# Validating route-trees
|
||
|
|
|
||
|
|
Namespace `reitit.spec` contains [specs](https://clojure.org/about/spec) for routes, router and router options.
|
||
|
|
|
||
|
|
To enable spec-validation of `router` inputs & outputs at development time, one can do the following:
|
||
|
|
|
||
|
|
```clj
|
||
|
|
; add to dependencies:
|
||
|
|
; [expound "0.3.0"]
|
||
|
|
|
||
|
|
(require '[clojure.spec.test.alpha :as st])
|
||
|
|
(require '[expound.alpha :as expound])
|
||
|
|
(require '[clojure.spec.alpha :as s])
|
||
|
|
(require '[reitit.spec])
|
||
|
|
|
||
|
|
(st/instrument `reitit/router)
|
||
|
|
(set! s/*explain-out* expound/printer)
|
||
|
|
|
||
|
|
(reitit/router
|
||
|
|
["/api"
|
||
|
|
["/publuc"
|
||
|
|
["/ping"]
|
||
|
|
["pong"]]])

||
|
