Howdy, I setup ring-swagger as the docs explained ( added to deps.edn )

             metosin/ring-swagger-ui                       {:mvn/version "3.20.1"}

(s/defschema User {:id      s/Str,
                   :name    s/Str

                             :city   (s/enum :tre :hki)}})

@dansudol swagger-json is a pure function to create a swagger spec. You need to serve that yourself. See https://github.com/metosin/compojure-api how it uses ring-swagger to emit swagger docs out of compojure routes

we are not using composure for routing but rather just handling routing ourselves in ring middleware , do i need to setup composure or should I return this json and let my front end framework ( fulcro ) show the json as swagger ( I am so confused )

you need to have a route that serves the generated spec as json. Swagger-ui is configured to use that path (for example "/swagger.json") to genererate the ui from. Hope this helps

oh .. ok .. so i would manually set up a public route that served back my swagger json .. from a route named swagger.json

sorta makes sense .. i will try that now

ok .. i have the backend returning the swagger json .. now, how would i get the nice swagger UI look and feel for the front end ?

is there a way to convert that json to html before i return the json ( or instead of the json ) ?
