add a route that will serve the contents of the file when the url matches “/”

fast-resource does this: https://github.com/pedestal/pedestal/blob/d20065013abf5d3793ae5301e18a2398707fa2a9/service/src/io/pedestal/http/ring_middlewares.clj#L148

This is how i got it working, but it doesn't seem like a reasonable solution

(defn get-homepage [request]
  {:status 200
   :body (slurp (io/file "resources/public/index.html"))
   :headers {"Content-Type" "text/html"}})

["/" :get [(fast-resource "public")] :route-name :index]

::http/resource-path  "public"

I think your supposed to put the resource interceptor in your interceptor chain before your router. Thats how I do it at least.
