Trouble with bidi routing

routing.clj

;; I have this

(def routes ["/" [["" :ui/index]
                  ["api/query" :api/query]
                  ["api/data-init" :api/data-init]]])

;; And I want to make api/data-init only accesible through POST
;; I tried

(def routes ["/" [["" :ui/index]
                  ["api/query" :api/query]
                  [:post ["api/data-init" :api/data-init]]]])

(def routes ["/" [["" :ui/index]
                  ["api/query" :api/query]
                  ["api/data-init" [:post :api/data-init]]]])

(def routes ["/" [["" :ui/index]
                  ["api/query" :api/query]
                  ["api/data-init" [[:post :api/data-init]]]]])

(def routes ["/" [["" :ui/index]
                  ["api/query" :api/query]
                  {:post ["api/data-init" :api/data-init]}]])

(def routes ["/" [["" :ui/index]
                  ["api/query" :api/query]
                  ["api/data-init" {:post :api/data-init}]]])

(def routes ["/" [["" :ui/index]
                  ["api/query" :api/query]
                  ["api/data-init" [:post ["" :api/data-init]]]]])

(def routes ["/" [["" :ui/index]
                  ["api/query" :api/query]
                  ["api/data-init" {:post ["" :api/data-init]}]]])

;; Also tried replacing `:post` with `{:request-method :post}` in all those cases
;; None seemed to work
;; It either blew up on me or just didn’t matched the route on request

In bidi, a route is a pair, containing a pattern and a handler. For nested routes, you can replace the handler with a vector of routes.

Line 10 fails because post in [:post ["api/data-init" :api/data-init]] is treated as a pattern, not a (method) guard.

Line 14, the [:post :api/data-init] is treated as a vector of routes, and :post is not a route.

Line 18, the 'vector of routes' contains one route, which has a single pattern of ':post', which isn't want you want.

Line 22 doesn't have a pattern.

Line 26 is the correct one:

(bidi/match-route routes "/api/data-init" :request-method :post) => {:handler :api/data-init, :request-method :post}
(bidi/match-route routes "/api/data-init" :request-method :get) => nil

Line 30, see Line 18.

Hope this helps.
