hiccup.core/html returns a RawString, which must be adapted to be a Ring response [0.2.21]

[hlship]

Just started using huff. Problem: my Ring stack blew up because of the RawString instance returned by huff2.core/html.

I added this middleware:

(defn expand-raw-string-body
  [f]
  (fn [request]
    (let [response (f request)]
      (if (-> response :body huff/raw-string?)
        (update response :body str)
        response))))

This should be documented.

This might be an issue with http-kit rather than Ring itself:
