Hey folks! Apologies if this has been asked before -- I'm investigating what it would take to port a large compojure app over to reitit. Is there a recommended transition process? Is it possible to move one route at a time? Any pointers would be much appreciated 🙂

I did that migration a while ago, as I recall it was pretty straightforward. The main gotcha is to be aware that compojure middleware runs “upside-down,” i.e. the the last middleware in the list will be the first to process your incoming request, etc, where as reitit middleware runs from top to bottom: first in the list will be the first to process requests. Also, if you require [reitit.ring.middleware.dev :as reitit-dev], and set :reitit.middleware/transform reitit-dev/print-request-diffs in your ring/router options, you’ll get a ton of diagnostic in the REPL that’s very helpful in debugging middleware issues. I keep them in as comments so I can uncomment them any time I need to debug.
