fast-twitch.middlewares.head

Usage and execution boundary

Runs GET behavior for an incoming HEAD request, then removes and disposes the response body using the original request method. A route accepting :head alone does not implement this body cleanup.

(ns application.middleware
  (:require [fast-twitch.middlewares.head :as middleware]))

(defn handler [_]
  {:status 200 :headers {"content-type" "text/plain"} :body "Hello"})

(def app (middleware/wrap-head handler))

This defines the Ring handler portion. Adapt app through routing/ft-handler or pass it to server/listen!; startup instructions and a complete walkthrough show the surrounding project.

Wrapper order and all middleware families. The function reference below preserves the upstream signatures and source links; helper functions do not all share the wrapper's arity.
