@yogthos do you mean something like - ["/thing" {:get (fn [_] (-> (response/ok {:foo :bar}) (response/header "Content-Type" "application/json"))) }]

right, except you don't need to set the content header by hand

this is handled by the content negotiation middleware

it checks the accept header on the request, and serializes the response accordingly

ah, I see thank you

how does this affect luminus in the future? https://clojurians.slack.com/archives/C085AR8RE/p1560772063004300
