trailing-slash middleware

This middleware handles Trailing Slash in the URL on a GET request.

append-trailing-slash redirects the URL to which it added the Trailing Slash if the content was not found. Also, trim-trailing-slash will remove the Trailing Slash.

Usage

Example of redirecting a GET request of /about/me to /about/me/.

(defpackage #:app/main
  (:use #:cl)
  (:import-from #:ningle)
  (:import-from #:lack)
  (:import-from #:lack-mw
                #:append-trailing-slash))
(in-package #:app/main)

(defparameter *raw-app* (make-instance 'ningle:app))
(setf (ningle:route *raw-app* "/about/me/")
      "With Trailing Slash")

(defparameter *app*
  (lack:builder
    (append-trailing-slash)
    *raw-app*))
