fast-twitch.middlewares.method-override

Usage and execution boundary

For a POST request only, reads an alternate method from the header or parsed params and changes request-method. It also records original-request-method. Compose parsed parameters outside this wrapper.

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

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

(def app (middleware/wrap-method-override 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.
