lack middleware to reroute URIs of requests

Instalattion

Get the code from the reposiroty https://github.com/daninus14/lack-rerouter and make sure it is in a subdirectory of the registries of asdf or quicklisp.

Usage

(ql:quickload "clack")
(ql:quickload "lack")
(ql:quickload "lack-rerouter")

(setf *app*
      (lambda (env)
        (declare (ignorable env))
        '(200 (:content-type "text/plain") ("Hello, Compression2!"))))

(setf *compressed-app*
      (lack:builder
       (:rerouter :route-prefix "/assets/" :static-files-path "/static/" :operation :prepend)
       (:compression-cache :cache-path "bin/cache" :static-files-path "/static/")
       (:static :path "/assets/"
                :root #P"static/")              
       *app*))

(setf *clack-handler*
      (clack:clackup *compressed-app*))

;; To Stop the App
(clack:stop *clack-handler*)

Note that this will prepend ”static” to any request which starts with the route “/assets”.

API

(lambda (app &key route-prefix static-files-path (operation :prepend))

Valid operations are :prepend, :replace, and any function which takes a string URI route and returns a new string with the wanted new URI route: (lambda (path-info) (do the magic here ...))

Note that this middleware does not affect the web application at all and only changes the path-info environment env variable. See https://github.com/fukamachi/lack?tab=readme-ov-file#the-environment for details of the environment variable.
