Dear all - I have a ring/router that looks like

(ring/router
     routes
     {:exception pretty/exception
      :conflicts nil
      :data      {:coercion  ...
                  :muuntaja   m/instance
                  :middleware middleware}})

I always had the impression that :middleware and :coercion keys on the route itself would override the "global" ones

(def routes [["/post" {:post {:summary    "create"
                       :coercion   coercion/humanized-coercion-options
                       :middleware (middleware/humanized-middleware state) 
                       ...])

Is that the correct position - am I missing something?

Thanks @joel.kaasinen that's eventually what I did.

Yeah, conditional middleware based on route data is the pattern I'd recommend with reitit. When you use middleware compilation, the non-active middleware disappears completely at runtime.

Reading this, it seems to imply that the order is top to bottom, i.e., global first, then more specific later:

(i.e., All the middlewares are applied correctly:)

But you can reverse it:

yeah there does not seem to be a way to "override" - I ended up working on a conditional middleware for exceptions

enabled by a boolean in the route data
