Route Syntax

Routes are defined as vectors of String path and optional (non-sequential) route argument child routes.

Routes can be wrapped in vectors and lists and nil routes are ignored.

Paths can have path-parameters (:id) or catch-all-parameters (*path).

Examples

Simple route:

["/ping"]

Two routes:

[["/ping"]
 ["/pong"]]

Routes with route arguments:

[["/ping" ::ping]
 ["/pong" {:name ::pong}]]

Routes with path parameters:

[["/users/:user-id"]
 ["/api/:version/ping"]]

Route with catch-all parameter:

["/public/*path"]

Nested routes:

["/api"
 ["/admin" {:middleware [::admin]}
  ["" ::admin]
  ["/db" ::db]]
 ["/ping" ::ping]]

Same routes flattened:

[["/api/admin" {:middleware [::admin], :name ::admin}]
 ["/api/admin/db" {:middleware [::admin], :name ::db}]
 ["/api/ping" {:name ::ping}]]

Generating routes

Routes are just data, so it's easy to create them programmatically:

(defn cqrs-routes [actions]
  ["/api" {:interceptors [::api ::db]}
   (for [[type interceptor] actions
         :let [path (str "/" (name interceptor))
               method (condp = type
                        :query :get
                        :command :post)]]
     [path {method {:interceptors [interceptor]}}])])

(cqrs-routes
  [[:query   'get-user]
   [:command 'add-user]
   [:command 'add-order]])
; ["/api" {:interceptors [::api ::db]}
;  (["/get-user" {:get {:interceptors [get-user]}}]
;   ["/add-user" {:post {:interceptors [add-user]}}]
;   ["/add-order" {:post {:interceptors [add-order]}}])]

Encoding

Reitit does not apply any encoding to your paths. If you need that, you must encode them yourself. E.g., /foo bar should be /foo%20bar.
