HTTP router for Racket
Routy is a lightweight high performance HTTP request router for Racket.
It uses the same routing syntax as used by popular Ruby web frameworks like Ruby on Rails and Sinatra.
(require routy)
(require web-server/servlet)
(require response-ext)
(routy/get "/blog/:name/page/:page" ; eg. "/blog/racket/page/2"
(lambda (req params)
(format "blog:~a page:~a" (request/param params 'name) (request/param params 'page))))
(routy/post ...) ; POST request
(routy/put ...) ; PUT request
(routy/delete ...) ; DELETE request
(routy/patch ...) ; PATCH request
;start server

(λ (req) (routy/response req)) ; routy response
