fast-twitch.middlewares.x-headers

Usage and execution boundary

Adds only the configured X response headers. Settings belong in an explicit options map; using this wrapper alone does not enable all defaults/security features.

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

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

(def app (middleware/wrap-x-headers handler {:content-type-options "nosniff" :frame-options :sameorigin :xss-protection "0"}))

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.

Settings and defaults

Setting	Meaning
`:content-type-options`	X-Content-Type-Options value
`:frame-options`	X-Frame-Options; supported keyword/string representation
`:xss-protection`	X-XSS-Protection value

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.
