fast-twitch.middlewares.request-size-limit

Usage and execution boundary

Checks declared Content-Length, not actual streamed byte count. Missing length does not trigger the declared-size rejection. Pair it with a bounded reader when the application needs a real consumption bound.

(ns application.middleware
  (:require [fast-twitch.middlewares.request-size-limit :as middleware]))

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

(def app (middleware/wrap-request-size-limit handler {:max-bytes 65536}))

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.
