's you can do a lot of things that graphql do, things that graphql can't do, and maybe there is things that only graphql do. pathom has the concept of placeholders, that you can use to "mimic" HeroNameAndFriends

[{:>/HeroNameAndFriends [{(:hero {:episode episode})
                          [:name {:friends [:name]}]}]}]

(letfn [(apply-args-in-query [{:keys [query args]}]
          (->> query
               eql/query->ast
               (eql/transduce-children (map (fn [{:keys [params] :as node}]
                                              (if params 
                                                (assoc node 
                                                  :params (into {}
                                                                (map (fn [[k v]]
                                                                       [k (get args v v)]))
                                                                params))
                                                node))))
               eql/ast->query))]
  (apply-args-in-query {:query '[{:>/HeroNameAndFriends [{(:hero {:episode :$episode})
                                                          [:name {:friends [:name]}]}]}]

I see, thanks so much for explanation @souenzzo
